[...] It’s not exactly wireless charging, where power is broadcast over the air, but it’s proximity power charging, where the devices need to get close enough to induce a charge through the short air space. Proximity charging most often uses magnetic induction, where two magnetic coils — one inside a charging pad and one inside a device — connect to allow a charge while the device is sitting on the pad (here’s 10 Things to Know About Wireless Charging).

Try that in a car park in the rain – a bit different. The pad can even be sealed over.

“Over the air” is not efficient and using charging pad is like using a normal charger, so I don’t see why so much fuss?

A single phase 2kW (delivered on the vehicle) IPT system was built early this year and demonstrated in May at the Electric Vehicle Symposium in Norway, and again in June at the first German Electric Vehicle Conference. The gap between the charging pad and underside of the car was greater than 200mm.

The system was developed by the Power Electronics Group at the University of Auckland in New Zealand and the many patents awarded over the last few decades are held by UniServices Ltd from which licenses are available …….

Most of it comes down to one thing: Cost efficiency.
Better materials, better manufacturing.

I bet if we found a planet made entirely out of platinum, we’d have a nice space program going already.

Faraday discovered electromagnetic induction. Wireless power over a considerable distance can’t be accomplished by electromagnetic induction.

Tesla discovered resonant induction, a concept more like radio transmission than electro induction.

So you might say… Marconi founded the basic princible of “long” distance power transmission. But oh! Wait! Marconi reverse engineered Tesla’s work, then claimed radio transmission as his own.

Ahhh hell, nevermind. Al Gore probably founded both fields.
