Get the Biolite CampStove that Hurricane Sandy survivors used - heats, cooks, and generates electricity - Wilderness Arena Survival
This little device really took off in New York when Hurricane Sandy survivors discovered it provided heat, boiled water, and allowed them to jack in to its USB port to charge their smartphone devices. The Biolite CampStove sells for $129 and runs off of any renewable biomass such as twigs, wood scraps, even pinecones - all without generating any smoke. It is about the size of a water bottle (8 inches by 5 inches) and weighs only 33 ounces. The stove will boil 1 liter of water in 4.5 minutes and its built-in thermoelectric generator outputs from 3.4kW to 5.5kW to provide up to 4 watts for charging USB chargeable devices. Biolite says 20 minutes of charge time provides 60 minutes of talk time which is pretty good for an in-the-field charger.
