An unmanned, electrically powered craft developed by NASA can take off vertically and convert in flight to an airplane-like configuration for efficient cruising, before converting again to land vertically. The GL-10 Greased Lightning uses power-dense batteries and leverages the considerable weight-distribution advantage of electric motors over heavy fuel-burning engines. The experimental design demonstrates the feasibility of electric power for future aircraft that will eventually replace highly inefficient helicopters, according to this article.
