Idea #1: Looking at hybrids - they all can do auto-stop and re-start quickly because of the battery pack and large electric motor. So how can we accomplish this in a non-hybrid and still be able to re-start the engine without beating up the 12 volt battery and frying the starter. Could we use a heavy standby flywheel to have the reserve energy available to restart the ICE? And could the same flywheel drive a small generator to keep the electrical system alive during auto-stops? Use an electric A/C compressor? Idea #2: Design an ultra MPG small pickup, make it very aerodynamic, like this home brew: http://www.evworld.com/view.cfm?section=article&storyid=870 Seems like they could build the aero bed cover and still keep the bed functional by incorporating a roll top section in the middle. Then add all the other known efficiency tricks to it. I would be interested in a small truck that could beat the FE of everything currently made. 1.6 or 2.0 liter turbo four designed for low rpm power. Give it a 6-speed, 5th gear for pulling loads, 6th would be a deep overdrive.
