Solar Fire : Des concentrateurs solaires puissants, simples et peu coûteux. A propos du projet Éditer Le but est de contribuer à renforcer l'autonomie et la démocratie en proposant un accès libre à une source d'énergie puissante.
Nos concentrateurs produisent de l'énergie thermique sous forme de vapeur (avec la Sun Steam Machine P32 - concentration verticale) ou par un four (Sun Oven Helios - concentration horizontale). Les concentrateurs Solar Fire ne sont pas brevetés. C'est une technologie simple à construire avec des matériaux locaux (fer, boulons, miroirs). En quoi ce projet est-il singulier et créatif ?
C'est un projet d'accès à l'énergie en accès libre (open source). Les plans sont en accès libre, les guides de construction téléchargeables en ligne gratuitement, il y a aussi un programme pour définir la taille et l'orientation des miroirs. Il y a 3 entrées dans ce projet qui correspondent à 3 utilisation possible des concentrateurs : - les bricoleurs - les collectivités, fermes, villages et petites industries - une plus large production 1. 2. 3. 4.

This is the coolest thing I have ever seen It’s a series of experiments in tracking solar-concentrators.
Art for Art’s sake I think… despite the graphs and things I doubt this is more efficient than simply covering the same area with solar-electric cells… though it certainly looks cooler Loads more photos here. Concentrateur solaire - Résultats LinuxMint Yahoo France de la recherche d. Pascucci Media - Ballon solaire. Juillet 1, 2011 at 4:23pmhome La société «Cool Earth Solar» a dévelopé une technologie solaire déstinée à répondre aux contraintes de la crise énergétique mondiale.
Une technologie facile à mettre en place et réduisant parallèlement le coût de cette énergie.La technologie est basée sur des ballons concentrateurs de rayons solaires, d’autre part, les matériaux sont peu coûteux, ( le concentrateur+ le film plastique et l’air) sont choisis pour rendre la solution technologique économiquement compétitive tant sur la conception que sur l’entretien de ces centrales électriques.
En effet la surface réfléchissante est proche des couvertures de survies et l’enveloppe transparente pour le film plastique du ballon est du PET (polyéthylène téréphtalate) un polyester utilisé pour les emballages de la planète et pouvant donc être récupéré en masse. Cool Earth Solar develops inflatable solar concentrators to boost energy production. Solar concentrators are nothing new and researchers have long supported their use in an effort to increase the energy produced by a solar cell, without increasing the cost by much.
However, most solar concentrating systems rely on expensive infrastructure such as trackers and heavy mirrors that require specialized services for installation and maintenance. Cool Earth Solar is now trying to reduce the cost of solar concentrating systems by developing inflatable solar concentrators that are made using inexpensive and free materials. This unique design approach radically reduces material requirements as well as cost and time required to bring them to use. The solar concentrators are made using inflatable, tube-shaped plastic film similar to the one used commercially for packaging and shipping. Each inflatable tube, which is about 3 feet in diameter and 24 feet long, contains solar cells running across the length, either in a continuous strip or spaced six inches apart.
Cool Earth Solar. Our Inflated Solar Concentrator Solar Concentrators Focus the Sun.
Our inflated, tube-shaped concentrators are key to Cool Earth's innovative design. Each 3 foot diameter concentrator is made of plastic film - similar to that used commercially for packaging and shipping. When inflated with air, the concentrator naturally forms a shape that focuses or concentrates sunlight onto a PV cell placed at the focal point. This means we need fewer solar cells and other more expensive materials to produce a lot more electricity. The inflated structure is naturally strong—strong enough to support a person's weight—and aerodynamically stable, able to withstand high wind speeds. Each inflated concentrator includes, in addition to the solar cell receiver, a small air pump for maintaining air pressure and a simple heat sink to handle the concentrated energy from the sun.
A Support System Holds It All in Place. …And, That's It! All in all, a simple, elegant and cool solution.
