This was never replicated, and not very well recorded. Cough...fake...cough.

Sorry I was thinking of Cold Fusion, which cannot be replicated.

Here is some info: http://encarta.msn.com/encyclopedia_761558960_4/Nuclear_Energy.html

Nuclear fusion was first achieved on earth in the early 1930s by bombarding a target containing deuterium, the mass-2 isotope of hydrogen, with high-energy deuterons in a cyclotron (see Particle Accelerators). To accelerate the deuteron beam a great deal of energy is required, most of which appeared as heat in the target. As a result, no net useful energy was produced. In the 1950s the first large-scale but uncontrolled release of fusion energy was demonstrated in the tests of thermonuclear weapons by the United States, the USSR, the United Kingdom, and France. This was such a brief and uncontrolled release that it could not be used for the production of electric power.
