I think this is the philosophy behind the "Whispergen" stirling
engines. -
Electricity is produced as a by-product of home heating.

Sorry 137 KWh a day is the correct value.

But if you use a higher temp difference.

In my case I warm the house with pellets and say I have a stirling
engine in a pre stage to my heater. pellets burn with a temp around 1200
C

1200 + 273 - 300 / 1475 = 79%  1/3 => 27% This goes to the electric
generator.

I guess the losses are in heat so it can be used it to warm the house.

I use about 1000 kg of pellets a week for warming in the winter ( big
house ). The total energy used a day is thus 1000 * 4.8kWh = 4800 KWh
Say I have 20% efficiency for the electivity generator I can take out
960 KWh a day in electric energy!!! and have the rest left to warm the
house.

Do I have a fault in my thinking here?
