Electromagnetic induction gets rid of cables
https://www.economist.com/news/scien...actical-refuelA WISE driver keeps an eye on the fuel gauge, to make timely stops at filling stations. For drivers of electric cars, though, those stations are few and far between. The infrastructure needed for refilling batteries has yet to be developed, and the technology which that infrastructure will use is still up for grabs. Most electric cars are fitted with plugs. But plugs and their associated cables and charging points bring problems. The cables are trip hazards. The charging points add to street clutter. And the copper wire involved is an invitation to thieves. Many engineers would therefore like to develop a second way of charging electric vehicles—one that is wireless and can thus be buried underground.
Electrical induction, the underlying principle behind wireless charging, was discovered by Michael Faraday in 1831, and is widely used in things such as electric motors and generators. Faraday observed that moving a conductor through a magnetic field induced a current in that conductor. Subsequent investigations showed that this also works if the conductor is stationary and the magnetic field is moving. Since electric currents generate magnetic fields, and if the current alternates so does the field, an alternating current creates a field that is continuously moving. This means that running such a current through a conductor will induce a similar current in another, nearby, conductor. That induced current can then be used for whatever purpose an engineer chooses.
FWIW.

Another expense only a small handfull of people can pay.
The amount of EMI involved in that type of setup would render most electronic devices useless. Try putting your smartphone next to a large 3 phase motor.
no doubt about it. the emf output would have to be tremendous.
Just because of tripping on cables we want to park over a coil?
The process described sends energy in many directions.
Cant see how this is efficient compared to hooking up a cable.
In a house I can see the advantage of not having to wire everything, but for a car driving to "fill up"?
More info required.
Said the same thing about computers I bet.
Repugs just killed the non-luxury EV market by killing the $7500 Fed credit. BigOil is thrilled.
Snowflakes like you need to stop with your pathetic en lement mentality.
