[Gasification] Any experience with Stak Properties 10K gasifier?

Dear Bill

Quoting Bill Klein <Bill_Klein at Powerhearth.com>:

# OK!! Do you think one can make "Engine Grade Gas" using:
1: Wood pellets, 1/4" diameter, 1/4" to 1/2" long?
2: Wood chips screened to -1/4", +1/8"?
3: Wood chips screened to -1/2",+ 1/4"?
4: Wood chips screened to -1", + 1/2"?

Thanks!

Kevin
