Solar Nanocell Design Boosts Absorption & Cut Costs

Written by , on February 21, 2012

Researchers at  Stanford University have created photovoltaic nanoshell structures inside of which light resonates, allowing the solar cells to absorb more light. The inspiration for the cell structure came from whispering galleries – specially designed round rooms that allows a whisper from a person on one end to be carried around and heard clearly by […]  Read more »

Cheap Plastic Absorbs CO2 from the Air

Written by , on February 20, 2012

Scientists at the Loker Hydrocarbon Research Institute and the University of Southern California, Los Angeles have produced a cheap plastic capable of removing large amounts of carbon dioxide from the air. The material has the potential to be used in large-scale batteries as well as "artificial trees" to remove carbon dioxide from the air. The […]  Read more »

Common Plastics from Plants

Written by , on February 18, 2012

Dutch scientists from Utrecht University and the Dow Chemical Company have found a way of turning plant matter into the building blocks of common plastics using a catalyst made from iron nanoparticles, that offers an alternative to oil-based production. Existing bioplastics, which are made from crops such as corn and sugar, have only limited use […]  Read more »

More Efficient Thin-Film Solar Cells

Written by , on February 17, 2012

A team of researchers from Melbourne’s Swinburne University of Technology and Suntech have developed what they clain to be the world’s most efficient broadband nanoplasmonic thin-film solar cells. The researchers initially improved silicon based thin film cell efficiency by embedding gold and silver nanoparticles into the cells. This increases the wavelength range of the absorbed […]  Read more »

Liquid Air Used to Store the Wind’s Energy

Written by , on February 15, 2012

A British company,Highview Power Storage has developed what it claims is a way of storing surplus wind energy which can then be released during periods of calm. The energy storage system uses liquid air as the storage medium. Liquid air is hundreds of times more energy dense than water and can easily be stored in […]  Read more »

More Accurate Measures of Melting Icecaps

Written by , on February 15, 2012

U.S. scientists using satellite data have established a more accurate figure of the amount of annual sea level rise from melting glaciers and ice caps. There are more than 160,000 glaciers and ice caps worldwide but annual changes in mass have been directly measured for only 120 of them and, in most cases, only within […]  Read more »

Camp/Third-World Stove Also Provides Electricity

Written by , on February 9, 2012

Biolite has developed a portable camp stove that uses the heat from the fire to also generate electricity for charging batteries. The company has another model under development designed to provide electricity, as well as a clean-burning cooking stove, for developing countries.  Read more »

Solar Power from Grass Clippings

Written by , on February 4, 2012

In the video below, MIT researcher Andreas Mershin describes advances in producing photovoltaic cells based on waste plant material, such as grass clippings. The work is an extension of a project begun eight years ago by Shuguang Zhang, associate director at MIT’s Center for Biomedical Engineering. Zhang extracted the tiny structures within plant cells that […]  Read more »
