A team of Bioengineers created first engine that runs on water evaporation -

Bioengineers a team led by Ozgur Sahin at Columbia University recently created the most likely first mover the world that is capable of operating on the evaporation of water at room temperature as reported in the journal "Nature Communications". It is mentioned that using only a puddle at rest, it can turn on the LED or even drive a miniature car. The best news is that it will cost less than $ 5 to make.

The most important part of the engine is a new material that is called hydras (humidity-driven artificial muscles). The material is made from thin muscular plastic strips as contract when dry and expand when wet. It is also able to respond to even a small amount of moisture, it is able to contract and expand to more than a million times and nearly degradable material type. In addition to this, it is also can extend up to four times its original length. Since the material expand and contract, it will create energy and thus can be used to make an action as specified.

How does it work? The motor is placed on a pool of water at room temperature in a small enclosure. As the water evaporates, the closure will certainly become wetter and therefore it triggers HYDRA strips extend. As they grow, they'll pull a rope that is attached to a small electromagnetic generator and thereby converting this energy into motion. At the same time, the bands will also pull open a set of four components on top of the engine releasing the moist air. As the moisture inside of the closure of the drops, it strips will contract and thus close the shutters. The process repeats.

Turning now to the evaporation engine is considered a proof of concept. For it to be implemented for public use, it is still a way to be done.
