Let us get one thing straight, smartphones take a long time to get fully charged and runs out of charge as quick as well, so portable chargers are a handy thing to carry all the time. It doesn’t take a huge space as well. But what if you could charge your mobiles just by the noise that surrounds you all the time?
Come to think of it, it’s a pretty good idea in the first place but how achievable is it? Well, it has been already to be honest as scientists from Queen Mary University of London and Nokia have created an energy-harvesting prototype (a nano generator) that could be used to charge a cell phone using everyday background noise – such as traffic, music, and our own voices.
The device generates around 5 volts, which is actually enough to charge the mobile in the first place. But it’ll be a while before it is actually released in the market and might be even longer when it is available in a cheaper cost.
The fact that everyday background noise are enough to charge the mobile makes this device much more attractive and compelling to make everyday life easier. The idea is truly a billion-dollar idea if its marketing is successful.
“Being able to keep mobile devices working for longer, or do away with batteries completely by tapping into the stray energy that is all around us is an exciting concept,” said Dr Joe Briscoe from QMUL’s School of Engineering and Materials Science.
