The Future Of Fusion

It's hard to take fusion energy seriously when its proponents employ descriptors like "power of the Sun" and "energy from a star" to explain it. This kind of hyperbole?and the fact that scientists have never created a sustained fusion reaction capable of generating more electricity than it soaks up?make fusion sound like a fantastical scheme devised by Lex Luthor. But in the wake of the current energy crisis, new money and political support may finally channel enough resources into fusion to make the elusive process a reality.

On May 24, the US, EU, Russia, China, South Korea, Japan and India signed on to help build the International Thermonuclear Experimental Reactor (ITER) in Cadarache, in the south of France. ITER is the largest fusion research project to date and one of the biggest international scientific collaborations ever. Its budget is 10 billion euros over 20 years, more than three times that of the Large Hadron Collider at CERN. The reactor is scheduled to be functional by 2016.
