[Stoves] ***SPAM*** Re: [Biochar] Charcoal producing electrical power plant

[Bill Knauss]

Kirk,
I follow what you are doing with your innovative combuster designs for
gassifiers. This is an area of development that we have been ignoring for
too long.  The closest thing to what you are describing as the way you want
to go with your innovations in the future is being done by Phoenix Energy.
