Similar concept to this unit. Had this for approx a year and it is amazing how we'll it works. This thing really hums when the stove gets heated up. I often thought it would be fairly easy to harness the electricity this unit produces and use it for other applications...
looks like they are planning their events via facebook and twitter.....

i love this stuff..... can spend hours watching... if you get board do a search for a "cobb stove" in youtube. similar concept with virtually no emissions, mainly water vapor..... and heats the entire home with low wood consumption.
cool stuff. thanks
