That's never going to happen. Only a tiny fraction of the population live directly on lakeshores, and basically no warehouses. If drone based delivery is going to work then they'll have to fly out of ground effect to avoid structures and trees.

The main advantage of ground effect vehicles is lower fuel consumption over long distances. That's not a priority for the short range battery powered drones used by delivery services.

I think you are mistaken sir.

I live by a lake myself and i've just talked to my neighbors, and they all live by a lake too.

My startup is working on playing soothing music on drones using differential timing of rotor speeds. We've made some impressive inroads in the past few years. We're planning on adding a model that also plays birdsong for exactly this use case in the next couple of years!
