Nuclear fusionPublished: 2016-06-30 | Original Article
If there's a Holy Grail of clean-energy generation, it's nuclear fusion, which promises limitless carbon-free power without producing dangerous nuclear waste. By figuring out how to mimic the same kind of atomic reaction that occurs at the center of the sun in a controlled way, fusion reactors could supply a whole lot of energy with little environmental cost.
While the technology may be 30 years from maturity, defense contractor Lockheed Martin has made inroads. In October its researchers developed a small fusion reactor design—one that might someday fit in a tractor-trailer and produce 100 megawatts of power. The company hopes to have a working prototype in five years and a commercial version within a decade.
