The Ethiopian government has rolled out a new phone service that farmers can call to get information on crops in their native languages. The 8028 service also “pushes” targeted information to people in certain areas. A press release from the government says that three million people have used the pilot project service since its inception in July.  Read More

Milkweed seeds and fibers ready for propagating (Photo: Pollinator, CC BY-SA 3.0)

The humble milkweed may be a weed to most, but a company out of Granby, Quebec, is milking the plant for all it’s worth by developing a product for cleaning up oil slicks on land and water from milkweed fibers. Due to the fibers’ hollow shape – a unique feature in nature – and its naturally hydrophobic tendency, they repel water while absorbing more than four times more oil than the same amount of polypropylene materials currently used for spills.  Read More

Researchers have achieved a solar energy to hydrogen conversion efficiency of 12.3% using ...

Using solar energy to split water into its component parts, thereby allowing the solar energy to be stored as hydrogen fuel, generally involves one of two methods: using photoelectrochemical cells to directly split the water, or using solar cells to produce electricity to power an electrolyzer that separates the water molecules. One problem associated with the latter method is that it currently relies on rare metals. But now scientists from Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland have managed to do so using common materials, and have achieved a record solar energy to hydrogen conversion efficiency in the process.  Read More

The SprayLD system developed by University of Toronto researchers can spray colloidal quan...

Spray-on cells hold considerable promise for reducing the manufacturing costs of solar power. Within this field, colloidal quantum dots (CQD) have also been the focus of a number if research efforts, as they have the potential to soak up a wider range of the solar spectrum. Scientists at the University of Toronto have been aboard the quantum dot train for some time now and their latest breakthrough involves a new method for spraying solar cells onto flexible surfaces, a development that could one day see them coat anything from bicycle helmets to outdoor furniture.  Read More

Solar researchers working at the University of New South Wales claim to have produced a system that converts over 40 percent of incoming sunlight into electricity, thereby taking the title of highest solar efficiency for a photovoltaic system ever reported.  Read More

Conventional offshore wind turbines are expensive and complicated pieces of machinery – in a large part because of their complex and maintenance-intensive gearboxes. Dr Shahriar Hossain from the University of Wollongong in Australia is looking to slash production costs and drastically improve efficiency replacing these gearboxes with a superconducting coil.  Read More

One of the existing Tulip pilot plants

For five years now, a Tulip concentrating solar power plant has been operating at a kibbutz in Israel. In January 2012, a second one sprouted in Spain. While both plants have been successfully pumping out electricity ever since, they were also both built as research and development exercises. Soon, however, the world's first commercial Tulip plant will be built for a paying client, in Ethiopia.  Read More

Almost a year ago, Boeing announced that it was looking into running airliners on a mixture of jet fuel and "green diesel" – the latter of which is made from vegetable oils, waste cooking oil and waste animal fats. Yesterday in Seattle the corporation followed through on that plan, flying its ecoDemonstrator 787 flight test airplane on the fuel blend.  Read More

New research suggests that it takes just 10 years for CO2 emissions to have maximum effect...

Any given CO2 emission will have its maximum warming effect just 10 years later, new research from the Carnegie Institution for Science shows. The Institute of Physics (IOP) says this research, published in full on the web today, has "dispelled a common misconception" that the warming effects of CO2 emissions aren't felt for decades.  Read More

The Wind Tree turbine is designed to generate power from low-speed winds

Generally speaking, the peculiar appearance of wind turbines coupled with the fact they perform better when up high and out in the open sees them banished to uninhabited countryside, or even out to sea. But a French entrepreneur believes that sculpting them in the form of an artificial tree could lead to wider adoption in urban centers, making use of low winds that circulate around buildings and streets.  Read More
