Inhabitat's Week in Green: the dangers of LED lighting, self-healing nanotech, and spray-on solar power
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. This week Inhabitat shed light on the next generation of solar power as we showcased a spray-on film capable of generating 300% more energy than traditional photovoltaics and a new breed of nanotech cells that can heal themselves like plants. New biofuel projects also broke ground around the world as the US began construction on its first commercial biofuel plant and Canada upgraded a waste plant to be powered by soda and beer. And another farticle, er, article covers a project in Greenpoint, Brooklyn that takes the result of the results of those drinks (methane) and turns it into fuel. We also interviewed energy efficiency expert David Johnston, who shared 5 tips that could cut your electricity bill by up to 50 percent. And on a more sour energy efficiency note, we were appalled to see this new study that found that LEDs, like CFLs, also contain unsafe levels of carcinogenic toxins. The big (or should we say B.I.G) architecture news of the week was the unveiling of Bjarke Ingels Group's sloping residential pyramid for midtown Manhattan. In transportation news, Nissan revealed plans to roll out its Tesla-trouncing ESFLOW electric supercar at the Geneva Auto Show, while Chevrolet announced that the Volt will receive a $5,000 tax rebate in California. We also applauded the US government's $53 billion plan to jump start high speed rail, while republicans rallied against the movement towards more efficient infrastructure. We also showcased several stylish examples of wearable eco tech - a set of bio sensors that improve physical and emotional health, and a pair of GPS-enabled snow goggles that are perfect for shredding through uncharted territory. Finally, we shared 10 green iPad cases that are perfect for protecting your e-reader from blustery winter weather.
New research says e-cigarettes are safer than real ones, no cigarettes safer still
Research swayed back and forth on the health risks associated with e-cigarettes since their debut in the US about three years ago. The faux cigs, which are essentially nicotine inhalers intended to help smokers kick the actual smoking habit while still getting their dose of nicotine, the main addictive ingredient in tobacco. In the first truly comprehensive study of the somewhat controversial nicotine replacement method, researchers at Boston University's School of Public Health has found that not only are e-cigarettes much safer to "smoke" than normal ones, they may also aid in kicking the addictive habit altogether. According to the researchers, "few, if any" of the chemicals found in e-cigarettes pose serious health risks, and carcinogen levels in them are up to 1,000 times lower than in actual tobacco. This research, of course, disagrees with the FDA's findings that essentially, the chemicals found in e-cigarettes were risky and unknowable. The FDA has yet to evaluate e-cigarettes the way that they have done with all medications and other nicotine replacement products, so we can't be sure, but it's looking more and more possible that if you just need to smoke, an e-cigarette may be a safer route... for everything but your dignity, of course.
E-cigarettes contain carcinogens and toxins after all, FDA warns
In case you ever of the mindset that e-cigarettes were somehow toxin free, at least compared to the more traditional smokes, along comes the FDA to shatter your illusions. A report this week from the government agency calls out the product with a safety warning, charging that the cartridges they examined contained "carcinogens and toxic chemicals such as diethylene glycol, an ingredient used in antifreeze." The FDA says it can't confirm the extent of the health issues, as it's only done limited testing and it hasn't been formally submitted for review, but it doesn't look quite as risk-free as previously touted. Don't say the WHO never warned ya. So remind us again, what's the point in smoking one of these over an old school cigarette?[Via Switched; thanks, flatlander85]
