Game changer for smart watches if this turns out to work and scale well

It would be nice for car keys and other remotes to never run out of battery. This seems like a good convenience technology, assuming it can be brought to market at comparable prices to li ion cells.

Big, big if. It says nothing about the actual manufacturing process. Also, the kind of movements smart watches make are large enough I'm guessing a balance of some kind already can capture a lot of it, if you don't mind the feeling of having weights on your wrist.
