Made for extreme outdoor conditions, the Peakboil stove doesn’t only work in the harshest of winds, it actually is optimized to boil your liquids faster than usual. Designed by the students at ETH Zurich, the Peakboil is a 3D printed stove and jug with a specially designed burner and chimney system. A series of Venturi nozzles on the burner use localized pressure differentials to feed the flames inside the combustion chamber, which is protected from wind by high sides and a narrow top chimney. The stylized chimney walls increase the surface area, allowing more heat to be provided to the liquid within the container, increasing its temperature substantially faster than a regular stove and kettle.
The entire jug and burner system are 3D printed, to achieve their specialized design. The complex, single-piece combustion chamber couldn’t be manufactured using conventional techniques, and is only possible via additive manufacturing. Selective laser melting was used to fuse metal powder together in layers just 1/30th of a millimeter thick, and to progressively create 3D details from scratch.
