Solar scientists using bacteria to realize 'air power'

Was not involved in the work of Chinese Academy of Sciences, nanjing university of aeronautics and astronautics nanoscience institute wan-lin guo said that the new method should be seen as a & other; A milestone & throughout; 。 Since then, people learned that many other bacteria can make proteins nanowires, electron transfer to the environment or sediment bacteria. According to reports in the science, 15 years ago, so the heat exchange station flow chart of the university of Massachusetts, a microbiologist at Derek Lovley and colleagues found a kind of bacteria, called Geobacter can transfer the electrons from organic matter to metal compounds. Wan-lin guo said, & other; Air power & throughout; Does not require an external power, than solar panels or wind turbines applicable scope is wide, therefore, if we can expand, it will show & other; Great potential for the practical application of & throughout; 。 In the beginning, his mentor, the electrical engineer Yao Jun skeptical, but in the end, they found that if the nanowire thin film sandwiched between two block used as electrode of gold plate between, heat exchanger station flow chart and don't control it, they can be power for at least 20 hours. Yao explained that solar portal, silicon thin film at the top and bottom of the electric charge differences led to the electron flow. Air power, he said, seemed to offer a infinite power, heat storage but he said the technology is still no clear electronic sources. Two years ago, new energy, small business at the university of Massachusetts doctor Liu Xiaomeng noticed that isolated nanowires will spontaneously generate an electric current.

electricity generation by using thin air sounds like science fiction, but a new technology based on nanowires & ndash; — Generating bacteria, can do this in contains moisture in the air. Silicon chip, researchers said power the first half of the secret lies in the thin film absorbed moisture, formed the moisture gradient, water droplets spread from the upper part in and out, the droplets can be decomposed into hydrogen ions and oxygen ions, lead to charge gathered near the top. The Max Planck institute of Marine microorganisms microbiologist Dirk DE Beer has reservations about going on the results of this paper. After continuous test, China solar power network, the researchers found that when put nanowires in a wet room, current will decrease, indicating that the humidity is generated by an electronic key factor. Wan-lin guo research water v power generation technology, which is a way to get electricity from the water molecules. On February 17, the new research, published in nature suggests that generating a protein produced by bacteria filaments, can generate enough energy to light the LED bulbs. This leads to a small current, solar equipment, researchers have tried to use it as a clean energy use, with varying degrees of success. Yao's team reports that solar pv projects in the new device, the space between the nanowires seems to help keep the humidity gradient, solar photovoltaic project to make power generation can last more than two months. By moving the equipment exposed to different humidity, the researchers found that the method under the condition of the air humidity is 45%. While researchers aren't sure how the protein filaments work, but the powerful miniature generators: 17 such equipment linked together, can produce 10 volts, enough to supply power for a mobile phone. As a result, the new device running time sustainable weeks, its output power is equipment more than 100 times before. And this equipment can be self charging, photovoltaic (pv) grid, the trick is to let nanowires film side is exposed to damp air, China solar power network, and make the roof is smaller than bottom. New energy small business but before using the water vapor conductive attempt, only a small amount of current generated in a short time!
