Real Engineering as engineer I love your videos!
Make a video on topic: how much emissions are released when producing an Litium battery for one e-car.
There is a link under the equation on the website.
uum.. where exactly is this car calculation thingy? in the video you say it's at "battery.real.realengineering" and that there is a link in the description.. i don't see any..
have you click more in the desc??
I goofed on that part. I recorded that last night and I am dying sick, as you can probably hear. The link is above.
1:18 this graph clearly shows that we should be running trucks off Plutonium 238
M Goobie imagine if
Pu 238 (88 yr. 1/2 life, alpha emitter) is insanely dangerous to work with. And it has a 200 year bone deposition half-life if you inhaled in an accident, not to mention the chemical toxicity. I've worked with it for space missions.
"battle against climate change". and there fake engineering lost all credibility, if he had any to begin with.
What does that have to do with this?
You cant make plutonium we need hydrogen you can make that
It's halfway through 2021 and there is still no word on the production of the Tesla semi.
Probably pandemic hit hard 🤷
Car production and specially electric ones around the world has been reduced drastically due to covid and shortage of silicon semi-conductors
@L M came here from thunderfoots vid about the new "truck". but the excuse is valid since electric cars are utilising more silicone and its production so its gonna be slowed down. not for 2 extra years tho
Actually we have very accurate news on the production of the Tesla Semi. It is delayed.
@@BakedSalmonela Keep in mind that electric cars need only to move their own mass. The weight of the cargo is minimal. Not so for freight hauling. That's why the cars work to some degree. The trucks will not.
"So we know Energy = Power x Time"

Exact same reaction lol
So Distance x Distance?

1:18 I just love how lithium-ion is barely visible while plutonium breaks the graph 🤣. An excellent and funny way to put things in perspective.
Not really applicable here, but nuclear power is so underrated and overfeared
@@sehr.geheim I agree, it still needs the utmost care and professionalism when dealing with it but it's incredibly safe and clean.
Yes with proper care nuclear can be soooo much more safer than coal power plants
@@sanjay_swain safe nuclear plants are one thing, but I think nuclear energy won't be taken seriously until we find a much, much more efficient, risk proof and time proof solution for nuclear waste. That's where, I believe, most of the reticence comes from.
@@FredGlt depends on what you mean by risks. One thing can't be completely risk proof. Sure nuclear waste is difficult to manage but things have changed since last two decades. Also alternative are not without risks. Anyone working on coal power plants are open to much much more dangerous environment and regulations for those means nothing. If we put coal power plant safety regulations anywhere close to that of nuclear than all the company running those will face criminal charges for unhealthy environment of workers.
Dude you really took this channel to the next level by actually going through a recent scientific paper to explain how to calculate these values and then paying to have a site made to run the calculations. A++
Second this. Keep up the good work.
+Meeks1 that is the minimum states must allow for interstate commerce. Some states limits are higher, in Michigan you can run 150,000 lbs without a permit if you have enough axles
So basically the tesla semi is even more viable if the weight limitations are more lax than was mentioned.
MasterMazeProductions You should thank the internet
Modules run high weight over some pretty shaky bridges. I think 45,000 lbs is about average for a class A load. Unless you are hauling car batteries, or heavy equipment on a specialized trailer, 80K is unusual. Michigan being the home of the auto industry has some unusual requirements, and out west where there is still mining we have some massive payloads too.
Gotta love how the comparison at 1:17 includes nuclear fuel.
"Here you go with your uranium-powered submar- errrr, I mean truck!"
"Great! But where do I refuel it?"
"You don't."
"???"
"We will fill her up again when you come back for repairs in five years!"
"Oh yeah, and in case you get in an accident, a hazmat suit will be provided in the glove compartment"
More like 20 years
Yannick Kuhn well luckily you’d have a few years to worry about re fueling

"Profitability is not everything" Actually, it is. Profitability is everything. If it's not profitable, it will not be adopted.
Tesla fanboys don't understand that getting approval from hippies won't pay the bills
Profitablity shouldn't be everything, it's what got us in this mess in the first place. Because you can sell people bullsh*t as long as you have a big enough fanbase like Elon does.
Sure wish they'd listen to you !!!!
@@tinamoul haha that's funny. Now go and tell this to the companies and see how they laugh at you
Also: he ignored the ENVIRONMENTAL impact, of making 20 tons of battery.
Electric cars are massively wasteful brag rights; build trains.
There is a reason that it is called "payload", which is the component that matters.
Speaking as a truck driver with over 10 years of experience, you can reasonably expect to spend about $34,000 per year on fuel assuming you're averaging 2500 miles per week, and in a truck that average is 10.1 miles to the gallon which is very good fuel economy. That being said the range estimates on these vehicles are extremely limiting in my humble opinion with diesel fuel I expect to get approximately 700 to 800 miles on each fill up. There would need to be very serious changes to improve structure to make this a viable solution particularly for warehouses and loading docks where trucks will spend an hour to two hours sitting and getting unloaded. And don't quote the 30-minute break rule at me because I can tell you from experience it is very rare that you get to choose where to take your 30 minute break. Personally I think Tesla dropped the ball on this in putting its Research into semi trucks, a much better investment would be short-range buses such as city transportation and school buses where the shorter-range and lighter weight of the cargo will offset the disadvantages of battery power.
thanks Mr S looking the get into the trucking buz and the frist thing I looked into was electric rigs
OTR isn't the most important. They can start with the hub model: every day cab can easily be replaced. Every UPS, Lowes, Walmart delivery truck, Amazon warehouse-warehouse truck, Budweiser truck, etc will be electric and there will be virtually no difference for drivers. Sure, some OTR trucking and longer distance trucking will adopt this, but it will not be the primary market. When you factor in fuel savings and the fact that drivers are typically paid by mile… I'm just saying, you might not be happy, but it could happen.
This is exactly what my dad does as a truck driver. I have to wonder if he will drive a BEV truck before he retires.
final mile truckers may adopt it as they will be able to more easily stop and charge their vehicles (i rarely did more than 100 miles a day when driving for jb hunt, most of my time was spent unloading or managing disasters caused by improper warehouse pallet stacking)
I don't think the 30 minute break will matter as much for the truck as you will have to charge longer than 30 minutes to get your full battery back, it would be done overnight while in the sleeper berth, however i don't think that 500 mile range or even 600 mile range will be enough to get between the few charging stations that exist and when we do start seeing charging stations at fuel stops they will likely be charging that electricity at a rate comparable to the fuel you would otherwise be buying thus offsetting their loss and your profit from using an EV
fuel stops are greedy and charge high because they know we have no option other than to buy, and because of this i have no faith in an electric truck being viable without infrastructure overhaul.
couple that with our companies barely being able to run a qualcomm or other ELD, a fully electric truck would be impossible for them to understand and maintain
@@Bucketvidz If you use a 250kW charger (now just two Tesla superchargers), you could easily gain over 100kWh in 30 minutes, meaning that you have another couple hours of driving. That could be done during the break or during loading/unloading. Large hubs can just switch out trucks and leave a truck to charge for an hour. Must large hubs have a few extra trucks anyway.
OAT351 they are meant for long haul. They already have a sleeper and obviously built for long haul. Wouldn’t make sense to design them for local use because the stop and go will seriously drain the batteries a whole lot more than running on an open road. The open road can actually save energy.
You never actually stated what the expected payload would be, he are the payloads:
36 000 kg - 7000 kg - 8000 kg = 21 000 kg for 500 mile truck
36 000 kg - 7000 kg - 4750 kg = 24 250 kg for 300 mile truck
Mika de Grote
Is that good?
Do you know what the usual payloads are for already existing semi-trucks? How does the tesla compare?
Bessenyei Izsák The Tesla would be about the same payload as current trucks.
Bessenyei Izsák we can usually haul 40000-42000lbs depending on how it is loaded and how much fuel we have. Each axle has a maximum weight limit that when added together can't exceed 80000lbs.
that's not bad, isn't it?Especially for the 300 mile variant?
"well-marketed brand"
even though I have never seen a Tesla ad
Every time you see Elon's face or name mentioned anywhere it's an ad. Tesla's marketing system revolves are the cult following of its leader, they don't see products as much as they sell an ideology.
@@BigUriel and that ain't wrong ;)
Yet you’ve heard of Tesla in every way, shape and form. Smart marketing isn’t it...

why in the entire multiverse am I the first reply
@@zenvio just lucky, I guess.
I was a mechanical engineer before the recession and now I’m a truck driver. I have unique personal experience on this subject. Weather will be this trucks down fall. Batteries don’t work as good when it’s cold outside. Also my current truck has a 2000+ mile range and I need every bit of it to do over the road driving. There are plenty of places a battery powered truck will never be able to go.I have personally stayed at shippers for over 24 hours picking up a load in the middle of nowhere in the freezing cold. Batteries can’t handle that environment. Driving 60 miles an hour is downright dangerous. A very slow truck is governed at 62 and those create havoc on the road. The trucking industry is brutal and it will find the flaws wherever they are. That is the reason trucks have not changed much over the years. Not trying to hate on the people who have pre orders in... get your money back if you can and wait till they perfect it first. Don’t be a guinea pig for this experiment. I promise, you will be sorry.
Mechanical engineer and truck drive? Do you flip trucks or are employed by a company?
have you ever owned a Tesla car?
This truck was designed for day load cargo. Not for cross continental cargo haul.
Maybe you missed the fact that there was no space in the back of the cab for sleeping. Are you really a truck driver. Would you sleep in the drivers seat of a day cab? No. I didn't think so.
Most truthful comment I've read in ages. These trucks are a joke.
@@twt3716 Knight-Time equates his experience with cross continental and multi-day trips with a truck that's specifically been designed for local deliveries from distribution centers through metro areas. You know, places where you're not waiting at the port 24 hours for containers from a ship. Pepsi is Tesla's first truck customer and I'd argue that if you were to spend 24 hours parked at their distribution facility, you'd be fired. Tesla are after the day market which is mostly taken by International.
One thing that makes me question his involvement in the trade as a trucker is his 2,000 mile range. Most tractors have 2 tanks, each upto 150 gallons. Using the 95% rule, you never top them off but you also never get the chance to run them completely either because the fuel system doesn't go to the bottom of the tank. It's impossible to get 300 gallons out of two 150 gallon tanks, besides you don't want the stuff that accumulates in the bottom of the tank after a few years. So you're looking at ~110 gallons per tank or 220 gallons with two tanks and that's a push because most won't take them below 1/4 of a tank remaining because it's a pain to prime the system once there is air in it. 220 gallons of diesel will typically get you 7 mpg IF you have a modern truck so that's 1,500 miles max on a good day with not too many hills. With my time at Chevron, their development dept responsible to top of the line oils like Chevron Delo said that most were averaging closer to 6 mpg, giving a useable range of just over 1,300 miles. This was based on their own fleet of trucks and working with Freightliner. If you wanted to be "that guy" that fully filled his tanks and risked running a vapor then close to 2,000 is theoretically possible but the fact is that most won't risk a $300+ bill to have someone come out to put some fuel in the tank, drop the filters, prime the system whilst leaving you at the side of the road feeling like a fool.
His misaimed rants are exactly the same as what people were saying 12 years ago about the Tesla Model S - that they'll never catch on, the industry would never accept them, people wouldn't buy them because of range anxiety, chargers will never be able to charge fast enough. The Model 3 and Y are some of the most popular cars today. The Model S still sells well when stacked against it's gasoline competitors and the soon to be released Roadster with 600 mile range and 0 to 60 setting new standards, even for the base model, it's hard to argue the progress being made. Then again, NASA tried for decades to land a rocket and make it reusable but instead embarked on the $196 billion Space Shuttle program. Musks' Space X achieved the ability to land a rocket in years, not decades.
Using tech from the Tesla cars and Space X, Tesla has promised Pepsi their trucks will not leave them stranded at the side of the road for at least 1,000,000 miles. They've proven successful in an area where you can't afford a single f**k up - space and are applying lessons learn with system redundancy. Multiple battery banks able to power 4 independant motors. Only 2 are required to haul a 80,000lb load.
He also seems to forget that many states have 55mph speed limits for trucks with the majority at 65. So many criticisms in his post that just don't apply to a truck that has a specific use case. Pepsi's first plant to use the trucks are the Frito Lay facility near Modesto - so 55 mph up and down I-5 and Hwy 99 moving potato chips and spuds.
There are still people around that are old enough to remember that it wasn't all plain sailing for diesel powered tractor trailers either. With over 100 years of development to get where they are today, it'd be a bit short sighted to say the least to expect the first all electric semi to do everything at the first try but then again, people always seem to forget about the history, development and money spent getting where we are today. If someone would have said 12 years ago that a 4000+lb electric car could do over 400 miles on a single charge, carry the family in comfort and do 0 to 60 in under 2 seconds and embarrass all the hyper-cars out there, you would have been laughed out of town and told to up your crazy medication.
I'm surprised that the next step wasn't a hybrid diesel electric, just like with trains. Diesels aren't as efficient as electric but keep them at a specified rpm range and they become a useful generator.
Just like with cars, development will take time. Maybe cross continental will never be a thing, maybe it'll be common place in 10 years with new battery tech. Who knows. If you don't try and build it, it will never happen. If we would have taken that approach to things we wouldn't have an internet to post on and would be living in an age where I'd have to go out and club small animals to provide for dinner, ya know.
I wish this channel existed back in the day when I was in an engineering magnet program and robotics team. This is a way more interesting "word problem" than some abstract sphere in a vacuum.
Or a spherical capacitor amiright?
Where did you grow up?
Gi Geo Miami, FL
Cool. Im from LA Ca
Especially if that sphere in a vacuum is a cow.
Routes where there are hills and stopping and starting can not be ignored. This is a commercial truck not a train. Also, batteries degrade with time this may have a very practical effect on range over the life of the truck ...
wouldn't the time to recharge the battery also figure into the economics of the truck ?
I think it was 30 min charging=200miles They said IT in the reveal
@@mihaimera7837 so how many batteries per truck will be required assuming an intercity truck might have 5 different places it regularly loads or unloads ?
You have to realize by law truckers have to take a total of 8hr rest time every 24hrs in the US. Depending on how the trucker splits this up(not going into the details on how they can too much to explain) they would have enough time to recharge the batteries. The main problem would be finding a truck stop that has the recharge stations.
@@NMonterosso It's irrelevant because the Tesla trucks aren't over-the-road trucks. They are daycab trucks. Basically, they will come back every night in a yard.
There is a market for that, but not that big : companies using daycabs like FedEx, UPS, YRC, etc, use them during the day to do deliveries and pickups in an area with one pup trailer, and use them at night to pull doubles, switching in the middle of the road with another driver and come back in the yard with a double from another city. No need to have two different trucks for night and day. Just switch the drivers.
But it's not possible to do that if it needs 8 hours to get back on the road.
@@martinpenwald9475 you must have misunderstood me I'm saying they could be used for over the road if like was said only need 2 hrs to recharge. As I said over the road truckers have to by law rest 8hrs every 24hrs they don't have to do all 8hrs at once. So what I was saying they could use that time to recharge without losing any time on the road.
Plutonium powered truck! Dude you are visionary.
More like Hydrogen
Imagine a crash-site cleanup, lol
I think it's been tried....
No he's russian
Specific energy so high you need Chuck Norris to drive that one
I'm pretty sure real engineers were behind these trucks... so i don't think they would waste millions on a truck if it didn't work.
And this guy don’t know shit. He got the definition of energy density wrong.
Most engineers will say anything if their career is in jeopardy.... The only thing that really maters is the short term profit thats made..... because it's not hard to figure out that shit in this world is getting worse... not better. So it's like "get what you can now" who cares about what happens later.
you got a point there ^^
@@dohc22h where did you get this from? "most engineers will say anything if their career is in jeopardy?" .. Oo
if engineering was as easy as just using an oversimplifyed formula like this one I would stay at home. I don't work at Tesla but I am sure there are plenty of validation gates before funding developments in order to save money from bad design and bad concepts. Tesla seems to do it right so far, SpaceX too (even if they are separate companies I assume that key decisions goes through the same process on both companies).
Who taught you how to spoke?
Dude ur like my old physics teacher... He adds two simple equations to the formula then adds something that I've never seen before.
The most important thing Musk fails to address, LOAD CAPACITY, which for an electric truck will be abysmal.
The batteries alone will weigh 1/3 of the maximum 36 ton limit, so you'd be lucky to have a load capacity of 6 tons for the actual cargo, less than a third of a conventional truck.
Musk is nothing more than a salesman.
Lets not forget the more you weight you place on the truck the more energy and less range you are going to recieve in total
I see the major use for electric trucks is for in-city transportation, which is a lot of stop-and-go travel. Diesel engines don't like changing often, but batteries have no problem with it. So intercity semis on the highway will still be diesel (since they can also be 'recharged' quickly), while intracity will be electric.
I am with you there tains should be updated for interstate travel we wouldnt even be having this problem
You comin from Adam Something?
if the dont switch to less polluting alternatives, then they should pay for the pollution they produce. It's called a carbon tax. That would change the whole dynamics and why electric trucks are the future, its not just hype,
My company actually has electric semis in testing and Tesla’s on order . So far 125 miles per charge and 5 hours to charge even if the Tesla is 50 percent better it’s completely unusable. Local trucks run two shifts day and night 800 to 1000 miles a day and often need to drive a pto to unload product. Long haul trucks will run 600 to 1200 miles a day with either solo or team drivers to make things worse there is a crippling lack of parking which means you will not be able to build enough charging spaces without a lot of concessions being made on building new truckstops half the time drivers just end up sleeping in their customers lots . And if you think those same customers who get upset if pressure is put on them to unload in a timely manner will put up charging stations for random trucks your mistaken . Currently diesel trucks like the cascadia equipped with the 120 gallon tanks will go 1920 miles on a filling not 900 . Energy density will have to increase dramatically and there will have to be major infrastructure investments to have electric semis . And even then they won’t be able to be used in several vital applications that require the use of a pto they will be completely unworkable for agriculture applications for quite some time . You can mandate electrification all you like in the case of California but it won’t matter once it becomes clear that doing so would decimate food production.
" So far 125 miles per charge and 5 hours to charge even if the Tesla is 50 percent better it’s completely unusable"
Tesla would be like 400% better. It is for sure useable. Even 125 miles is useable. We have trucks in my city just delivering new goods to stores in the shopping streets. Those arent even going 125 miles in a whole day.
@@simonquvang6073 no it won’t they don’t have any special new magical battery chemistries they are working with the same battery companies that everyone else is . My company ordered Tesla’s in 2019 we are still waiting.
@@simonquvang6073 and even if it was 400 percent better which is impossible with current technology it’s still not capable of doing most jobs in the industry. That would be 500 miles under perfect conditions when the average truck is driving 600 to 1200 miles a day plus powering auxiliary equipment. All the agriculture in the country would shut down without specialized trucks that use power take offs for loading and unloading.
@@simonquvang6073 you're living in a fantasy world and you need to come back to reality. In what reality does Tesla have batteries that are 400% better? And what's the point of having a truck that can only deliver to "shopping streets"? Yes lets replace versatile trucks that can travel both short and long distances so Simon can j/o to his stores on shopping streets getting goods from a truck that picked up a container through a magic portal.

2092 Elon Musk: “Boys, we’re going nuclear”
Makes sense.
Khoa Do lmao
Karthik Ramachandran nuclear technology is kinda outdated
@@foxgaming76yt24 old ≠ outdated
Khoa Do Not cheaper. A website said:The cost of generating solar power ranges from $36 to $44 per megawatt hour (MWh), the WNISR said, while onshore wind power comes in at $29-$56 per MWh. Nuclear energy costs between $112 and $189.
But technically, nuclear power can be an energy source that is better for the environment, but it’s non renewable energy, so eventually we’ll run out. Nuclear stations needed to produce nuclear power can also be dangerous, like what
happened with the nuclear explosion. So in my opinion, no, nuclear propulsion is not the future(except maybe in spacecraft).
4 years later, Tesla still cant solve this problem and has no feasible business case for the Semi. but its ok they deserve a stock price that is 1000X their earnings
U forgot 2 things for example how bit stupidity of Tesla is their stock value exceeds their actual value by a huge factor. Taking that furth Tesla has let's be royal 1 to 3% of car market share yet are more valuable then ford Volkswagen or any other car brand whiles having not 1/100th in assets.
Also all Tesla does outside child labour and poluting the planet 100 times over with their lithium mining. So that already is cause for concern and the biggest scandal of all electric car bullshit. Instead of gasoline now u just use coal from a powerplant hardly any better then diesel or gasoline even if u don't count the position of production it's not worth it
@@nick230699 Telsa has no child labours and phones and laptop uses way more lithium than all Teslas made combined.
Except they do as lithium is mined by children but sure besides that does that matter phones don't advertise that they intend good and do the worst do they?
@@nick230699 Unless you're planning on discarding all the technology you use, I'd suggest taking a few more seconds to use your brain before slagging off anyone else, individual or corporate, for utilizing lithium. One beneficial thing Tesla is doing is starting to integrate batteries with a chemistry that doesn't include Cobalt, a metal which is almost exclusively mined in two locations which both utilize slave labor.
@@nick230699 America doesn't have many coal power plants. Almost 70% of French electricity comes from nuclear power. Denmark gets a bit portion from wind power. So no they are not just using coal.
From the future here, the energy density has gotten a lot better
There are rumors based on the new Cybertruck that Tesla has made a leap in energy density. Currently they are upgrading the Model 3s with new packs that have less cells and more kW. Range on the SR+ went from 240 miles to 250 miles with a reduction in cells.
@@JT-xq2hv for a truck its still wont be enough , but for a small car its ok, keep in ming there are trucks that travel in the bush or in non habited zones with about 2000 miles range they dont need to worry about battery charging

Le Chat Botté semi truck drivers usually have trips ranging around 250 miles fathers new truck will be able to go 500 miles w one charge (about 45 min)
Try to remeber that some us lorry drivers care about being able to merge onto a highway at soemthing faster than 40mph and we would love love love to do 60-70mph uphill.
Ya I love the random pretend logic of "They are going slowly because they like it!", amazingly and stupidly hilarious.
Nøderak a Tesla semi can actually outperform any diesel powered semi on the market so....
EV Semi-Truck drag racing.
Make-Trix Trucks on the market are built for transport, meaning they are lighter than any Tesla semi with similar power and speed. If you want to merge faster than 40mph with a Tesla, you'll have a lot less load with you, making less money, driving a more expensive truck, having a much smaller radius, not being able to charge as fast as a conventional truck can refill on fuel.
Let me put it this way: I will bet you 5 billion dollars I can get from Los Angeles to New York in with a load of 25 tons in a conventional truck a lot faster than you can in a Tesla.
But he will if someone decides to take him up. Charge time versus filling a tank, assuming he finds large nozzles (Which he will if he's a trucker in his turf, and all the areas he knows truckers from that he's conversed with) and fast pumps, he fills his energy storage stock faster than the tesla driver. If he's allowed to drive nonstop he wins the bet and even if he isn't there's and almost 100% certainty he does because the infrastructure required for the tesla truck is anemic at best. Diesel cross country? Piece of piss that's just normal. Infrastructure for diesel has 100% coverage because MARGINALLY intelligent tank management will get you anywhere without running out of diesel.
Plutonium trucks when?
Future Hindsight still costs less than a Bugatti Chiron or Ferrari Enzo, and those are petrol!
what would be more reasonable is a nuclear powered one and even then just 1 accident with a truck powered by URANIUM and there goes an entire city block for a few years
Veroxeon a car is a car, but a pound of plutonium is a defcon 1 threat that can grant you autonomy. Better value for your money!...also you can give people cancer even faster than reading this comment
Veroxeon NOW you're on the right train of thought!
Who said that plutonium cost $2,500,000 per pound?, thats bullshit, let me explain it
the cost of that is assumed the value of 1KG of plutonium if you sell every kWh at the same price that cost a kWh of oil, or coal, so divide the cost of 1 kg of oil by the energy density and then multiply the kWh's to the energy desnsity that a kg of plutonium releases by fission, that is an staggering 23GWh, or 23,000,000kWh
the energy density shown in the table is the energy that Plutonium 238 releases by it's decay heat, Pu-238 is almost exclusevely used in satelites, and space probes.
1kG of 5% enriched Uranium (5%Uranium-235) costs 800$, but Plutonium? plutonium is free, is created when U-238 gets a neutron.
Another question is : if the goal is to reduce carbon dioxyde emissions, why not to simply build electric train lines ? It's even more efficient than a Tesla semi-truck, the technology is already here and it can handle huge loads over long distances. Local deliveries does not need 500 miles lorries.
and we can put metal wheels on trucks (which are way more durable) and call them trains
@@michakrzyzanowski8554 Super-Trains. Gotta play the name mate.
Found an article stating it should have a 750kwh battery for the 500 mile range truck. That should relate to 11,250 pounds (5.625 ton's) just for the battery.
That's gotta be at least 2 pounds
that's loads of shit, the 100kwh battery of the model S is already only 450 kg heavy, even if you just took 10 of them you would have a 1000kwh battery with less weight than your proposed 5600 tons.
@@LunnarisLP 450kg is roughly 1000 lbs. Plus, the weight of the 100kWh battery in the model S is 625kg (1400 lbs) and the 85kwh battery is 540kg (1200 lbs).
Not sure where you got the 450kg figure. 11,000 lbs is right in line with a 750kwh battery based on Tesla’s claimed battery weight for other batteries.
@@LunnarisLP here, we find another fanboy-ism at action.
Well besides Tesla’s battery weight figure, weight cauculation for the pack is very difficult. It’s not just multiplying by kWh gap. Instead, the heavier the batteries are, the bigger they tend to be, the larger and stiffer the chassis has to be, therefore structural weight is significantly increased, dampers need to be heavier duty, you need more braking by the virtues of safety aaaand we have issues called ‘maintanance’. So it’s not just the batteries alone. It’s all other associated weights that are usually not understood by general public.
I honestly wouldn't even mind getting stuck behind a Tesla semi-truck on the highway. That's a gorgeous looking truck.
FutureNow it would be quieter too.
FutureNow i prefer the old schools. Tesla ain't looking bad either
And it wouldn't emit a bunch of exhaust that gets into your car.
No, the pollution would just shift from the road to the lithium mines and the battery production plants
And the pollution will be more manageable and less pollution in crowded area.

Watched two videos and love your in-depth knowledge on the subjects. Definitely will continue watching first subscription I turned on notifications for. Ever
I'm a truck driver here in the states. For something like this to work for over the road drivers it will need to go at least 650 to 700 miles on a charge. It needs to have the power to carry 40tons up a 7% grade at a acceptable speed. Recharge within 8 to 10 hours during the drivers DOT break period. It will need a APU to recharge the truck if the driver can't get to a truck stop.
watch the video that Musk did ,it's thirty minutes long and he explains exactly what you are questioning. how far can you drive in 8 hrs then you need a four hour break and in that time you are fully charged from dead empty to full three hours
Wucifer slayer well we drive for at 10 to 11 hours. Or anywhere from 600 to 750 miles a day. If they can get it to go 8 hours now then by the time they get one ready for the road it should be able to do 10 to 11 hours. The next problem will be where to charge it. There's already huge parking shortage for trucks. Just not enough truck stops to go around. That's why you see a lot of Truckers stopping on exits or parking at Walmart. There have to be major changes to the infrastructure for this to work with OTR drivers. But local or even Regional trucks could use this. They're home daily so I can see that working.
Wucifer slayer truckers have 11 hours they can drive a day, not 8. We have 11 hours drive time and no driving after 14 hours on duty, and in order to make money you gotta use every hour and minute DOT allows you to drive. Also most OTR guys don't go to one place and go home. Most trucks go to one place, drop a trailer Pick up a new one, drop that somewhere else, etc.
The truck will mainly be for city / local routes. Long haul will still be diesel and someday change to hydrogen I'm sure
Right that remains to be seen though. If it makes more money for truck Companies they will use them. However the stat that most trucks go 250 miles a day or less may be true, but that doesnt mean they Go home at the end of the day. They simply are just making more stops, and doing more back road driving. If it were true that most trucks do a route and go home, I'd be living in a utopia as a truck driver cause that's the ultimate goal to find a home Daily route that pays well. Most of the jobs that are home Daily don't pay well, And are companies I don't see spending the loot on a fleet Of these semis. With these trucks Tesla should also be looking at class b straight truck vehicles which are home daily, and don't have very long routes. They tend to have specialised equipment built right into the truck and they could be what makes up a large percentage of these statistics their using.

Wow, Thanks for the skeptical, yet informed look at this. All I've seen about this was either hype or dismissal, so it is great to see some scientific thinking on it. Keep up the great work!
Yep kinda sad the batteries themselves will cost more than a traditional one. Also cost not shown here is how many time you'll need to replace those batteries because of battery life being reduced as the batteries age.
Let me tell you as an experience diesel enthusiast (I love bio-fuel as it's carbon neutral). Trying to remove my bias.
Those trucks, especially the older ones with older transmissions and engines that are inefficient and very dirty can be cheaply rebuilt from the ground up, engine and all. She'll usually last you around 350,000 miles or more before another rebuild. You can easily rebuild a semi truck engine and transmission from before 2000 for less than 10K USD.
And those engines can be rebuilt almost indefinitely.
They are heavy, durable, cheap and powerful. I think Elon should try bio-fuel instead. It's cleaner and carbon neutral. Electric cars maybe. But I saw this coming years ago. I don't think electric trucks are a viable alternative. Pure biofuel is. Besides electric trucks are no cleaner if your fuel source is natural gas or coal. Renewables like solar and wind can't deliver, no matter how much gov subsides you give them. Those companies love you're tax dollars. Seriously we need new nuclear plants more than ever.
I'm taking this as you think I'm some idiot with no brain? The truck market isn't very complicated, it's just extremely competitive. That's why most trucks are very modular and adaptable to god knows how many needs and wants. One disadvantage I see it no rear view mirrors, a central seating point (which hampers a trucker ability to see certain stuff like grandma's mini cooper) Those screens up front will burn a truckers eyes at night if that's his driving style.
This year solar dropped below everything else. Coal, nuclear, hydro, even gas and wind. I'm not sure why you think it is dead without subsidies. If anything, just remove all subsidies (like coal subsidies).
Solar can be a lot cheaper if they don't put a tariff on chinese solar panels, at any given moment China can flood the world with solar panels that would drive coal out of business
Oh um BTW do you know what's a byproduct of making solar panels.
TOXIC WASTE
@realengineering Watching this in my truck. If this could be a viable option, I would absolutely take it.
Thaumstein, a while ago Nikola motor company unveiled a hydrogen electric semi that already had the energy density issue taken into consideration. There was a logistics system to allow divers to find loads for return trips even. Also, the company is working on installing hydrogen infrastructure to allow immediate fill ups.
Our Electricity power plants are mostly Coal and Oil, so.....Electric cars certainly isn't helping till we get off these.
nonsense. This tuck will not be viable in the trucking industry with the exception as a class 6 of class 7 trucks running hot shots. I just don't see it being able to stay charged for 14-16 hours a day with the heater or the AC going. And let's face it 500 miles will not work for an over the road truck. That range is a total joke. When Tesla gets a truck that weighs close to 17,000lbs and can operate in any terrain with a 700 mile or more range then I'll start thinking this is viable.
Relax, Shawn, I said "if"
Wow dude, I don't know who jammed a stick up your ass. Your comment is nothing but antagonizing. Way to contribute, hypocrite.
You didn't consider climate control in the cab which greatly reduces range. Also, refrigeration needs would severely limit the range. These will only be used for short trips and production has already been put off until at least 2020 - if they ever get made before Tesla goes bankrupt.
2022 as it happens. Fortunately for early, newly wealthy investors of Tesla, like myself - an unlike your assertion. Tesla was never really in any danger of going bankrupt, though as always with any company it was theoretically possible. As someone who reads their financials statements quarterly, I can assure you it's a long distant notion, they are more profitable than any other car company, have almost zero debt (unlike the rest) and have a huge war chest, which is accumulating rapidly. A bit like my overall net worth.
@@mrjonnylowes Elon has said that they were close several times, of course not now that they have high revenue. If it weren't for government subsidies and the out of control fiat currencies they probably would have, but survived it just like many companies do.
@@mrjonnylowes How is your finical analysis now. I don't think you considered that Tesla is a celebrity stock, and the celebrity of Elon Musk is in bear condition right now.

Hopes for future returns were based on speculation of future developments of cheaper vehicles, semi, truck, and FSD to be available and appealing to the market.
Can you make an updated video with the New info and videos we have?
Dude. You forgot about the regenerative braking, and the maintenance cost of a conventional truck. Those are two very big cost savings, and are a large reason why Walmart and Anheuser-Busch have made such large orders for the Tesla trucks.
Regenerative braking is figured into the equation he shows in the video
500K? Miles right? My people carrier is really struggling to get past 80K. The competitiveness of the Tesla truck must depend on the battery life. ie is it 10years or 100,000 miles? Battery lifespan is usually dictated by number of charge cycles, so the mileage will dictate this. If you need to change the battery 4 times in the life of the truck then that is a huge extra maintenance cost.
Maintenance cost. What instead of an oil and filter change we change a burnt out electric motor and more wiring to go brittle/rub through.
Wow. Like everyone who replied to my comment is a truck driver. That’s kinda interesting. Ive been watching Tesla as a company for a long time, and I love having conversations about it, so I’ll try to address some of the things you guys have been saying. I haven’t heard anything about the batteries only lasting 10 years. That doesn’t sound like Tesla. But even if that is true, battery density is quickly improving, and batterie cost is really going down (mostly thanks to Tesla) so replacing a batterie after 10 years probably won’t me that bad, and you probably won’t need to replace it again.
I guess I didn’t hear the part where he talked about the regenerative breaking, but that greatly reduces the size of the batterie needed. As far as maintenance, I’m referring mainly to the fact that the Tesla trucks don’t need to have their break pads replaced for 1,000,000 miles (again because of regenerative breaking) and just basic maintenance that gas vehicles require that all Tesla vehicles don’t. And even if those repairs can be done at a scale that they are cheep to do, not doing them at all is still a lot cheaper.
Walmart etc are virtual signalling.... it is great advertising. Plus they are so big it is not a big risk to them to make the noises that they have to date

Keith Schricker not really, they did talk about “megachargers” that charge 400 miles in 30 minutes
anything under 1300 could be easily used to move trailers already carried interstate by diesel trucks. Not all truck transit is interstate, and just having that kind of tech could replace many many more trucks used for hauling plant around town. Theres a guy I know who spends almost $1000 every time he fills his truck, and being able to charge it overnight would make a massive difference for him since he has to fill it once a week at least to drive his digger around.
More than 600 if you convoy. Thats also worst case scenario. 60mph with 80,000lbs.

Grafeno or micro turboshaft electric generator is solution for autonomy or weight.

I suppose you could make the truck limited in fuel but you would need to use standard gas from a gas station for it to work. You could also make the truck silent or have a custom engine sound.
1:22 I like the fact that you said plutonium as a specific energy.
super aceleration can be use to unload the truck. Just unsecure all the cargo and then put your foot down. Truck goes forward, cargo stays in place, it just needs to drop 2m ;)
😆😅😅
It doesn't need to be that complicated. You need about 100kw to move a very aerodynamic truck down the road at highway speeds. 11 hour shift needs about 1100kwh. Your numbers are way off on the weight and power required 1/2 the load will still require about 80% of the energy. 5kg(5kg per kw of battery pack) x 1100 is about 12000lbs for the battery pack. Weight saved by placing the motor closer to the drive wheels and simpler transmission will be about equal to the motor weight. Weight saved on engine and fuel will be around 4000lbs for a loss of around 8000lbs or 20% typical capacity. For many loads, you are fine with a 40ft box holding 30,000lbs, so it is quite doable. Electricity is about 1/4 the cost of diesel per kwh, so at $3 per gallon and 8mpg(really aero truck on flat highway), you save about $.28 per mile. 150,000 miles a yearly saves just over $40k in fuel. With batteries at $300kw, you have a $300k battery pack that needs to last 7 years to break even(assuming 0% interest). With the money saved on 40qt oil changes, Apu and other related items, we are close to where an electric truck starts to make sense. In 10 years it will be the more efficient option for sure.
beautiful analysis, agreed completely, and while it may take 10 years for the technology to become economical, someone needs to take the risk in starting the transition, that's why Tesla is amazing in my opinion.
Lol, so true.. I'm an American so ft/miles, lbs, Fahrenheit etc are natural to me but even being that as it is I'm in the Engineering field and "US Customary system", "imperial", whatever you'd like to refer to it as, is indeed gross to use and a joke we still haven't gotten over.

Wow, plutonium is awesome and there should be more of it.
Zach Crawford
Just to put it in perspective. Assuming we create a fusion reactor one day. The energy output of that kilogram of plutonium is pretty close to the energy output of a 1/2 gram of hydrogen in a fusion reactor. Yes that’s half of a gram. Approx 2000 times more energy dense from the most abundant element in the universe.
I was half joking,
But I'm all for fusion especially if this www.sciencedaily.com/releases/2017/12/171213104941.htm were to pan out. But we don't have commercial fusion just yet and it will be a while before it is miniaturized enough to fit into an unmanned satellites or space probes. No worries though, I don't really think it should be used in trucks or other earthbound vehicles. Even using it in aircraft carriers and nuclear subs is a pretty wreckless idea seeing as part of their expected life cycle involves being deliberately targeted for destruction.
its radioactive you idiot!
One massive problem, there is NO WHERE on the planet that is safe to store waste plutonium.
Research the ITER - international pilot project to produce sustainable fusion, and create less than 100 lbs. of lvl. 1 radioactive waste per year. Scrapped because U.S. pulled funding (which was about half the project budget).
Also, Plutonium is a key component of thermonuclear weapons, but not fusion reactors. For that the common choices are deuterium and tritium, superheated & supercompressed by pulse lasers.
This channel is just amazing!!
Please do a video where you break down the cost of operating trucks or freight equipment in general :)
Now you add an overhead wire arrangement like they have for urban transport and you have the solution to getting trucks through mountain ranges; grid power for going up the hill, regenerative braking going down the hill. The only obvious flaw in the idea of a battery-powered OTR truck is keeping the driver warm; no waste heat from the engine means that heat has to come from the battery.
Throw in the autodrive system Tesla has and scrap the driver entirely.
Jim's videos or embedded in road?
A small oil fired heater would take care of that.
Oil has an energy density massively greater than batteries, so it wouldn't impact much on the weight budget for the batteries.
...and the motor(s).
Electric motors are about 90% efficient, but still require some cooling.
Batteries are about 70-80% efficient overall, so they lose a decent amount of power somewhere along the way...
There are still sources of heat in electric vehicles.
Any updates planned for this video now that the Truck has shipped to customers yesterday?
short haul/ city - great
mid distance - maybe
long haul - no way (that's realistic for hybrids), at least in near future
3:10 derivations escalated quickly.
I NEED TO GET TO THE SPEED LIMIT IN 2 SECONDS!!!
The batteries take up so much weight payload that it takes twice as many trips to haul ass. None of Elon's yes-men had the nerve to tell him that's a fatal flaw in his whole pitch.
Wait did we factor in the additional battery power required due to the increase in weight of the vehicle from a model S to a 36 ton semi?
Tesla is more than a "very well marketed brand"
It's also a highly government subsidized brand.
Does the calculation take into consideration regenerative braking? Having a lower drag coefficient of a Bugatti isn't a benchmark. Bugatti's are designed to keep cool not be slippery.
Everyone asking if he took into account the regenerative braking needs to rewatch 3:45.
Also what goes up must come down. Sure you gain some power back from braking but you need to climb that hill to go down the other side or you need to accelerate to later deccelerate . Even if you started at the top of a hill, to make a around trip you got to climb it to get back. Nothing is free even if it was a real slow up grad before a steep down, it still uses extra energy over time.
You may only gain back 10% of the power it took to climb or accelerate and im sure Musk took that 10% into account for the range estimate. I bet if you where to drive and not stop or go down hills youd fall short of target range.
But I cant wait to see these trucks on the road. Seriously!
Great! Please make another video 5 years later
"Metric Conversions for the Barbarians" @battery.real.engineering . Love it! :D
Shut up you imperial-dumbfuck.
Why are American trucks only allowed 36 tonnes? Here in Belgium it's 44.5 tonnes and generally our roads are less wide than American roads (because they're older), they have less lanes, and the country is more cramped. The Netherlands is even more dense and there it is 50 tonnes. Australia is like America in a lot of ways (big roads, a frontier, low population density, young country) and they have those massive road trains chugging about.
Tons vs tonnes kid
It was actually an oversimplification. Total GVW is determined by the number of axles and spacing, if i remember correctly. I see trucks ranging from 85k lbs to 105k lbs. I saw a lowboy hauling a piece of heavy equipment that was at least 75k lbs plus the truck and trailor.
um yea with a permit you can but you can only have 80,000 pounds
Hannes D'hondt leuk
Hannes D'hondt the us has more than 300 million people
Things not taken into account.
1. Lifetime of the battery vs engine, ie cost of replacement
2. Maintenance cost (this is a heavy duty application, shit WILL BREAK)
3. downtime for charging (time is money)
4. Availability of qualified shops to maintain & repair
Except Tesla won't sell you parts.
Future Hindsight:
1. Electric motors are not "maintenance free." My father made a living repairing crane motors (electric) that blew up due to too much stress. My computer did the same thing. Think of semis like crane motors or computer power packs. They will be taking a beating.
2. There will be NO charging at the shippers. Most van (box) truck operations are dropping one trailer and picking up another. Flatbeds in mills are usually allowed about 15 minutes to chain and leave (some mills give you less time) because the next truck needs to get on the dock so the crane can load them. Most commercial shippers (like grocery and department stores) don't even want you on the property when you run out of hours of service, let alone to recharge.
These are just some of the issues that need to be dealt with for electric to succeed.
5. Who is going to pay for the massive electric system upgrade necessary to support these electric trucks? The trucking companies with the "savings" generated by un-hired drivers and mechanics, aerodynamic and motive improvements? Doubt it.
Mini power plants . . . massive solar collectors near the fueling locations?
How are the Amps going to be stored as they ate collected/created more slowly than it could be disseminated? Lithium? or some new technology that isn't invented yet?
I think Transportation expenses will increase vastly. Electric bills will increase by more than 5 fold.
Im very curious as to how electricity it takes to charge the batteries and how much more greenhouse gases it would produce in the process? (Electricity doesn't come from nothing even though liberal politicians think so...)
I would imagine they are very easy to fix, the battery pack is a bunch of little batteries to replace and the motors are pretty much just replaceable, they are much less complicated than an engine.
The problem is people think as cynics, not entrepreneurs - they contend that an electric truck would need to be able to do everything a regular truck can to be able to sell, when that isn't the case - it only has to be preferable in some situations and then companies that need that will buy them.
A perfect example is manufacturers, especially large scale ones. These are companies that have trucks going from their manufacturing plants to distribution centres, these are known distances and regular frequency trips meaning that the distance and payload can be anticipated and recharging planned. These sorts of companies (beverage manufacturers etc) have pre-ordered many of these.
With the Tesla Semi set to start production this year, I sure wish you would do an update video.
It is Elon....this won't happen. Solar roofs. Fail. Million robo taxis on the road by 2020. Fail. Full self driving. Fail. LV tunnel? Fail. Tela bot? Yeah.....sure. when are people going to realize all Elon is a marketer. His promises always fall short. Can't wait for Tesla to finally be exposed. Wake up people

The range will only matter up to a certain point due to the laws restricting how long drivers can drive for. If it's a 10 hour maximum (I cant remember exact amount) but they could recharge during the night if truck stops were equipped with charging stations.
It is bean 2 years since the anounce and there are still no Gigachargers being built.
I personally think that hydrogen truck being developed by Nicola Motors has more potential then Tesla Semi.
Question, your mean rolling resistance, is that for the entire vehicle or for each contact point/tire?
Damn this video is so detailed. You should be a youtuber!
That 23% of GHG emissions can't be correct. Maybe 23% of GHG emissions from the transportation sector but not from the entire economy. This source says total transportation is only 27% of US emissions. Obviously trucking isn't 80% of all transportation.
TheGerm24 I do believe he was talking about transportation emissions only
It could be in the US. I Mean, like whats the number, five million trucks give or take? Running 10h daily or more I can see it being high
Danny RLM and they only get like 5 mpg
They are no match to Diesel-electric locomotives. One locomotive uses ten times more fuel than a semi-tractor at idle. At full power close to an entire semi-truck tank....per hour.
The railroad industry is the single largest diesel consumer in the transportation sector and aviation takes first place looking at volume.
(Efficiency, as ton of goods per gal used, is deliberately omitted)
Addictive_LiquoriCe the railroad doesn't move anywhere near the amount of goods as trucks do
it's good that someone can explain it clearly
Do you think on the go reacharge options for the batteries would help increase the range while decreasing the battery weight
I'm going to stick my neck out here but I'm pretty confident in what I'm about to say:
That equation is wrong.
The "1/2" in the inertia term shouldn't be there. If it's derived from Energy = Force x Distance and Force = Mass x Acceleration then it should be Energy = Mass x Acceleration x Distance then multiplied by the efficiency terms after it. I see no reason to include the half or am I missing something.
Also there's a velocity term common to all the parts of the equation so why not cancel it out and simplify the whole thing?
because that’s not what the viewers want
The 1/2 is for regenerative braking and to account for acceleration and deceleration. you recover most of the inertial energy you lost by accelerating through regeneration but there's a round trip efficiency to account for losses of energy through the powertrain while spending and regenerating the energy. So that's why it exists. And the velocity in the drag term is rms velocity also cancelling it would make it simpler but harder to explain how you are accounting for each of the forces, hence it exists.
Thank you for listening but no thanks for not reading what the equation actually means.
Real engineering man you are awesome.....
Battery calculator is False, present battery like 125wh/kg- just put on -
Energy Density (Wh/kg) - for example number 1000 and you will see that
1000kwh battery weight 2 tons instead 1ton !!!!
Kloko Loko... Are you sure... ://greentransportation.info/energy-transportation/energy-density.html
nice vibe and good reasoning in his vids. Shame he's as blue pilled as any normy can be.
You do not understand what I trying to say. Calculator value on that page for 947.40kWh battery, weight should be 3947.50Kg instead 7895.00Kg if battery energy density is 250wh/kg, but you can see that value is 250wh/kg but calculator is showing weight like battery energy density is 125wh/kg! That is error in calculation.
Just try to play with numbers on variables- Energy Density (Wh/kg) and you will see.
like he said!
Any updated thoughts? 5-years later and the trucks are in use by PepsiCo...
This is the best science documentary channel on the internet in 2020
Fantastic video once again. I love how much detail you put into every single one of your videos, no matter what the topic is. But what is even more amazing is how knowledgeable you are on each subject. Keep it up bro.

Every time you idiots call bullshit Elon proves you wrong. Pay attention ffs.
Frank Winkhorst Alright then go make a video on why this is bullshit.
I'm a big fan of your channel and I'm glad your original assumptions regarding Elon's semis were incorrect. Just curious..when you calculated the weight of the truck (the "tractor"), did you subtract the weight of the engine and full diesel fuel tanks? Also, when you calculated the grade the truck will have to go up, did you also factor in the regen power that the motors will generate as the truck brakes as it goes down the hill (assuming the hill being climbed is symmetrical).
at 1:26 he says iit's based on the weight of the current trucks without an engine.
So he assumes a lot of extra weight it won't have then (half a tonne + for fuel+tank) and then assumes they don't have a much more energy dense battery waiting to go into the roadster and semi... why is Real Engineering being so dumb?
@@knifeyonline 4 years later, where is Elon with the Semi truck? Maybe the company realized very few people are willing to purchase the Semi for hauling purposes and diesel just makes better business sense
It may fill a niche role between major hubs not too far apart. They could install chargers at the depots where the trucks get loaded and unloaded.
What value did you use for the root-mean-square of the velocity? It does not appear in your calculator, yet it is a cubed (!) term. It should be much smaller than the average velocity.
I am hoping Elon starts focusing on capacitors to supplement the energy architecture. Removing the peaks of acceleration and using the valleys of regen braking will greatly reduce the spiked drains on the batteries.
If you would install efficient photovoltaic systems on the trailer, I would like to know if that changes anything.
I commented once about this for a truck bedcover. I was told the amount it consumes vs what solar charges, you wouldn't notice a thing. However, I read an article not long ago where a car will have solar panels on the roof. So I guess it might help some.
@@Dalej99 Car with a solar panels on top was said to add 7 miles of range for an 1 hour. This is beyond negligible
@@Dalej99 .blow up dolls needs charging.
Videos are great! But, from one engineer to another could we please drop the post-decimal significant figures on both $ and kG? They are almost definitely not significant and detract from the bigger picture you are trying to convey. A few pennies or hundredths of a kG won't change anything.
With all this surface available the solar charging will be a perfect tool.
Bro u can’t just throw solar panels on something and have it give the results you’re expecting
@@KevAlberta If you think you can, or if you think you cannot, you are both right.

unfortunetly the batteries in these cars/trucks hold so much energy that you have to shove it in there with a high powered hose i.e. high voltage/current electrical hookup. Especially for trucks where the profitability is so dependent on the turn around time. There is a reason tesla's are not 'plug in hybrids'. US house plug is only 15 amps, even dryer plug is only 30amps, high perfomance deep cycle batteries need mucho current to charge in any reasonable time. after saying that there is no reason why you could slap some solar roof tiles on there to charge batteries for in cabin stuff, maybe not ac but radio/lights. putting solar panels on the top of the trailers also sounds attractive, but again they would be used every day and one day's worth of solar charge (227 sqft. of solar panels doesnt deliver much) is not enough to power a reefer trailer (refridgerated) and the extra weight of the batteries would further cut into profitablility.
Alexandros R no, I’m only right if I say what I said originally. Aka solar panels don’t work as well as you think. And Just because you want too “think” it’s gonna work doesn’t mean physics will change for you and work the way you want
