New Camp Stove Goes Off the Grid
The stove burns wood but uses a thermoelectric generator to run a fan that makes the fire ultra efficient. Think of it like a miniature blast furnace. The electrical energy can also be used to charge small electrical appliances- like a phone or MP3 player.
Weighing only 33 ounces the makers claim a liter of water can be brought to a boil in only 4 1/2 minutes using less than 2 ounces of wood. A home version is also in the works.
