Consuming less energy and emitting no hazardous fluids, magnetic cooling is a promising new refrigeration technology. EU-funded scientists relied on magnetics to provide cooling to vehicles that run entirely on electricity.
A conventional vehicle typically uses the engine waste heat to run the cabin heating and a gas compression cycle for cooling and dehumidification. In electric vehicles, however, there is lack of available heat waste and the climate control system has a significant effect on energy consumption and mileage.
