Herr Doktor Hüttlin’s magical Kugelmotor
From Gizmag via John D comes an invention from the Black Forest area of a spherical engine that can drive directly, generate electricity or store energy from braking in the motor itself. There seems to be considerable potential for it as a range extender in plug-in electrics.
“Pre-production prototypes of 1.18 liter capacity have been in testing for some months and power output at present is 74kW (100hp) at 3000rpm with torque up to 290Nm (213ft-lb). Dr Hüttlin expects efficiency to increase by another 40% with reduced bearing friction and optimization of the combustion. The engine weighs 62 kg and consists of only 62 parts, while a conventional engine has at least 240.” Continue reading Climate clippings 46
