I find it silly. .. not whose cell they are using but the fact that they are buying drones. Like $ burning a hole in their pocket. as far as the cells, just how many do you think it would take to power a hundred drones? Probably not as many as 25 houses.
if a short screams in the forest and nobody hears him, does he make a sound?
tesla miles range will probably increase over time , perhaps to 405 miles per charge.
Regardless of Teslas stock price ... that in the end will not equate to the success of it, for it is more. It is the Wright brothers, the vision, the technology. and integration, the electric. Like power from lightening.
