Stanford Scientists Are Making Wireless Electricity Transmission a Reality
Stanford researchers have discovered a practical method for wireless transmission of electricity, making Nikola Tesla's vision of a wireless power grid a possibility. If the method can be scaled, it will mean much lower costs and greater convenience for electric vehicles.
Nikola Tesla envisioned supplying power to the world without the need for a tangle of wires strung everywhere. The closest he ever came to realizing wireless transmission was the Tesla coil, which he created in 1891. However, his dreams were much bigger, encompassing a global wireless power grid that any home, business, or vehicle could tap into at will.
Now, researchers at Stanford University think they may have gotten the wireless charging technology right, as they’ve been able to transmit electricity wirelessly to a moving object nearby. If their technology is scalable, they may have discovered a way to allow electric cars to recharge as they’re in motion, eliminating issues of charging station availability and EV battery range. If that final hurdle is truly overcome, electricity could easily become the standard vehicle fuel worldwide.
