The car is not going to disappear anytime soon and neither is the combustion engine, despite the inevitable rise in fuel prices. We have said it before, electrical motors are an energy-efficient method for driving vehicles but battery technology is simply not going to advance quickly enough for all-electric vehicles to be a practical reality for most uses anytime soon. The near and mid-term future is undoubtedly a combination of compact combustion engine generators charging dense battery packs that drive electric motors - the "range extender" option. We reported on one possible candidate, the disc motor, a couple of months ago. Now, after nearly twenty years of development another candidate is going through final testing and it is a work of elegant genius - Dr. Herbert Hüttlin's Kugelmotor.
