Power Practical – a company that specializes in portable power and lighting – was started while founders, David Toledo and Paul Slusser, were sitting around a campfire. They realized that only a small fraction of the campfire's energy was keeping them warm and the rest disappeared into the sky. With backgrounds in material science engineering, this inspired them to find a way to do something useful with this wasted energy.
Boosted by investment funding from the Shark Tank’s Mark Cuban, Power Practical went on to design its best-selling Luminoodle. This flexible LED light string is waterproof and USB powered. Hang it from a tree, drape it over a tent, use it as a lantern or take sweet time-lapse photos. The opportunities are endless.
