I was reading an earlier post about having a wind turbine embedded in a vehicle to generate electricity as it moved. I came to this site after having this thought last night. But I realized immediately that drag and weight would be counterproductive. However, I did ponder an alternative. What if a small wind turbine was placed inside of the dashboard, in front of the air vent - acting as a small, trickle charge generator that operates when the air conditioner or heat is switched on. It may not produce enough electricity to self-perpetuate, but it could off-put the A/C & heat consumption rate that exists in Hybrid/ Electric technology - effectively making the battery last longer. For it to be effective, a kinetic generator may cause too much resistance. Therefore, what about a copper wire/ magnet current inducer?
