I invite you to take a new look at http://focusfusion.org/" [Broken] After a long search for funding, Eric Lerner and his team from LPP are really on the move now, constructing a new, most powerful DPF (Dense Plasma Focus) machine, exclusively devoted to fusion research, that should deliver a proof-of-concept for nothing less than break-even P-B11 fusion within as little as two years. Very little neutrons, no liquid helium, no radioactive or "unobtainium" fuels, no steam, no turbines. Just direct conversion of fusion energy to electricity and relatively little waste heat. Just making watts instead of rads and holding the promise of power plants in the tens-of-megawatts range that are small and safe enough to be operated in industrial and urbanized areas, where electricity is needed most. Furthermore, ships and even trains could benefit from such a fusion drive. Eric claims to have a solution for the problem that p-B11 fusion should emit more energy as X-ray bremsstrahlung than the reaction can ever produce, by applying a quantum physics principle that cools electrons significantly in the presence of a superstrong magnetic field (in the gigagauss range). This field, fortunately, generates itself in the course of a tiny plasmoid shrinking down and heating up towards fusion temperatures. As a result, the electrons in his plasma should remain much cooler than the ions, making the whole process energy-positive.
