What is the name of the nuclear fuel they are researching that doesn't cause meltdowns and is enviro-friendly?

Answer 1

Fusion reactor

Answer 2

Not sure if maybe you are asking about Fusion (and the ideal dream of Cold Fusion) which simulates the reactions in the sun of turning hydrogen into helium which releases energy.

Our current nuclear reactors use a process called Fission, where heavy radioactive elements (Uranium & Plutonium) are split into multiple lighter atoms (but still usually radioactive thus nuclear waste).

Fusion would be cleaner potentially because the heavy elements are avoided, however there would many of the intermediate steps would include light radioctive isotopes (deuterium & tritium).

To produce fussion like the sun does would require some sort of containment system because the reactions only happens at super high pressure and temperature - Although there are fussion reactors being built for research purposes that use such a technique, it is not yet practical to extract energy this way. Thus, the dream for a way to accomplish the fussion reaction at (or near) room temperature - This in theory could provide and unlimited cheap clean source of energy.

Answer 3

No. Both Fission and Fussion Cause great heat and lots of waste. However if you used hydrogen as fuel it would burn clean and be enviromentally friendly and we would never run out of it.

Answer 4

However,with regards to the previous poster,most of our hydrogen resrves are located in water,which require electrolysis to obtain,which reuqires electricity,which we obtain from fossil fuels. This extra process of electrolysis increases inefficiency of energy.
