New "smart window" material selectively blocks light and/or heat

By - July 24, 2015 2 Pictures

In an effort to improve the energy efficiency of building, researchers have sought to develop windows that change transparency to let more light – and therefore heat – through when it's cold, and less when it's hot. Unfortunately, these methods tend to impede the passage of visible light, some by tinting panes and others by complete obscuration. But a team at the Cockrell School of Engineering at The University of Texas at Austin has developed a "smart window" technology that allows the passage of visible light while blocking heat, or vice versa.

New heat-recovery system makes Stanford one of world’s most energy-efficient uni's

By - April 26, 2015 7 Pictures
At Stanford University in California, it’s normally the Nobel-winning researchers who make the news. But with the commissioning of a novel renewable energy system, the campus’s humble heating and cooling system has grabbed some headlines. Using a first-of-its-kind heat recovery system, and drawing a substantial percentage of its electricity from solar, the university is greening up its operations in a move that will see greenhouse gas emissions cut by 68 percent and fossil fuel use cut by 65 percent.

Researchers theorize two mechanisms that prevent prolific star creation in galaxy clusters

By - March 11, 2015 1 Picture
For a long time, scientists have been searching for an answer as to how galaxy clusters regulate the number of stars they create. Given that the amount of interstellar gas used to create the stellar giants exists in such abundance, this theoretically allows for the creation of many times the current number of stars. A team of researchers from MIT, Columbia University and Michigan State University believe they have found the answer. Read More

Carbon nanotube-based anti-icing coating proves itself in wind tunnel testing

By - February 22, 2015 3 Pictures
There are numerous types of systems designed to prevent ice forming on aircraft surfaces during flight. Some reroute hot air produced by jet engines, others generate their own heat, others knock ice off through mechanical force, while others still release antifreeze chemicals onto the wing. Battelle has recently tested its carbon nanotube-base HeatCoat technology that it claims is lighter and less power hungry than such systems. It also has no moving parts and could easily be retrofitted to existing aircraft. Read More
