Stanford Dreams Up “Electric Highway,” Charging Your EV While You Go

EVs are a great step to cut our impact on the environment and cut the cost to commute. The one strong drawback of EVs (Electric Vehicles) is the range they offer. Currently, EVs like the Nissan Leaf offer ranges of about 75 miles. For many, this may not be enough to justify the steep asking price over traditional gas cars or hybrids. Stanford researchers may have come up with an idea that could change all of that.

Simply calling the concept an “Electric Highway”, the road of the future would use “magnetic resonance coupling” to charge your EV while it travels down the road. Essentially it uses two electric coils using the same frequency, one in the road and one on the bottom of the car. The coils in the road are charged, and when a car with a similar coil attached to it drives past, the electric charge is transferred, charging your EVs batteries.

The idea is rough, and is clearly a very long way from being implemented. It seems good on paper, but it may not be something that would fly until more research is done. For example, how much radiation would a charged highway give off? Also, these highways would be expensive to build and maintain. Considering much of the crumbling infrastructure we have already, this could be an issue.

Nonetheless, the concept is quite intriguing. What do you think? Could this be the future of travel?
