Hybrid Humvee


If you're not in the military, driving a Humvee can be considered a waste of gas, but lovers of the all-terrain vehicle can soon start thinking green. EnerDel is teaming up with the U.S. Army to develop four possible lithium-ion battery systems to power the Humvee. The company has 18 months to design and test these batteries in “extreme performance simulations,” CNET reports.
