This is one way (of about 5 ways) to produce wireless energy transfer. Other methods include: directed microwaves, lasers, tuned induction and most recently simply energy picked out of the airwaves (presently for small devices) Even sound and solar radiation is “wireless energy transfer.”

In the early to mid 1900’s the US had the world’s largest network of street cars. (Some smart person will relate the story of what happened.) These were electric vehicles that used transmitted power. Subways use a similar system. Many communities have studied the economic advantages and are returning to these systems although now wireless technology will probably be more in evidence. For most of the last 120 years this has not been considered a “dumb” technology.

If you didn’t manage to get past the picture, you guessed it (the photo is of a slot car track.) I didn’t get into the various technologies of wireless energy transfer in the article. All of them are … well wireless and slot cars use an actual connection like subways and trams. All of these technologies have a certain freedom from batteries. While electricity excels at being transmitted storage is not as easy. This is an essential advantage of an EV that doesn’t rely on storage.

Right. You use ultracapacitors and inductive charging. . .
