Sahin says: Water wants to evaporate.
It has a desire to evaporate.
If you make a surface wet, it will dry up, thats the natural course.
What we did was find a way to channel that desire into doing some useful work.
Sahin had discovered last year that when thebacterial sporefrom common soil is placed underhumidenvironmental conditions then itabsorbswater and swells.
By using this theory Sahin build the machines.
Sahinsfloating piston enginewas made by pasting a line of spores on each side of a thin plastic tape.
This action is similar to that of an artificial muscle which is powered by changing the moisture level.
The scientific term for this action is hygroscopically driven artificial muscles orHYDRA.
Using this fundamental principle of Hydra, Sahin and his team built arudimentary piston engineby using dozens of hydra.
Next, the hydra was placed inside a plastic case which had little shutters placed overhead.
The entire cycle would keep repeating.
During this entire cycle the piston engine is able to generate enough electricity that can power a LED bulb.
Half portion of this wheel is kept in dry air due to which the tapes curl up.
Due to a tiny mass imbalance the wheel starts pushing forward to balance the moisture level.
With their unique inventions Sahin and his colleagues have given a new perspective to biology.
Sahin says that evaporation can not only save water but it can also generate power.
The entire study and findings of this research has been published in the journal Nature Communications.
