Vacuum tube travel, the future of travel

Vacuum tube travel, the future of travel

(2:27) The next stage before teleportation. Vacuum tube travel is faster, safer, uses less energy and, believe it or not, cheaper than high-speed rail. Designers of ET3 (Evacuated Tube Transport) claim systems can be built for 1/10th the cost of high speed rail, or 1/4th the cost of a motorway. It begs the question - why is the UK wasting time and money on HS2, the high speed rail between London and the Midlands? More about ET3 and how it weighs up against rail.

Hmm, what happens if there's a crack or something and the vacuum in the tube is no longer there...ceases to work and everyone's stranded? Or if it doesn't stop, perhaps it continues at the 4,000mph or whatever they said straight out of the tube killing everyone. The idea is good, but needs to be made accident/external terrorist proof

Latest comment: A Airplane Isn't Terrorist proof or accident proof but i don't stop people from getting on it. If people get on airplanes , they would get in anything, believe me ... People go to amusement parks and get on extreme rides every day... Come on ! The only problem i see that can't be worked out is a bathroom emergency . Maybe travel diapers...

I'm no expert but I'm guessing that if the vacuum was lost, you'd still have the mag-lev effect but you'd slow down because of the air resistance. I believe the Japanese have just tested a mag-lev train at 500 mph. If the capsule 'breaks down' in the middle of nowhere, then that's no different from a train breaking down in the middle of nowhere today. Emergency services would come to the rescue but would only have to deal with 6 people rather than a full train's worth. You don't get the problem of 'deer or fallen trees on the tracks', and the system is imune to weather conditions. About terrorist attacks, we have the same problem today with railways and oil pipelines, and vacuum tubes could well be easier to monitor. It's a brilliant idea.

Would be much better if they shut up and just made out with each other.

The most retarded presentation I have yet seen. Seriously if you need ideas presented in this fashion you should have your arse surgically grafted in place of your head. a bit like these girls.

You lot have missed the point. This is a good idea and they are trying to get it into the consciousness of the average American. They tend to be pretty thick and need bright colours and pretty, screamy girls.

A pair of high-pitched, gabbling girls and a series of images for people with attention span deficit. If someone wants to put an idea over, use grown ups and grown up methods. That just made my head hurt.

It's a good idea in theory but there will be huge practical issues. Firstly maintenance, in the UK alone, the water board loses 3.3m litres per day through leaks and cracks according to the Independent, that's just on our small island, imagine a worldwide system. One crack would mean huge delays and expense as the vacuum wouldn't be maintained. Secondly safety and security, if a passenger suffers a cardiac arrest, how can you get an emergency vehicle to them or get them out of the tube quickly and efficiently? Given that the vacuum has to be replaced with air in order to propel the capsule, what happens to any fires started in the tunnel as a massive rush of oxygen flows through it? The presentation seems to be aimed at children and seems to have no science or figures behind it which politicians, investors or inventors would really need before even giving this a serious thought.

First, the quick time you will get to your destination gets rid of any need for emergency vehicles to get to you. Second, who said anything about pumping oxygen in the tube? Why not nitrogen?

I'm not sure you understand how this is supposed to work. The capsules are magnetically levitated meaning there is no friction from wheels on tracks. The Shanghai maglev train has been in commercial operation since 2004, and is the world's first high speed magnetic levitation system. What limits the speed of maglev trains is air resistance, which is where the vacuum tubes come in. And your point about the water board, leakages are due to parts of the system built in the days of Queen Victoria.
