Make A Cheap &Easy Solar USB Charger With An Altoids Tin : TreeHugger - StumbleUpon Photos by Joshua Zimmerman The craftster behind the very popular $3 solar-powered emergency radio is back with a new awesome project: a cheap solar battery charger with a USB plug. Zimmerman wrote, saying that he saw a lot of small solar powered chargers being talked about over Earth Day, but there was a big problem: "They're all quite nice, but also quite expensive. I don't think I've seen any for less than $60, and I've not seen one that really suits my style." So, he came up with his own, using one of our favorite reusable items -- the ever wonderful Altoids tin. In looking for the cheapest way to accomplish the task, Zimmerman found that he could build a USB solar charger for under $30 (or $10 if be buys parts in bulk, though it's not likely you'll be buying bulk solar cells and DC-to-USB converter circuits). Zimmerman states, "The central brain of our project is a DC to USB converter circuit.
Scoprire lAcquaponica Domestica. Come Realizzare in Casa un Impianto per la Coltivazione Acquaponica. Soluzioni Possibili ma Soprattutto Low Cost! Se qui sei nuovo ISCRIVITI alle News RSS feed. Thanks for visiting! di Gaetano Benanti Da sempre mi sono interessato ai metodi di produzione di cibo non convenzionali, da buon appassionato di fantascienza il termine “coltura idroponica“ mi è sempre stato familiare, l’idea di una piccola serra a casa in cui coltivare le mie verdure tutto l’anno, senza utilizzare la madre terra come strato su cui far crescere le mie piantine, mi ha sempre intrigato e così ho fatto pure qualche piccolo esperimento e modestamente devo dire con discreti risultati. Trovando interessante l’argomento delle coltivazioni idroponiche o indoor, ho sempre frequentato siti e blog inerenti all’argomento, con il passare del tempo mi sono reso conto che questo metodo di coltivazione è tutt’altro che un giocattolo fantascientifico ma anzi un valido strumento di sviluppo economico e tecnologico.

NO ALLA DISCARICA DI AMIANTO! NO AL POLO LOGISTICO! Ri-Creazione.info - Riciclare in modo Creativo! Attrezzi di lavoro: la ciclofficina in casa In casa, con poco spazio, si può allestire una ciclofficina essenziale per poter intervenire sulla maggior parte dei componenti della bicicletta. Bastano un po' di attrezzi e una manciata di accessori. Cavalletto Un piccolo cavalletto per la casa può essere sufficiente, altrimenti bisognerà, per molte operazioni, ribaltare la bicicletta sottosopra poggiandola per terra. Chiavi a brugola Dimensioni utili: 2 mm 2,5 mm 3 mm 4 mm 5 mm 6 mm Pompa In casa si può tenere una pompa più grande per un gonfiaggio più rapido della camera d'aria, ma l'ideale sarebbe disporre di una pompa con manometro. Chiavi composte Dimensioni utili da 8 mm a 17 mm. Cacciaviti Almeno uno spaccato e uno a croce, meglio se di più dimensioni. Tiraraggi Per regolare i raggi o sostituirli. Smagliacatena Serve per interventi sulla catena e deve essere del tipo adatto alla catena usata. Leve per copertoni A casa è bene averne di tipo resistente, magari anche in metallo, per aiutarsi nell'estrazione dei copertoni. Kit per forature

Top 5 Exotic Free Energy Technologies From PESWiki Shortcut URL: See also News:Best Exotic Free Energy Technologiesand Tracking the Position of the Top 5and Directory:Best Exotic Clean Energy Technologies This page is devoted to featuring the top five exotic technologies that we know of that are closest to market. Here at PESWiki we cover the entire spectrum of clean energy technologies, from conventional methods such as solar, wind, geothermal, tide, wave, river on the one hand; to very unconventional or "exotic" technologies such as cold fusion, magnet motors, overunity electromagnetic motors, gravity motors, and vortex technologies on the other. There are many ways to harness the wheelwork of nature -- energy sources that the environment provides free for the taking -- that are not only clean but inexhaustible and ubiquitous. Conventional renewable energy (there are 25 genres) has made great strides but has limitations. Runners Up Spreadsheet Best Exotic Clean Energy Technologies In the News
Living Light Sculpture Reveals Air Quality of Seoul Check out how a retro glass sculpture maps the city’s air quality ! In the center of Seoul ’s Peace Park , which is located across from the Korean World Cup Stadium, lies a very extraordinary sight: an outdoor glass canopy called the Living Light Sculpture. Created by Soo-in Yang and David Benjamin of The Living , and commissioned by the Korean Ministry of Environment, this amazing sculpture is more than just a fantastic piece of art. It actually projects up-to-date information about surrounding cities and their air quality. The glass skin on the sculpture is a map that covers 27 local neighborhoods, and every 15 minutes certain sections light up to tell you which city has the best and worst air quality. The coolest thing about the sculpture is that you can send a text message of a certain area code to the Living Light Hotline, and then minutes later you’ll receive a reply back that tells you the area code’s air quality. digg
Pollution rise 'worsens' South Asia's winter smog 6 January 2012Last updated at 13:10 By Navin Singh Khadka Environment reporter, BBC News Experts say the smog problem is becoming increasingly serious A rapid rise in air pollution from fossil fuels and biomass burning has worsened winter smog and extended its duration in many parts of South Asia, scientists and officials have said. In Bangladesh, India and Nepal the temperature has plummeted and clouds of fog and smoke hang in the sky blocking sunlight for several days. Normal lives have been affected with many flights diverted and suspended and trains delayed because of low visibility. Experts say they have noticed that the intensity of smog has grown in the Indo-Gangetic plains in the last few years, leading to increased impacts. "Since 1990 onwards, there has been increase in the number of [smog-affected] days in northern India," says BP Yadav, director of the Indian Meteorological Department. "It is not a linear trend showing an increase every year. Continue reading the main story
Rhodia signe un contrat pour l'exploitation des Terres Rares à Madagascar (Boursier.com) — Rhodia, membre du Groupe Solvay a signé un accord avec le groupe allemand Tantalus Rare Earths AG "portant sur une coopération technique", afin de développer un procédé d'extraction et de purification des Terres Rares, ces minéraux indispensables à la fabrication de nombreux produits électriques et électroniques, dans une mine située au Nord-Ouest de Madagascar. Le potentiel d'oxydes de terres rares qu'il est possible d'extraire de cette mine est évaluée à 130 millions de tonnes, souligne Rhodia. Ces oxydes comporteraient par ailleurs "environ 20% de terres rares lourdes". Cette signature est une première étape vers un accord plus vaste pour un "approvisionnement exclusif à hauteur de 15.000 tonnes de terres rares par an". Rhodia n'en est pas à son premier coup d'essai dans le secteur des terres rares. Le groupe a déjà signé un accord en septembre 2011 avec China Rare Metals and Rare Earth Co., Ltd, filiale de Chinalco.
S’il va à Rio (le cas Schmidheiny) PREMIÈRE PARTIE Insupportable est un bien faible mot. Stephan Schmidheiny est l’héritier d’une famille suisse, parmi les plus riches. La transnationale Eternit était dans les souliers du Père Noël. Née en 1901, cette dernière fera fortune, immense fortune grâce à l’amiante (ici). 1901, c’est très proche de 1906, date à laquelle l’inspecteur du travail Denis Auribault écrit une note admirable (ici) sur la dangerosité de l’amiante. Eternit a compris autre chose. Vous pensez bien qu’il n’est pas venu recevoir son prix. La chose paraîtra incroyable aux Bisounours de l’écologie officielle, mais Schmidheiny a été le bras droit de Maurice Strong dans l’organisation du premier Sommet de la Terre de Rio, en 1992. Bref. Schmidheiny, le criminel de Turin, s’est depuis placé dans l’ombre. Comme cela tombe bien ! Il y a une suite, sous la forme d’un Appel à l’action, qui apparaîtra sous peu, chers amis lecteurs, sur Planète sans visa.
