Fusing over Fusion
After years of discouraging setbacks, specialists in hydrogen fusion research are banding together to revive the effort to harness energy from thermonuclear fusion. Believers say fusion energy could become a reality in the mid-21st century. Next month, scientists and engineers from around the world will convene in Snowmass, Colo., at a first-of-a-kind meeting of fusion researchers, marking the beginning of a new era of cooperation rather than competition in the field. The main obstacle to accelerated fusion research is the disincentive created by low fossil fuel prices, according to many scientists.
