EV Heating (and Cooling) Could Revolutionize Energy Use

EV Heating (and Cooling) Could Revolutionize Energy Use

Electric vehicles can already be fuel-efficient. The Tesla Roadster claims over 90% efficiency from batteries to wheels .

Along comes the Pacific Northwest National Laboratory (PNNL), which presented at the recent 2012 ARPA-E Energy Innovation Summit that ran from February 27 to 29 in National Harbor, MD, showcasing its molecular heat pump for electric vehicles. Its eventual plan? “A 5-pound EMOF-based heat pump [electrical metal-organic framework] the size of a 2-liter bottle could theoretically handle the heating and cooling needs of an electric vehicle.”
