Scientists have developed a pneumatic generator with electrically conductive protein nanowires that generates an electric current from moisture in air naturally present in the atmosphere.
Existing forms of renewable energy require sunlight, wind or waves to operate.However, a team of researchers from the University of Massachusetts Amherst has presented a completely new universal option that does not need special conditions, canWork around the clock and even indoors.
Scientists have developedAn Air-gen device whose main element is a thin film of protein nanowires less than 10 microns thick placed on an electrode.In this case, another smaller electrode is placed above it, covering only part of the surface.The film adsorbs water vapor from the atmosphere, and thanks to a combination of electrical conductivity, the chemical composition of the surface of nanowires and small poresBetween them, conditions are created for the generation of an electric current between the two electrodes.
According to the developers, the current variant of the Air-gen is capable of powering small electronics and cangenerate electricity even in areas with extremely low humidity, such as the Sahara Desert. In the future, they plan toTo create a small generator that can provide energy to wearable gadgets or even mobile phones.
In the future, they hope to design large-scale systems for industry and adapt the technology for use as paint impurities .So far, development has been hampered by the slow production of nanowires by Geobacter bacteria, but recently the team has developed a new strain of microorganisms, effectively turning them into a factory for the production of the desired protein.
To combat climate change, researchers aim to extract energy from a variety of natural factors.Last year, scientists created a device that generates electricity from falling snow.</p>
