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.
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.
Just weeks after producing its first batch of synthetic diesel fuel made from carbon dioxide and water, Audi has laid claim to
another synthetic, clean-burning and petroleum-free fuel called
"e-benzin." The fuel was created by Audi's project partner Global
Bioenergies, in France.
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.
Researchers at the University of Aalto, Finland have broken the efficiency record for black silicon solar cells – a type of cell that can gather sunlight even from tight angles – by almost four percent.
