A way to charge your GoPro whilst simply hiking to the next spot.

Sole Power Tech is a company that makes energy from your energy.. They have created a product that generates power from a small magnetic rotor in the sole of your shoe and stores it in a small battery pack, with a 15 mile trek storing enough energy to charge your smartphone. They will be selling the soles soon and I think they would be great for trekking and charging your GoPro and headlamp for multi day adventures. Also since it's all incorporated into the sole you can change it between your running shoes and trekking boots.
