Nuclear fusion of light elements like hydrogen or helium would permit approaching the speed of light. It seems very attractive to refuel your space ships where the fuel is.

France generates a significant part of its energy requirements from fission reactors and these have achieved a perfect safety record. We build ours all differently.

Failure is a learning experience, and the guy who has never failed has never done anything.

There is more He-3 energy on the Moon than we have ever had in the form of fossil fuels on Earth. All we have to do is to go there and get it.
