A great and interesting project, and I'd love one, but I can't really make out what demonstrates that the technology is in its infancy. We know it is, but how does the light weight of the 'plane come into the equation?
A comparison between two non-alikes such as a road car which rolls and therefore can support more battery weight, with an aircraft which has to be propelled forward AND lifted, is a non-starter.
Regarding progression to commercial use.........without miracle electrical storage, I don't think so!
