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.
Nearly all of our existing power sources are generators which use a heat cycle. This includes our coal, oil, and gas fired utilities, our automobiles, trucks, and trains, and even our nuclear fission utility power plants.
We have never succeeded in slowing down our nuclear fusion reactors.
We need the kind of leadership exemplified by President Kennedy to just do it! But we must do it as good stewards, aggressively exerting control over the moon. We can best do this by going there.
History has repeatedly shown that when a new method or material becomes available, new uses for it arise.
