[Gasification] Enventix: Syngas and Biochar from Waste

[Brian D Paasch]

I would very much like to add a small plasma punch to our gasifier outlet. Was sharing that thought with someone at church Sunday (yesterday) and he suggested I look at welding equipment. And now here is Tom implying the same thing. Two in two days.... need to think about this more....

We had a number of physicists doing basic research, plus a lot of applied development work.  I hold several patents on plasma torches, and am glad to see this discussion of the merits of combining a small plasma input to aid pyrolysis.
