This 3D-printed camp stove is extra-efficient and wind-resistant


I love camping, but there’s always an awkward period when you’ve left the tent but haven’t yet created coffee that I hate camping. It’s hard not to watch the pot not boil and not want to just go back to bed, but since the warm air escaped when I opened the tent it’s pointless! Anyway, the Swiss figured out a great way to boil water faster, and I want one of these sweet stoves now.

The PeakBoil stove comes from design students at ETH Zurich, who have clearly faced the same problems as myself. But since they actually camp in inclement weather, they also have to deal with wind blowing out the feeble flame of an ordinary gas burner.

Their attempt to improve on the design takes the controversial step of essentially installing a stovepipe inside the vessel and heating it from the inside out rather than from the bottom up. This has been used in lots of other situations to heat water but it’s the first time I’ve seen it in a camp stove.

By carefully configuring the gas nozzles and adding ripples to the wall of the heat pipe, PeakBoil “increases the contact area between the flame and the jug,” explained doctoral student and project leader Julian Ferchow in an ETH Zurich news release.

“That, plus the fact that the wall is very thin, makes heat transfer to the contents of the jug ideal,” added his colleague Patrick Beutler.
