Detroit is now home to the country’s first chunk of road that can wirelessly charge an electric vehicle (EV), whether it’s parked or moving.
Why it matters: Wireless charging on an electrified roadway could remove one of the biggest hassles of owning an EV: the need to stop and plug in regularly.
You know what other form of transportation wirelessly recieves power? Trains.
Wirelessly?
Not wireless. Overhead contact lines are wires they just skim along them.
Comparison for this would be a metal brush dragging the ground over electrical contacts to maintain connection. Which would be a third rail on roads, very dangerous.
Guess what’s inside your wireless charging port!
The point is, there’s no physical connection being made.
… Yes there is in trains. Not in wireless charging. I was correcting your comparison.
Electric trains gather energy by running a conductive element along suspended wires. No connection made.
Wireless chargers charge devices through induction, in which a coil of wire produces a magnetic field, inducing a current in the wire coil in your device. Both have wires, neither make connections, we call both wireless.
Via which mechanism exactly?
The ones I have at home get it through the tracks.
Which are just heavy gauge wires.
Gooooood point
Third rail, baby
Which is a wire.
