So you provide a video of Dave showing the math that you can get only microwatts out of radio waves to debunk something that ... claims to provide power in the microwatts range?

The "charge a phone" thing is obviously bunk, but that's not what's discussed here.

Show me applications in microwatt range to justify the "usable", moreover you need a wifi. Why someone should use that instead of a solar cell, like the one on calculators ?
