I actually forgot all about that. I had read a large and very nerdy article on this recently. The reason why this hasn't taken off is because its not really practical or efficient to charge a phone with the dynamo. Most phones have software that throttle low level charges like what you would get from a dynamo. I have been becoming a big fan of battery lights as well. They have so many lighting options and stay charged for a really long time. And battery packs are really easy to keep with you if you go longer. Easier than all of the wires and drag that a dynamo brings. BUT there is something to be said to always 100% having a light read to go if you need it.
