Cold Fusion -- The Sun in a bottle
No other scientific endeavour has consumed so much talent, so much cash and so many years of sustained effort as the race to harness the power that makes the Sun shine. Billions of pounds, (and dollars, roubles and yen), more than four decades of research and the careers of thousands of physicists have been expended on the search for a nuclear reactor that will generate limitless power from the fusion of hydrogen atoms. Here's a little webpage that will give you a nice primer of information about cold fusion. Such that you will at least be conversant in the subject.
