Previous studies have indicated that painting the roofs of buildings white could be a low tech way to reduce global warming by reflecting the sun’s rays back into space. Now the first computer modeling study to simulate the impacts of white roofs on urban areas worldwide has added more weight to such a proposal indicating that painting every roof in a city entirely white could cool the world’s cities by an average of about 0.7 degrees Fahrenheit or 0.4 degrees Celsius.

Have you ever wanted to create your own little planet? Do you like aquatic life, but think that aquariums are too much work? If your answer to either of those two questions is Yes, then you might quite enjoy owning a miniature closed aquatic ecosystem. All you need is a credit card, or a clear glass jar, some stuff from a pond, and an appreciation for things that exist on a small scale. The result will be a self-sustained miniature world that doesn’t need feeding, filtration, or anything other than light, from the outside world. Read More

In response to a Marine Corps requirement from Iraq for an expeditionary renewable power system, the Office of Naval Research (ONR) Advanced Power Generation Future Naval Capabilities program has introduced technology designed to harness some of the sunlight that beats down upon U.S. Marines operating in the Arabian Desert. Fueled by the sun, the Ground Renewable Expeditionary ENergy System (GREENS) is a portable, 300W, photovoltaic/battery system that provides continuous power to marines in the field. Read More
3-D photovoltaic systems go where the sun don’t shine

The photovoltaic (PV) panels adorning the rooftops of buildings around the world have become a visible sign of the shift towards environmentally friendly solar power. Now researchers have developed a new type of three-dimensional PV system using optical fiber that promises solar generators that are foldable, concealed and mobile, meaning they could be hidden from view and leave rooftops panel-free.

Attention all males! When you were young, did you ever dream about being given the keys to the toy shop? Well, for four very lucky men that dream was realized when they won a competition to help design the red-blooded man’s recreational vehicle (RV). They chose to incorporate a bar, disco, outdoor theater, rooftop sundeck, two plasma screens, sound system, poker table and barbecue – and no needless devices in the kitchen. Read More
