There's a way for fusion reactors to sidestep high-temperature plasmas, steam turbines, neutron radiation and even nuclear waste--and still generate inexhaustible nuclear energy for less money than Google's annual electricity bill. That's the position, and latest mission, of physicist Robert Bussard. In the 1960s, Bussard proposed the ramjet, a paper engine design that would power deep-space vehicles by collecting hydrogen atoms in space and feeding them into a fusion reactor. Now, in a proposal titled "Should Google Go Nuclear?" (video.google.com/videoplay?docid= 1996321846673788606), Bussard presents an alternative to thermonuclear fusion. He claims an inertial electrostatic confinement (IEC) reactor can provide fusion power that is simpler, cleaner and cheaper than would be possible under the various routes now being pursued by the Department of Energy.
