PV Gap

Lance Said:

can't electric cars be self charging by having a wind turbine emblem on the hood and solar cell material roof?

We Answered:

Not really. Putting a wind turbine on the car just increases the drag and makes it less aerodynamic. Putting solar panels on the roof helps a little, but they're not efficient enough to provide much charge. For example, Toyota has optional solar panels on the 2010 Prius, but they're just used to power the air conditioning and other systems that require little power. They don't provide enough power to charge the car.
