At the University of Utah, the mechanical engineer has found a "loophole" around the physical principle that allows the device to be able to move the heat back into electricity. Nanotechnology harvested by placing two surfaces from the object until they are almost familiar with each other. In the future, this configuration can not only be able to cool the mobile devices such as laptops and smartphones, but it can also shut off the battery life of heat.
Device reading, so called "Near Field Radiation Heat Transfer Device", developed by Mathieu Francoeur, Mechanical Engineer Associate Professor Utah Utah. For heat harvesting, the device's strike
The black body is an object that absorbs all electromagnetic radiation (eg, the black body should also be emitted by the same indicator that it absorbs the black body, so that the black body is well exposed – so the waters should be black.
Theoretical blackbody limit tells us that the maximum number of heat that can be released is an object. However, this ceiling is known to have no margin when the space between space is small.
Frenkor and colleagues have developed 5 mm 5 mm chip, which is no bigger than the drying head, the nanoscopic hole made of two silicone wafers is only 100 nanometers thick – this is a 1000m thickness of human hair.
"Nobody can exaggerate more than the black border," he said. "But when we go to nanoscale, you can."
Chip was placed in a vacuum. The researchers then dropped the chip to one side and cooled to the other side in a small space, creating a heat flow that could transform into electricity. Electricity generation is not a novel in this way, but a new learning curve is the ability to demonstrate two silicone surfaces with this effect without touching them without them. Closer to the two surfaces of each other, the more electricity can be generated.
In the US, two-thirds of energy consumed annually lost heat. Froncor in the future is shown on its chip, which lifts laptops and smartphones and channels for additional batteries. He estimated that the battery life could be improved by 50% using this technology. For example, a laptop can last up to nine hours with a charge of up to nine hours. Blackbody chips can also be used to effectively solar panels or automobile devices to convert heat from the engine to electrical systems.
"You get the heat back into the system," he said. "Now, we just broke it into the atmosphere, it's warming up, for example, and then using your AC cool room, which loses more energy."
The researches were published in the journal Nature nanotechnology.
