Hyperloop: Billionaire Tech Mogul's New Idea Could Revolutionize Travel Forever

Can't wait to see what this actually uses! It seems the forumites are trying to limit Musk's idea to their way of thinking. Just imagine the future we could have if this idea succeeds!:D

Acceleration and deceleration can be smooth and gradual.

The centripetal forces also won't be a problem with large radius turns.
Someone with a mass of 100kg moving at 900 MPH (402 meters/second) would experience 1.64G's in a turn with a radius of 10km.

Imagine the tube breaks from some freak accident like a plane crashing into it. Then you have people being launched into the air at 1500km/h :D
 
I love creative thinkers, the ability to think beyond the current or minimum of 2 decades is not a gift many have.

We have to dream, I have always believed that almost anything is possible. If we can conceive of it, we can make it happen.

From the candle to the LED.
From the horse to the maglev and the plane.
From snail mail to instant cloud computing.

Our global population is not going to stop expanding, and our sciences, engineering and innovations will keep rolling along, regardless of the fact the majority of the global population are consumers and not contributors to ideas and innovation.

Very every 100 million dullards there's a genius somewhere lol - thank goodness :)
 
He's perfected the Great Glass Elevator

Somehow the name 'Hyperloop' makes me think this has something to do with traveling in low earth orbit (and thats where they build these loops and tubes).
Bu then he must also have an idea to get to LEO fairly cheaply (without propulsion), maybe a space elevator or maglev in less time or same time it takes the shuttle

???

He says there is no need for rails... To pump large amounts of air out of a tube that long would be impractical if not impossible. Also it sounds like it is personal transport to some extent (leaves when you arrive) but mass transit since it is to replace a train. The speeds seem ambitious too. Would that speed not make it the fastest thing on land? At that speed it would actually create a sonic boom. Again not practical.

The fact that it is a "loop" makes me think that trains only run in one direction ie clockwise in a giant "ring." The best thing I can think of is a maglev type system that is suspended rather than traditional train on rail and I assume the tunnel will be there to create some sort of drag minimising/ air boosting effect. Perhaps an aerodynamic pod uses the tunnel to create a sort of "scram" jet.

You're right. No need for rails is MagLev technology. Pumping the air out of the the tube is what Evacuated Tube Transportation is all about. It's not impractical, you only do it once, there are airlocks at each terminal station. In a vacuum there cannot be sonic booms.

Read US Patent 6374746. It reads like Sci-Fi but the science is sound. It sounds sound.

There are many similar patents, so I hope Elon Musk found a way to do it cheaper.

Imagine that little compartment at the back of the capsule contains a parachute...:)

It isn't a true vacuum. It is a low air pressure tube from my understanding. If they manage to get the air pressure to half an atmosphere there will still be a sonic boom. But in order to ensure the system maintains that air pressure they will have to build extremely strong tubes to withstand the force of the air pressure difference externally + the shockwaves that would be built up from going that fast.

I have heard Scientist and even NASA state before that using something like a centrifugal force, there should be a way that they can cancel out or even dampen the sonic boom in some way. Maybe he got an solution to do this.
