If it’s for real, the advance would revolutionize electric flight.
For the past many years, I’ve been the pro side in arguments with colleagues about the future of light aviation. Unlike many of my friends, I believe, to paraphrase William Faulkner, that light GA will not only survive but endure. I do accept that something has got to give technologically. When the means of propulsion—formerly piston engines—along with the cost of care (maintenance and replacement) and feeding (the price 100LL) is responsible for about half the overall costs of operation, something needs to change if we want aviation to expand beyond its die-hard enthusiast niche.
