Camera that powers itself, solar power pixels:

It can record scenes forever with no batteries needed, except there needs to be light of some kind. As clever as this device is, it won't work in too dark a room.

An interesting concept, although I would think a separate solar panel would almost certainly be a better solution for real world applications.

Well, you would need more real estate for the solar stuff. At least you point and shoot and power at the same time.
