Fu-sion! Fu-sion! :)

''Low-Budget Fusion Reactor ... 
General Fusion's reactor design consists of 220 pistons that simultaneously ram a metal sphere. This creates a shock wave inside the sphere, so that plasma rings in the center create a fusion reaction.  '' [source]

'' Need a weekend project around the house? Mark Suppes, web developer by day, has built his own nuclear fusion reactor in a Brooklyn workspace. ... While all the components of Suppes' machine – including the deuterium gas – were acquired through legal channels, some of it is somewhat dangerous. His power supply provides 30,000 volts, and his reactor does put off a negligible amount of radiation as it smashes neutrons together.
Suppes' reactor does not generate any more power than he puts into it, and as such is not the golden fusion generator scientists hope will fuel the future with clean, cheap energy.'' [source]

''It’s amazing no one thought of it before: nuclear fusion from a levitating tire-sized magnet surrounded by 10-million-degree plasma. ...
a joint project between MIT and Columbia University  ... The MIT project offers a unique alternative to the two existing approaches to nuclear fusion that dominate the field. Tokamaks attempt to manipulate atoms by surrounding a central plasma-filled chamber with magnets. In an inertial fusion reactor, high-powered lasers bombard a fuel pellet in the center of the device to set a fusion reaction in motion.  ... '' [source]

BTW...
''On the ITER side of the fence, you'll have the largest and strongest magnets in the world: some 14 meters high; some as heavy as a fully-loaded Boeing 747; some 24 metres in diameter. A stone's throw away, on the CEA-Cadarache side, their microscopic counterpart: no more than 50 nanometres in size (50 billionth of a metre!). Magnets by the hundreds of millions packed into one single drop of water. ...  Magnet-producing bacteria are nothing new.  ... Genetically-modified MTB could be used for environmental clean-up or as intelligent contrasting agents in medical imaging techniques such as Magnetic Resonance Imaging (MRI) ...''
