Bacterial Spore Engines and Applications?

09/28/2017 10:44 AM

Columbia University study of bacterial spore engines

I think this is fascinating! Engine type 1 can produce energy while retarding the evaporative water loss from surface waters (presumption of still waters, I think).

Engine type 2 produces circular motion, could turn small generator, then the sky is the limit (water purification schemes come to mind, where some of the evaporated water is collected by sub-cooling. Battery charging, powering communications, etc.

They even have a gerbil car (not big enough for humans, yet).

True, but maybe not as much output? IDK.

These birds work by warming and cooling of the bird head, right?

The head is cooler than the base due to evaporation. Methylene Chloride condenses in the head and evaporates in the base, moving the liquid higher in the neck. When the center of gravity gets high enough, the bird dips down, dumping the liquid back in the base, and the process starts over.

It's a heat engine driven by the temperature difference due to evaporation.

That one with the mountain goat battle, there has just got to be an easier lunch around here somewhere.
