Reducing dependence on foreign sources of energy is a stated policy goal of the United States. You might think, therefore, that the United States would be eager to take part in an international research effort to harness the energy released by fusion reactions like those that occur in the Sun. But you'd be wrong. Congress just cut the U.S. contribution to the $12 billion International Thermonuclear Experimental Reactor (ITER) project, a collaboration between the European Union, China, India, Japan, South Korea, and Russia.

In theory, fusion technology has the ability to provide massive amounts of energy with less radioactive waste and little pollution. Sounds good, right? Of course, the technology is very experimental and rife with such minor problems as, oh, how to heat atomic nuclei to the 100 million degrees required in a fusion reaction and still generate more energy than was used in the process. It may sound like something from Star Trek, but the rewards that could be gained by investing in such technology are astonishing. The United States might someday be able to retire older nuclear fission plants, reduce coal power emissions, and maybe even end imports of oil from unstable regions of the world.

Too bad the U.S. Congress doesn't feel the same way. Along with slashing technology budgets in other areas of crucial R&D research, Congress couldn't be bothered with funding a $149 million commitment to the ITER project for the upcoming year. The 2008 energy and water bill does provide funding for alternative technologies such as solar power ($200 million), ethanol ($250 million) and hydrogen-cell cars ($235.4 million). Fossil fuels managed to grab the biggest piece of the "alternative energy" pie with $708.8 million in funding.

With all the gains that might someday be realized by fusion technology for such a small investment, it makes you wonder where the United States' priorities really lie.
