T-LUD Pellet Stove at BSNB4
Kevin Chisholm, July 8, 2006

I have had the opportunity to attend a local event, the BSNB4 on 2 June 2006, where some impressive technology, at early stages of development, was presented. One of the presentations, a T-LUD pellet stove, burning a 25 pound bag of wood pellets in 15 minutes, had a few rough edges, but it certainly brings the T-LUD to a new height. A suitable exhaust hood would, of course, be required for safe indoor use. See picture.

Pema Pot Skirt

There seems to be actual agreement that pot skirts make combustion stoves better.
It is clear however that the bulk of deployed stoves do not have pot skirts.
Therefore an inexpensive pot skirt that could be made in the third and fourth world for those deployed stoves would have some usefulness.
