Tree seeds could provide low-cost water purification for developing nations

“In the developing world, more than 1 billion people cannot get clean drinking water... The United Nations says that dirty water causes 80 percent of diseases in the developing world, and kills 10 million people annually.” Those sobering lines are from the United Nations’ website, and underscore just how urgently needed water purification is in much of the world. What many people don’t realize, however, is that there are already naturally-occurring water filtration supplies available in many of these areas. They come in the form of seeds from the Moringa oleifera tree, and used properly, they can produce a 90.00 to 99.99% bacterial reduction in previously untreated water. Read More

Joos Orange personal solar charger: affordable, rugged and extremely energy-efficient

The Joos Orange personal solar device is an affordable, durable, and waterproof energy source that can be charged by a USB, works in low-light conditions and offers up to 20 times more energy when compared to existing personal solar devices. It delivers more than two and a half hours of cell phone talk time for every hour it has been charged and its polycarbonate case has been encapsulated in urethane ensuring that it is rugged enough to be used outside for many years. The battery can generate enough power to fully charge six standard cell phones or four smart phones and the unit is expected to retail for less than US$100. Read More

Waste-to-Biofuels plant to make gas from garbage

If you’re a fan of the original Back to the Future movie, then you probably liked the scene at the end where Doc Brown used some random household waste to fuel his time-traveling deLorean. Well, we’re now getting a little bit closer to that being a reality... sort of. While practical flying cars, time travel and cold fusion are still a ways off, the ability to power your car with garbage isn’t. Canadian biofuels firm Enerkem is currently working with the city of Edmonton, Alberta, to convert that city’s municipal waste into ethanol. This will lower the city’s greenhouse gas output, keep much of its waste out of the landfill, and produce a “clean” fuel Doc Brown would be proud of. Read More

Information is power for cheaper electricity

Most of the time people don’t really take notice of how much power they’re using because the information isn’t readily available or easy to understand, which is where smart meters come in. They provide users with up-to-date information about how much power is being consumed and how much it is costing, thereby providing the information needed to cut energy usage and save money. Software currently being developed will make smart meters even smarter and help consumers make even bigger savings. Read More

Rubber trailing edge flaps could result in quieter, more productive wind farms

If you’ve ever seen a commercial-scale wind turbine in real life, then you’ll know that they’re huge – a single blade can be as long as 60 meters (197 feet). Researchers from Denmark’s Risoe DTU National Laboratory for Sustainable Energy tell us that such blades can flex by up to six meters (20 feet) when subjected to strong wind gusts. Worse yet, the gust load is often not evenly distributed along the length of the blade, so it doesn’t flex evenly. Fortunately, the researchers are working on addressing this problem, by attaching flexible flaps to the trailing edges of the blades. These flaps come in the form of silicone rubber strips, which run the length of the blade. The result, we’re told, will be quieter, higher-output turbines. Read More

UN urges action on e-waste

Ever wonder what happens to discarded televisions and obsolete home computers, or do you prefer not to think about it? According to a United Nations study on recycling, the volume of disused electronic products, or “e-waste” as it is known, has risen dramatically as it coincides with growth in sales in developing countries.

EVOLUTE - the near-waterless toilet

Toilets use a lot of water. And once they’re done with that water, well, it’s very... used. So, any time anyone can suggest a way of limiting water usage in toilets, Mother Nature wants to hear about it. Recently, Australian inventors Tom Trainor and Mark Hutton came up with a product that they claim uses up to 90% less water than a regular toilet. The EVOLUTE’s patented new technology offers a greener, drier alternative to our current “swimming pool for your poop” model. Read More

Secret Energy Turbine: rooftop wind power in stealth mode

Few people would argue that having a rooftop wind turbine could help offset your power bills. Your neighbors, however, might not appreciate the sight of a windmill on your roof, nor would they like the sound of its blades whistling through the air. Don’t give up on the idea yet, though, because British inventor Rupert Sweet-Escott has come up with a product that he claims addresses those problems. His Secret Energy Turbine (SET) looks like an ordinary chimney stack and is boasts almost completely silent operation. Read More
