This video camera is powered by light

That's the elegant solution I love about welding equipment. They realized hrm super bright light source.... lets use solar cells. Need just enough power in battery form to keep the micro alive. Been doing it since way back in the '90s.

As we go increasingly wireless, we become keenly aware of recharging batteries. Consequence is greater interest in "ambient power harvesting". A device powered by its own sensor's energy input is insightful. What next? keyboards powered by typing? trackpad/mouse by clicking & movement? Screens with an extra sub-pixel for light collection? Smart watch "self-winding"?

Combine this with the recent millimeter scale computer motes <a href="http:&#x2F;&#x2F;robotics.eecs.berkeley.edu&#x2F;~pister&#x2F;SmartDust&#x2F;" rel="nofollow">http:&#x2F;&#x2F;robotics.eecs.berkeley.edu&#x2F;~pister&#x2F;SmartDust&#x2F;</a> and we get real close to several sci-fi themes such as optical camouflage and universal panopticon.

This is very interesting!<p>&quot;it could lead to a fully self-powered solid-state image sensor that produces a useful resolution and framerate&quot;<p>In this case would it be able to output colors?

Can it also be used to power other electronics attached to it, such as a CPU?
