First 200 people get 20% off annual premium subscription.
It’s no surprise NASA is developing an electric aircraft. Tesla and SpaceX CEO Elon Musk is absolutely convinced we’ll be flying in long distance electric passenger planes in the future. Companies like Rolls-Royce, Boeing, and Airbus are all exploring aircraft electrification. So what does the future hold?
We collaborated with aerospace engineers, NASA scientists, and veteran pilots to sort through the current electric aircraft research and evaluate the most promising new technologies based on performance, practicality, and economics.
We’ll provide a comprehensive overview of electric airplane technology, discuss the benefits and challenges, and then rank the most revolutionary electric planes. We discuss battery electric aircraft, hybrid aircraft, hydrogen aircraft and everything in between.
This piece primarily focuses on the state of the art in fixed wing electric aircraft for long distance passenger travel. EVTOL’s will be covered separately, as part of our ongoing series exploring the future of electric aviation.

The FAA recently contacted me and requested permission to use this video in official training materials on powertrain electrification. So if you’re here from the FAA, sorry for the bad jokes.
Clever way of letting everyone know that the FAA appreciated your videos.
🤣🤣🤣
Weird flex but ok
Because we all know that the government is worse at everything, including making teaining videos, especially training videos lol
The FAA is going to ask for extended range for alternative landing sites for sure. They are the Airline mafia. And of course they will want to run an environmental impact study on electric engine noise impact on the spotted snail.
@3:28 you said "contrails' think you meant to say chemtrails. Chrmttailsn8ncrease cloud cover by leaving behind a trail of barium
And aluminum that doesn't disappate unlike "contrails".
This is one of those rare cases where I thought "I'll watch a few minutes and see how it goes" and 42 minutes later, I'm still watching.
This is presented far better than most of the big TV science channels manage.
Thanks
agreed
Indeed this was one of the best video presentations I have seen on CZcams in a very long time.
My exact experience with this documentary.
40 minutes of failed tech, one example of a single manned flight, and somehow people are impressed.
@@blandeauxfillaskii7344 After decades of failure, a single flight of 120 feet heralded a revolution in travel.
The date was December 17, 1903. The pilot was Orville Wright...
Good video. My major concern it the extreme “all or nothing” mentality when it comes to “zero emission” and “all electric” vehicles. The hybrid engines you mentioned are good examples of necessary compromise - but such a compromise is unacceptable today. Pollitics of the moment would never accept 95% or 99% electric. Case in point, todays fully electric vehicles could double their efficiency and range with a very small, very simple propane heater (to warm the batteries and passenger compartments - saving precious battery charge for propulsion).
Another day, and I've learnt something new. I had no idea Electric Planes were even a 'Thing' Jaw dropping planes actually flying around, smart people working together. I'm Amazed. Great presentation.
the technologies appear to be much more mature than I had thought. interesting schtuffs.
The amount of information in this video alone is amazing.
Thanks for putting this together
THummbs up for content and your hard work bro...highly educative and and a good combo inbetween debating within and connecting topics
Until there is a significant breakthrough in improving the power density to weight ratio it will remain a novelty. I wish them the best. They also have to figure out a way to ecologically dispose of these batteries along with eliminating the strip mining necessary to obtain the ore to build them.
There will never be mass transit electric planes. The inherent problem is energy density. To get more payload you need bigger batteries, but the extra energy is mostly consumed simply getting the extra battery weight off the ground. For that reason there will never be large or high payload commercial electric planes.
@@TheSterlingArcher16 I think you meant, "never be electric planes without better batteries." There's no inherent physics reason why we can't have very light batteries with ultra-high energy density. Not to say we'll definitely find a way to make them, but it's silly to dismiss the potential for future breakthroughs. If we get a better battery, then a lot of tech suddenly gets practical.
@@cuthbertallgood7781 There are many inherent physics reasons. Chemical storage is very close to the maximum capacity predicted by the theory. Shawn Crawford is exactly right: A significant breakthrough is required, and you can't count on serendipity to develop a technology.
Look at the electrical vehicles we using now, it’s the green power in the name, it will bring us environmental problems caused by batteries production and disposal.
@@cuthbertallgood7781 You're wrong, there is an inherent physics reason we can't have lighter batteries with higher energy densities. It's just chemistry. We can look at all the possible combinations of elements and see what maximum energy density is per gram.
We could POTENTIALLY go to to fuel cells driven by hydrogen - but hydrogen isn't very efficient in terms of generating it. It's made by steam reformation of natural gas - in other words, it's just natural gas with the carbon stripped from it. Making it by breaking down water is around 50% efficiency, and then when you compress it, you lose even more energy.
Batteries won't get significantly lighter than what we have now. We're really close to maximum energy density as it is.
The obsession about having electric everything is misplaced. We'd be better of generating hydrocarbon fuel - we can do that from CO2 and steam + energy. The Nazis did it, over 70 years ago.
Excellent informative and well produced video. Worth the watch if interested in the future possibilities of aviation and electric power.
Thanks for posting.
Comprehensive and well presented coverage of electric aircraft- thank you!
I just came across this channel, and I am impressed about the thorough research you have done on this topic. Good job! I am subscribing.
@@linyenchin6773 It is the message that should be in focus, and not the dialect.
There's a guy in Monticello Kentucky that is building one that is AMAZING!!! I watched the video and my jaw hit the ground when I saw what it did. I love it when average people build stuff like this and their product out does the ones from huge factories especially those that only make planes...haha. This country boy just happens to be very smart when it comes to aviation I guess. Everything about his electric plane out does every plane I saw on this video. It look bad ass also....thats what I like about it the most. It looks almost like a jet. Very sleek and looks super fast.
Rather a lot of ad breaks but a really well-researched and fascinating presentation.Thank you.
Great video. Really like the format. Also you used "comprise" correctly. That won my sub. 😂
Accidentally stumbled upon this video. Never knew such a quality content about electric fans existed. Very informative and excellent content. Well done. Subscribed already and looking forward to more videos.
@@antimanbiden717 You can reach her through her investment Telegram page.
Still a long way for commercial use. Two challenges 1. range 2. payload (ie battery weight impact.)
Just found this video today. Great information and amazing research. Though,one thing I feel wasn't touched on was the cell life of the batteries. There was a brief mention at 39:41, but the amount of battery waste and replacement cost due to limited cell life is another big concern.
I can feel all the hard work behind making the research for this video!! Thank you for sharing 😁😁
Amazing video, so much innovation information in very short time. looking forward for the next level of electric planes with faster speed and longer flight distance.
Great video, Pipistrel has been one of my long time favorite trend setting companies. Although i'll never be able to afford it, i've wanted to fly their planes for a long time.
Fascinating video. Lots of fuel for thought. Got to admire the folks behind all the e-planes. Cool video, Jay & look forward to watching more. It's the future. 🤩👍💚
Instant subscribe based on watching this incredible (now favourited) video that I shall need to watch again. Thank you!
Lots of info in a fairly short Video Great Job!
Excellent narration and editing. Thank you for not having obnoxious, loud music.
Hydrogen (which makes little sense for cars) makes way, WAY more sense for most planes than battery electric.
Actually the energy density of hydrogen fuel cells is poor because of its storage volume. Liquid Hydrogen requires vastly more space and a more complicated storage system than gasoline. It is less efficient than fossil fuels (specifically gasoline) by an order of magnitude because of this. Just do a quick google of energy density, or check out a video by Thunderf00t on the topic. The key is storage methods and volume. Storing gasoline is easier and doesn't require a pressurized vessel. This vessel has to meet certain requirements to store liquid hydrogen (ie wall thickness and material composition). So not only do you have to store more weight via the fuel, but the vessels must also be taken into account, and they are quite heavy.
That Hindenburg thing was a huge success.
@@techhelpwizardgenie3146 I know all this already dumbass... -_- ... I literally said it makes no sense in cars for just that reason. But for commercial planes? It's MASSIVELY better. You don't need STUPID HEAVY batteries that don't lose weight over a flight (which absolutely KILLS battery electric efficiency for aircraft [NOT the amount of watts that actually make it to the electric motors, but the lbs of load / amount of lift provided]), refueling takes seconds, & the necessary hydrogen storage infrastructure is a perfect fit for major airports.
Tanks of hydrogen aren't light, sure, but compared to the amount of Li-Ion batteries you'd need to lift a 747 & have a suitable range they basically weigh NOTHING! And for certain sizes of aircraft, battery electric is LITERALLY IMPOSSIBLE atm due to the necessary battery capacity weight straight up overloading the craft. (Said 747 is almost surely in this category w/ current battery densities).
@@russelllowry1061 ahhahahaa
@Andrew Onymous I’m pretty sure that methane is worse than co2 but I might be wrong
Outstanding production, well done.
It is very encouraging to hear such good news while so many mainstream sources of info focus on hyped up shock and awe bad news.
Yep , this vid answered all my questions that electric aircraft are coming.... but what about the ever increasing weight of the passenger.. Mmm
Less passengers per flight. Solved
🤣🤣🤣
Your mom?
@@turrafirmaguitarchannel 🤣🤣🤣
@@the.mr.beacher so something that cost as much as say a 737 plane that will cost more as a electrical vehicle up front is now supposed to carry 25% the number of people and only have limited range and will also move at 1/4 the speed of current jets? How can that be profitable, would you play 5k to fly from Ohio to Florida and need you to have a 2-3 hour layover and change planes half way through the flight?
9:00 make the wing small and optimise for high speed flight. Use an alternate propulsion system when slow. What happens when you lose all power? You have no propulsion and not enough wing to glide?
Fascinating contribution to this discussion. As I see it, electric aviation is still constrained by several things:
1. The efficiency of propeller-based aircraft greatly decreases with altitude, which means that long-range electric aircraft cannot take advantage of low-drag high-altitude flight like mainstream jets can. Never mind that there is a hard limit to how fast any propeller aircraft can fly. Transatlantic flights in a long-haul-propeller-electric airliner would be tortuous.
2. the aircraft/payload weight ratio is still untenable for high-volume adoption, especially for longer routes. The most optimized revolutionary design from Israel that you mentioned is 60% battery and it only carries about a dozen passengers for less than a thousand miles. It doesn't help that battery mass does not decline with its consumption.
3. Hydrogen is a dangerous fuel. It's basically corrosive and difficult to contain at any temperature, especially at cryogenic temperatures necessary for high-density storage. It's costly to manufacture as well (a lot of the energy put in to electrolysis doesn't end up as hydrogen). Any leak can be deadly to your aircraft, since the threshold energy for combustion is extremely low (you could end up blowing your plane out of the sky just by a tiny hole in a tank).
4. As much as battery tech is talked up, I don't think battery energy density will increase all that much in the future. Li-ion batteries already are pretty dense, considering they are already made of lightweight materials and do not require a reactant to release their energy. (Consider that all jet fuels use oxygen to release their energy - oxygen which is not stored, but simply pulled from the atmosphere.) Safety becomes a big concern once you put too much energy in a small space, especially if there aren't natural safeguards against runaway energy release. Jet fuel requires relatively specific circumstances to combust which are easy to prevent even in the case of a tank leakage. One can't say the same for batteries.
It does not surprise me that this has found appeal in markets where the high ratio of aircraft to payload and the very limited range is acceptable. I do not really see how hybrid or hydrogen aircraft will be more economically viable than jet fueled aircraft when it comes to high-payload or long-range flight. I'm honestly banking on more sustainable sources of jet fuel rather than battery technology. We're literally swimming in sources of carbon and hydrogen, and liquid hydrocarbons are ridiculously practical for storing and releasing energy.
Either way, your video was well written and sourced. Thankfully not clickbaity or hyper-enthusiastic like a lot of fake science channels on this site. Kudos for that.
Magnesium hydride paste is how you safely carry hydrogen.
Hybrid models with pure electric drive will dominate initially. The main objective is to eradicate GA fuel which is leaded. No need for that if combustion just runs genset.
Fun fact: The tip design is more to do with aircraft standard sizes than to do with vortex management.
The only thing that passively reduces the vortexes (hence reducing lift induced drag) is a large aspect ratio, which is a ratio of a wing's length and width, i.e. the longer and skinnier the wing is the less drag it produces. Hence you see gliders have very long skinny wings.
So to solve the issue of lift induced drag you simply have to increase the wings length, however, there are limits to wingspans of aircraft, hanger size limitations, airport limitations and other factors, you can't make the aircraft to wide, or you'll go up into a higher aircraft class and pay more hanger fees and rents.
So manufacturers come up with these wing tips, they effective increase the length of the wing within increasing the total wing span too much, however it is less efficient than just having a longer wing. Hence new planes like the 777x have folding wing tips, theg fold up when in the airport and stored, but fold them down right before take off. To get the best of both worlds.
It's even stranger with private jets, more often than not customers ask for wing tips because they look good, even tho they might actually hurt fuel efficiency compared to simply a longer wing.
Ik the video glossed over it, I just wanted to give extra info.
I’ve almost always sat at the window, and marvel how I can jut sit there and fly.
You mention the lack of noise as a selling point. I LOVE the noise during take off in a big jet!.. I'd absolutely hate to be in a quiet tin can and not have that theme park rush. The rumble, the bellowing engines.. it all makes you really feel how hard you are punching physics in the face to fly in the first place!.
You and I have vastly different loves. I'm not saying it's quiet I prefer, but to me it's not the sound, it's the torque and power. I don't care how you get it, but that feeling of being thrown back into your seat as the plane moves is great. I don't care if it's silent, but over a long enough flight, silence is great. It's why I don't fly without noise canceling headphones anymore.
You seem to enjoy the power of the engines though. Can sound like a beast but if it's got no power, would you prefer an engine that sounds great but doesn't have power? Or a silent engine with massive power? Is an interesting question. One many don't like to answer. Me? Power, give me that power. It's why I'm so fascinated by electric cars.
@@Xyler94 It's both to be perfectly honest. I grew up surrounded by motorbikes. Learnt to ride from a very young age, The feeling of the engine beneath you, the vibration, hence I used the word rumble in my original comment. That is a huge part of it all for me. On a bike you are so close to the machine that you are a part of it, to the point where your body and how you position yourself is integral to how the bike handles. But the noise is also important, the roar of the engines and the wind. It's all part of the exhilaration of the power of motion. Even the smells are part of it. Those distinct 2-stroke & 4-stroke fumes take me back to a hundred happy memories. - I've been in electric cars, sure you have instant torque and that's fine. But it lacks something. Going from zero to fast isn't the whole deal for me I guess.
I just prefer engines to be audible. I could listen to those old V12 4-stroke Merlin engines from Spitfires and Hurricanes just ticking over all day long. I'm not saying I don't like electric motors, they have their place. and the world would be worse off if they didn't exist. I'm just getting old and I like what I like. So I suppose to answer your question - Neither would satisfy me, a noisy low power engine or a silent high power one. Both, to me, would be insufficient to excite me.
I hope that answer helps. May you find many others who care enough to share.
@@RatBagDad "It lacks something" which is that sound you like. You associate fun with loud sounds of engines. It's not bad, but we can't hold onto emotions anymore. Can't have the fun of a car and engine if there's no more planet earth. So while I get the enjoyment, technological advancements excite me much more personally. I really like the bleeding edge of tech, and seeing people tackle this problem is amazing.
All this to say, I get where you're coming from. I just think performance and the way a vehicle moves around is more important than the sound of an engine. Because like I said, would you prefer a nice sounding weak engine, or a silent but powerful motor? Driving fun is more than simply noises, and my gosh I hate those who exaggerate their car's exhaust. Especially on weak engines...

So, did you enjoy the snowjob of Bull Shit of useless grant money projects where the real goal was for the engineers to learn to build with composites, but getting grant money to learn these key modern skills is near impossible so instead try the "electric" bull shit angle instead. Every single engineer knows it is Bull Shit in the real world as everyone has been able to do a performance calculation based on energy density and efficiency going on 80 years now so.... yea.

Nicely done. Thank you I enjoyed the information.
I don't fly at all, but this is a cool idea that others can use. I'm sticking to my truck personally.
You made a believer out of me with this most excellent video. You also made me a subscriber. Thanks!
A believer in what exactly? Electric planes were never impossible, they were always impractical. They still are. The issue is scaling and energy density. Smaller planes are going to be the easiest to make electric, and currently they are slow and of limited range for a 1 seater. The only currently viable passenger plane design that is shown in this video seats 11 people and 60% of its load capacity is battery. That is about as big as an electric plane can get currently. It would take huge jumps in battery energy density technology to build an electric passenger jet with any meaningful capacity and would likely also require structural elements to be able to act as secondary battery capacity. It might not even be possible to do with lithium based batteries as the theoretical limit is about 1/10 the energy density of jet fuel. That means the engine and the aircraft design have to be substantially more energy efficient in order for a conventional passenger jet to be electric. Such designs would also likely be slower, so longer flights, but that is going to have to be a trade off that comes with the technology.
On a side note, nearly everything Elon Musk said at the end of this video is based on his wishes, and not reality. His supersonic vertical take off electric jet idea is about as realistic as the hyperloop, the tesla semi, or the LA loop. The last of which is now "finished" and you can go and look at videos of what it was supposed to be and compare it to what it actually is. Which is to say, it aint ever going to happen, but maybe he will eventually produce something loosely in that realm with far lower performance and claim it as a success.
@@EcnalKcin Senor Mucho Pomposo: Think pretty highly of yourself? You sound like a troll. Are you one?
@@roneagle8038 Well I now think higher of myself than I think of you for sure. You sound like an idiot. Are you one?
@@EcnalKcin there was an argument much along those lines when the steam engine was being replaced by the diesel electric. Many people never wanted to give up steam and said that nothing would replace it. Of course energy density is the issue with batteries, but throwing up our hands and saying we can’t fix it is a self for filling prophecy. With this many people working on it, you can believe it’s going to happen . If we had said that lead acid batteries are the only possible way to store energy and given up at that point lithium ion would never have been discovered. But a great deal of people resist change because they can’t envision losing the status quo or they have too much invested in the current technology to part With what we know is ultimately going to write our ticket to planetary oblivion.
@@sandyt4343 "With this many people working on it, you can believe it’s going to happen" That is not how science works. If it was, we would have a cure for cancer. Oh sure, someday it may happen, but it could be a hundred plus years from now. We are not talking about minor battery advancements, we are talking about something that isn't even theoretical at this point. I would say we are about as close to having the energy density we need as we were to fusion power in the 50's. Maybe further as we at least knew that fusion was possible in the 50's at this time they have no idea how to get the kind of energy density required out of batteries.
"But a great deal of people resist change because they can’t envision losing the status quo or they have too much invested in the current technology to part With what we know is ultimately going to write our ticket to planetary oblivion." You do realize producing batteries actually creates more pollutants right? Also, the energy that charges them still has to come from somewhere, and that somewhere is usually dirty coal plants. Although we actually have a source of mostly clean energy with today's technology in the form of fission power, but most people are ignorant about it. Fission power is less harmful, and more environmental friendly than any other form of energy, including wind turbines, and solar panels, but because there have been all of 3 nuclear meltdowns that resulted in very few deaths and some local environmental damage, everyone dismisses fission power without ever educating themselves on it.
Excellently produced, realky outlined the problems electric aircraft have, thank you really enjoyed this, give one alot to think about...
Fascinating stuff! I'm sure we'll see short-mid-range viable electric aircraft soon. As for long-range, we'll need a battery-breakthrough for that.
I think in the "electric" category, there are already passenger drones. They don't need any specialized place to land. You could land in your back yard. But the issues in the are are still there. Don't want some conventional plane ramming you in the air.
I like the idea of electric airships, because they don't require much energy for lift, just propulsion.
860 lbs of battery for 100 miles vs 318lbs full fuel load for 850 miles.
We need a break through in battery technology before this is even remotely feasible.
Old comment but 318lbs of fuel will not get you very far at all
yup never have beeen about the motor. always has been about the fuel source/battery
@@Crowbar121 that aircraft that was modified was rated for a range of 850 nm on a full fuel load.

yes i love sitting at the window when i get the chance. will sub to this cool channel
This video was very informative on the innovation of electric flight. Very impressive in my opinion. But I'm just a layman in the field while understanding the basics of the technology.
I loved the presentations of the newer technologies. I'm no expert but I understood the concepts and applications and can see that this was a factual documentary . I believe that this technology is about to experience new sciences that will open new doors . Nicola Tesla had the open mind that was necessary to concieve new technologies and others will follow.
This is an insane amount of work for electric planes. Good work man.
Great ideas, inventions and achievements.....one day, the world will get better with energy options. Nice video and is educative. Well done!
With a long enough power cord there is really no limit to how far or how long you could fly this plane. Really awesome.
The longer the cord the heavier it is. 🙂
HA HA HA HA HA HA! Yeah and when they run out of electricity they will have to borrow the battieris out of their lap tops, and cell phones to keep from crashing!!
Absolutely brilliant,learnt so much thanks👍🏻
great documentary. i learnt a lot. so well researched. keep up the good work!
This was a great video! Very well researched and very well done. Thanks!
If we had batteries that would have 100x higher energy density, we'd be set for so much technology change.
Sadly, this is probably not gonna to happen.
Concur on coverage and fidelity. Thanks!
At 6:50, the problem isn't that the JET A-1 powertrain is merely 26% efficient and the equivalently powered electric motor is 90%, which is all well and good; it's when you have to push that aircraft thru the air at 700+ kph that the efficiency gap closes really quick. It's the Cd, or coefficient of drag that is the main constraint you need to overcome.
It's just basic physics. Fix the Cd, and you can solve the electric aircraft problem.
For large airliners to be fully electric, it cannot defeat the law of physics. You will never see an electric airliner with a range of 3,000 miles and/or can fly over 500 MPH. Ground transportation is possible but not commercial air transportation.
The first electric plain did not have batteries on it but those were in fact transistors that transferred the voltage from the electric power cord that it was connected to. It has a 50 foot electric cord and it did not fly at 7 miles and hour but instead blew up after 2 inches off the ground.
Batteries remain the biggest hurdle to overcome. Even short hops are not reasonable. As a frequent business traveler, I know there are weather events that can keep a plane from landing and keep you in the air an extra hour or more. Electric planes cannot stay in the air an extra hour.
as a business man you would well a truly know about turn around times and that is massive for planes they cant sit around waiting for a battery to charge. i live in line with a regional airport run way see them fly over every day they dont spend more then 30 mins on the ground before there back up. and the limited flight time this is one massive problem planes that come here have to have enough fuel to return to there origin airport just in case the weather is so bad and theres no chance of waiting it out they have to go back. also power a small county side city like ours doesn't have the ability to provide the power for a damn 737 size plane.
@@phalanx3803 That's another issue to be sure. Good point. They could probably work around that though by having charged battery packs ready to go, so that ground crews just swap them out.
I am a retired military/civil pilot. The requirement for holding and diversion fuel in conventional aircraft is established by regulation, therefore the same regulations would apply to the energy reserves of a battery powered or hybrid aircraft. Battery exchange on the ground would seem an option but small regional aircraft fly multiple sectors per day. Not only would this require a lot of batteries at various airports but one wonders about wear and tear on critical connectors. The issue of lightning strikes shouldn’t be a problem in the air anymore than for conventional aircraft but I would be interested to see the effect on the lightweight materials used for the structure.
@@geoffnottage8894 lightning strikes is something i have never thought of on a normal plane it goes around the using the skin but and electric plane would need thick cables to provide power to the engines it would need a butt load of insulation to stop it from jumping to the cables on the inside same with the battery's that much high conductive metal on the inside is just asking for lighting to jump. this would be a big problem if not handled properly as most large aircraft get struck around one or more times year. as for the light weight materials yea that can be another problem if not handled properly Bristow Helicopters Flight 56C got struck by lighting on the tail rotor the Composite material couldn't handle the energy and exploded.
Excellent, subbing!!! I fly All Electric RC models. Have only flown Electric models. Brushless motors have really made a high leap in performance just like lite LIPO batteries!!! I have a multiplex
Delta wing that was GPS tracked at 131 MPH about 5years ago. This technology is really coming along fast!!!😉
Too bad it doesn't scale with size, works fine with super lights and gliders but quickly fails for anything larger and heavier as you need exponentially more batteries which quickly out weigh the lifting power.
Yea but they are making unbelievable progress! Look into it deeper, could work for smaller personal aircraft.
@@troy9er they are not tho. At all. Not even close to real engines
Colour me surprised. This video was recommended to me, and from the thumbnail I thought this was absolutely going to be clickbait. Wow it isn't, but what it is, is a fantastic documentary! Super interesting, super informative and super educational :)
Can you tell me where the aircraft in the thumbnail is in the video and what it is in real life ? Thank you .
What a beautiful design! I wished the Beechcraft Bonanza V-tail were further tested as it reduces structural failure of the more common T-tail. Otherwise, I'd like to go back to the tail on the Super Constellation L-1049. But that creates more point of failure and why I love the V-tail Bonanza. Lets do some more stress testing on the V-tail against the T-tail with large passenger aircraft.
Meanwhile, not only 'yes', but 'hell yes' when it comes to flying an electric powered aircraft! Airplanes love to stay airborne, so it doesn't scare me at all. Bring it on Boeing!
Great video! I study a lot on ev aviation and you hit the marks!
Nasa is always at the center or in the conversation on everything flight.
As a tech giant into Space flight and research, I believe they've done a great job keeping up and contributing to the cool things going on around the world.
As always the energy/weight ratio is the killer; we're not quite there...yet, at least. The challenge of making an electric a/c fly could be matched by the challenge of persuading people to climb aboard. Sod that, i'm a bit of a dinosaur i'm afraid.
My favourite type of a/c to be aboard is one with a pair of petrol engines, and with single engine capability.
Well, just add a peddling system on each passenger place and there is your backup ;-)
Yep this is the biggest problem and the only problem to date. The weight of the batteries is yet too high, the enrergy density have to be better and comparable to gasoline.
@@TobiasDettinger no they don't, hybrid approaches work fine.
@@crhu319 This discussions is about fully electric, hybrid are a entire different subject
How about an electric powered glider? And what was that plane with enormously long wings that tried and maybe succeeded in circumventing the planet. I forget how long ago I saw that.
very well done.lots of good info.
What an eye opener video about future aviation technologies. Loved it.
as a slovenian a am proud
this is cool...GIVE THIS DUDE MORE SUBSCRIBERS!
"Ladies and gentlemen, we have an electrical fault. Nothing to worry about though: We have plenty of parachutes."
no, wait. apparently that weighed the plane down too much so we had to throw them out along with your luggage.

@-GinΠΓ Τάο let do the math.
So, a windmill to be made requires
-materials
-energy for processing the materials(including the one necessary for extracting the materials)
-human labor
-also, for farms, location will involve some costs too
-eventual taxes and profit must be added in equation too.
Now, you say that energy alone costs more than the mill can make in its entire life.
Sure, some farms in the beginning got subsidies, so we can pretend that those subsidies covered the difference.
But time for subsidies has gone, but windfarms are still built. FOR PROFIT.
how can you make profit if you pay for energy more than you squeeze out from mills?
PLus.... you say orders of magnitude.
Maybe I got it wrong, but one order of magnitude is 10, two is 100.
So what you say is that, you spend hundreds of kwh, or thousands, to obtain 1 kwh.
Even you got this expression wrong, and what you want to say, that you spend twice as much energy than you obtain, still the claim does not make sense.
nobody puts 2 dollars to get out one. (this if we consider only the energy, but there are other costs too, so, will be many more dollars spent to get out one dollar)
Electric planes ARE NOT the future for global aviation! EITHER we soon see planes that have jet engines running on HYDROGEN or global aviation have to be stopped due to its unsustainability OR we do the best solution. Build a global, continent connecting vacuum based hyperloop. Going fro London to New York in a sustainable way in 35 minutes sounds like progress to me. Additionally it are technology of THIS generation matching OUR needs for a CO2 emission free solution. Same hyperloop can also be used for cargo transport of FRESH agricultural produce so that an orange from California or a sun matured pineapple from Asia can be picked a Wednesday at 12 and be in the supermarkets anywhere in the world the next morning. That will eliminate the, otherwise co2 cheap global fleet of huge cargo ships, and will ensure best quality produce without freezing or gassing processes. Lets ALL put pressure on ALL our governments to pursue that we ALL begin to build on OUR nations part of the vacuum based hyperloop and ALL chip in to connect these under our oceans with tunnel boring machines. It WILL be the best and cheapest solution for us all. We can use current larger airports to as arrival/departure ports for our hyperloops. Infra structure locally will often support that as a optimal solution. Electric planes can have a future as ensuring island nations or remote locations acces to closer hyperloop stations/ports.
WE are running out of time, LETS GOOO!
@@Mike-ox8sq Sure, electric planes cannot compete in long distance routes. But for local flights is feasible. And with some new technologies like microwave remote charging while still climbing, this can go to continental level. And for intercontinental, cheaper solutions may be applied. Like carbon capture. Sure, this will make flights more expensive, but come on, now too many fly because is cheap and they can afford, not because is really necessary.,
Hyperloop is a great solution. I dreamed at it since half a century ago, when maglev was hyped, But the project is massive. There are better ways of spending our resources. Just think how many years were needed for euro tunnel. How many years will be needed for something thousand of times bigger? Sure, will be much narrower, but distance will be orders of magnitude greater. Add the difficulty of depth. And you need o lot of lines. even parallel ones, because you cannot have infinite capacity on a line. And all this for just 2 percent of the carbon reduction.
And your message for getting united in this endeavor is funny. With whom do you want to make this? I look around and see mostly old people. Those educated able to raise and educate worthy people chose to raise too few children. From these few only a percent are driven to work, and they barely maintain actual status while majority is interested only in entertainment. But the vast majority is those who had no access to education, and barely make a living.
By chance I was watching this when I saw your comment. And the questions are simple. How can this economy help the hyperloop you dream? Or, how hypeloop fits here? czcams.com/video/APgzklQZgSQ/video.html
@@Mike-ox8sq why can't we create the electricity with hydro?
@@robinsss Those that have acces to hydro dams can chose to do that but are hydro dams not in general very hard on nature? Off shore windmill foundations actually function like coral reefs in the sense that they begin with attracting mussles, then seaweed and eventually becomes sanctuaries like coral reefs do. Thereby off shore windmill farms eventually actually enhances water quality and supports all marine life. Nothing you can say about fossil fuels nor hydro power. BUT hydro power´s electricity can be used for making hydrogen, that is a fact.
lithium ion batteries can explode when overstrained, maybe consider something else like liquid metal (have fewer passengers). at least jetfuel burns somewhat slow and there are techniques to slow fire spreading in extraordinary circumstances. the lithium ion reactions would be much more violent
Lithium batteries are heavy, terrible choice for planes.
Amazing video and fantastic information, congratulations
"in anticipation of breakthrough battery technology"... oh that's the part where the magic comes in?
This video is absolutely put together with great info!
Thanks Robert. Appreciate that from a pilot.
These hybrid units are interesting. Especially because APU’s are already generating high electric power in some planes. The 787 has bleed-less tech meaning the APU generally starts the main engines with electric power.
Just discovered this channel and this video earned instant subscribe.

Brilliant presentation!

Certainly encouraging developments.
Well done also to the narrator, for a super slick narration.
im the narrator, writer, filmer, janitor, and also the guy in the plane. 😁
just saw your comment on lemmino's song, now I'm addicted, thank you :)
Yes, noise complaints were the Concorde‘s Achilles heel, but it was more the sonic booms the plane kept emitting and not so much the engines.
Well produced. Don’t forget the accessory power necessary to de-ice leading edges and pressurize cabins.
Haven't seen a single delta wing design. Seems like you'd want all the lift you can get. And the big surface area of a delta wing would allow you to have solar panels on it for inflight power regeneration. Probably not much anything that drops battery weight and can pay for itself in power generation is worth it.
@@rexmann1984 50 acre delta wing AREA will provide enough solar energy to fly half a mile 4 PASSENGERS LOL
@@crotononhudson7309 don't go putting logic in this conversation. Science is the most dangerous greenhouse gas.

How about boots that are ginormous and flying through major weather on the regular plus its simply more cold at high altitude.

Brilliant!
No one ever said an electric plane was impossible. They said a commercially viable cargo/passenger carrier is impossible. And it is.
It's not only an issue of finding enough power for the motors but also, those battery packs can handle only so many recharge cycles before they need to be replaced. Unless we have some huge advancements in motors and/or battery technology, I can't see electric planes being the norm anytime soon or at least, not anytime in my lifetime!
Something I forgot to mention, and something known to people in the aircraft industry, is that every aircraft engine needs a complete overhaul or replacement after a certain number of hours, and this is very expensive. So far the commercially available electric training aircraft use for flying lessons have batteries that last twice as long as the engines, and cost about the same or less as replacing or overhauling engines, so save the flight training companies a lot of money.
My idea is to keep the plane tethered to a power source right up until rotate which takes most of the energy. When it reaches a certain altitude the tether is disconnected.
draw me a picture 😁
@@ElectricFuture All EFV would be going down the runway with a self powered direct electrical connection vehicle joined with a quick release mechanism that releases the plane and provides power to the plane for as long as it can. At the end of the runway the DECV retracts its connection arm so it can deflect into an off runway small tunnel to prevent collision at the end of the runway.
Basically little electric engines in the wheels, with WiFi electricity from the takeoff "road" (not mother tongue) to speed up and gain takeoff speed?
@@ElectricFuture I gather he means an electric catapult.
Wow, great video. Thank you.
There is a sequence of events that need to take place;
Steam engine->steam turbine
Gasoline engine->jet engine
Electric motor->some sort of jet created by electricity, still waiting.......
Captain: "were out of baterry ! were going down ! Start the recharge!"...24 hours later
great video, great commentary and content :)
Awesome video. Deserves way more views.
consider some of the wilder possibilities this could open up. The tiny living movement also spawned liveaboard sailboats, and some of those are even going to electric drives that can generate power when under sail. It also spawned van life and all the different power options mentioned here for that too.
Now imagine one of those solar electric flying wings that is also designed to be a small apartment and amphibious. There's actually so many different ways it could go, maybe have wings that can fold back so it can be driven on the highway like a pickup truck towing a camper? However you want to design it, Flying life might become the new thing. Could even have a smart cockpit that would be a traditional cockpit for backup, but a smarter auto-pilot and with things like heads up AR displays to show various air-spaces and info about them, like what channel to contact that ATC for. Doing that might even make flying safer and make getting a licence easier. And how much more efficiant will something like starlink be when you're up at crusing altitude?
This was super interesting! Thank you!
