Charge While You Drive

May 29th, 2012 | By Aubrey Yee

You just got a shiny new electric vehicle, you’re hip and ready to go. Driving could be a dream, but where are you going to “fill up”?

What if you could charge your new car while driving it? Sounds fantastical, but actually the ability to charge while you drive with wireless technology may be just around the corner.

Researchers at Stanford have come up with a wireless charging technology that uses “magnetic resonance coupling” - in other words, copper coils in your car and in the ground transfer electricity between each other while you are driving. Charge while you’re driving and you never have to stop to refill your battery!

This potentially revolutionary new system is outlined in a paper recently published in the journal Applied Physics Letters.

While there are some kinks to be worked out, the idea behind the technology is quite innovative and tackles head on the “range anxiety” that many people feel when deciding whether or not to purchase an electric vehicle.

Imagine a carpool lane magnetized for electric cars only. It would require tearing up some of the freeway pavement, but the metal coils needed to make it run are very affordable. One more important innovation on the road to a new way of driving.

The Clean Car Calculator

May 25th, 2012 | By Nicole Rogers

Until now shopping for a high fuel efficiency car, like an electric or hybrid vehicle, could be confusing with overwhelming amounts of data to digest and compare, but students at The Bren School of Environmental Science and Management at The University of California, Santa Barbara have just made it seductively simple.

Enter the Clean Car Calculator: an elegant online calculator that allows the consumer to compare any two high fuel efficiency vehicles on the market, providing a financial and environmental analysis of the cars and even recommending other vehicles to consider given the user’s criteria. The calculator allows the user to adjust for as many or as few variables as desired, like the car’s primary use, percentage of highway miles driven, government tax incentives, etc. One of the most valuable aspects of the calculator is that it determines how long one must own a high fuel efficiency vehicle for it to make economic sense in fuel savings.

The idea for the calculator was inspired by a homework assignment. Project manager Kate Ziemba explains:

The Calculator resulted from an assignment in the Energy and Resource Productivity class taught by Dr. Sangwon Suh at the Bren School that challenged students to understand the return on investment for businesses and consumers to implement energy saving technologies. Students compared lifetime costs and emissions of conventional gas versus high efficiency vehicles. The graduate student developers were surprised to find that hybrids not only paid themselves back in fuel savings, but also that newly released vehicles, such as the Volt and the Leaf, were smart purchases even without a government subsidy.

There you have it! There is more data everyday to show that electric cars and hybrids make sense for the environment and the consumer. But don’t take our word for it - check out the calculator and have fun comparing a few of your favorite green dream cars.
