It's apparently 90% efficient (which I believe - it can't be too inefficient otherwise it would generate too much heat to be usable).

A 10% efficiency drop takes electric cars from "much greener than ICE cars" to "still much greener than ICE cars".

In fact if this tech encourages 11% more people to buy electric cars then it might be more green overall. So take your poorly thought through naysaying elsewhere.

A device that only makes sense in extraordinarily high-end cars with an expensive adjustable suspension probably isn’t going to move the needle that much. If you’re doing object detection and moving the car, why not go a little farther and move a plug into a physical port on the base of the car, so you don’t need the car to move to the charger.

> why not go a little farther and move a plug into a physical port on the base of the car

Because that is not "a little farther", it's vastly more complicated. And also because the charging mat is flat, not some box in the middle of your garage.

This is clearly a better solution overall (for people who are too lazy to plug in a plug themselves).

> with an expensive adjustable suspension

It seems weird they took that approach vs having the box extend upwards when it detects that it should. Seems a lot simpler and cheaper.

It likely already had the active suspension anyway.

well, in this case it means you got extra 1.2 kW heater in your garage. and this is considering standard "slow charging" in ev world.

this amount of extra heat would probably need in car AC to kick in draining probably another 500W
