The moon contains 10 times more energy in the form of helium-3 than all the fossil fuels on the Earth,' former Indian President Abdul Kalam told attendees at 2004's International Conference on Exploration and Utilization of the Moon. Gerald Kulcinski, director of the University of Wisconsin's Fusion Technology Institute, thinks helium-3 could potentially power future long-distance space travel, though it could take decades before a commercial helium-3 reactor becomes available.
The Chinese space program is interested in harvesting helium-3 from the moon. Some estimates place the value at $4 billion a ton in terms of its energy equivalent in oil.
Any country that brings home helium-3 could be $eriou$ly rich. One space shuttle load could power the entire U.S. for a year!
