| IEC Fusion |
Although most funding of fusion research has been focused on tokamak and laser implosion devices, new developments in IEC (inertial electrostatic confinement) fusion using quasi-spherical magnetic fields may offer an important breakthrough.
The following document presents Dr. Robert Bussard's IEC fusion research at EMC2 over the past 17 years, as given at a Google Tech Talk lecture.
- "Should Google Go Nuclear?", November 9, 2006, 1.5 MB (revised August 30, 2007)
Dr. Bussard also gave this talk at Yahoo! on April 10, 2007. It is similar to the Google talk, except he spoke more about the impact on the world towards the end of the talk. A video of this talk is only available internally to Yahoo! employees.
