Several groups are working on this. We could gin up a list. One I find interesting: Wright Electric don't have an airplane built yet, but an interesting blog giving insight on how companies start up nowadays.
Details are conspicuously missing. They assume battery technology will improve in the next decade. I guess it's possible to pack lots of lithium batteries, have a rail gun launching, and delete pilots/crew. Safety issues though. For short distances, riding self driving minicars while sleeping should be competitive.
