I think I'm getting it...

Many thanks for all the responses to my layman's question! I think I'm now seeing some of the problems with a net-power producing magnetically shielded gridded fusor: --It doesn't solve the thermalization problems; after not too much time in operation, the fusor would be choked with ions too low in ...

Could Polywell research enable Farnsworth-Hirsch fusors?

The biggest problem with a Farnsworth-Hirsch fusor--which the Polywell is designed to solve--is the fusor's physical grid. The fuel ions in an F-H fusor tend to impact the grid before they have a chance to fuse, leaving them with insufficient energy for fusion. Furthermore, the grid is relatively fr...

Thoughts about reactor packaging

This long-time lurker noted with great interest the recent predictions that the high-energy alphas would be deflected by the MaGrid's magnetic field (if the field were strong enough) and would escape through the cusps. Most of the commentary on the earlier threads had to do with how this affects the...
