As an avid camper and technology enthusiast, I was very excited to learn about BioLite’s efforts to bring eco-friendly technology to the outdoors when we visited the Maker Faire in New York last month. BioLite is a tech company with a vision: their slogan “energy everywhere” couldn’t be more succinct: their main product is the BioLite CampStove which is an economic, lightweight stove powered by small sticks and kindling. The device uses what I call a thermoelectric energy loop: the heat from the flame passes through a thermoelectric generator (TEG), which in turn powers a fan that stokes the flame. Those familiar with thermodynamics might find that counterintuitive, but it’s the kindling that fuels the system. The fan combined with the shape and structure of the stove turbo-charge the heat while containing most of the smoke. The icing on the cake is that the CampStove can power/charge electronic devices through a USB connection on its side using extra power generated from the TEG!
