Welcome to WordPress. This is your first post. Edit or delete it, then start blogging!

Creating a clean energy future will require a lot of innovation and people taking responsibility. All summer I’ve been working toward three goals: clearing trees to enable a PV system on my roof’; putting in a large garden; and building an experimental hot-water system by collecting heat from composting wood-chips.

The “Brown Mound” is a densely packed mound of wood chips, with 400 feet of water line coiled throughout. As the chips decompose, the anaerobic bacterial process puts out heat. Anyone with a compost pile will tell you that if you stir it up, even in the winter, you’ll see a lot of steam.

So with that in mind, and some research I did on a frenchman named Jean Pain, we created our own version of a compost-powered-water-heater.

And, it’s working! We’re getting 1-gallon per minute of 95-degree water from the system, only 2 weeks after it was built.  The temp should increase to 120+ as the composting process kicks into high gear. This should mean we burn very little propane to heat our domestic hot water, and we might even be able to heat the house a little by cycling the water from the mound through a radiant-floor loop.

The video below is a “making of” that shows how we build the mound, with the help of lots of friends and people involved in the Carbon Shredder organization. (Carbon Shredders are also co-sponsoring the KickGas Festival with groSolar in San Diego which includes a solar-power sweepstakes/drawing on Oct 24).

Cheers!
