The Current State Of Fusion
Alan Boyle at Cosmic Log has the latest broad look at the state of Fusion. He discusses the state of laser fusion. The the $3.5 billion American National Ignition Facility seems to be doing well. But what excites me is that he has some indirect news on The Polywell Fusion Reactor experiments. The dark horse in the fusion race is an approach known as inertial electrostatic confinement fusion, or Polywell fusion. This method, pioneered by the late physicist Robert Bussard, involves designing a high-voltage cage in such a way that atomic nuclei slam into each other at high speeds, sparking fusion.That is the hope. Now what about some news? In September, EMC2 Fusion was awarded a Navy contract, backed by $7.9 million in stimulus funds, to develop a scaled-up version of a Polywell fusion reactor. Development and testing of the device is expected to take two years, and there's an option to spend another $4.4 million on experiments with hydrogen-boron fuel (known as pB11).My sources on the project have dried up as well. No one is talking. I am running on unsupported rumors and conjecture. Some think that the silence is a cover up for failure. Being a fanboy I'm more inclined that they are so wildly successful that the Navy doesn't want to let the cat out of the bag any sooner than they can help. Reality is probably some where in the middle or worse. The design is so simple that if the Navy gets it to work no country is more than 5 years behind in producing a working model from scratch (given a crash program). As you know I have been closely following the progress of the WB-X contracts at EMC2.
