Biodynamic Farm Powers More Than Plants with Sun


Tani Creek Farm in the Pacific Northwest uses sunlight for more than just growing vegetables. In the misty hills of Bainbridge Island, across Puget Sound from Seattle, Washington, a 25-acre biodynamic farm uses solar power for all its agricultural needs such as irrigation, water movement (pumped from ponds to other uses) and food production, as well as for residential purposes. Contrary to popular belief, solar power in the cloudy Pacific Northwest - where Bainbridge is located - is a viable energy alternative to fossil fuels according to solar contractor Jeff Collum of Sound Power. The farm's 29-kilowatt system covers two outbuildings and are part of the owner's mission to create a self-sustaining farm that uses clean energy.

California Dreamin' at Claire's Bakery

A San Diego, California, business carried its mission of serving up organic treats and coffee to a higher level. Claire's on Cedros  went for a full-on sustainability assault on site development, water use and energy efficiency of its entire operation. The result is a LEED Platinum-certified suite of small buildings that includes solar panels doubling as carports and awnings to provide shading. http://www.solaripedia.com/13/226/California+Dreamin%E2%80%99+at+Claire%E2%80%99s+Bakery.html

Largest US Solar Farm Soaks up Sun in Florida


And produces 25 megawatts of electricity! This $150 million plant came in $22.5 million under budget and took just 10 months to build - several months ahead of schedule. Its 92,000 solar panels can withstand 130-mph winds. The Desoto Solar Farm is built to last at least 30 years, and it will take from 25 to 30 years for Florida Power & Light, the owner, to recoup its investment. Construction of this facility also created 400 jobs!  http://www.solaripedia.com/13/180/florida_sun_powers_largest_us_solar_farm.html

Open PV Database Tracks US Solar Installations


The Open PV Project is a community-driven database, fostered by the National Renewable Energy Laboratory, of photovoltaic (PV) installations around the US. It collects, organizes and distributes info on location, size, cost and date of every PV installation in the USA. A very cool animation is superimposed on a US map showing all logged PV systems installed since 1998.

Recycling Solar PV Panels


In its whitepaper "Toward a Just and Sustainable Solar Energy Coalition" the Silicon Valley Toxics Coalition (SVTC) argues that for solar to be truly green, industry must reduce and eventually eliminate the use of toxic materials and develop environmentally sustainable practices.

Wineries and Thieves Go Solar in California


Solar energy is hot, according to Mike Treleven reporting in the Napa Valley Register (27 November 2009). Not just with wineries attempting to lessen their carbon footprints — but also with thieves. Numerous Napa Valley wineries have been victimized by thieves lurking in the night and stealing their solar arrays. A single panel is worth about $1,000, measures two feet by three feet and weighs around 35 pounds. Between June 2008 and late September 2009, Napa County saw 14 solar thefts and two attempted thefts. Of the 14 thefts, two were in the city of Napa and the rest were at wineries around the valley, Napa County Sheriff’s Capt. Tracey Stuart. More than 400 panels, worth about $400,000, have been stolen.

Wheelchair Accessible Treehouse Uses Solar


Camp Twin Lakes wheelchair-accessible treehouse features a solar array, a vegetated roof and composting toilets in Georgia, USA. A 1.4-kilowatt, eight-module photovoltaic solar array is mounted on a nearby pole and supplies the treehouse fans and misting system pump with DC power.

Solar Electric Sails in Space


For interstellar travel, light-sail craft would depend on extremely large-scale constructions such as huge solar-power relays around Mercury and enormous Fresnel zones in the outer Solar System. Since light applies pressure to surfaces, the stream of photons can be used for propulsion in a near-frictionless environment. This concept is the background for light (or solar) sails. It is a method of space travel that would negate the need for on-board fuel. Sails using the solar wind or only the light from stars are less efficient at larger distance from the Sun.

Solar Balloons Provide Electric Power


Instead of large expensive solar panels or costly concentrating mirrors, Cool Earth uses balloons made of metalized plastic films. Half of the balloon is transparent, letting the light in to be concentrated into a small, high-efficiency solar panel by the concave interior, providing from 500 watts to 1 kilowatt. They are supported by cables, leaving the ground below clear and limiting environmental impact. See Cool Earth website

Kurilpa Bridge Is Solar Powered


The Australian city of Brisbane opened the world's first large-scale solar-powered bridge. The 470m Kurilpa Bridge accommodates pedestrians and bicycles, and sports 84 solar panels that power an array of light-emitting diodes (LEDs). The panels supply between 75 and 100 per cent of the bridge's lighting needs. Read more on Solaripedia

International Space Station All Solar Powered


The most powerful solar arrays ever to orbit Earth capture the sun's energy and begin the process of converting it into power for the International Space Station (ISS). Eight solar panels supply more than 100 kilowatts of electric power to the station. The panels are mounted on a metal framework 360 feet (109 meters) long. The International Space Station is a large, inhabited Earth satellite that more than 15 nations are building in space. The first part of the station was launched in 1998 and it orbits Earth at an altitude of about 250 miles (400 kilometers). Visit the NASA International Space Station website.

Zero Energy Home near Seattle Opens to Public


The Zero Energy Idea House at Bass Cove, near Seattle in Washington State, will provide approximately 5 kW of electricity to the home from its rooftop photovoltaics and a vertical axis wind generator. The home’s domestic hot water is also heated by the sun. The floors, walls, and roof of the Zero Energy Idea House are built with structural insulated panels, or SIPs, that are constructed with expanded polystyrene (EPS) foam sandwiched between sheets of OSB (oriented strand board), which is an engineered wood product made from small pieces of scrap wood. Read more at the project website The home is open the weekend of 7 & 8 November 2009. Image by Northwest Property Imaging.

Swiss Alpine Hut Powered by the Sun


The Monte Rosa Hut above Zermatt, Switzerland, is nicknamed "Mountain Crystal". The innovative building generates over 90 percent of its own energy and will serve the Swiss Federal Technical University in Zurich as an on-going research project in power and building service engineering. 2,883 meters above sea level, the New Monte Rosa Hut is currently the most complex wooden construction in Switzerland. Covered in a shimmering silver aluminum shell and with a photovoltaic system integrated in the southern facade, it generates its own power and is expected to be at least 90 percent energy self-sufficient. Solar collectors installed in the grounds generate solar heat, which provides warm water and heats the ventilation system's supply air to control the temperature in the rooms. In the few months of the year where the ice melts, the water is collected and stored in a cavern to provide the guests with flush toilets and four hot showers. A bacteria-based microfiltration system cleans the sewage; the graywater is then reused to flush the toilet and for washing. See more images at SOLARIPEDIA.com

REI Round Rock Store Employs the Sun


The REI Round Rock store has an exceptionally efficient heating, ventilation and air conditioning system and building envelope, more than 80 percent reduction of construction waste, green building education program and rooftop solar panel installation. Mounting on the green building success of its previous stores, including one in Boulder, Colorado, this second generation of green prototype store in Round Rock, Texas, is projected to consume 48% less energy than a typical store and generate a portion of its power from a solar panel installation and building integrated photovoltaics.
