One of the worst things that could happen on a photo shoot is that your camera runs out of juice and you don't have a spare battery. It's not so bad if your shooter is powered by the easily available AA-size cells. However, most dSLRs and point-and-shoots employ a lithium ion pack that needs an electrical outlet to be recharged.
But if the Solar Camera Strap makes its way to stores anytime soon, you'd never have to worry about your camera running out of power again. Designer Weng Jie conceptualized a row of solar panels on the strap, which can be hooked up on the shooter so you can recharge the snapper whenever you're shooting under the sun.
For now, the Solar Camera Strap is only a concept, albeit a great one. Hopefully, it gets commercialized soon and ends the days of photographers cursing halfway through a shoot when the battery runs dry.
