capstone microturbines have generated some interest as a range extender for hybrid electric vehicles, in particular hybrid electric work trucks. their light weight, small size and quick starting time make them ideal as "instant-on" backup power to recharge the main batteries. an example of a hybrid vehicle is the capstone cmt-380, with a 30 kw gas turbine generator running on diesel, that recharges li-poly batteries when necessary. the cmt-380 has a proposed range of 80 miles on battery alone, but when combined with the microturbine that range is pushed to over 500+ miles.
