Coated polymer stack promises to keep your roof cool in summer

Of all the scenarios you'd want to find yourself in a heatwave, being barefoot on a hot tin roof would be toward the bottom of the list. These exposed surfaces soak up sunlight to slowly but surely transform into corrugated hotplates, compounding the sweltering ambient temperatures and warming the living space below. But a team of Sydney-based scientists has developed a new material that's claimed capable of keeping a rooftop cooler than the air that surrounds it, saving energy and sweating residents in the process.Read More

Ocean Cleanup concept to become a reality next year

A concept designed to rid the oceans of plastic waste is to become a reality next year. Boyan's Slat's Ocean Cleanup system is expected to be deployed in the second quarter of 2016 in the waters between Japan and South Korea. It will be the longest floating structure ever deployed in the ocean.Read More

New model predicts significant Everest ice loss

A team of researchers from France, Nepal and the Netherlands has worked to produce a new model to predict the future changes in glaciers in the Everest region of the Himalayas. While the study, which was conducted by the European Geosciences Union (EGU), only represents an initial approximation of ice loss in the region, the model suggests that dramatic changes may be ahead.Read More

CryoSat detects heavy Antarctic ice loss

The ESA CryoSat mission has detected significant ice loss in a usually stable Antarctic region. The data recorded by the satellite revealed how multiple glaciers along the Southern Antarctic Peninsula started shedding ice in the 2009, with no prior warning.Read More

Vortex bladeless turbines wobble to generate energy

Looking somewhat like a giant reed gently swaying in the wind, the new Vortex bladeless wind-driven generator prototype produces electricity with very few moving parts, on a very small footprint, and in almost complete silence. Designed to reduce the visual and aural impact of traditional spinning-blade turbines, this new device takes advantage of the power contained in swirling vortices of air.Read More

Tesla unveils battery storage system for home, business and utility use

The Tesla home battery system hinted at by CEO Elon Musk several months ago has finally been unveiled by Musk himself at the company’s design studio in Hawthorne, California. Dubbed the Powerwall, the stationary home battery offers 10 kWh of storage capacity for the relatively modest price of US$3,500. A smaller unit is also available at 7 kWh for $3,000, and homeowners can stack multiple units if needed. Read More
