I don't have time to read the 1,800 responses, or time for this platform, but yes, I am into physics.
In general, heat is a biproduct of inefficiency in terms of energy loss. Diesel engines are more efficient than gasoline ones, that's why their operating temperatures are lower. If you can reduce anything's heat signature, it's more efficient. Anything that is more efficient is amazing, anything that can conduct electricity without a loss requires less energy input.
So yes, it seems plausible.
I also would apply this more to Electrical Engineering or Computer Engineering than simple "physics."
