What if they had a Tesla merry-go-round where instead of charging your Tesla, you connected it to this giant horizontal ferris wheel that spun it around and charged the battery? It could be wind powered!

You have to pull it forward instead of backward but beside that it is not too different from a wind-up car, don't you think? Teslas do not support car-to-car charge transfer for a situation like this, do they? Nice to know that this actually works though.

Charging stations should be giant hands that pull the car backwards!

I wonder if we'll ever have recharging drones that sense your car is running low, pull ahead of you, and just start towing your car for a ways so you don't even have to stop.

It seems like the tire wear wouldn't be worth it. You're pulling the tires at almost 100 horsepower of energy transfer. Sure, neat for a video gag though.

I guess conveyor belts under the wheels would have similar results, probably with less moving parts.

But then... why bother, just plug the car to the power source making your marry-go-round go round! Otherwise this is a lot like putting salt on a birds tail to catch it...

I assume this is tongue-in-cheek, but just pulling up close to you and springing out a charging cable arm would be more efficient.

At that point, why not just have drone chariots that pull you the whole way

So basically teslas are wind-up toys.

I wonder how efficient this could be made (I'm picturing something like a dyno)
