Lolol, even short distance- batteries cannot compete, they (the Drone makers) will figure out a way to carry the most groceries to the door and heavy DEADBEAT BATTERIES in cold weather are totally undesirable- JACK! FYI
It's not about range, it's about operating time and performance. Battery droop is a nagging problem for any battery-powered vehicle, and it would be doubly dangerous in a flying vehicle.
Not to mention the productivity gains, when H2 powered vehicles are 4 times the range of a battery powered one.
