Why? Space Mission Analysis For any space mission, there are a few basic questions that must be answered: What is the destination? To convert the reactor heat into electricity, thermoelectric or thermionic devices could be used, but these have low efficiencies and low power to weight ratios.

After all, he was rather reclusive, all of his work was published in German and his brief moment in the spotlight was in 1957 when he proposed an odd propulsion system that could easily achieve relativistic speeds. A spacecraft powered by this hyperdrive would get us from Earth to Mars in just a few hours and make exploring our immediate stellar neighborhood possible within our lifetimes.
Sound too good to be true? Originally, Heim was trying to reconcile quantum mechanics with general relativity and created a universe with six dimensions in the formulas he used. How much energy would it take? While Drcher’s designs might not work and Heim’s ideas might be off in some critical places, this work can give us some interesting new directions in which to push the physics of warp drives.
