Equipment for evaporating water to produce clean energy

Always water on earthCirculationAnd that the amount of water evaporating from the sea and the land will amount to 1 trillion liters per dayTrial calculationIs also issued. Attempts to create clean energy based on such an enormous amount of "water evaporation" are taking place at Columbia University.

You can see the movement of minicar using evaporated water as a power source from the following movie.

Capturing clean energy from evaporating water - YouTube



A minicar with a device like a windmill appears in the car body.


When the windmill turns around the kurukuri, power is transmitted to the wheel and the minicar moves forward. It is said that the power of the water evaporates in the rotation of the windmill.


This technology takes advantage of the characteristic that when a certain bacterium "swells when absorbing water, it can infinitely move shrinking motion when moisture disappears."


The movement of each bacterium is small, but by collecting billions of bacterial spores and attaching it to a plastic tape, we succeeded in extracting the expansion and contraction of the bacteria as energy.


When moisture is contained in the tape suspended in the test tube, it stretches to rusty ......


When moisture disappears, the tape shrinks.


If you put together a lot of tapes with bacteria attached, you can create a lot of energy.


Ozgur Sahin, head of the research team, said, "To evaporate the water you need to gather light, but compared to using solar panels to create solar energy, using this device costs It can be cheaply suppressed. " The attempt to convert the evaporation of water into energy itself is not new, but this time it was the first time that we succeeded in creating enough energy to move an object.


I will attach a small cut tape to the windmill.


When watering the windmill ... ...


One tape will bend and it will bend.



Attach the windmill to the mini car and tie the windmill's shaft and the wheel with rubber.


Then, the minicar began rolling ... ....



To the research team, specialists in a wide range of fields such as engineers, biologists, chemists gathered and developed machines that convert the evaporation energy of water into rotation and piston movement.


Here is a device with a tape installed under the plate, when water is included in the tape ......


Following the expansion and contraction of the tape, the board repeats opening and closing with a flap.
