SPACE: This Steam-Powered Spacecraft Could Travel the Solar System Forever.
- The genius of a steam-powered spacecraft is that it could harvest its fuel from the places it would visit. Water is everywhere in the Solar System; nearly every rock floating in space has some, and it wouldn’t be too difficult to harvest it with a spacecraft. Once harvested, the water would be heated into steam and ejected out the back as propellant.
