Rick Nebel, the head of EMC2 Fusion (Polywell), has a few words to say in the comments at Next Big Future about the progress he is making in understanding The Polywell Fusion Reactor and its chances for power production.

I believe we will know the answer for the Polywell in ~ 1.5-2 years. I haven't looked at MSimons design, but I know he has a lot of good ideas. We'll probably take a closer look at D-D reactors over the next 2 years.
I'm honored Rick thinks that I have made some useful contributions to the advance of this technology.
What most excites me is that we will probably know in two years or less if this technology is viable. That is very exciting.
