"From the Ted Talk by Bill Stone: Inside the world's deepest caves"

#### Unscramble the Blue Letters

If we're going to get that, and make that gas station possible, we have to figure out ways to move large volumes of payload through space. We can't do that right now. The way you normally bilud a seytsm right now is you have a tube stack that has to be launched from the ground, and resist all kinds of aodariyenmc focers. We have to beat that. We can do it because in sapce there are no aiecnmayodrs. We can go and use illtnaafbe systems for almost everything. This is an idea that, again, came out of Livermore back in 1989, with Dr. Lowell Wood's group. And we can extend that now to just about everything. Bob Bigelow currently has a test article in the orbit. We can go much further. We can build space tugs, orbiting platforms for holding cryogens and water. There's another thing. When you're coming back from the moon, you have to deal with orbital mechanics. It says you're minvog 10,000 feet per second faster than you really want to be to get back to your gas station.

#### Original Text

If we're going to get that, and make that gas station possible, we have to figure out ways to move large volumes of payload through space. We can't do that right now. The way you normally build a system right now is you have a tube stack that has to be launched from the ground, and resist all kinds of aerodynamic forces. We have to beat that. We can do it because in space there are no aerodynamics. We can go and use inflatable systems for almost everything. This is an idea that, again, came out of Livermore back in 1989, with Dr. Lowell Wood's group. And we can extend that now to just about everything. Bob Bigelow currently has a test article in the orbit. We can go much further. We can build space tugs, orbiting platforms for holding cryogens and water. There's another thing.
