Labor saving devices are nothing new, but they rarely inspire the kind of dedicated stewardship that antique engines do. This week in Fort Meade, Florida, the 1500 members of the Florida Flywheelers Antique Engine Club opened the gates of their unique 240-acre clubhouse to give the public a first hand look at the fruits of this devotion. If you harbor a secret wish to operate a tractor, bulldozer or backhoe, these are your people.

Spirit Charger Concept SC 01 portends the future of Kawasaki's H2 and H2R motorcycle line

Kawasaki gave us a potential glimpse of the future of it's supercharged product line-up at the Tokyo Motor Show when President Kenji Tomida showed a sketch of Concept SC 01 (SC stands for “Spirit Charger”), which uses softer lines and more luxurious materials than the hard-edged and spartan styling of the 200 hp Ninja H2 and 300 hp H2R. At the same time, Kawasaki showed a newly-developed version of it's supercharged engine which uses electronically-controlled flaps at the supercharger entrance aimed at increasing efficiency and fuel economy.

Retrofittable electric engine adds power and safety to light aircraft

Small, single-engine aircraft are the mainstay of recreational flying, and provide many hours of generally safe enjoyment for hundreds of thousands of enthusiasts worldwide. However, with only one engine on-board, they are also often only a small malfunction away from becoming a heavy, unpowered glider in dire need of somewhere to land. To help improve this situation, researchers at Universidad Carlos III de Madrid (UC3M) and AXTER Aerospace have created an auxiliary electric propulsion unit designed to be installed in conventionally-powered light aircraft to both increase available power and provide extra range in the event of an engine failure.
