New technology converts sound into energy.
Energy is everywhere. We just need to find ways to capture it. The Telegraph reports today that scientists have developed a system that converts sound into energy. This technology would of course be great in mobile phones.
The new technology was developed at the Institute of nanotechnology at Sungkyunkwan University in Seoul (site). Right now the prototype can convert 100 decibels of noise into 50 millivolts of electricity. That is not much. And as guessed the louder the sound the more energy can be harvested. I guess phones are the last device that will get the charge while you talk feature. I could see airports and construction sites as great sources for mind numbing noise that can be leveraged as energy sources.
Any attempt to find ways to use alternative sources of energy is important. We need to get away from fossil fuels and nuclear energy as fast as possible.
