RESEARCHDecember 5, 2008Radio technique keeps fusion gas in place Hit
the right type of helium gas with the right frequencies of high-power
radio waves and you have an efficient way to drive extremely hot gas
around inside a fusion reactor. The ion-cyclotron-frequency mode-conversion technique efficiently confines plasma and minimizes turbulence, key prerequisites for future higher-power fusion reactors that could one day generate more power than they consume. Fusion generates energy by fusing atomic nuclei at extremely high temperatures and pressures. Fusion is how the sun is powered. The fusion reactor control technique is an advance on the long road to harnessing fusion as a practical energy source.
