I remember it too, the Wrightspeed powertrain project. One advantage of the microturbine engine was its capability to handle basically any fuel, including landfill gas.
Microturbines, or a turboshaft engine for those more familiar with helicopters, seem quite reasonable for a series hybrid, as they tend to operate better at a steady RPM and throttle-response is too slow for making good use of any other driveline.
