I'm sure they could attempt to pass cost on to customers in a setting like a Starbucks. But they could only do so by raising costs of their coffee, drinks, and baked goods. They can't really charge you for taking advantage of something they broadcast unless they can find a way to encrypt or monitor how much of that you actually harness.

It would be a cool idea though. Having a device that whenever inside a car, or a coffee shop, at your cubible or in your home charges itself just by *being* there.
