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

The University of NSW have produced a PV system that converts over 40 percent of sunlight ...

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

Dr Shahriar Hossain is developing a wind turbine that uses a magnesium diboride supercondu...

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

The ecoDemonstrator 787 lifts off yesterday at Boeing Field in Seattle (Photo: Boeing)

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

The Eco-Safe Digester is a self-contained stainless steel unit that breaks down food waste...

The world produces a hell of a lot of waste and a great part of it is food waste. According to the United Nations Environment Program, around one third of the food produced in the world for human consumption every year is either lost or wasted. In an effort to deal with all this waste in a green way, New York-based BioHitech has developed a device that breaks food waste down into grey water and connects to a cloud system to allow the company to tap the power of big data to monitor and improve the performance of the units.  Read More

Researchers at ANU have replicated the primary capture of energy from sunlight (Photo: Shu...

Researchers at the Australian National University are one step closer to creating an artificial photosynthesis system after replicating one of its crucial steps. The development may lead to an abundant source of hydrogen, a cheap and clean fuel that could replace all petroleum products.  Read More

Just what the world needs: self-illuminating deodorant

A new Kickstarter campaign aims to make the deodorant stick more environmentally friendly by cutting back on plastic packaging. By replacing the disposable stick with a reusable dispenser, ClickStick's designers claim plastic waste is cut by as much as 90 percent. That's a sound idea, but one that risks undoing its good work by overcomplicating a simple product.  Read More
