Focus Fusion is a specific aneutronic method for producing electricity from plasma fusion of a boron compound and hydrogen, by generating a metastable toroidal plasma between a central post electrode and several surrounding post electrodes, from a large ultracapacitor voltage source.
The plasma so generated automatically collapses in such a fashion as to generate charged particles that exit through a coil that converts them directly to electricity, with no moving parts. Incidental x-rays are also converted to electricity using a multilayer wrap of several elements to cover the wide range of x-ray frequencies generated.
Emission of neutrons is very low, thus overcoming one of the most important objections to such processes, and the process proceeds by repeated impulses, occurring the low kilocycle range.
The process is much cheaper than tokamak to build and has recently (October 2009) achieved actual fusion and produced energy.
