Hello from Milwaukee, WI

Found this site because I've been lurking over at eco-modder. Great Site here! I've been tweaking my hydronic heating system for years now, but an oil-fired boiler is hell to clean. I'm interested in ground source heat pump systems and have been following AC Hacker's posts.
I took an AC motor from an old washing machine and bolted it into place on a walk behind mower where you'd expect to see an ICE, and enjoyed a season of lawn mowing that was so quiet I could hear the birds chirping while I mowed.
I do have trees, so had to be a bit strategic about how to mow without wrapping up the very heavy duty extension cord, but it was no big deal.
Here's to reading many more interesting posts at this site...
