Disposable Rocket Stove Keeps You Fueled In The Wild

Don’t know about you, but we can’t start the day without coffee and a shower. If you were to drag us on some overnight trip into the wilderness, we could probably forego the shower for a day, but we will be a grumpy trail mate without some kind coffee, even instant.

Yes, if you were to get us on an overnight outdoor adventure, we would insist on bringing along a couple of these little disposable, self-destructing rocket stoves, if for no other reason than that we can have some coffee without having to forage for a bunch of firewood and build a whole regular-sized campfire. Don’t worry — we’ll share the water because there’s plenty of time built in. Per [smogdog], these Swedish torches will boil water in 20 minutes and burn for 60 — that’s enough time to make a coffee, a bowl of soup, and toast a single marshmallow before the fire consumes the scrap wood.

We love the use of bike chain as a burner to raise up the pot for fire ventilation. But our favorite bit has to be the dual-purpose packaging. It’s nice-looking, it’s informative, and it’s paper, so you can use it as a fire starter. Failing that, [smogdog] has a backup fire starter system — rubbing alcohol in a small spray bottle. Unwrap a protein bar and check out the demo video after the break.

Tired of the same old, boring trail foods? How about flat-pack pasta that morphs into fun shapes when you boil it?

Tea Making The Mechanical Way

For some of those who are aficionados of the drink, tea making can be serious business. For them, strong, black, leaf tea left for ages to stew in a stained teapot that would strip the hairs off your chest (like it should be made) just won’t do. These beverage anarchists demand a preparation process of careful temperature regulation and timing, and for some reason repeatedly dunking a teabag in the water.

For them, [Dorian Damon] has an automated solution to getting the crucial dunking process right. He’s made an automatic tea bag dunker. The teabag is mounted on a slide operated by a crank, and the crank is driven through a pair of bicycle hubs. Motive power comes from a mains shaded-pole motor, an unusual bi-directional one of which he only uses one side. He measured his personal dunking rate at about 50 per minute, so he only needed a 4:1 reduction to match the motor at 200 RPM.

The resulting machine will happily dunk his tea bag at that rate for as long as it’s left switched on. He’s put a few videos up, of which we’ve posted one below the break.
