“General Fusion, a startup in Vancouver, Canada, says it can build a prototype fusion power plant within the next decade and do it for less than a billion dollars. So far, it has raised $13.5 million from public and private investors to help kick-start its ambitious effort. General Fusion says it can achieve “net gain”–that is, create a fusion reaction that gives off more energy than is needed to trigger it–using relatively low-tech, mechanical brute force and advanced digital control technologies that scientists could only dream of 30 years ago. It may seem implausible, but some top U.S. fusion experts say General Fusion’s approach, which is a variation on what the industry calls magnetized target fusion, is scientifically sound and could actually work. It’s a long shot, they say, but well worth a try. Power pistons: General Fusion’s reactor is a metal sphere with 220 pneumatic pistons designed to ram its surface simultaneously. The ramming creates an acoustic wave that travels through a lead-lithium liquid and eventually accelerates toward the center into a shock wave. The shock wave compresses a plasma target, called a spheromak, to trigger a fusion burst. The thermal energy is extracted with a heat exchanger and used to create steam for electricity generation. To produce power, the process would be repeated every second. / (There will be more discovered with this process than meets the eye. – JWD)” – Source
