Question

Unlike nuclear fission, which involves dangerous radioisotopes, nuclear fusion involves what two harmless elements?

Answer 1

hydrogen and helium

The use of nuclear fusion for energy has several pros. Unlike nuclear fission, which involves dangerous radioisotopes, nuclear fusion involves hydrogen and helium. These elements are harmless. Hydrogen is also very plentiful. There is a huge amount of hydrogen in ocean water. The hydrogen in just a gallon of water could produce as much energy by nuclear fusion as burning 1,140 liters  300 gallons  of gasoline! The hydrogen in the oceans would generate enough energy to supply all the worlds people for a very long time.
