Altogether the participants managed to fly a distance of nearly 10,000km (6,214 miles) with the use of 150 kWh of energy in sum.” That’s about 41.4 miles per kilowatt hour. “Not that bad compared to the world records of the Pipistrel Velis Electro ;-)” Granted that sailplanes are highly optimized vehicles that generate as little drag as anything flying – other than birds, perhaps. Each pilot in the E2 Glide gathering would have used an average of 10 kilowatt-hours of …
