I'm used to heating with wood anyways, so a wood gasifier is the first thing that comes to mind. An old car engine with nothing to lose and the capacity to have it's output at peak torque (peak efficiency) halved would be just about the thing for any DIY:er. In box with noise insulation and 3 times the sound surpression on the exhaust. The wood gasifier produces a lot of heat itself, it'd make sense to make use of it.
Some sort of auto-feed hopper would be great, and with space being less of a factor with startionary power production than in trasnport it's possible. The main issue here is safety. The engine would run on carbon monoxide, although the noise of the whole system would most likely condem it to the outdoors anyways. _______________________________________________ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
