[QUOTE="soberups, post: 1831792, member: 14668"] Its cute but it still does not solve the fundamental underlying problem of the power-to-weight ratio of existing or foreseeable battery technology. A drone with enough power to get any amount of cargo in the air will not be able to haul that cargo more than a few hundred yards. Extending the range requires a bigger, heavier battery which means decreasing the payload by a corresponding amount. This is the reason why we do not have battery-powered helicopters or aircraft. The only way around this is to use an internal combustion or jet turbine engine, both of which have the necessary power-to-weight ratio but then you run into the problem of scaling them down to a size small enough to fit on or in a truck. Look at the size of a modern, state-of-the-art helicopter versus its payload, even without the weight of a pilot or a cockpit to put him in there is simply no way for a drone to get a significant amount of weight into the air and fly it a meaningful distance with existing technology.
