Guided Impact Fusion
From
Colin Bruce is a physicist and science writer living in Oxford. He is an expert in mathematical paradoxes and a lover of mysteries.
He has a 30 page proposal for Guided Impact Fusion
ABSTRACT
There is a cheap, practicable way to generate energy from fusion. An input pulse of at least 20 MJ X-rays to the capsule is possible (two orders of magnitude greater than the National Ignition Facility achieved): this is known from both theory and experiment to be ample for fusion ignition.
The method is similar to the NIF: a fuel capsule implodes within a hohlraum. However the hohlraum is heated not by lasers, but by the impact of fast pellets. A related idea was proposed before powerful lasers existed, and charged microspheres have been fired at ultravelocity from modified particle accelerators since the 1960s. However, a key enabling technology did not exist at that time. It is now possible, using COTS (commercial off the shelf) available equipment, to track and adjust the position and orientation of many thousands of pellets individually as they fly down a long beamline. This is a multipotent enabler.
