Ha! ... but had they only known about the miracle Stirling engine, the
one which is supposedly 40% efficient with that kind of heat, then they
could have diverted the hot water flow in the summer months to the
Stirling, and used the power generated from it to offset the normal grid
power bill... Sounds silly, and the devil is in the details, but if it
were reliable, that kind of thing would definitely have a market in the USA.
As Fred Sparber sez: "most farmers will spend a dollar to save a dime"
but then again, he was referring mainly to Pennsylvania Amish farmers.
But Brits can probably substitute "pound" and "pence" in there and get
the same sentiment for the thrifty Scottish farmer, no?
