I'm new to wood gas and after doing some research, it seems the real challenge for the wannabe off grid-er that wants to use wood gas as a primary power source is the time to collect and process feedstock. I wouldn't mind spending one day/mo to collect and process enough wood (from my woods) to produce the 150 KWH's of electricity I need to power my small passive solar house but that would be a stretch and it sounds like its going to take significantly longer than that. That's assuming that I would use the gasifier to power the chipper/saw to cut the feedstock so I'm guessing I would need to process maybe 450 lbs of feedstock.

Wood gas sounds like a great emergency power source and a way for off grid-ers to power equipment or as a backup to solar but as a primary power source, not so much.

Yes, solar is an option and I have a few panels for backup (and a generator) if the grid goes down but I live in one of the cloudiest areas in the US so it would still cost me probably close to $10k to get me off grid which is way out of my budget. With a gasifier, I could get by with a much smaller battery bank since I could charge it daily.

One guy told me he "thinks" he can collect and process enough wood to produce at least 300 KWH worth of wood in a day. If my numbers are right, thats at least 750 lbs! Sounds far fetched to me. Does anyone have any numbers on how much time they spend collecting and processing feedstock per NET kwh of electricity produced? Thanks.
