Energy harvesting proliferates in land vehicles #tech #news

It started with the bicycle dynamo and now no self-respecting vehicle designer ignores the possibility of many forms of energy harvesting in his design of a land vehicle. As the illustration shows, the alternator often goes backwards during coasting and braking of a conventional vehicle. Planned versions of these will even provide torque assist in conventional vehicles when needed, intermittently doubling as a traction motor from a more powerful battery. Then even a motorcycle engine may suffice. Regenerative braking is old hat with electric vehicles but nowadays it tends to be done more elegantly with the motor working backwards not driving a separate generator. Having a wind turbine snap up when the vehicle is parked sounds silly but it is at least a possibility given what already happens with all those boats in marinas. Thermoelectric harvesting on the engine or, for hy...
