Arcosanti Coordinates: Arcosanti is an experimental town and molten bronze bell casting community that has been developed by the Italian-American architect, Paolo Soleri, who began construction in 1970 in central Arizona, 70 mi (110 km) north of Phoenix, at an elevation of 3,732 feet (1,130 meters). Using a concept he called arcology, he started the town to demonstrate how urban conditions could be improved while minimizing the destructive impact on the earth. He taught and influenced generations of architects and urban designers who studied and worked with him there to build the town. Overview[edit] DIY Skylights From Used Water Bottles Replace 50-Watt Bulbs Image via YouTube video An ingenious invention by an engineer in Brazil has made an enormous difference in his town. Simply placing a bottle of water in a hole in the ceiling can light up a room with the same brightness as a 50-watt light bulb! Residents have better lighting and are using less electricity. Check out how it works in the video.

Scientists Develop Affordable Solar Panels That Work In The Dark It's about damn time, don't you think? Scientists at Lawrence Berkeley National Laboratory announced Wednesday that they have been able to confirm a new high-efficiency solar cell design that utilizes nearly the entire solar spectrum. Translation: They figured out a way to make solar panels generate electricity in the dark. CleanTechnica says , In earlier trials, the researchers used different alloys that achieved full spectrum responses but involved very high production costs.

Turn Steel Into Solar Panels With Photovoltaic Spray Paint No, it's not a joke or a crazy awesome futuristic concept . It's real. Tata Steel Europe (formerly Corus) and Swansea University in Wales, UK are collaborating to develop a spray-on technology that would transform steel sheets into solar panels. Great earth house designd by Vetsch architektur Advertisement This is a great earth house designed by Vetsch architektur in a very special way as you can see from the picture. Lättenstrasse house is located in Dietikon, Switzerland and it has an amazing architecture. Hot solar cells are the cool way to water and power - tech - 14 April 2011 PUMPING water through micro-channels on the surface of a solar panel not only makes it more efficient but can also make seawater drinkable. Concentrated photovoltaic (CPV) cells use lenses to focus large areas of solar energy onto a relatively small section of photovoltaic material, so it is not surprising that they can reach temperatures of 120 °C. These high temperatures make the cells less efficient, reducing the amount of electricity they can produce. That is why keeping them cool is so important, says Bruno Michel, head of advanced thermal packaging at IBM's Zurich Research Laboratory in Switzerland. So with this in mind IBM has developed the "ultra-high concentrated PV", a hybrid solar panel that incorporates technology originally developed to help cool computer chips.

Photo Gallery Pat's First Cob (1998) This was Patrick's first cob project on his own after taking a one week workshop with Cob Cottage Company (CCC) in 1997. He built the foundation and then used beach logs for the frame. One Per Cent: Green Machine: solar street lamp feeds energy to the grid Helen Knight, technology reporter (Image: Adam Mørk/SunMast) The humble street light is joining the ranks of wind turbines and solar power plants in supplying renewable energy to the electricity grid. A street lamp covered in photovoltaic cells, which can generate more energy from sunlight than it consumes to light the street, is being tested in the UK.

Self-sufficient couple builds their own floating off-grid island (Video) From no-waste, no-impact, buy-nothing, no-money to living tiny, there are a multitude of saner and more courageous alternatives to the unthinking, zombie wastefulness of mainstream living. For Canadian couple Wayne Adams and Catherine King, living self-sufficiently meant building their own floating island near Tofino, British Columbia, consisting of twelve interconnected platforms that support their home, greenhouse, lighthouse and a dance studio. Wayne, a sculptor, and Catherine, a retired ballerina and carver, began building this extraordinary home back in 1992. They have dubbed it "Freedom Cove," and call it a "floating food garden." The two artists support themselves by selling their artworks in local shops and beyond, and supplement their income with veggies and fruit harvested throughout the year from their own garden, in addition to fishing. © Freedom Cove

Cheaper, Spray-On Solar Panels Could Appear in Three Years AUSTIN, TX — Researchers at the University of Texas have developed a method to create photovoltaic panels at one-tenth the cost of existing technologies using nanoparticle "inks" to generate electricity from the sun. The group, lead by Brian Korgel in the University's chemical engineering department, predicts that the technology, which would allow solar panels to be painted on rooftops or the sides of buildings, could be market-ready in three to five years. "The sun provides a nearly unlimited energy resource," Korgel said in a statement, "but existing solar energy harvesting technologies are prohibitively expensive and cannot compete with fossil fuels."
