rnebelI'm honored Rick thinks that I have made some useful contributions to the advance of this technology.
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.
What most excites me is that we will probably know in two years or less if this technology is viable. That is very exciting.

Why hasn't Polywell Fusion been fully funded by the Obama administration?
If you want to learn more about the basics of fusion (Polywell is a little more complicated) may I suggest:
