Wind And Solar Together
Solar and Wind Energy From the Same Device
Charles Q. Choi, 24 May 2016 (IEEE Spectrum)
“…Cities are growing smarter as networks of electronics help them monitor and control infrastructure and services…[These devices could soon] be powered by renewable energy sources… [S]cientists have developed a flat device that can harvest energy from both the sun and wind at the same time, according to Efficient Scavenging of Solar and Wind Energies in a Smart City…Instead of relying on wind to spin a rotor, the device instead makes use of the triboelectric effect, the same effect behind everyday static electricity. When two different materials repeatedly touch and then separate, the surface of one material can steal electrons from the surface of the other, building up charge…The researchers coupled a triboelectric nanogenerator with silicon-based solar cells…In experiments, the generator could deliver up to about 8 milliwatts [mw]of solar power and up to 26 mw of power from the wind. It could charge a lithium-ion battery from 0.2 to 2.1 volts in 10 minutes, and could also power the kind of temperature and humidity sensors one might find in a smart house…” click here for more
