Le solaire à portée de tous July proving one of the coldest Coldest spot on Earth identified by satellite For more Latest and Breaking News Headlines SUBSCRIBE to The coldest place on Earth has been measured by satellite to be a bitter minus 93.2 Celsius (-135.8F). As one might expect, it is in the heart of Antarctica, and was recorded on 10 August, 2010. Researchers say it is a preliminary figure, and as they refine data from various space-borne thermal sensors it is quite likely they will determine an even colder figure by a degree or so. The previous record low of minus 89.2C was also measured in Antarctica. This occurred at the Russian Vostok base on 21 July, 1983. Fabriquer un panneau solaire thermique Fabriquer un panneau solaire thermique Mise à jour le 19 juillet 2011 Le prototype en phase de tests. · Contexte : L’énergie solaire en France comme dans de nombreuses régions du monde présente l’avantage d’être disponible gratuitement, durablement et de fournir une puissance non négligeable (850 watts par mètres carrés en moyenne sous nos latitudes par une journée bien ensoleillée). Cependant, il existe un autre type de panneau solaire moins cher à l’achat, et de surcroît réalisable aisément par tout bricoleur pour peu qu’il sache manier un marteau, une scie, et, éventuellement, une lampe à souder (petit chalumeau) de type « Camping Gaz ». Nous allons nous intéresser à la fabrication d’un panneau solaire de type thermique destiné à chauffer de l’eau ou tout autre liquide. · Principe de fonctionnement d'un panneau solaire thermique: Le principe du panneau solaire thermique qui n'a absolument rien à voir avec son homologue photovoltaïque et repose sur l'effet de serre. · Réalisation & photos:
Self Sufficient Living; Urban Homesteading, Small Scale Farming, Self Reliance Self sufficient living means learning to grow your own, make your own, sell your own and bake your own, for homesteading, urban homesteading or mini farms. Self reliance is the way forward. There is no better time to do this, especially with the presence of climate change, food safety, and the gloom of economic and political uncertainty. You don't want to be in a situation where you have the chance to take responsibility for your own destiny, but failed because you either didn't have the skills, or the inclination to make the change. I am all for turning lawns into lunch. Don't think you need a farm or homestead to be able to grow a couple of rows of vegetables and have a few nut and fruit trees. However, let's be realistic, it is almost impossible for people to be totally self-sufficient, however, this shouldn't put you off to make the effort to be as independent as much as possible.

Fabriquer un panneau solaire thermique pour moins de 5 euros Florida Outdoor Backyard Hydroponic Greenhouse Panneau Solaire en canettes Je vous présente aujourd’hui mon œuvre préférée. 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.
Grow hydroponic strawberries in your backyard | LED Grow Light Hydro Blog There are so many for whom maintaining a kitchen garden is a passion. If you are one of them, then you will understand the feeling of extra enthusiasm to experiment with new cultivation techniques and broaden the variety of plants and herbs in the kitchen garden. One of the best fruits for an after dinner dessert happen to be strawberries. Hydroponic Cultivation Technique If you are yet to catch up with the concept of hydroponic cultivation, here is a simple explanation to clarify the technique. Strawberry production and demand is expected to cross the the figure of 7 billion pounds by early 2012. Best Cultivation Time There is no definite time for cultivating hydroponic strawberries. Here is How You can Start…. Strawberry plants grown out of strawberry seeds take approximately 3 years to mature and start flowering. Post the harvest season, you can make new runners from your existing strawberry plants and chill them at a temperature ranging from 0º C to 4º C.

Living Off the Grid: How to Generate Your Own Electricity Our off the grid house near Anaconda, Montana Taking the Alternative Energy Plunge When my wife and I moved to Montana last year, we found a comfortable home on several acres with a view of the mountains. There was only one hitch – the house was off the grid. That doesn’t mean it was primitive. Solar panel with tracker Life Off the Grid The previous owner showed me the critical facilities and told me how to operate them. On our third night in the house, we went to bed as usual to the faint sound of wind outside, a sound we were already beginning to enjoy because it generated most of our power. Wind turbine I got up and went outside to check the power equipment. I had just learned the first lesson of wind and solar power: they can’t always be counted on when you need them. Battery bank Alternative Energy Cost Since then, I’ve learned the second lesson of renewable energy: while the energy may be free, it still costs more than electricity from a utility company.

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!
What Does Living Off The Grid Mean to You? - Living Off The Grid One thing I’ve noticed since starting this website is that there’s living off the grid and there’s Living Off The Grid. What do I mean by that? To me, at least when I first started writing about off grid topics, to “live off the grid” simply meant to have a home that wasn’t connected to the electricity grid. In other words, to have a battery backed-up solar, hydro or wind power system. But there is yet another definition to living off the grid: Being a ghost to the government. While this lifestyle is a bit too hardcore for me at this point in my life, I admit that I’m fascinated with the idea, and respectful of the people who choose to do so. With so many people going to Google and finding our website by typing “Living Off the Grid” or “How to Live Off The Grid” and even “How to Live Off The Land” – it makes me wonder what the intent was behind each search.
