The hunger getting the next source of renewable energy is ongoing, whereby there is no natural sensation under consideration. We already hitched the might of moving water, wind, and solar, and the research of the next pure source of energy is far from over.
Over the last years, the rain did not get any attention as a source of providing clean, renewable energy. Well, someone came to think of it, and it is among topics of discussion as we speak now. Maybe, someone feared to bring it on the table among the choices since it would come with problems of hitching electricity. Efforts are made, and in the previous success, the United States and Hong Kong scientists were able to produce 140 volts of electricity from a lone drop of rain. That is enough to provide light to 100 LED Lights for a diminutive period.
That idea is not as new as it sounds. There were previous efforts made to produce electricity from drops of rain, and they all have utilized the triboelectric effect. This is when specific resources obtain electric charge after coming into contact with another material and then disperse from each other. Think in this way; assume that it is a form of the static energy-containing minimal charge of electricity. The previous efforts failed to become successful since they underwent through the effect of expertise.
The group behind the existing raindrop electric generator pushed these precincts further. Scientists from the City University of Nebraska-Lincoln used two years researching on the compactness of energy from a droplet of the electric generator, or DEG.
The actual thing the team did was to design a pitch of transistors consisting of three-terminal equipment that uses an electric field to regulate the flow of electrical current as it passes through them. A great appreciation for this particular design, the density of the DEG rose to over 50 Watts for every square meter. This translates to thousands of times more energy density of the same equipment.
That was not all. In their thirst for hoe, to harness the power of raindrops, researchers used a crucial material, namely tetrafluoroethylene (PTFE), to cover the generator. Tetrafluoroethylene is a hydrophobic polymer that rarely gets wet and can withstand any rise in temperature. It contains what researcher term as a quasi-permanent electric charge. When a drop of rain hits the surface of the PTFE generator, it connects the two conductors forming a closed-loop circuit, which produces any packed energy charges in the exterior of the material.
