A Sterling heat engine (from +25 to -2°C)

            This third video shows the acceleration of the engine as an ice pack is placed on the top plate which, after two minutes reaches about -2°C compared with the +25°C at the start.

The laser spots are from a radiative thermometer.

This is what happens to the mitochondrial engines in all your cells when you walk outside on a sunny day, sit in the shade under a tree and gaze up at the blue sky that, at a temperature of -40 to -50°C, accepts the waste heat and excreted entropy from your body and radiates it away into the intense cold of outer space. The sunlight has done its job by cascading through the complex processes that keep you alive and leaving all the disorder and heat that life generates to be accepted by the cold blue of the sky. 

The Japanese call it 'Forest Bathing' and know that it works.
