Nextbigfuture had a recent interview with Dr. Jaeyoung Park and is still in active correspondence with him.
If there are any questions you have about EMC2 Fusion's electrostatic fusion process and progress for Dr. Park, then please put that into the comments and we should be able to get a response from Dr. Park. NOTE - There are certain sensitive areas for the US Navy who previously funded the work.
The discussion at Talk Polywell on the physics of the prototype fusion reactors and possible ways to improve it are very interesting.
