Practical Action - technology challenging poverty Latin America In Peru and Bolivia, we help communities set up small-scale technological solutions in remote areas where there is no access to basic services, including electricity, heating, clean water and sanitation. Western Africa Building on our recent extension of consultancy work into west Africa, Practical Action has recently set up an office to deliver impact at scale in Francophone west Africa.

FAQs: The Safety of Plastic Beverage Bottles » en español To help assure the safety of our food, the U.S. Food and Drug Administration carefully reviews food and beverage packaging materials, including plastics for beverage bottles, before allowing them on the market. Most convenience-size beverage bottles sold in the United States are made from polyethylene terephthalate (PET). PET has become the material of choice for bottled beverages because it is lightweight and shatter resistant, and PET has been extensively tested for safety. Bottles made with PET are widely used for everything from water and fruit juice to soft drinks and even beer.
Technology - Luminaid: Shining a light on disasters Haiti’s devastating earthquake in 2010 shattered the country’s infrastructure, but for one designer it proved to be an illuminating moment. Before you read this, close the door, draw the curtains, and turn out the lights. If you are reading on your laptop, momentarily close the lid. Now that you are back, think about how it felt.
Plants For A Future : 7000 Edible, Medicinal & Useful Plants Recommended this month New Book ** Edible Perennials: 50 Top perennials from Plants For A Future [Paperback] Current interest in forest or woodland garden designs reflects an awareness that permanent mixed plantings are inherently more sustainable than annual monocultures. They safeguard and enrich soil ecosystems, enable plants to form cooperative combinations, make use of layers above and below the soil, and they create benign microclimates which soften winds and recycle the rain. Pinterest and Feminism On constructing a lesson plan to teach Pinterest and feminism I teach sociology; usually theoretical and centered on identity. I pepper in examples from social media to illustrate these issues because it is what I know and tends to stimulate class discussion. It struck me while reading arguments about Pinterest that we can use this “new thing” social media site to demonstrate some of the debates about women, technology and feminist theory. We can view Pinterest from “dominance feminist” and “difference feminist” perspectives to both highlight this major division within feminist theory as well as frame the debate about Pinterest itself. Secondly, the story being told about Pinterest in general demonstrates the “othering” of women.
Home uses for Hydrogen Peroxide for disinfection and sanitizing Many home uses for hydrogen peroxide are all about disinfection and sanitizing. Or, to say it another way: OUT WITH THE GROSS! Many of the benefits of hydrogen peroxide begin with its value in killing germs. I've been using hydrogen peroxide for years, and some of my favorite uses are for disinfection. Tracking Frackers From the Sky Ever since the natural gas boom took off in Pennsylvania in 2006, some people living near the drilling rigs have complained of headaches, gastrointestinal ailments, skin problems and asthma. They suspect that exposure to the chemicals used in the drilling practice called hydraulic fracturing, or fracking, triggers the symptoms. But there’s a hitch: the exact locations of many active fracking sites remain a closely guarded secret. Brian Schwartz, an environmental epidemiologist at Johns Hopkins Bloomberg School of Public Health and his colleagues have teamed up with Geisinger Health System, a health services organization in Pennsylvania, to analyze the digital medical records of more than 400,000 patients in the state in order to assess the impacts of fracking on neonatal and respiratory health. While the scientists will track where these people live, says Schwartz, state regulators cannot tell them where the active well pads and waste pits are located. “It’s a big planet,” says Amos.
Dutch kids have a different relationship to the bicycle Writing about Groningen (twice) has been fun, and reminiscing has brought up a couple of other article ideas. Lloyd and Mike enthusiastically encouraged me to go further down this route, so here's a piece on my observations regarding the quite different relationship Dutch kids have to bicycling (compared implicitly to American kids since I'm American). Walking through the socialization process, let's start with babyhood. Kirsch Kirschwasser, produced in Germany and bottled at 40% ABV. A kirschwasser (/ˈkɪərʃvɑːsər/ KEERSH-vahs-ər; German: [ˈkɪɐ̯ʃvasɐ], German for “cherry water”) or kirsch is a clear, colorless fruit brandy traditionally made from double distillation of morello cherries, a dark-colored cultivar of the sour cherry. However, it is now also made from other kinds of cherries. The cherries are fermented complete (that is, including their stones). Unlike cherry liqueurs and so-called “cherry brandies”, kirschwasser is not sweet.
Eco Toilets - Earthrise Gelareh Darabi is attending a lively party at a temporary camp in Haiti's Cite Soleil. The reason for the celebration – the unveiling of a new, environmentally-friendly toilet, which will also be used to create much-needed compost for the adjacent community garden. In many of Haiti's camps, hundreds of residents are obliged to share a single toilet, so it is no wonder that this new innovation is welcomed. The slums and camps of Haiti, as is the case in most developing countries, have woefully inadequate sewage systems which means that human waste spills onto the streets and into the water system. As well as being a sanitation problem, it is also a huge environmental problem. If not properly treated, human sewage can play havoc with ecosystems, destroying lakes and rivers by depleting oxygen.
New technique removes even trace amounts of heavy metals from water A new process has been developed for removing trace amounts of heavy metals from water (Photo: Luis nunes alberto) Image Gallery (2 images) Once released into the environment from industrial sources, trace amounts of heavy metals can remain present in waterways for decades or even centuries, in concentrations that are still high enough to pose a health risk. While processes do exist for removing larger amounts of heavy metals from water, these do not work on smaller quantities. Now, however, scientists from Rhode Island's Brown University have combined two existing methods, to create a new one that removes even trace amounts of heavy metal from water. Known as the cyclic electrowinning/precipitation (CEP) system, the process involves increasing the concentration of heavy metals in water samples, until it's high enough to be effectively removed.
Why the Dutch don't wear helmets One of the perennial topics of controversy in the bicycling community is helmets, and the controversial issue is not about which color is prettiest. I won't spend too much time on the backstory, but the controversy is whether or not helmets should be a must (for their skull & brain protection benefits) or left at the shop (because they inhibit bicycling, which results in less bicycling, which makes bicycling less safe). "Must" could mean a legal requirement, or it could simply mean a personally imposed must – it depends on the conversation. I used to be the director of a nonprofit that was primarily focused on promoting and supporting bicycling in the greater Charlottesville area.
