Goodbye Power Cords, Hello Wireless Electricity
Imagine a world where clusters of mangled wires under desks are non-existent. Imagine a world where laptops and cell phones charge every time they enter a room.A world where all those things are possible may not be far away.The idea of wireless electricity dates back more than 100 years to Nikola Tesla and his giant electrical towers, known as Tesla coils, which would relay electrical charges through the air."Tesla made an antenna of the high-voltage end of his secondary, it became a powerful radio transmitter," according to PBS online.
