Google Siemens electromobility. Click on the banner with that name. On the website, click at the right on the video labeled "Inductive charging". Great video.
WHY has Tesla not picked up on this? No need to plug the cars in. Just drive over a charger and press a button on dash. Car starts charging through induction from coil under the pavement.
I'm retired from GM and I've urged GM to look at this for the Chevy Volt and upcoming- and spectacular- Cadillac ELR. See it. Chevy dealer here had not heard of it!. Said you'd want to keep the ability to plug the car in even if car could do wireless charging from below.
Siemens says the charging can be faster from under the car. There is even a small company now in Virginia selling these systems for the Leaf and Volt. See www.pluglesspower.com. Evatran is the company. See presentations on UTube by Sales and Marketing Director of Evatran Rebecca Hough. They say Sears is installing the unit on your garage wall and the unit on the garage floor. You have to have a Chevy dealer install the receiving unit in your car.
Evatran says a "growing number of Chevy dealers are handling these". Wonder what GM thinks of that.
I told GM that I envision a tamper-resistant meter in the car that records where (GPS) and when (clock) you take on electricity. It transmits this info. wirelessly continuously to the power company. If the car takes on electricity at a shopping mall, office park, university, med. center, factory, etc, that entity's electric bill could be credited. The car would identify itself to the utility. The owner's electric bill would show any electricity he took on at home and any he took on elsewhere.
BTW team at Stanford has proven on computers that cars can charge by induction AS THEY TRAVEL ON HIGHWAY. Google wireless energy transfer can revolutionize highway travel Stanford. Click at right on the page that comes up on GCEP forum 2011. There see the video by Prof. Fan on light scattering and then wireless energy transfer. Ph.D in Physics from MIT.
