Engineers at Sungkyunkwan University in Seoul, South Korea, have found a way to convert sound into electricity. Enough electricity, in fact, to perhaps one day power your cell phone.
Researchers have found that 100 decibels of sound, which is about as loud as a jackhammer, traffic on a busy freeway or a shout, can be converted to about 50 millivolts of electricity.
While this isn’t quite enough to power a cell phone, the fact that these researchers can successfully convert sound into electricity means the potential is there. As this technology further develops over the years cell phone users may be able to charge their phones anytime and anywhere a high level of noise is present.
Stuck in traffic? Roll down your window and let the sweet sound of angry commuters juice up your phone. At a concert? Your cell phone can recharge as you hold it up like a modern-day lighter.
Experts say you could even power your phone by yelling at it – though we’re not sure the added stares would be worth the extra charge.
