Michael Judd says that if permies.com brings in $5000 to his kickstarter, then permies.com can decorate an entire page in his new book!
I'm not sure what we would put there just yet, but the opportunities for comedy are endless!

I stumbled across this today and thought it looked very much like a rocket style device. They used forced air for combustion, and a heat exchanger for hot water heat. From page 6, "The heat exchanger and combustion can are connected to a storage system through pipes large enough to permit gravity circulation. An open-to-the-atmosphere expansion tank will prevent overpressure." I think ernie and erica will be able to glean a lot of useful information from it, it gives a lot of information regarding efficiency and exhaust gas makeup.
