Self-healing “artificial leaf” produces energy from dirty water

By - April 10, 2013
Back in 2011, scientists reported the creation of the “world’s first practical artificial leaf” that mimics the ability of real leaves to produce energy from sunlight and water. Touted as a potentially inexpensive source of electricity for those in developing countries and remote areas, the leaf’s creators have now given it a capability that would be especially beneficial in such environments – the ability to self heal and therefore produce energy from dirty water.

EWICON bladeless wind turbine generates electricity using charged water droplets

By - April 3, 2013 2 Pictures
Wind energy may be one of the more sustainable sources of power available, but the spinning blades of conventional wind turbines require regular maintenance and have attracted criticism from bird lovers. That might explain why we've seen wind turbine prototypes that enclose the blades in a chamber or replace them entirely with a disc-like system. But researchers in the Netherlands set out to eliminate the need for a mechanical component entirely and created the EWICON, a bladeless wind turbine with no moving parts that produces electricity using charged water droplets.

Crowdfunding success for 4th-grader solar-powered classroom bid

By - March 27, 2013 5 Pictures
After looking into the pros and cons of nine methods of electricity production (including coal, geothermal, biomass, and solar), a group of 9 and 10 year-olds from Central Park School for Children in Durham, North Carolina decided that their classroom should be powered using only energy from the sun. They hit Kickstarter at the beginning of this month with a modest funding goal of just US$800 to help finance the installation of a small PV panel array – a target that was smashed in less than a day.

Japanese bank to fund first U.S. offshore wind farm

By - March 21, 2013
Not having a section devoted to cures for insomnia, Gizmag tends to pass over press releases about investment agreements. Tuesday's announcement that the Bank of Tokyo-Mitsubishi UFJ (BTMU) is to find somewhere in the order of US$ 2 billion for the Cape Wind is extremely interesting, however, as it means the U.S. should finally build its first offshore wind farm, with construction slated to commence before the year's end.

World’s largest concentrated solar power plant opens in the UAE

By - March 18, 2013 6 Pictures
Thanks to its low latitude and low percentage of cloudy days, the United Arab Emirates (UAE) is an ideal location for capturing solar energy. So it’s no surprise to see the world’s largest operating concentrated solar power (CSP) has launched in the sun-soaked Middle Eastern country. Officially inaugurated this week by UAE President and Ruler of Abu Dhabi, Sheikh Khalifa bin Zayed Al Nahyan, Shams 1 is a 100 MW CSP that will power 20,000 UAE homes. Read More

Nanotubes boost potential of salinity power as a renewable energy source

By - March 12, 2013
In November 2009, Norwegian state owned electricity company Statkraft opened the world’s first osmotic power plant prototype, which generates electricity from the difference in the salt concentration between river water and sea water. While osmotic power is a clean, renewable energy source, its commercial use has been limited due to the low generating capacities offered by current technology – the Statkraft plant, for example, has a capacity of about 4 kW. Now researchers have discovered a new way to harness osmotic power that they claim would enable a 1 m2 (10.7 sq. ft.) membrane to have the same 4 kW capacity as the entire Statkraft plant. Read More

Analysts say renewable energy now cheaper option than new fossil fuels in Australia

By - February 14, 2013
In 2008, the Garnaut Climate Change Review ranked Australia as the highest per capita emitter of greenhouse gases of any OECD country and amongst the highest in the world. One of the reasons for the country's high carbon footprint is its reliance on coal for electricity generation – 54 percent of it, according to the Australian Coal Association. But a new study by Bloomberg New Energy Finance (BNEF) points to a cleaner energy future with the claim that unsubsidized renewable energy is now a cheaper option for electricity generation than new coal- or gas-fired power stations.

Cantilevered residential heliostat takes shape in Sydney

By - February 11, 2013 17 Pictures
A major urban redevelopment is taking place in Sydney, Australia, as it attempts to become one of the word’s most liveable green cities within a 20-year time-frame as part of the “Sustainable Sydney 2030” vision. One remarkable inner city project passed a major milestone this month as part of its contribution to the eco plan. The development, named “One Central Park,” had its 110-tonne steel heliostat frame hoisted into place during the early hours of February 1st. Read More

Blade Dynamics to make first 100-meter wind turbine blades?

By - January 11, 2013 3 Pictures
The Energy Technologies Institute in the United Kingdom has announced that UK-based wind turbine blade manufacturer Blade Dynamics has been awarded a contract that will see the creation of the world's longest turbine blades, between 80 and 100 meters (262 and 328 feet) in length. Currently, the longest turbine blades are for offshore wind farms, maxing out at 75 meters (246 feet). Read More
