"Squeezing crystals from plant waste generates electricity" Topic

"Scientists have identified a novel protein which generates electricity when mechanically stressed, such as when squeezed or tapped. The discovery suggests that plant waste could be turned into electricity in a more sustainable manner than current traditional methods, i.e. burning.

Everyone was very surprised by the amount of power this tiny molecule called lyzosome can generate. According to Irish researchers at the University of Limerick, lyzosome could easily power electronics like smartphones, motion detectors and all sorts of sensors.

Converting mechanical energy into electrical energy — a phenomenon called piezoelectricity (literally "pressing electricity") — is nothing new. The phenomenon was first discovered and used in the 19th century and one of the most common application being electric cigarette lighters, which use piezoelectric crystals to create a flame. Another common application is the microphone you probably have incorporated in your laptop, whose piezoelectric crystals convert your voice (sound vibration) into electrical signals which are then processed by the computer. There's even a dance club in San Francisco which uses this setup under its dance floor to power the lighting…"
