Researchers had built a prototype device which changes movement into power, at the Georgia Institute of Technology.Scientists in the United States said Tuesday it lies within reach, thanks to a smart way to harvest energy called tribo-electricity.
A professor of materials science and engineering, Zhong Lin Wang described the invention a "breakthrough." He told AFP by email, "Our technology can be used for large-scale energy harvesting, so that the energy we have wasted for centuries will be useful."
"Tribo-electric" is a modern device with previous rules from the Greek word for "rub."The device generates electricity from friction between two things that cause a charge of electrons travel from one to the other like walking on nylon carpet with plastic-soled shoes.The device has ability to generates 1.5 watts.
In a new study published in the journal Nature Communications, Wang's team said they had overcome key hurdles to converting a haphazardly-generated electrical charge into current.
There are two circular sheets, an electron "donor" and the other an electron "receiver" moved together by rotary movement.An electrical charge isolate would use if the sheets are separated.It has one more disc with electrodes, work as a bridges the gap and allows the current to flow at a top speed of 3,000 revolutions per minute.
Wang said, "It can run on a gentle wind or tap water, or "random jerky motions," including human movement, to provide the rotation.""As long as there is mechanical action, there is power that can be generated."
Wang also said, "the prototype used copper for the rotator and gold for the electrodes in lab tests, but these could easily be substituted for low-cost synthetics."
The team of researchers is still working to harvest power from the ocean.
