The reporters didn't see a tear down of the sleeves, and wouldn't be able to identify a battery if they had. They showed sleeves and a charging indicator, rather than a simple wattmeter. This was a fraud—though like many inventors of perpetual motion machines, it is plausible Perry first fooled herself that the battery in the sleeve is just "to cover the initial surge" or "until we can fix this efficiency problem."
The important lesson here is that USA Today and similar papers can be fooled by a rigged demo and a sincere voice. Read the front page with similar skepticism!
- lern_too_spel 9y agoIt would require a lot of engineering work just to fake a demo to have a battery that charges when the sleeve is in the beam and doesn't when it isn't or the beam is blocked. More likely, there is actual power transmitted and received but not enough to charge the battery when the phone is doing anything at all. The charging indicator will turn on if you're putting 50 mW in, but that's not going to do much good when displaying the charging indicator uses more power than that.
