this is the solution to the problem of using an electric heater in an EV. instead of wasting a lotta juice to heat the cabin, the driver or passenger could wear a heated jacket inside the vehicle. the capital costs for the jackets would be covered by the increased range, and reduced battery pack capital and mass.
i wonder if you could make a swamp cooler for a car to handle the heat loads. fill up with water at a gas station, or charging spot.
