Thanks, now i remember hearing about this. > Project Daedalus later proposed fusion explosives (deuterium or tritium pellets) detonated by electron beam inertial confinement. This is the same principle behind inertial confinement fusion. Theoretically, it could be scaled down to far smaller explosions, and require small shock absorbers. That's an interesting tidbit about the size. Also reminds me of the Deadalus spaceship from the stargate universe. But it sounds like politics is the only limit here, surely they can ammend the treaty to allow space-travel work under IAEA supervision.
