gotwind.org - DIY Renewable Energy Resource 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. Par exemple, les gigantesques profits générés par les monopoles sur les réserves stratégiques de pétrole. 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. ATTENTION! ATTENTION!
Greenhorns - To Promote, Recruit and Support New Farmers in America Solar Panels Compared What is the best solar cell you can buy? It all depends on what is important to you. Two things that can be important are cost and size. For applications where space doesn't matter (like putting panels in your back yard or on your roof), you want to make the most power for the least cost. Here is what I've found... Solar Panels ranked by least cost per unit of power (best first) Clearly, large panels bought in bulk are more economical. For mobile applications (solar powered cell phone or lawn mower), you want the most power per unit of area. Solar Panels ranked by minimum size per unit of power (best first) Interestingly, some efficient panels are also economical. Please note that I am basing these lists on the data supplied by the referenced web pages. Q: Why didn't you include X? A: If you know about an interesting panel that is commercially available and not included here, send me a link where I can see its specs and actually buy it and I will add it to the list. A: I agree.

Magenn Power Inc. - Home How To Build Cheap WINDBELT Generator using VHS tape picture 10 picture 11 The Key Advantages of Windbelt over existing micro-wind turbine technology is not only the cost but simplicity and also the fact that it is good at taking power from turbulent wind flows, i.e. in a built up domestic setting, and it is also very quiet in operation. Unlike PV solar panels, wind turbine generators do not scale down so well. While large wind turbines can generate huge quantities of electricity very efficiently and relatively cheaply, as the size of the wind turbine is reduced, efficiency reduces and cost per generated watt jumps quite enormously. Wind-belt is an ultra efficient and mechanically very simple wind generator alternative. Its cheap components can be bought almost anywhere in the world. Larger DIY versions of the wind-belt are possible, but in such case the problem of noise emerges.
