Evaporation and Bacteria as New Sources of Energy

Evaporation and Bacteria as New Sources of Energy

The first device, Evaporation engine, is made up of thin plastic tapes on which spores were deposited. These tapes, thus, contract in the dry environment and expand with the increase in humidity and act as muscles. When water is introduced in the evaporation engine, the shutters that are coupled with these tapes, open and close due to the force exerted by the tapes. When the tapes build up enough force to push open the shutters, the accumulated humidity would be released causing the tapes to shrink and thus closing the shutters. Thus, the energy captured from evaporation would be converted into mechanical energy, which can then be stored and utilized in a regulated way.
