Scientists have created a self-powered camera that can take pictures indefinitely without any external power. Instead, it generates its own power using the light it captures with the sensor.
If flashlights can be solar and mechanically powered, why can't digital cameras? Turns out they can. Superheadz Japan has launched a new digital camera called the "Sun & Cloud." It's the world's first digital camera that's capable of generating its own power so that you don't need to constantly be worrying about battery drain and recharging.
