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?
Via which mechanism exactly?
The ones I have at home get it through the tracks.
Which are just heavy gauge wires.
Third rail, baby
Which is a wire.
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.
