When will the device be available for our living rooms? Just kidding!
"... The small size has allowed Cambridge Heavy to experiment and iterate quickly. “The small module nature can enable 50 to 80 experiments, 50 to 80 shots per day,” he said. Data from those experiments will feed simulations that use AI to optimize the design. ...
Cambridge Heavy’s fusion reactor uses lasers to compress a fuel target, similar to the groundbreaking experiment that proved controlled fusion reactions could produce more power than they consume. But unlike other inertial confinement designs, Cambridge Heavy’s minimizes the number of lasers required to spark fusion.
The system uses two main lasers to drive ignition.
One laser is split into multiple beam lines that deliver light in concentric rings. Those rings of laser light are timed to hit the flat, round fuel target successively, starting from the outside and working in. The first ring starts a compression wave within the target that starts traveling inward. The subsequent laser rings are timed to boost the wave at just the right moment to further compress the fuel.
As the shock wave reaches the center of the target, a laser fires on the target, generating heat and producing a magnetic field. With the right amount of pressure and heat, fusion occurs. ..."
