First commercial cellulosic ethanol plant in the U.S.
Image Gallery (2 images)
November 9, 2007 The production of ethanol as a cleaner alternative to fossil fuel throws up a number of challenges - in particular it has been argued that the amount of land required to produce crops for ethanol fuel production is too great, taking away land that is needed for food production. The use of cellulosic biomass to make commercial ethanol has been seen as a possible solution to this problem and now Range Fuels has now announced plans for the first commercial ethanol plant in the U.S. to use cellulosic biomass.

Waterproof, recyclable concrete – just add Hycrete
Image Gallery (2 images)
November 1, 2007 Hycrete Technologies has developed a water based admixture that acts as waterproofing and corrosion protection when added to regular concrete. It does this by sealing the capillaries within the concrete and making the resultant product completely waterproof. The Hycrete is so effective that no external waterproof membranes, coatings or sheeting treatments are required, which is good news for the environment as it is usually these waterproofing methods that render concrete unsuitable for recycling – without them the concrete can be crushed, recycled, and reused.

Image Gallery (10 images)
October 15, 2007 On any given day, over one billion people lack access to clean drinking water and over 50% of hospital beds are occupied by people suffering from water-borne diseases. In the face of these facts it is clear that any technological innovation that can help combat this problem is a worthy one, with water filtration systems such as the LifeStraw and the LIFESAVER bottle having recently grabbed our attention. Now new technology developed by Hydration Technologies (HTI) has become available that allows the user to create a safe, clean diluted sports drink from any contaminated (even sewage-like) groundwater source without the use of power, pumping or chemicals.

Masdar Initiative: the world's first zero carbon, zero waste city
Image Gallery (5 images)
October 12, 2007 The sleek, modern capital of the United Arab Emirates, Abu Dhabi, will be host to what is planned as the world’s first zero carbon, zero waste city. The project involves a six million square meter sustainable development that will combine traditional planning principals of a walled city with existing technologies. The planned development is a dense, car-free city to be constructed in an energy efficient two-stage phase. A large photovoltaic solar power plant will be constructed to power the city and the location is close to transport infrastructure with links to surrounding communities, as well as the center of Abu Dhabi and the international airport, by a network of existing road and new rail and public transport routes.
Flexible modules could transform windows and buildings into solar panels

October 11, 2007 Traditionally, solar panels for buildings have predominantly been stand alone systems mounted to roofs in order to capture sunlight. The growing focus on "green" energy and a move away from reliance on fossil fuels is driving smarter and more integrated methods of procuring alternative energy sources such as solar, and in line with this, the National Institute of Standards and Technology (NIST) has invested $4.7 million to develop technology that would allow windows and other building applications to be converted into solar panels.

New test facility to reduce the cost of solar energy
Image Gallery (2 images)
July 11, 2007 A new test facility that aims to cut the cost of large-scale solar thermal energy production has been inaugurated at Almería in southern Spain. Research scientists from Europe’s largest solar energy research institute, the Fraunhofer Institute for Solar Energy Systems, helped to develop the facility which uses a linear Fresnel reflector one hundred meters long to focus sunlight onto a steel absorber tube in which water is heated up to 450 degrees Celsius and used to drive electricity producing turbines. Finding more efficient ways to harness the sun’s rays is a key part of the shift towards renewable energy and solar thermal power, as one of the most efficient methods currently under development, is predicted to provide about 10% of the world's electricity by 2050.

Tidal energy generator to be built in Northern Ireland
Image Gallery (3 images)
June 28, 2007 The tidal motion of water offers us an amazing source of energy - it's immensely powerful, predictable, reliable and can be harvested with no emissions and very little impact on the environment. Following successful testing off the coast of Devon, Marine Currrent Turbines is set to begin construction of the world's largest ever tidal turbine system off the coast of Northern Ireland - kind of like a wind farm that sits underwater. The 1.2MW generator will push enough power back into the commercial grid to supply 1000 homes, and will serve as a prototype commercial test of this clean, sustainable energy source. Read More
