I didn't say it couldn't be done, I do say it will cost like he** and it will also take up a sh** load of energy, more than we have now to give. We would need to build many more generators than we have now and the cost in energy would be tremendous. We would not be gaining anything unless we build mostly nukes. I do know the difference between magnetic coupling and electro/magnetic waves although there is very little difference and they both use the same principle to function, the transfer of electricity by electro/magnetic waves. Two coils interacting closely use electro magnetic waves to function. This is how we generate electricity, run a magnet past copper wires and it generates electricity.

I stand by my statement that this will be cost prohibitive if large numbers of vehicles are charged this way.

Frankly if it saves a buck, I see the Chinese doing this as they make their country a vast bumper car arena.

They have yet to build roads, and they are building 25 nukes. Build 100 more. It may make a lot more sense than buying oil.

“I do know the difference between magnetic coupling and electro/magnetic waves although there is very little difference and they both use the same principle to function, the transfer of electricity by electro/magnetic waves.”

Sorry calex59, this is absolutely wrong. Electromagnet waves have an electric and a magnetic component, while a transformer uses magnetic only. They are not the same thing.

As an example, if you apply an ac voltage to a wire, a magnetic field will be generated around the wire. When you reverse the voltage on the wire the field collapses and the energy goes back into the wire. It’s referred to as back emf. This is inductive coupling.

On the other hand, electromagnet waves propagate from a wire and the energy is gone from the circuit.

Another example would be a inductive cook top on a stove. You turn on the top and it draws very little current until you put a conductive pot on it.
