Stanford researches may have solved the problem of range anxiety by wireless charging technology that could one day create an electric highway.

Wireless recharging already is used by some electric vehicle charging stations to fill up batteries without cords or plugging into an outlet. MIT helped pioneer this technology and spun it off into a wireless charging startup, WiTricity. However, Stanford researchers improved on this concept and devised a way to transmit 10 kilowatts of electric power across a 6.5-foot distance with minimal energy loss. By overcoming transmitting electricity across a significant distance, researchers will make it possible to pave a highway with wireless conduits that can provide addition power to EVs and let them operate indefinitely.

Utah State University researchers have made a breakthrough in the quest to make in-road electric vehicle chargers practical for the real world, managing to wirelessly transmit 5 kilowatts of electricity across a 10-inch gap with 90% efficiency. That’s huge for a technology that has struggled to gain traction because of inefficiencies and difficulties bridging enough of a gap to make inductive chargers useful in highways, where chargers are a significant distance away from car batteries and need to deliver large amounts of electricity in a short period of time.

What’s happening right now

We use countless electronic gadgets every day. We have got used to them to the extent that we can’t even imagine a life without them. A significant part of our life is spent using and enjoying them. However, charging them can be pretty much difficult. We run into many obvious difficulties while doing so. Generally , there are two widely used modes of charging them. One is to use an AC adapter which delivers electric power to your gadgets. The other option is to use solar power, though it can be used only for certain devices which have a necessary level of compatibility. It is not easy to charge these devices on a daily basis using electric AC adapters. The problem is that you will have to take the wires with you all the time, and you will need to find an electric port to charge them. With solar chargers, weather fluctuations can be the spoilsport.
