This hands-on course covers the basic science of composting with various feedstocks optimized to produce large amounts of heat, using a simple, but proven approach of embedding a heat-exchanger into a large mass of aerated saw-dust, wood-chips and/or bark-mulch. Course materials and system designs are based on the pioneering work of the non-profit network at and French inventor Jean Pain. Students will learn about the history of this concept of the "Jean Pain Method" and the early results of CompostPower's experiments in Vermont, while building a Compost-Power system that will be used to create steady base-load heat for domestic hot water, process heat, space-heating or greenhouse-heating depending on the host-site. An overview of HVAC-plumbing-integration or a field trip to an operating system will also be included.

Price: $350
