WEST LAFAYETTE, Ind. (WISH) — Indiana plans to rebuild a small section of highway that by next summer could charge electric vehicles being driven.
Purdue University and Indiana government’s Department of Transportation, in separate news releases issued Wednesday, touted the construction project as the first highway segment in the nation with wireless charging. Construction could begin as soon as April 1.
Neither Purdue or the Indiana Department of Transportation (INDOT) reported how much the project will cost.
Indianapolis-based White Construction was awarded a contract to build the wireless power-transfer technology in a quarter-mile of U.S. 231/U.S. 52 between Cumberland Avenue and Lindberg Road in West Lafayette. That’s near the Walmart Supercenter and the INDOT West Lafayette regional office.

Just like your Iphone charger.
I’m stuck here, but I’ve been advising others to not even THINK about moving here!
It’ll be RF energy.
The more cycles per second charges the battery faster.
That’s why military WWII aircraft equipment ran on 400 cps frequency.
I can just see it now. Well insulated sadistic cops pull people over and say “step out of the car.” Dancelarity ensues.
Additionally, one electrocution of someone standing outside their car and they'll be tearing out the copper to sell it to pay the lawsuits.
WOW!
At a quarter mile this is clearly a test/proof of concept. I have no problem testing the idea in the real world, and probably cheaper to use existing highway than to build a test track. You can close the road when testing (presumably at night) and cut the power when not testing.
Road is here:

It’s always a good idea ... until Pete Buttigieg accuses the highway of being racist ...
Sweden did install a slot car type system. Not sure how they expect to deal with snow and ice...it is Sweden after all.
“The more cycles per second charges the battery faster.

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.
Sadly yes math is based on the bell curve of human IQ and that is also racist.
But remember math is also universal when it humans survive long enough to get to the stars the language we will use to communicate with any other space capable beings will be mathematics almost assuredly binary based as it’s the foundation of all other forms of math.
BASIC is built on binary, so is HTML.
So in basic terms their the same?
Your hair might be a little frizzy after that quarter mile of charging
This proves it! Opportunities to “grift” taxpayers’ monies are unlimited! Who are the criminals who are coming up with this idiocy? This will work especially well in the cracked, pot-holed roads of Indiana where they puts tons of salt per foot in winter.
Hopefully no one wearing a pacemaker will drive that stretch of road.

No, they're not.
