Helen Strong Take the tube to New York

Dream it. Do it. Why stop at New York. Time to open a whold new global metro.

Doug Vining A tube by any other name would be as cool

We published a MindBullet about this concept over a year ago. Now that Elon Musk is getting involved, calling it the Hyperloop, it's getting a lot more attention.

As we like to say, ideas get more powerful when they are shared, and those who say it can't be done should not interrupt those who are busy doing it!

Doug Vining Hyping the Hyperloop

My favourite technopreneur Elon Musk has revealed his 'alpha' design for the Hyperloop and it's remarkably similar to the SpaceTube concept we published in this MindBullet more than a year ago.

We borrowed heavily from ET3, but one critical difference with our fictitious SpaceTube was the use of a partial vacuum, which Elon has also 'adopted'. But where we imagined a maglev pod coasting along in a near vacuum, Elon has dismissed maglev as too expensive, and opted for a 'rail gun' accelerator, and an air cushion provided by a compressor to elevate the pod above the track. The idea of coasting along the tube, once the target speed has been reached, remains, which is key to the low-energy requirement of the concept.

As Elon has continually stressed, this is a concept design and open to contributions and improvement. Perhaps the ultimate implementation will prove to be even more radical and affordable.

But for Elon Musk, the Hyperloop is already a success. The publicity surrounding it has cemented his reputation as an innovator, and given a nice boost to the Tesla stock price. As someone who watched with bated breath as the first SpaceX launch went up in flames, and Tesla almost went bankrupt, all I can say is: "Well done, ...

Doug Vining Hypersonic airliners

Richard Branson's idea for hypersonic travel in the future is certainly audacious:

"We will be producing supersonic planes which will go far, far faster than Concordes," he said of the British Airways Concorde aircraft, which was able to go from London to New York in three hours but was retired in 2003 because it was no longer profitable.

When asked what his aircraft could potentially do, Branson said, "If we get it right, New York to Tokyo could be less than an hour. You could be traveling at 19,000 miles an hour orbitally."

But it's one thing to send three or four people to the moon or up to seven to the Space Station. Even sending a dozen passengers on a sub-orbital flip on Virgin Galactic will soon be standard practice. It's quite another challenge entirely to blast off with hundreds of passengers into low-altitude space, and descend again safely on the other side of the planet. It's technically doable, but the economics of the exercise will likely keep it just a dream for many more decades.
