Robert Adam helps run the Green Speed Cup, a time, speed and economy run for aircraft in Germany. The rules for this year’s contest elucidate the intent and ambitions for the event: “The GREEN SPEED CUP is an aviation competition focusing on efficient flight. The emphasis lies on fast and energy saving transportation.

In making the ability of certain aircraft and techniques transparent, the competition shall set new standards in general aviation.” The Cup provides a sounding board for discussion of energy efficient flight and the changing experience of flying while exploring new techniques and technologies. Hosted by STEMME Aviators e.V., the contest is open to “all aircraft capable of taking off under their own power,” with the following restrictions: In the Electric Class, airplanes may have one to four seats, weigh up to 2,700 …
