[TH] Japanese Firm To Build Space Elevator

post #1 of 201

Quote:
The elevator is expected to be able to carry up to 30 people at a time, but don't expect to be able to hop on it spontaneously. Obayashi said that the elevator may be traveling at a speed of 200 km/h (124 MPH), which means that the a one-way trip will take about 180 hours or 7.5 days.

How cool is that? It would be way more efficient to use this elevator to exit the Earth's gravity, then launch shuttles that are already in space to the moon or mars or anywhere else.

So, how expensive is it to manufacture and deploy almost 120,000 miles of carbon nanotube cables in space, build a space station and develop an elevator that travels at 124 MPH? Obayashi said it has no idea, but they now have a project in place and "try" to make progress to make sure a space elevator "won't end just up as simply a dream."

How can you possibly "plan a project" without understanding the financial implications?

I mean, you have to start somewhere, but that seems mighty foolish to me.

Queue elevator music and uncomfortable moment of silence....for 7.5 days.

Edit: Oh, and question. What happens when they build this thing and there is another massive earthquake/tsunami? Will the elevator rip from the ground and float off into space?

I liked the design in Kishiro's manga.

They won't build it in Japan. Physically impossible, it's too far north. It would have to be closer to the equator. They'll probably pick a spot that's relatively safe from natural disasters and social upsets.

What the...96000km? The International Space station is only about 400km up or so. This is like a fourth of the way to the moon.

I think some one messed up a decimal point or two.

200 km/h sounds a bit low for this type of project. Ok perhaps first 20-30 km you want to good at that speed to keep the air friction low but after that you are basically free to go as fast as you like - depending on what amount of energy you have available.

It kind of sounds that these gys have really not tought out what they are doing. With the solar farm up at the orbit and them transferring power down to earth through that carbon cable the "shuttle" should not have exactly shortage of power.
