You're equating difficulties with impossibilities. The analogy of a small power generator holds even if it's the power that's small not the generator.
Looking back at your original post, I was simply saying that "you can't even run an LED on this" does not mean it's useless, and you may be able to scale it up. So I think we violently agree about the difficulty. I do see how my comment may have made someone think I meant that this could actually be used in phones as is. I mistakenly used phones as an analogous device.
