If anyone on your blog is interested in serious off grid living this is an excellent video on gasifiers. The unit is well built and the video explains it well. Lots of folks don't think these things will work, but they powered most of Germany during WWII because Hitler was taking all the oil and coal for his war effort.
Just for some clarification -- I mention a rheostat that I ordered; I ordered a 25w 20 ohm rheostat. That rheostat will effectively give me the control to adjust the voltage to the blower motor from 12v down to nearly 0v (I think... I'm not an electrical engineer).
