Koenigsegg (Cone-igs-egg), a Swedish car maker that enjoys shocking with its sticker prices, is going hybrid with a new, torque-dense electric motor and hybrid drive train.  The Swedish car maker is known for its ultra-exclusive, ultra-high-performance vehicles, which have even undone the Stig, anonymous race driver on the BBC Series Top Gear. David Koenigsegg’s Gemera manages as much as 250 mph on a two-liter, three-cylinder engine, augmented by a set of three electric motors.  Describing him as, “an inveterate tinkerer” who squeezes “extraordinary amounts of power out of internal combustion engines,” Clean Technica explains the “breakthrough products that could transform the world of electric cars.” One “breakthrough” would seem to be a package of a three-cylinder engine coupled to some powerful electric components.  The “Tiny Friendly Giant (TFG) engine pumps out 600 horsepower (450 kilowatts) and weighs only 70 kilograms (154 pounds).  It has no camshafts, relying instead on solenoid-actuated, artificial-intelligence-controlled valves to let the fuel and air in and …

Amateur aircraft builders, like Francis Marlier of the ULM Club in Alsace, France who recently converted his Exelec to a Sunexelec with the addition of solar cells, are always looking for reasonable options for powering their airplanes. Perhaps they could turn to fuel cells as a range extender. Several motor scooter makers are bringing out fuel-cell powered models that show some promise despite limited performance and high prices so far. Intelligent Energy, an English company, demonstrated a fuel cell scooter in 2005, and a number of aircraft developers, including Boeing, have crafted fuel-cell-powered vehicles. Intelligent Energy’s ENV was reportedly the world’s first purpose-built fuel cell motorbike, and Top Gear’s James May enjoyed the quiet ride, if only moderately endorsing the bike’s sedate performance. http://www.youtube.com/watch?v=igrKemNvxZQ Intelligent Energy’s entry for the Make It in Great Britain exhibit at the Science Museum gives a brief overview of proton exchange membrane fuel cell technology.  “This award winning zero emission electric vehicle is powered by Intelligent …
