Have you ever heard the expression “it just appeared out of thin air”? You might see something appear out of thin air on a Star Wars. But the future is coming alive before our eyes because now scientists say they can generate electricity from thing air.
Scientists in the U.S have announced that they have invented a device that can pull electricity from the air using nano-wires. They said this device is strong enough to power a liquid crystal television and can recharge all on its own.
The device is quite complicated, but the premise is simple. It is harnessing the natural electricity in the air like lightning does in a cloud; only it is controlled and not dangerous. Just like in a cloud, there are positive and negative particles that build up and create lightning; they can pull these same particles from the air with the nano-wires and produce a stream of electricity.
The device depends on the amount of moisture in the air, just like a cloud for a lightning bolt. The more moisture in the air, the better the device works. The more ambient humidity, the better the electrical charge.
At the moment, scientists say these electricity harnessers can only charge small devices. Still, they are working on linking them together or building larger tools to help power even more important things like charger cars, powering a house, or even one a small city.
The future is wild, and we could have never imagined some of the things scientists have come up with to make our world a better place. Will this be the way we power our homes and towns in the years to come? Will it help us loosen our tighten grip for fossil fuel dependency? We will have to wait and see, but for now, it is all up in the air.
