I once came up with an idea where you have a flashlight that you don't need to worry about batteries with. You can just put it in a backpack or whatever, and when its time you need it, whip it out and it runs off solar power. No batteries or capacitors needed. Just a light bulb hooked to a solar panel. I overlooked the main flaw in this idea. Your idea is much better. I wished I hadnt spent $1000 patenting this solar powered flashlight.

Just kidding. But the idea is pretty good, although it is kinda annoying just trying to pull out one servo plug, let alone a bunch.
