A rubber band gets hot when you stretch it, and cools down when it contracts. The FLIR thermal IR camera makes this instantly visible. Actually, the rubber doesn't heat until the end, only when you stretch it 95%. Same with cooling. If you build a rubber-band heat engine, it won't work unless the bands are pre-stretched almost to their maximum.

Carbon chains are always buzzing, and if mechanically stretched, energy is injected into those oscillations (they heat up.) If the stretching is released, they cool back to the initial temperature. But, if stretched and allowed to cool by convection, then when released, they cool down below the initial temperature.
It's possible to build a rubber band mechanical refrigerator, or a slow motor powered by small temp difference.
predators have monochrome mode on their masks too, and i acctually prefer it, for when the false colour thermal imaging (closer to their natural sight) becomes jumbled or confusing. this is 33% or their reasoning for masks in the first place

If you want cheap, then you settle for monochrome display with no temperature degrees readings!
