What happened?

If Ned is right about the refrigerator, can't you measure it by putting a Kill-a-Watt meter on it?

There is a thread going on at:

where several technical engineering criticisms are made concerning the Rocket Stove Thermal Mass Heater.

Are there any engineering types here who could go over there and  respond to them?

I think the best approach is to first find out exactly what amounts of energy you are using for each function. For electricity you can get a Kill a Watt Electricity Usage Monitor
(for example at Amazon) and you plug  your appliances into it. For example I plugged my refrigerator into it for about a day and found I was using about 1300 KWH per year. So I replaced it with a new energy star refrigerator which uses about 335 KWH/year.
