Waiting for the Tesla of the aviation as that lead vs. unleaded feel like something ancient. Lets look at numbers as of today: Cesna 172 - 75kw engine, on 50kw power makes 1000km as 200km/hr. Engine plus fuel weight 350kg. The engine costs $26K. Today's lithium batteries like ones used by Tesla is 280wh/kg. At retail similar batteries cost $400/kwh. So, we can have 75kw electric engine and 100kwh battery at the same weight as ICE engine plus fuel on Cesna 172 and at a retail cost of $50K and have 2 hr flight of 400km. That isn't a worse starting point than what Tesla had 15 years ago against ICE cars.
