Look up Thorium reactor. In the late 60’s at Oak Ridge they operated a thorium reactor successfully. It is much safer than uranium but in 1973 our government decided to go with uranium. Thorium reactors are safer to operate and generate electricity well.
Fissile fuel is still the most efficient and viable for transportation. Wind and solar are Chinese boondoggles. They destroy our environment, land and electricity transport on meager production that is largely unproductive a lot of the year. Their maintenance far out weighs any benefits. They serve to enrich China and drain our wealth.
