Discussion: Self-powered camera trap

Back in April I read about this project out of Columbia University for a self-powered camera that uses the light hitting the sensor to power the camera. It's a cool idea, and could really improve the effectiveness of cameras deployed in the field. I'd be especially interested for this technology to be coupled with a mesh network so that an array of these devices could be placed throughout an area, and the images could be received and processed in near-real-time. The Buckeye Cam has wireless image transfer, but it's still too big and expensive to be a game-changer, in my opinion.
