Scott & Stovers,

The Viebach engine can readily be inverted over a conventional wood burning stove run an alternator via a belt drive and start charging batteries.  Viebach has done this in a demo model:

See the bottom of this site for a photo:

You can make out the nest of heat exchanger tubes sitting in the space at the top of the stove next to the flue outlet.

In Winter 1995 I demonstrated one of the early Viebach engines in London.  We ran it for a week, 8 hours a day at an engineering exhibition. We used a 3kW propane burner to supply the heat. The mean electrical power output was 350W or about 8kWh per 24hrs.

If you go back 100 years - almost all hot-air and Stirling engines were solid fuel fired, Rider, Ericsson, Robinson etc.  The problem was that they were big and heavy made from cast iron - Viebach engine weighs 50lbs and benefits from much more efficient heater and cooler.

Viebach has sold at least 100 systems to amateur enthusiasts, and is now offering an integral generator.

Look at the Uwe Moch site for the prices
