A compost or possibly a humus pile was constructed to explore the possibilities of utilizing the heat generated from this process to heat a building. The building was a work shop that needed to be kept above freezing temperature or higher during late fall and winter. It did work to some degree but further work needs to be done. With the first version there was a problem separating the water pipes from the compost/humus at the end of it's life cycle.

In Alaska, there are a lot of remote villages that generate electricity by using small oil generators. But, transport costs and fuel costs have made the electricity very expensive, and the costs of heating their homes and generating electricity has been a burden on the businesses and families in the rural areas.
Icy Straits Lumber, in Hoonah, Alaska is testing a small All Power Labs Gasifier at their lumber mill. They have a ready supply of the right kind of fuel, have staff familiar with this type of equipment, and need some extra power, that's less expensive than the imported fuel they'd normally be using. This will be a good place to see if this type of gasifier will work well in the winters in Alaska, and if so, it may be recommended to other communities.

Abstract: An open top down draft gas producer with divorced fuel hopper was constructed and tested. The design progressed through many changes until a stable device emerged.
