Interesting idea. I'm actually more skeptical about it being electric than I am the wing/leg configuration. There are a lot of factors that affect power usage--ask someone about running their electric car's heater--and the energy reserve in a battery is pretty slim for a plane that needs a landing strip. For something that makes quick hops and can land almost anywhere it makes sense. 35 years in, I'm more and more convinced that most engineering is just advanced, creative, shopping.
