I have been thinking about different products and every once in a while, I wonder why someone does not innovate and create my version of a better mousetrap. If you have one of those "There ought to be ___________, please share it and let's see if someone can't possibly cobble one together that makes sense. I'll start this off by stating that I am very partial to crank flashlights. Headlamps are great because they leave your hands free to do whatever chore is at hand. Seems to me there ought to be a way to create some kind of crank mechanism to charge a headlamp, too. But when I envision a crank on the side of my head, that just gets way too silly way too fast. Perhaps some engineer/tinkerers have a better way to get closer to the kind of solution for a headlamp?
