Contrast this with his novel designs for the Space Shuttle, which would look like a 747, carry as many passengers as the 747, but have its jets on top of the elevators and carry three space-capable F-35 fighter jets. Like his triangular space station, which would be half the size of earth, all of these vehicles would be solar powered and capable of hyperspace. If fact, a single photon would suffice to charge all of them for 50 years, generating food, oxygen and materials. And one more thing: the space station would carry about 10,000 people and have a billion rooms, separated from each other by a mile of open space. Passengers/inhabitants could choose between gravity and gravity-free modes. They would have controls for adjusting gravitational pull. And don't forget the fleet of space-capable F-35's on the space station itself, 1000 in all, each armed with lasers powerful enough to destroy Mars (which would serve as good defense against asteroids and meteor showers). Force-fields surrounding each F-35 and an arsenal of special rockets would defend it against flame-attacks.
An array of probes could be deployed at any time to explore meteors, asteroids, planets, etc., and retrieve whatever they find. Any life they would encounter they could assess for possible coexistence with people. Naturally, the probes would also assess all environments for human habitability.
