7.4mW is more power than I would have thought possible. That is really cool. Plus with some additional hackery you may be able harvest up to double by toggling the second audio channel on and off when you don't need to receive data from the phone. I'm going to put together a board based on their specs. If anyone in the bay area is interested in collaborating on a project with it shoot me an email.
