I think you just described the potential usefulness of drones in terms of energy used for a delivery. A drone only has to carry itself and it's package - compared to a car that has to carry it's weight, the driver's weight, the packages in the vehicle, etc.
I think it boils down to this: How many/weight of items being delivered to energy efficiency is on a curve. Sure trains are the most efficient method of transporting goods, but there's a reason a train doesn't deliver our packages to our doors. Building such an infrastructure would be insane.
That's why current delivery is tiered to the quantity/weight of the goods you're shipping.
I have a feeling drones will be more efficient for small packages, but larger ones will still be best by car.
- ocdtrekkie 7y agoA drone only has to carry itself and it's package, but it has to carry it in a vertical direction, and maintain that (because things in the air without thrust tend to fall back down to the ground, and that's bad). Meanwhile, a car only has to push itself in a horizontal direction around the ground. As you say, the problem with trains isn't efficiency, it's infrastructure for last mile to our doors. However, we already have that for vans: Roads and driveways to our door are already built. If I need a cell phone delivered to my front door, which is going to be more efficient: The van that already is delivering a larger box two doors down dropping it off, or a separate trip from the warehouse to my house from effectively, a small aircraft?
