So... basically- if we get better material, better fuel, better engines, better design and better investment- WE HAVE AN IDEA!
we need asteroid mining
phajthoj indeed. And we will, within the decade, thanks to spacex
Asteroid mining could never be profitable.
it will when the time we find a more efficient way for space travel not using rocket fuels
You mean *if.*
Would be better in metric!
Dont forget the space-x bfr project...
It's all fun and games till grandma climbs in a rocket and her bones explode when they hit mach one.
SSmotzer true true
LMAO!!!!
Scuse me, I'm French and this video is my homework (do a resume)but I did not understand, can I have tradition or resume please?
Use metric system to explain 🙄
Please stop using imperial system. Even as an American I want the metric for scientific videos
Although this is a british channel I imagine many of the viewers are from other countries, almost all of which use metric always.
Why should they use metric? It’s a British made program, we use the imperial system.
Why don't use both? Besides he used metric units in some parts of the video, which makes it even more confusing.
oomegalinux
In the UK they use feet and inches to describe a persons height, stone to describe a persons weight, and miles to describe long distance. They tend to use either feet or metres to describe shorter distances. With it being a program made by the BBC, I don’t understand why they would use a measurement system not used by British people?
Wow, even more confusing than I anticipated! The "stone" is completely new to me.
I have no desire to be fired at 700 mph in a vacuum tube (Hyperloop). And what if there is an accident and the passengers need rescuing?
There won't be much left to rescue. Probably take a bucket and mop to clean them up
There is no probable way for hyper loop to functionally work. Maintaining a vacuum that large is highly questionable and the time to pull it down would cancel any time saved.
everett higginbotham Well...ol' Musky boy has pulled off quite a few feats before, I'd wager that he'll get the better of us again...😄
They don't need to depressurize the tunnel before every trip. Passengers can get on board through an airlock, simple enough. It's also the easiest part of a large particle collider, and those are superficially similar.
No, the problem is Musk wants to put the depressurized metal tube out on the desert where it would grow by miles during the day and shrink by miles at night, causing the metal to bend and warp, which would cause it to implode at a fraction of the vacuum Musk wants.
No, I watched the episode of Mythbusters where they depressurized a steel oil tanker train car and it imploded.
I smell scientific illiteracy; ThunderF00t isn't the only person who has pointed out all the flaws of the Hyperloop system- you're also ignoring the fact that Musk is not running the project anymore, he just dreamed it up and then left it to a bunch of school kids to try and figure out how to make it work. If that doesn't set off alarm bells, nothing will- the issues with maintaining the system and keeping it secure cannot simply be dismissed.
Use metric, bbc as the majority of the world!
What if we all had jet packs powered by mentos and diet coke?
The future is now
Use metric, also ''highspeed'' rail in the UK is a joke
When I heard Hyper loop, my Thunderfoot started tickeling.
?
put solar panels inside the hyper loop with LEDs made out of air carbon
Solar fricking roadways.
Thunderfoot? That quack? Meh.
I'd rather listen to actual scientists and engineers thanks.
KuraIthys like who? Give me a list of Scientists that said that Hyperloop or the solar roadway can be done. And FYI Thunderf00t is one of the best Scientist on CZcams.
00:59 what they said to me when the train slowed down to 250 kph when we got to england was that the tracks were not good enough to sustain the normal 300 kph speeds it does in France and Belgium.
great video bro
3:55 doubling up the train tracks can be avoided if using a docking system that utilizes air craft.
Such a tease. That scramjet engine aircraft really peeked my interest ._.
love the oh so quiet countryside train station. so typical. You can feel the depressive atmosphere.
You forget to mention Spacex BFR and it's plans to provide human travel anywhere on the globe in less than a hour! from all of the mentioned flying technologies BFR is a real plan witch have already started it's development..
BFR is not suitable for that. Technical issues aside, what do you think would happen if you want let people on board of (edit)a vehicle fuelled with(/edit) 1,000,000 kg of explosives?
For comparison: your garden-variety air-plane (ex. A320) carries a maximum of about 27,000 kg of fuel at a maximum TOW of about 78 tons and a top speed of about Mach 0.8. In the autumn of 2001 the world could witness what this means in the hands of the wrong people. A rocket with a TOW of 1,350 tons and a at supersonic speed would be about 6000 times as destructive (at Mach 3.5) from mass and speed alone. Even just the fuel exploding would make for one hell of a bomb.
Are you really that naive to think that any sane person would allow commercial usage of such system on a scale comparable to commercial aircraft? Sure, a selected few might be able to buy tickets for a sub-orbital adventure ride around the globe at some point. But large scale aerial transport?
i still think even if it will never come true, the creativity of it is amazing, this idea is bizarre, but that's what makes it so special, it challenges human imagination, the same with the airplane and every other invention. it's about challenging ourselves and our imagination. the ideas is good if people will love the idea but the problems you described will be the reason for it to never happen, then maybe one day somebody will modify the idea to take out those risks because the Benefits are clear. But thanks for the answer! Keep up with updating us with the newest technologies!
The low earth orbit (LEO) satellites can reach up a speed of 27600 km/hr (at 250 km). By launching a rocket that can reach up to that speeds we can attach a plane to a similar satellite and can complete the ride around the globe in less than 90 minutes. An example of LEO satellite is International Space Station.
Yeah, but in order to commercially utilize that kinda system would require rockets to accelerate so slow it would be faster to just take a normal airliner around the world.
@@SSmotzer Not even true what the hell, if you accelerated that slow you wouldn’t reach space
@@GrapeFlavoredAntifreeze Exactly.
Good thing neither actually happened.
@@SSmotzer What are you talking about
@@GrapeFlavoredAntifreeze Have you seen the Hyperloop? It's an Uber based subway tunnel with RGB lighting, cause surprise surprise, you can't create a vacuum on a large enough scale to make vacuum based transportation possible. Plus with Elon developing a hatred of trains in the past couple years, I doubt Elon is gonna be heading any public transportation ventures. Not to mention him allowing Space X to go bankrupt so he could sell it as a tax write off.
I like the hyperloop idea, but if that would take 50 mins to get from London to Edinburgh, that's the same amount of time that it takes to fly from London to Edinburgh.
Yeah, it's a good idea, so good in fact scientists have been working on vacuum tubes for over 50 years, and the best thing to come from that are those transport tubes at banks that shoot canisters around.
Any large scale vacuum has ended in disaster, except for NASA's chamber which is underground with a mountain of concrete poured over it to prevent it from imploding.
That Soundtrack or Background Music?
UK has no real high speed trains, only the Eurostar to France/Belgium. The rest of the EU has way better high speed trains.Btw switch to metric, please
In America, our trains sometimes reach speeds of 50mph! Oh yeah we zoomin'!
He's talking about the tilting trains that can actually go pretty quick on our very bendy tracks....
I laughed at that. “High Speed trains blasting through the British countryside at 140mph” ooo woo super rapid haha. TGV does 200mph pretty regularly, and to be fair High Speed one gets to 186mph.
fascinating!
A british program, about cross-continental suborbital flight, and NOT ONE WORD about Skylon?
Fun outlook, however there is one other factor which is sadly overlooked. A high top speed is all nice and well, but in order to keep accelerations at comfortable levels, the portion of the journey spent on acceleration and deceleration becomes ever larger for higher top speeds, having quite an impact on the quoted travel times.
Good video, what about Skylon? Skylon has solved many of the problems of oxygen air intake at very high speeds. they have a working prototype engine.
Finally, a video that makes up for the last few disastrous ones from BBC Earth Lab.
It doesn’t lol. This is all BS.
There has been no scientific research before making this video
The tunnel through the earth brings to mind the movie "The Core". B grade fun. What kind of energy would need to be expended to get the train climbing back up from the core?
If you accelerate every single particle surrounding a craft, away from the craft there is nothing to interact with to slow you down, you would have to rely on your initial thrust because there would be nothing to interact with....
You might as well add teleportation to this list of hair-brained ideas that will likely never happen.
so no mention of point to point travel with BFR?
I believe you should have mentioned the BFR (big falcon rocket). To any place around the world in about 30 min seems like the concepts you showed.
BFR!!
No one is using rockets for commercial transportation for a reason. It takes years to train a human in peak physical condition to withstand the g forces of a rocket. There is no way grandma will be climbing into a rocket, she would turn into goo.
+SSmotzer So leave grandma home
That's not the point. The point is astronauts and pilots need to train for years, be in peak physical conditions, and wear specialized gear to withstand the g-forces of a rocket.
The is no viable way for rockets to be commercially viable as a transport system. People have been trying for 50 years to find commercial uses for rockets, and they have all failed, not because they didn't have the technology, but because the human body sucks.
+SSmotzer Dude...he is even talking about gravity train
Yeah, and those things can go way faster than they normally do. Because if they went from 0 to top speed the passengers would all die.
It's not about how faster we can make something go. It's how fast we can make the human body accelerate before it breaks.
No mention of the BFG?
You forgot the BFR ;)
Interesting you mentioned speed in mph, but distance in kilometers.
ok so if you tunnle through the earth and use gravity to drive the train through whats going to pull it out the other side because half way through your no longer falling your climbing
I've got an idea. Turtles. I've seen it, it's amazing!
I've got a solution: don't travel! If the future is capable of producing these kind of machines it will surely be capable of inventing a society where one doesn't have to go places in person.
Disagree about us not having the materials for hypersonic flight. We have NASA. And space shuttle reentering the atmosphere are superheated and it's traveling far faster than the speed of sound. Now we just have to mass produce those metals and fabrics.
can we not make a cabin that is stuck with a tube on a kind of 2 engines that goes through the space and pushes the capsule where you can connect to the capsule with a kind of helicopter
teleportation is faster i guess
No, you can get fast but not that fast. The ISS takes about 90 minutes to orbit. Go 2x as fast and you are squished into the ceiling at 3g. This takes 23 minutes to get halfway round the world. Except you need to get up to speed and down again. Making the time more like 40 minutes.
Such a technical thing we’re talking about and everyone is complains about the switching to metric 😂
What about spacex BFR?
How about BFR?
What about the SpaceX BFR?
In the 1969 TV show "Land of the Giants" the Spindrift craft flew from London to LA in 30 minutes. Nothing new under the sun.
nah hyper loop is not going to be commercial. Too expensive to keep up a vacuum that large.
hyperloop is just a wasted of money the idea of a hyperloop is 100 years old and its still an idea
The BBC spent more on that rocket CG than it would have cost to just buy a firecracker.
XB 1 isn't a concept, it's in prototype production
You forgot the BFR
BFR is the thibg you did not mention
Too bad most of us will be as old as dirt or dead before this happens... Man I wish I could have experienced these things when I was young.
So basically, we need teleporters.
Can not waiting for ...
I wonder if these long tunnel people ever heard of Plate tectonics?
Plate tectonics isn't that much of an issue - the plates move at about 2 cm per year, which would be by far the smallest problems with the whole gravity train idea.
What about comercial rocket travel
Why transport your body to another destination, when your mind can be transported in seconds. Which can be done today.
Just hook yourself to a machine and connect to a life size unoccupied android that already stationed half way round the world. Film -Surrogates
The answer to the ultimate question of life, the universe and everything is 42
william ambrose Well, earth has been built to calculate the true question to 42, so it does make sense.
Your forgot the highest profile solutions. Reaction Engines SABRE engine (used for Skylon and other purposes), and SpaceX' BFR Rocket (point to point anywhere in 30mins).
Yeah, the problem is humans aren't built to withstand sonic speeds. So the whole 30 minutes to anywhere is out the window because accelerating to that kind of speed would cause grandma's bones and organs to turn into jello, and grandpa would just explode.
Musk said like around 3G maximum load for passengers on BFR rocket, and then zero G for most of the journey. He usually know what he's talking about. It certainly has some complications as a mass transport system but, its certainly worth investigating.
So if grandma gets in the rocket, and she weighs around 200 lbs, she would have to withstand nearly 400-600 lbs on her body? Yeah, I don't think so.
Astronauts and air force pilots have to train and wear specialized gear just to withstand 3Gs, there's no way something that dangerous would be allowed to be commercially used.
This isn't a matter if we can or can't do it. We have the tech now, we've had the tech for 50 years. It's all just a matter of safety, and there is no way to get something to sonic speeds without it accelerating to that speed first, and that is where the danger is. Go too fast and grandma explodes, go to slow and it would be easier and faster to just drive or take a plane, or train.
So like, trains that suffocate you?
Space-elevator + gliding plane
Just make a wormhole, and travel anywhere in just a second 😁
Hyperloop has been debunked. The energy required to create the void and the problems with the tunnel structure itself can be used in other ways
The v o i d
Fun fact. To travel "half way around the world" in 9 minutes, you would have to be traveling at 2222 km/minute (37.0 km/s).
At that point your bones would be liquefied.
Only if you accelerated really aggressively, otherwise you would be fine. I think the ISS is traveling at a relative velocity of 27500 km/h.
dude, you would experience 21.6g of acceleration, just to stick to the curvature of the earth.. (ok, -1 for normal gravity, still 20.6g)
And that is totally discounting speeding up to the speed needed, or slowing down. that is just for hanging on!
Marvin Kitfox No, no you don't.
I am not sure if the figure is right but if I am understanding things correctly do you mean you would have to accelerate downwards towards earths center of gravity in order to counter-act the altitude gain from moving so fast? Just interested =p
SpaceX BFR should of been mentioned.
Just dig tubes through the earth^^
by the end of the 1700s in the US, you could travel from the east coast to the west in about 6 months by wagon. by the end of the 1800s, that was reduced to 6 days by train. at the end of the 1900s it was reduced again down to 6 hours by plane. I am guessing that by the end of this century we will be able to travel from one end of the country to the other in only a few minutes.
but I am pretty sure no one alive today will be able to tell. if you are born today you will be almost 82 years old by the end of this century.
Sorry to blow the video... but you forgot the TR-3b and the TR6... mach 9 or more?
BFR may be...
I could travel the world within seconds. But takes hours to travel this world🌍. 😄
Sleeves and subspace communications.
And how much? I'll pay money to get to where I need to go at 600mph.
Mentions Elon Musks Hyperloop, but when talking about aircraft, fails to talk about Space Xs BFR
No BFR ?? lol
You forgot a big one! SpaceX is considering using their BFR as intercontinental transport. It would be as fast or faster than many of the examples in this video. Link: www.space.com/38314-elon-musk-spacex-mars-rocket-earth-travel.html
I never keep my devices in airplane mode.
Agree with many others, please use metric as the videos are scientific
Well, a lot of it is a matter of cost (and a bit of politics) at the end of the day.
We had concorde in the 70's. There is basically almost nothing stopping us from taking that existing design and building 20,000 of them.
But, people object to the sonic booms, and the fuel costs are huge.
That is however, well established, proven technology, and it'd get you basically anywhere in the world in under 10 hours.
This we know we can do.
But can we improve on it any?
Faster? Cheaper? Less Noisy?
Most likely we can, but still...
people should make hover tanks
When you dont mention the BFR :(
Because it's complete and utter BS in that context.
I disagree, the BFR's plan is to be able to shuttle people from any two major cities in less than an hour, it seems perfectly applicable here.
Let me put it this way: commercial aviation is a hundred years old now. We know the ins and outs of how to transport people from one city to another by means of flying subsonic and supersonic aircraft. It turned out that supersonic aircraft aren't profitable using current technology (case in point: Concorde and TU-144). Major breakthroughs in both material science as well as supersonic engines in terms of economic feasibility and environmental impact (especially noise!) are needed.
Other than that there's an existing infrastructure surrounding the whole business. So far so good.
Rocketry is as old as commercial aviation and manned space flight is about 45 years behind. Again, we know the ins and outs of (manned) space flight using rockets. It's been done on a regular basis for more than 50 years. The idea of using rockets for commercial passenger services isn't new either. It hasn't been implemented for the same reasons Concorde and TU-144 failed: it's simply not economical at all. In addition to that, rockets present a whole new level of security concerns. If you thought that 9/11 was bad - think of what a rocket with 37 times as much fuel at 3 times the speed and 17 times the mass could do (hint: physics says it's about 6000 times the amount of energy). I'm not going to mention the noise levels such a rocket produces. I will ignore the ludicrous idea of subjecting your average Joe to g-forces beyond 3g for an extended period of time. I also don't mention the idea that SpaceX wants to fuel their rockets only after the passengers are on board [1], which would take considerably longer than the flight itself.
All this ignores weather, additional infrastructure cost and maintenance procedures. Note that I'm not saying it couldn't be done. I'm saying it's BS from an economical, ecological, and safety point of view.
I am curious to hear why you would still think that using a rocket to ferry people from city to city is a perfectly sensible idea.

half the fun was the journey, let's return to airships or flying boats with stop overs.
So what you never herd of SpaceX and the BFR or what
teleportation boi you missed teleportation
0:45 lol you made a mistake. With an object that is moving on wheels, the friction of the road doesn't slow it down. It's the friction between the parts inside the car and air resistance alone. Come on, bbc.
You didn't mentioned Elon Musk's BFR, which he plans to use for Earth based passenger travel.
No
you missed elon musk's rocket taxi a rocket that shoots into space at an angle and lands back on earth in another location on the globe
You mean like the Red Dragon idea, or the plan to send tourists around the Moon by the end of this year? Both ideas were cancelled because not everything Jesus Musk says is actually doable. Most things are, but not all.
does anyone watch the footage before you post? like do you not see the white text over the overexposed white background and think; hmm maybe not
great video ! Please switch to metric
Rooftop Adrenaline
Why? It’s a British program, that’s the units we use.
You did not read his comment did you. "Please switch to metric". Yes he is right, it should have been in metric.
Zanzubaa1
And you didn’t read my comment right. I’m asking why they should have used metric?
Zanzubaa1 NaCl
Oh right, I misunderstood then but to answer the question he probably should have used both. We only really use miles an hour in any official capacity when talking about cars and road speeds. For science subjects (such as this video), we use meters a second. It's a convoluted mess is what it is. We would have totally gone metric but I can only guess they did not because of the cost, same reason we are right hand drive still.
Feb 9? You haven't heard Elon's plan on using rockets?
*aeroplane mode
you people seem to be forgetting acceleration and deceleration times in your travel time calculations... among other stuff.
bleh, this wasn't a good video.
Unless the Antipode could accelerate to and decelerate from its maximum speed instantly it could not travel the 3500 miles from London to New York in 11 minutes. A more reasonable estimate would be 19 minutes allowing for a maximum 2g acceleration force on the passengers though I wouldn't call experiencing 2g for 15 minutes of a 19 minute flight "luxury". Keep in mind that astronauts train for years and wear pressure suits to handle the 3g loads experienced in a manned space launch.
Oh and MACH 25 is considerably more than 12,000mph. It is 19,030mph.
Spaceliner? Seriously? This system would face all the same issues that the Space Shuttle had to deal with and that system was moth-balled largely for being too expensive to operate safely.
So many basic math and science errors in one simple video.
What about elon musks BFR
Yea, all they have to do is lower the explosion rate from 10% to .001% decreases the acceleration of the rocket to that of a commercial airliner to prevent anyone from dying from the g-forces rockets typically dish out, which causes trained professionals in peak human condition to pass out.
@@SSmotzer yea, sounds completely easy, doesn't it? Only a few hundred decades of hard work and attempting to break the basic laws of physics! Yea, totally practical!
@@t.3465 That is Elon Musk's MO isn't it? Promise something completely insane that goes against decades of scientific practice and then deliver something that only vaguely resembles what he promised.
@@SSmotzer exactly. I mean, I appreciate him changing the world for the better, with electric cars and reusable rockets, but there weren't many problems with physics or actual science, rather just with the economics and the interest people have in them. However, if you are gonna try to fly rockets around the world, you better put everybody in a serious G-suit and hand everyone 5 vomit bags, because the ride is gonna feel anything but consistent. Either, you're gonna feel like there's a bomb underneath you while taking off (which is partially true with rocket reliability ratings) or you're gonna feel sick by floating around in orbit for 40 minutes. I don't think people want to get on top of a controlled bomb and feel like they are a leaf in a hurricane whenever they just want to go on a honeymoon or visit family.
@@t.3465 Well he didn't change the world with electric cars. Tesla was already making electric cars before Elon bought the title of founder from Tesla. I guess Elon made electric cars a hot button issue and pushed other car manufacturers to increase production of their electric cars, but that's not exactly changing the world.
Not in a hyperloop no..
42 minutes))
All you need is a carbon fiber CVT. I'll take my cut in cash.
low key all the problems they just mentioned are already solved they just didnt put in enough research to fin information on it lmao
