A Practical Zeer Pot (evaporative cooler / non-electrical refrigerator) A zeer pot is an evaporative cooler used in rural Africa and the Middle East to keep vegetables fresh. They consist of two terra cotta pots, one nested inside the other, with the gap between them filled with wet sand. The sand serves as a thermal mass that helps keep the pot cold once it has cooled down, and acts as a wick to spread the moisture up the walls of the pot. Unless the air is very dry and the pot is exposed to a constant breeze, they generally do not become as cold as a refrigerator, but they will keep vegetables fresh for a couple of weeks. Think of it as an open-cycle refrigerator. Zeer pots were re-discovered and popularized in the early 2000s by the Nigerian teacher Mohammed Bah Abba. In the under-developed parts of Africa and the Middle East, zeer pots use custom made pots prepared by local potters. What makes this zeer pot practical? There are other zeer pot instructables out there, but this one is optimized for practicality. Parts list with prices
Panneau Solaire :: Panneau de chauffage solaire fait en canettes Il est en réalité incroyablement simple et économique de construire un chauffage solaire d'appoint pour sa maison. Le plus intéressant est que le système d'accumulation de la chaleur est construit a partir de canettes en aluminium vides! Plusieurs facteurs font qu'entre les énergies renouvelables (et écologiques), et les énergies conventionnelles (non renouvelables et non écologiques), le choix qui s'impose est d'abord celui de l'énergie conventionnelle avec pour argument principal le prix. Le chauffage solaire est construit a l'intérieur d'un cadre en bois (contre-plaqué 15mm), d'une plaque de Plexiglas / polycarbonate de 3mm. Le panneau solaire est fabriqué a partir de canettes de bière et de soda et couvertes d'une peinture noire résistante aux hautes températures. Pour commencer, il faut récupérer des canettes vides qui seront le coeur de notre système. Sur le fond de chaque canette, on fait 3 trous avec un pointeau (Photo 2 et 3). ATTENTION! N'enlevez pas les débris a main nues!

ParaCord Survival/Rescue Belt The project described on this page is relatively easy, yet produces a usable and effective survival/rescue belt. My Paracord Survival/Rescue Belt concept is based on extremely fast cord removal if needed. If you ever find yourself in need of a rescue line, you can get about 50 feet of line within seconds from this belt. Note: My pictures show the belt very short so it'll fit on your screen! This belt is very simple to make.

About - Emily Cummins When I was four, my Grandad gave me a hammer and began to teach me how to make toys from scraps of materials found in his garden shed. I loved the fact that we could make something out of seemingly random bits, and my interest in sustainable design was born. As I got older I learnt about the properties of different materials and became more experienced in using a range of tools. Now I'm 27 and my latest innovation is a sustainable fridge which is 'powered' by dirty water but keeps medicines or small food items clean, dry and cool. I refined my fridge during a gap year in Namibia and then decided to give away the design plans in townships across southern Africa because I wanted to enable as many people as possible to build their own fridges. My design philosophy involves a back-to-basics approach which keeps an eye on the past as well as the future and combines the best of both.

C’est un capteur solaire thermique à air. Je me suis inspiré d’américains qui réalisent et commercialisent des panneaux fabriqués avec des canettes recyclées. C’est ici que ça se trouve : Ils vendent ça 2700$, donc je me suis dit que je pouvais essayer de le fabriquer moi-même (et si possible de l’améliorer). Les canettes sont percées et assemblées en colonnes dans lesquelles l’air circule et se réchauffe quand il y a du soleil. Le principe (en rapide), c’est que le panneau est posé sur un mur orienté Sud (la position verticale est idéale pour l’hiver car le soleil est bas dans le ciel) et dès que le soleil se montre, l’intérieur du panneau surchauffe (effet de serre : les canettes sont peintes en noir et le caisson isolé et la vitre empêche la chaleur de ressortir). Petite photo du panneau : Fabrication : Le plus long, c’est la préparation des canettes : il faut d’abord les collecter puis les laver et les percer.
How to Build a Clean Fire: The Top-Down Fire Living Published on November 24th, 2011 | by ziggy There’s more than one way to skin a cat, and there’s more than one way to build a fire. But that doesn’t mean they are all equal: the top-down fire (or upside down fire) is perhaps the most efficient and cleanest way to build a fire. You can use this method when you build a fire in your small wood stove, your big wood furace, at a campsite, or basically any place you would have reason to burn wood. How to Build a Clean, Top-Down Fire Remember all of those smoky attempts at getting a fire going during those camping trips? The top-down fire is basically the exact opposite of that mess: a bed of bigger logs, with smaller wood placed atop that, and kindling and paper at the top, where the fire is lit, and then burns down the pile. A top-down fire is superior in that it is much more clean-burning than any other type of fire building. The more technical reasons why top-down fires are cleaner burning can be read here.
