“The more cycles per second charges the battery faster.

That’s why military WWII aircraft equipment ran on 400 cps frequency.”

This will need to be in the tens of kilohertz range with a air gap of 17cm the size of the coils and gap are proportional to the frequency the emf field forms and collapses per second.

Military and civilian aircraft use 400hz because the transformers are 8 times smaller than a equal power 60hz and motors are ten times smaller by mass.

Perfect example is the largest jet turbine in the world hangs off the wings of the 777 it’s inlet is the same size as the 737 fuselage. The integrated power generator is about the size of a one horsepower 60hz induction motor and that includes the CVT gears for the two pole generator. A person can hold the whole unit two of which power the whole plane. Those little units put out 170kva that’s 239hp impressive for such a small unit size. How do they do it? High rpm and only two poles so it’s 24,000 rpm for 400hz. Generator output is logarithmic related to the number of times the poles cut the EMF field windings the more cuts per second the higher the output for a given frequency in this case 400hz you could use 4 or 8 poles like older 400hz generator use and drive them at 12,000 or 6000 rpm they would scale up in size logarithmic in size and mass.

Math is racist.

Hopefully no one wearing a pacemaker will drive that stretch of road.

Possibly, Elon Musk could build space satellites to aim solar-powered proton beams precisely enough to power moving vehicles, technically naked hydrogen power on demand. But the first customer of such a technology would obviously be the military, to blast things, or maybe sterilize whole civilian populations, over a few milliseconds, from space.
