I have a wood gasifier that can run a generator as can be seen on my web page below. I also have two charcoal gasifiers, one runs an Onan 400 watt generator and another a Case 446 lawn tractor. During the winter of 2014/2015 7 of us in the area got together and built 7 charcoal gasifiers at the local high school. Nothing has been posted about those gasifiers.
