A lot of people in e.g. mobile homes in New England and (other areas
of the US
it gets cold in the winter) are stuck with baseboard electric heat;
since the
new administration is so big into crypto it should be decreed that
all electric
space heaters sold in the US should mine crypto, and for the
baseboards you
could also have the baseboard form factor crypto miner.

 
And, the occupant gets to KEEP any coin that he mines!

 
Which begs the question, will the earnings pay the electric bill?

 
I think bitrex's point was that the person NEEDING heat has
already decided to spend the money on the electricity required.
The realization that the heat could be generated while "doing
useful work" is insightful.
 
[I believe electric (resistance) heat is among the least? cost effective]

 
A heat pump is the most productive, of the electrical heat sources.
Mining crypto, dunno.

 
Couldn't you burn gas, boil water, spin a generator to make
electricity, and heat your house with the condensate heat?
 
That would make free electricity.

 
Certainly, and it has a name. Combined cycle, or something similar. It
is a simple as running a diesel generator and heating the house with it
radiator, and a heat exchanger on the exhaust.

 
What is the design life and replacement cost?  Writing off the
investment over a few years could work out more expensive than the
electricity it saved.

 
You have to ask somebody else about that. :-)
 
I read, maybe decades ago, that it was in fashion for businesses in
Britain to do this, and they surely dir make the numbers.
 
The calculation was done for the heating of the building. The
electricity was extra gains.
 

 
Of course when the engine drops a valve on a New Year’s Day with 20 degrees
of frost, you can’t get it fixed before all your pipes freeze and flood the
house.

 
Then use air ducts, as the Canadians :-)

 
I’m Canadian myself, but I never got the knack for washing and cooking with
air alone. I’d probably be thinner if I had. ;)

 
Heh. No, for that you use electricity. As the combined generator is off
(broken), you don't have the space heating, but you still get
electricity from the network.
