AIRPOWER: I wrote about AirPower’s absence earlier this week. What I’ve heard, third-hand but from multiple little birdies, is that AirPower really is well and truly fucked. Something about the multi-coil design getting too hot — way too hot. There are engineers who looked at AirPower’s design and said it could never work, thermally, and now those same engineers have that “told you so” smug look on their faces. Last year Apple was apparently swayed by arguments that they could figure out a way to make it not get hot. They were, clearly, wrong. I think they’ve either had to go completely back to the drawing board and start over with an entirely different design, or they’ve decided to give up and they just don’t want to say so.
From Apple, via TechCrunch’s Matthew Panzarino:
“After much effort, we’ve concluded AirPower will not achieve our high standards and we have cancelled the project. We apologize to those customers who were looking forward to this launch. We continue to believe that the future is wireless and are committed to push the wireless experience forward,” said Dan Riccio, Apple’s senior vice president of Hardware Engineering in an emailed statement today.
My take: This whole field was more exciting when analysts were talking about over-the-air charging from a distance of up to 15 feet. Whatever happened to that idea? Meanwhile, I got tired of waiting for Apple and bought two third-party charging disks. They work just fine, no overheating.
