The i3 will be powered by huge lithium-ion batteries positioned under the floorboards (a distribution of weight that eases handling) with a drive system, chassis and energystorageunit all incorporated into a body module made of aluminium.
One WindTamer customer is the U.S. Army, which purchased last year a mobile trailer-mounted turbine and renewable energystorageunit containing the Power on Demand system that the military would be able to move around even in battle zones.
By roughly 2008, carbon microfilament capacitive storage devices were able to match the amount of energy stored per unit volume and per unit weight that chemical batteries were capable of.
