Ice.
Lots of ice around, such is the nature of Russia.
So, how about making electricity out of it?
Just having some fun with a thermoelectric generator i made.
A TEG is said to produce electricity from heat, but since it is running on a temperature difference, it's equally valid to say that it produces electricity from cold.
However, i don't think i ever heard it described that way.
And for a good reason - the energy is, in the end, coming from the furnace that heats up the house.
Are there circumstances where it would make sense to say that the power is coming from the cold?
Even in places where heat and cold co-exist, it's more precise to say that the heat is carrying the energy (be it from fire, solar, geothermal, nuclear, body heat, etc), and not the cold.
