Chimney camp stove: boil water with sticks and grass
CAMPING -- "Fire. Air. Wood. Water. Those are the essential ingredients for the Backcountry Boiler, an esoteric stove-type product called 'the world’s first ultralight chimney kettle.' " says The Gear Junkie Stephen Regenold.
The product is made in Pittsburgh, and the stove is marketed to ultra-light backpackers and other wilderness types in need of hot water in the backcountry with little fuss.
Check out The Gear Junkie's review.
Note: The Backcountry Boiler is featured on Kickstarter, a fundraising website. The company has a goal to raise $20,000 to fund a redesign and to expand distribution to needy countries where use of the stove can reduce deforestation. More than $13,000 has been raised at this writing. See here for more details.
