An anonymous reader writes: A company called Tri Alpha has successfully kept a ball of superheated gas stable for a record time, 5 milliseconds, putting them closer to producing fusion power. "'They've succeeded finally in achieving a lifetime limited only by the power available to the system,' says particle physicist Burton Richter of Stanford University in Palo Alto, California, who sits on a board of advisers to Tri Alpha. If the company's scientists can scale the technique up to longer times and higher temperatures, they will reach a stage at which atomic nuclei in the gas collide forcefully enough to fuse together, releasing energy. Importantly, the Tri Alpha machine may be able to operate with a different fuel than most other fusion reactors. This fuel-a mix of hydrogen and boron-is harder to react, but Tri Alpha researchers say it avoids many of the problems likely to confront conventional fusion power plants." The article does not say how much this success cost the privately-funded Tri Alpha, but it certainly wasn't in the billions of dollars.
