A Step Closer To Cheap Nuclear Fusion
ewsnow writes "The Focus Fusion Society reports that the scientists and engineers at Lawrenceville Plasma Physics have finally built an operational Dense Plasma Focus device. While still at less than half power, they were able to achieve a pinch on their device. The small company that Eric Lerner started recently gathered enough funding to start a two-year study on the validity of his theory regarding fusion-inducing plasmoids. If the theory holds, the device will produce more electricity than it consumes. In contrast to the billions of dollars spent on Tokamak fusion (think ITER), LPP is conducting their research on a budget around a million dollars. Yet, if it works, it will provide nuclear fusion with much simpler equipment and much less cost. Eric Lerner and Focus Fusion have been discussed on Slashdot before."
An important facet of LPP's research is that they are pursuing aneutronic fusion. This is truly clean nuclear energy. Explained well here. and here. Nuclear Power without Nuclear Waste: It's Closer Than You Think
Nuclear fusion has the potential to generate power without the radioactive waste of nuclear fission, but that depends on which atoms you decide to fuse. Conventional fusion approaches work with deuterium and tritium, while focus fusion works with hydrogen and boron. When a boron-11 atom fuses with a hydrogen atom the result is three helium atoms and energy, but no radioactive waste. This is because: the fuel (boron and hydrogen) is not radioactive, the reaction product (helium) is not radioactive, and the reaction releases no neutrons (it's "aneutronic").
