                                         we also look n for 50KW
gasifier  any info  PLS  Thanks Wayne
                                       > Do you have a gassifier of
that range 40 - 50 kW gas, not engine kW ?

..yes, 2 actually, I have one that needs a new home, it's ready to go
wherever you want it, it's fueled up and ready to run on arrival.
The other one is in parts, stored with the rest of my stuff, books,
tools, furniture and ready to move.
