’Eternal’ camera can take pictures forever

A camera powered by the light it uses to take pictures has been invented by American scientists.

The camera generates power by converting some of the light falling on its sensor into electricity that is then used to take a snap.

Theoretically the self-powered device could take a picture every second, forever.

The camera’s creators are now refining the device and are looking into ways to commercialise the technology.

…even at night?

One of the devices in the James May’s Big Ideas video was a solar powered car. He drove a solar-powered car at night under artificial light, for the purposes of measuring energy conversion efficiency. So if artificial lights at night can do that, then they’d have no trouble allowing a solar-powered camera to snap photos at night.

> Prof Nayar managed to create a photodiode that combined the light-sensing abilities of a camera with the power-converting properties seen in solar panels.

That’s the nice bit. Convergent technology.

and how long can we produce artificial light at night? Have we fully evolved to cope with all that?

This is a silly name. There’s nothing eternal about it. It is photoelectrically powered, is all.

I agree.
