(7.3 feet). The electric motor sits on top of the vertical stabilizer and was designed and manufactured for the e Genius by the Slovenian company Sineton. Four lithium-ion battery packs are located behind the pilots in the aircraft center of gravity. The total capacity of this battery system is about 56 kwh. In July 2015 it crossed the Alps from Germany, over Switzerland, to Italy and back in a single day "burning" only some $25 of electric energy. 2011 DA36 E-Star E-Star was the next step in the EADS (European Aeronautic Defence and Space Company NV, a previous name of Airbus) electric journey — first time shown in 2011. It moved from a battery-powered, all-electric airplane that was inherently limited by the energy density of batteries to a hybrid-electric architecture that relied on the combustion energy of hydrocarbon fuel but combined it with the flexibility of an electric propulsion system. It was developed by EADS in collaboration with German company Siemens and Austrian aircraft manufacturer Diamond Aircraft. The DA36 E-Star was the world's first series-hybrid electric aircraft and was based on the heavily modified Diamond HK36 two-seat motor glider. The E-Star's propeller is driven by a 94-hp (70 kw) Siemens electric motor. Electricity is produced by a Siemens generator driven by a small Wankel engine made by Diamond, operating at a constant low output of only 40 hp (30 kw). Quiet, pure electric take-offs were possible due to the capacity of the battery system. 2013 DA36 E-Star 2 "2" stands for a second generation of a serial hybrid electric airplane and was exhibited at Paris/Le Bourget airshow in 2013. It introduced an integrated drive system, significantly improving the power-to-weight ratio of the hybrid-electric propulsion system. Siemens developed an integrated drivetrain for the second generation of the airplane DA36 E-Star 2. It consists of two main components: The electric drive and a generator, which is powered by a small Wankel engine. The hybrid motor glider made a successful one-hour maiden flight at the Wiener Neustadt airfield in Vienna, Austria, on June 1, 2013. EADS CEO Tom Enders, Siemens CEO Peter Löscher, and Diamond Aircraft owner Christian Dries signed an MoU in Le Bourget on June 18, 2013 setting the course for their future cooperation on= electric aircraft development. 2014 E-Fan 1.0 The E-Fan series was born in 2014. This two-seater aeroplane in tandem configuration improved the efficiency of electric flight with a purpose-built aircraft. The all-composite made airplane featured an uncommon propulsion system consisting of At Seal Aviation we repair fuel leaks the first time, every time!
