I was thinking more in terms of a small POET solar cell integrated into the single chip solution to power for example a remote surveillance camera processor and wireless connection.
I have often considered putting a camera mounted on a flag pole on my property. To keep an eye on such things as the pool for security reasons. The oldest boy used to have some pretty wild pool parties when he was a teenager. A surveillance camera would have definitely come in handy to keep an eye on things.
So imagine having something like this product replaced with something the size of a watch at very low cost?
