Solar camera strap
The modern DSLR requires so little power that, unaccustomed to the habit, you can forget to charge its battery. But this concept by Weng Jie would solve the problem. It's simply a camera strap with solar paneling.
This strap would be more useful as DSLRs require less power. But on top of that, the solar rig here has a lot more surface area (I'm guessing double or triple) than that of your average pocket solar adapter.
