By now, we should all know that how you drive has a huge influence on fuel economy, but knowing exactly how to drive in certain circumstances to maximize fuel economy isn't always easy. We've looked at various technologies designed to make the task of traveling at the most fuel efficient speed, taking the most fuel-efficient - if not necessarily the shortest - route, and taking into consideration traffic conditions, that little bit easier. Now there's an app for mobile devices that does all these things. Called EcoSpeed, its creators say it could provide fuel savings of as much as 30 percent. Read More

The Swiss design firm ROB GmbH (Robust Outdoor Brands), which created the portable kitchen unit Cuebe, has come up with a simple low-impact housing solution. Named the PODhouse, these prefabricated modules create a great sustainable micro home for the garden, a backyard office or even a secret holiday hideaway. The prototypes have been in development since 2003 and have since been optimized, tested and improved to create this final product now available for purchase. Read More

The CHIP House - which stands for "Compact Hyper-Insulated Prototype" - was started with the goal of creating a net-zero energy home (i.e. one that requires no external energy source), and it looks like the designers exceeded that target. The house actually generates three times as much energy as it uses thanks to solar panels and a host of energy saving measures. The incredibly energy efficient design would make the house stand out on its own, but the integrated Kinect controls and smart features push the CHIP House above your typical green-conscious home and into "home of the future" material.

In the face of potentially catastrophic effects on global food production, some have proposed drastic solutions to counteract climate change such as reflecting sunlight away from the Earth. A new study from the Carnegie Institution for Science examining the effects of sunshade geoengineering has concluded that such an approach would be more likely to improve food security than threaten it.

HyperSolar claims it is developing a zero carbon method of producing hydrogen gas from wastewater by harnessing solar energy. Hydrogen gas is a clean source of fuel in that, theoretically at least, the only waste product is water. But hydrogen gas does not occur naturally on Earth, and requires energy to create. Typically that energy comes from traditional, carbon dioxide-emitting sources, rendering hydrogen fuel rather less environmentally friendly than it has the potential to be. HyperSolar's work may mean truly clean, renewable hydrogen fuel could be a commercial reality sooner than we might have imagined. Read More

When oil gets spilled in a waterway, clean-up crews will often introduce a solution known as a surfactant. This is a detergent that lessens the surface tension between the water and the overlaying oil slick, causing the oil to form into individual droplets which then sink or get dispersed by wave action. Unfortunately, such detergents aren’t entirely environmentally-friendly themselves, so the use of them on oil spills has been criticized as simply replacing one pollutant with another. Now, however, scientists from the University of Bristol have created a magnetic soap, that could be removed from the water once it had done its job. Read More

Italy and France have joined forces to create the "Astonyshine" 100 percent solar home concept as part of the 2012 Solar Decathlon Europe. The international competition is open to universities from around the globe and promotes research into the development of efficient housing. Astonyshine is a modern reinterpretation of the classic Mediterranean villa, and is the result of the combined efforts from Polytechnic of Bari (Italy), University of Ferrara (Italy), Ecole Nationale Superieure d'Architecture Paris-Malaquais (France) and Ecole des Ponts ParisTech (France).

While the McGee house may look like any other new designer home in the neighborhood, its walls tell a different story. Designed by husband and wife team Karl Wanaselja and Cate Leger of Leger Wanaselja Architecture, the upper outside walls of the house are made from over 100 salvaged car roofs. In a pursuit to build a house that utilized green technologies and reused materials, the couple sourced car roofs from a selection of gray-colored cars that had been left for parts in local junk yards in Berkeley, California. Their biggest challenge was sourcing car scraps that were in relatively good condition, without dents and with a good paint finish. The scraps were then cut into long tile-like shapes and used to complete the upper outside walls of the house, rendering a similar appearance to slate. Read More

One of the biggest criticisms leveled at biofuels that are derived from crops such as wheat, corn and sugar cane, is that they result in valuable land being taken away from food production. For this reason there are various research efforts underway to turn seaweed into a viable renewable source of biomass. Now a team from Bio Architecture Lab (BAL) claims to have developed a breakthrough technology that makes seaweed a cost-effective source of biomass by engineering a microbe that can extract all the major sugars in seaweed and convert them into renewable fuels and chemicals.
