Digital cameras have made photography much more sustainable, and rechargeable batteries are a great eco-advantage too. But photography is the art of light, so what better way to run your camera than on the power of the sun? This new solar strap from designer Weng Jie lets you do just that.

The Solar Camera Strap makes stopping to change batteries as “last year” as putting in a new roll of film. The only trouble, as Wired’s gadget lab notes, is that the straps feed directly into the battery port, making it impossible to have a battery in place as a back-up power supply. But as long as the sun’s out, you can keep firing with your camera securely around your neck, and it looks pretty nifty too.
