I remember reading an article a long time ago about obscure technologies that could revolutionize the future, and one of them was wearable jewelry that could generate electricity, with the idea that it could be collected into a grid through the shoes of the people wearing it. My idea is a little less invasive on the body. My idea is a suit or set of items that can generate electricity to charge a wearable battery pack, that could then charge mobile devices. The most obvious solution would be a means of harvesting energy from walking, but the jewelry I saw could also harvest from arm movements and even blinking. I would like to see what Ben and the crew could come up with.
