Wall guards and corner guards don’t make for particularly compelling architecture by themselves. Most people don’t pay attention to them. They are an element in hospitals and offices, particularly where there is high traffic, to protect the walls from damage. And they are often made of PVC plastics. Rather than being manufactured with PVC plastic, [...]
It’s pretty convenient that many of the world’s major cities happen to be fairly near to renewable energy sources. Two of America’s largest cities, New York and San Francisco, happen to have extremely strong tidal currents. And while we’ve previously reported that New York is working on some tidal infrastructure, today we’re excited to announce [...]
It’s wonderful to see that environmental issues are reaching the emo sect as well. It is worth mentioning that, obviously, emo kids do use less electricity than normal kids. For one thing, they don’t need to actually go anywhere in order to listen to music and be sad, so you don’t need a car at [...]

Could photovoltaics hit 50% efficiency? Spectrolab in Sylmar, CA is gunning for it with a record high 40.7% conversion rate from their latest solar cell. Spectrolab’s solar panels are similar to those from Soliant Energy, concentrating light onto solar cells using mirrors and lenses. However, Spectrolab goes beyond the typical silicon based solar cell: theirs [...]
Really, why should I spend tons of money on a laptop bag that has likely been shipped from china, when I could create a low-impact, high-strength, water-proof laptop bag out of shipping materials already arriving on my front doorstep? Instructables has an awesome tutorial on how to turn three laptop bags a little bit of [...]
Ben Storan just won first prize in BSI’s 2007 Sustainability awards for his design for a shape-shifting, vertical axis personal wind turbine. The device works very much like the Quiet Revolution wind turbines. The design is less efficient than Quiet Revolution turbines, but much more efficient than other turbines marketed toward homeowners. Plus, this new [...]
Thirty percent corporate computers are not swtiched off at night. Or so says a study from 1E, a power management software company. And the cost of that over-night computing? 14.4 million metric tons of CO2 and $1.72 Billion. Now, we should keep in mind that this study was done by a company trying to sell [...]

Dear EcoGeekI did a survey and I have 33 recessed bulbs in the house (120W)! I’ve switched all my non-recessed bulbs with CFLs, but I need something for our recessed lighting. So my question is why aren’t these ultra-efficient LED lights being produced in greater quantities (and this bringing the costs down)? - David David,Thirty [...]
Ah ah aaah ah ah aahhh…*ahem*…sorry…this kind of stuff gets me excited. Ceravision has just announced that they have developed a lightbulb that is 50% efficient (more than twice the efficiency of CFLs) and will last…um…forever? No, that can’t be right, but a very very long time anyhow. They say they expect their new lamp [...]
