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.

Rocket scientists agree that we have about reached the limit of our ability to travel in space using chemical rockets. To achieve anything near the speed of light we will need a new energy source and a new propellant. Nuclear fission is not an option.

Our present nuclear fusion reactors are classified by the methods used to support the nuclear fusion reaction, which takes place at a temperature much hotter than the surface of the Sun.

History has repeatedly shown that when a new method or material becomes available, new uses for it arise.

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.

When you buy a gallon of gas, over 60 percent of the energy you pay for goes out the radiator in the form of waste heat? That's why you have a radiator in your car in the first place.
