When it comes to top candidates, I think the cube – shaped device of magnetic coils by Bussard and his team showed great promise. It was already producing something like 20,000 times more fusion reactions than the best Farnsworth fusor device. But then the Pentagon killed funding just as it was starting to show great promise. This is typical of government and your taxpayer dollars at work …. too much stop and go funding instead of anything ever being consistent.
The Bussard device is called the Polywell, and the Navy is funding it fairly heavily. Check out http://nextbigfuture.com/2009/09/iec-bussard-fusion-has-gotten-8-million.html and http://www.talk-polywell.org/bb/index.php .
