Chemical engineering Professor Brian Korgel tests one of his printed solar cells

Cheaper solar cells – roughly one-tenth the cost of current day prices – could be available within three to five years thanks to a manufacturing procedure that uses nanoparticle ‘inks’ to print them like newspaper or to spray-paint them onto the sides of buildings or rooftops. Even windows could become solar cells thanks to the semi-transparent inks. 'Painting' solar cells on buildings has been an idea in the making for some time – Gizmag investigated the possibilities of 'solar paint' in 2008.  Read More

By day the sunflowers collect the sun's energy to provide power for the LEDs after dark

A boring and unattractive loading area at the rear of a retail development in Austin, Texas is now hidden from view by a collection of 15 huge blue sunflowers, the petals of which collect energy from the sun to power the artwork's LED lighting and generate funds to help towards costs. Whether driving past or walking through the Electric Garden, onlookers will be treated to an awe-inspiring panorama where art meets functionality.  Read More

Thanks to a system created by SRS Energy and offered exclusively as an upgrade option to customers of US Tile (the largest manufacturer of clay tile in the United States), those wishing to benefit from rooftop solar energy will no longer have to worry about any panels being stuck on the side of the roof and spoiling the aesthetics. The Solé Power Tile system is the first building-integrated photovoltaic roofing product designed to blend in with curved roof tiles commonly found in the Pacific West and Southwest of the United States.  Read More

The Sun Drive is superbly portable and can be charged with solar power or via USB

If you’re lucky enough to live somewhere that gets a decent amount of sun every year, investing in a solar charger to give portable devices a boost when out and about would be a wise idea and Korean company Zyrus has come up with something tidy and practical enough to hold genuine appeal.  Read More

KAIST Online Electric Vehicle uses non-contact magnetic charging to draw its power needs f...

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed an electric transport system where the vehicles get their power needs from cables underneath the surface of the road via non-contact magnetic charging. As well as potentially saving Koreans a lot of money by reducing crude oil imports, widespread adoption of the technology also offers the potential of improving air quality in currently polluted cities.  Read More

Penn State researchers, Bruce Logan, and Maha Mehanna, with the three-chambered microbial ...

Desalination plants generally employ one of two methods to produce clean water – reverse osmosis or electrodialysis. Unfortunately, both processes require large amounts of energy, but an international team of researchers has proven a process that cleans wastewater can also remove 90 percent of salt from brackish water or seawater while generating electricity.  Read More

The new prototype ThermaVolt II - improved technology delivering more energy at a reduced ...

Renewable energy technology company Entech Solar has completed a preliminary design review and prototype of its next-generation concentrating solar product, ThermaVolt II, which combines concentrating photovoltaic and thermal (CPVT) technology. The company says its product delivers four to five times the amount of energy compared to traditional photovoltaic systems and costs less to produce.  Read More

The Milan trade fair will commission the world’s biggest rooftop voltaic power installatio...

Bigger may not always be better but when it comes to solar power generation it's a plus. The rooftop photovoltaic power installation at the Milan trade fair will cover around 270,000 square meters (2.9 million square feet) and have a peak installed capacity of at least 18 megawatts (MW). This will put it ahead of the biggest existing rooftop solar plant at General Motors in Zaragoza in Spain, which has a peak capacity of 12MW.  Read More

The Solio H1000 hybrid is perhaps the most versatile solar charger on the market

Learning more about consumption levels and investing in a standby-saver or two to cut down on waste energy is a great way to start becoming more green in the home, but there are also ways to utilize renewable energy when you're out and about.  Read More

Prevent TV and computer equipment from wasting energy when on standby

Cutting down on unnecessary electricity usage has clear benefits for both the environment and your hip pocket, and devices that tackle the issue of standby power are an obvious place to start. Paul Lester takes a closer look at some of the current solutions on the market.  Read More
