Rocket Mass Heater Book - -Our newest edition- - | Cob Cottage Company More than a second edition to the groundbreaking Rocket Stoves to Heat Cob Buildings, the new book Rocket Mass Heaters, Superefficient Woodstoves You Can Build (And Snuggle Up To) is the most comprehensive book available on the subject of Rocket Stoves. Here's a superefficient wood fired heater you can build for yourself in a weekend for less than a hundred dollars. This book explains in detail exactly how to build one, then how to use it in a range of applications. We discuss materials, where to find them, what to pay and how to make use of found and recycled parts. The section on fire and fuels is thorough but simple, we tried to keep away from numbers whenever possible. There are success stories, case studies, references and where to find further information, all heavily illustrated and with four full pages of color photographs. New woodstoves are no longer craftsman-made locally. To order, please visit the Cob Cottage Company products page.
Amazing low-tech harvester collects water from even the driest of air Even in places where there’s a severe lack of water, there’s one thing every place has. Air. And even in the most arid of climes, there’s moisture in the air, even if it’s not enough to be felt on your skin. With a deceptively modest design, Airdrop filters hot environmental air through a turbine, feeding it through a copper tubing system—with copper wool to maximize surface area—and into the earth where it cools and releases moisture. Okay, that’s just genius and badass. Via I Love Cob! ∞ Construction of a Rocket Stove View photos here » I experimented with the plans that Ianto Evans and Leslie Jackson prescribed in the first draft of ‘Rocket Stoves to Heat Cob Buildings: How to Build a Super Efficient Wood Fired Heater‘. I gotta tell you that it didn’t sink in the first time I read it. I understood it in principle, but it just seemed counter intuitive. The smoke goes down instead of up? Every time I’ve seen fire and smoke it goes up. The rocket stove is a efficient wood burning device. The rocket stove is a down-draft heater. Updates: Here is a of Ianto’s Rocket Stove book. Read a review by Ocean Liff-Anderson at Dirt Cheap Builder. The second edition, Rocket Mass Heaters-Superefficient Woodstoves You Can Build (and snuggle up to) is available here:
Charge your cellphone with a Plant!! | Service Design Master Who hasn’t been in a situation where they really need to use their phone to find any address or make an important call only to find out it turned off because it didn’t have any more battery. With the irruption of smartphones, mobile internet and all the apps that we constantly use, the cellphone battery doesn’t exceed the 8 hours duration. A similar situation was the kick-off for an idea that can change our energy sources and be a real step forward for the World Science. “You ran out of battery again? If only we could get power (energy) from plants… “, This was the thought three friends had on the University campus. Evelyn Aravena, Camila Rupcich and Carolina Guerrero, who after this, started to research and see how viable this idea was: “there are no sockets, but there are plenty of trees…” After three years of arduous research, they succeeded in their mission and the result was E-Kaia, energy of the Earth in Greek.
