Don't worry, it's not as easy as it sounds; in addition to powdered donuts, you'll need some Passion tea from Starbucks and a bottle of Everclear. Even if the cells don't work you've got some good provisions to keep you busy till Monday. Enjoy.... Read the full story on TreeHugger

Outspoken Carbon Monitoring: Zerofootprint's RFID TalkingPlugs

Thu, 19 Nov 2009 14:16:10 GMT

The CEO of Zerofootprint, Ron Dembo, is a man who has often written and been written about on TreeHugger. Now it looks like this outspoken man is ready to let the world's power plugs start speaking for themselves. Zerofootprint, his energy and carbon management firm, has broken into the hardware world with TalkingPlugs, a system that includes devices that attach over existing electrical outlets, giving them special powers: namely the ability to wirelessly transmit their energy output and, inversely, to be remotely controlled and programmed. This opens to door to some very cool features.... Read the full story on TreeHugger

Stunning Reclaimed Furniture with Deep Southern Roots

Thu, 12 Nov 2009 13:32:50 GMT

Furniture made from reclaimed wood, whether it be from the wild or from a collapsing warehouse, expresses the human and natural history of the region it was plucked from. Last week I wrote about Urban Woods, an LA-based furniture shop whose materials reflect the unique environs of California. This week, Garden & Gun (one of my favorite southern magazines) turned me on to Turning House Furniture, a Virginia-based company building impeccable pieces with wood reclaimed from such quintessentially southern structures as an R.J Reynolds tobacco warehouse in North Carolina and the Rip Van Winkle bourbon factory in Kentucky....

Jerome Ringo, President of the Apollo Alliance

Thu, 12 Nov 2009 12:05:19 GMT

A healthy and high-tech green collar economy has been a great promise of the Obama administration. On the front lines of the fight to create green jobs and spur the economy is the Apollo Alliance, an amalgam of labor, business, and environmental groups. Jerome Ringo, President of Apollo, speaks with TreeHugger Radio about his group's "moonshot mission," the vitriol of Glenn Beck and Fox News, the resignation of Van Jones, and the role of African Americans in the climate fight. Ringo was a keynote speaker at this year's Bioneers conference, and we thank the conference organizers for helping arrange this interview.

Ford Adds Wheat Straw to the 2010 Flex

Wed, 11 Nov 2009 13:32:07 GMT

Even in the early heydays, Henry Ford was fond of using plants like hemp and straw to reinforce plastic components for his cars. Now bioplastics are back and turning up in cell phones, forks, and more. Ford Motors started trying out soy-based seat foam a few years back, and is now expanding its palette of plant plastics. It's a small step, but the 2010 Ford Flex will be the first car to feature a plastic part that contains wheat straw.... Read the full story on TreeHugger

Harnessing Bacteria to Grow Custom Packaging

Mon, 09 Nov 2009 13:06:38 GMT

Some things have no business being packed up and shipped at all, like software serial numbers. But until we learn to teleport fragile objects, we're going to have to protect them for the journey. This ambitious concept called Bacs harnesses the bacterium acetobacter xylinum to self-assemble around an object, encasing it in a biodegradable paper-like shell. For this innovative notion, designer Mareike Frensemeier took third place in Cargo Packs 2020, a design challenge staged by Bayer MaterialScience. By slathering an object with the special culture and then offering it a sugary meal, the bacteria metabolize the glucose into a "fibrous nano-scaled cellulose network."...

People's Design Award Bestowed on the Trek Lime

Thu, 05 Nov 2009 15:03:41 GMT

When Trek unveiled the Lime back in 2007, the mission was to bring delightful, non-threatening biking to grown-ups. Some nice validation came last week when the Lime won the 2009 People's Design Award, a subcategory of the prominent National Design Awards. A simple city bike with an upright riding posture, the Lime uses Shimano's Coasting automatic three-speed transmission (a pretty complex system with a very simple user interface) and a back-pedal brake rather than hand levers. The mid-priced bike also packs a clever storage compartment into the bike's seat with enough room for keys, cell, and grocery money.... Read the full story on TreeHugger

Artful Reclaimed Furnishings from Urban Woods

Wed, 04 Nov 2009 13:31:46 GMT

Since the leveling of forests is linked to everything from sneakers to burgers to biofuels, it's refreshing to find a furniture shop souring all of its timber from reclaimed sources. Urban Woods hand makes all its pieces in Los Angeles from wood that was milled between 50 and 100 years ago. Aesthetically, these are down-to-earth collections, more refined and tame than Hugo Franca's gnarly masterpieces, or even Carlos Motta's rustic reclaimed recliners....

Biomimicry is everywhere these days. It seems increasingly clear that design inspired by nature will play a great big role in our energy future. Case in point: Green Wavelength, an up-and-coming California engineering biz, has prototyped a small wind turbine, the xBEE, the elegant flapping motion of which is inspired by the buzz of insect wings (see the video below). Borrowing design cues from nature is already changing the face of technology, especially in the swirly realm of fluid dynamics. We've seen fan blades inspired by the bumpy fins of whales, solar cells made more efficient by the texture of butterfly wings, turbine blades that mimic the hydrophobic surface of leaves, and maybe even high-MPG car coatings that are rough like shark skin....

When I was in college, a graffiti-writing friend took me to one of his favorite secret spots, a neglected section of elevated train track in Manhattan's meat packing district. We had to politely interrupt some transvestite prostitutes in an alley to climb the one scalable wall up to this derelict wonderland. Last month I found myself in that same spot, but it's now the High Line, an elevated New York City park, a mile-and-a-half long, that winds through Chelsea and Hell's Kitchen. Chicago is now looking at a similar project, but one more ambitious by several degrees of magnitude.... Read the full story on TreeHugger

Power Tripping Across America with Environmental Journalist Amanda Little

Thu, 29 Oct 2009 15:48:00 GMT

Amanda Little built a journalistic career decrying the pains and convulsions of our petrol-obsessed society, but it wasn't until she embarked on a very personal quest did the story of oil become illuminated in human terms. Amanda tells TreeHugger Radio how, to write her first book, Power Trip: From Oil Wells to Solar Cells--Our Ride to the Renewable Future, she went inside the Pentagon and the Talladega Superspeedway, visited corn farmers and rode along with T. Boone Pickens, witnessed a boob job and landed on a Gulf Coast oil rig. Through it all, she learned a new-found respect for the hydrocarbon, and a renewed vision for a green future.

Supermodels Get Nearly Naked for Climate Change (Video)

Wed, 28 Oct 2009 07:46:00 GMT

October 4th marked a day of action that spanned 181 countries and 5,200 separate events, all for the sake of one number: 350. Inspired by this colossal (and exceedingly creative) global display, a small cadre of New York models put their beautiful bodies behind the message of atmospheric salvation. In this video for 350.org, they count backward from 390 parts per million-our current carbon dioxide levels-shedding layers as they go. But they stop at 352, just shy of the mark, leaving the final glory to our imaginations. (Video after the jump) ... Read the full story on TreeHugger

Helix-Shaped Wind Turbines Could Power Nigerian Cell Towers

Tue, 27 Oct 2009 17:08:43 GMT

Vertical axis wind turbines are an intriguing technology that most people still know little about. The turbines we are accustomed to use blades to turn a horizontal axis (which is often housed in the little cupola on the top of the turbine's tall stem). Vertical axis turbines turn a vertical shaft (picture a barber's pole) to generate power. Helix Wind, a US maker of some very slick looking vertical axis wind turbines, has struck a deal with a West African telecom company to power cell phone towers with wind. This allows the towers to operate autonomously without transmission lines or diesel generators.... Read the full story on TreeHugger

Youngster Jesse Graves has been running around Milwaukee stenciling his artistic messages of eco-sanity on sidewalks, walls, and concrete pylons. But lucky for his lungs and his criminal record, he's doing it with mud instead of paint. Graves, who signs his work MSR (mud stencils rule), writes: "I use mud or earth because it is a fundamental life-giving substance, logical for my messages. Mud stencils are an evolving medium, intended for art and social justice, not corporate advertisement."... Read the full story on TreeHugger

Margaret Atwood is one of the most respected authors of our time, with dozens of books of poetry and fiction to her name, among them Cat's Eye, The Handmaid's Tale, and Oryx and Crake. Her latest book, The Year of the Flood, is set in a fallen future: society has crumbled, climate change and pandemics ravage the planet, and people are forced to rediscover their relationship with the land. Miss Atwood chats with TreeHugger about the God's Gardeners (the book's rooftop-gardening eco cult), her pantheon of ecological saints, and the greening of her book tour and her own life.

They call them Hangeliers. In East Vancouver, designers Alex Witko and Courtney Hunt spend their days between the hardware store, the studio, and the city's alleys and dumpsters. Their little firm, Organelle Design, has generated everything from furniture to a customizably insulated window prototype, but their most eye-catching creations are hanging lamps made from coat hangers-. Don't worry, they've got both kinds: wooden and plastic. Built around the rims of bicycle wheels and cast-off chainrings, their lighting designs are held together mostly with zipties, some with chicken wire.

Elizabeth Grossman Chases Toxic Molecules Through Our Bodies and Around the Globe

Thu, 08 Oct 2009 10:44:07 GMT

If, in the United States, you happen to decided you'd like to earn your PhD in chemistry, you may notice that at no point are you required to take a course in toxicology. This is partly the reason we're now being assaulted by a growing mob of dangerous substances as they float through our oceans and bloodstreams. So says science journalist Elizabeth Grossman whose new book, Chasing Molecules: Poisonous Products, Human Health, and the Promise of Green Chemistry, is a sleuth job into the world of synthetic estrogens, carcinogens, nanoparticles, and other man-made poisons that may be making us fat, angry, stupid, and dead.

Swiss brothers Markus and Daniel Freitag make their slick bags, wallets, iPhone cases, and other accessories from discarded tarps, the type used by long-distance freight trucks in Europe. Even their Zurich store is made from shipping containers. Recently, the two suave gents were recruited by a Vienna art gallery as part of Vienna Design Week to partake in "Urban Gardening," an art installation involving an active compost pile. Freitag supplied 100 limited edition compost bags to patrons on opening night on the promise that, for three months, they bring their food scraps back to the gallery to become part of the arty compost heap.

Meet Your New E-Waste Recycling Symbol: "4th Bin" Winners Announced

Fri, 02 Oct 2009 14:30:33 GMT

The iconic "mobius strip" recycling symbol that we know so well was designed by a 23-year-old in 1970; it was his submission into a design competition sponsored by the Container Corporation of America. Symbolic history may have just been made once more with the winners of the 4th Bin design contest. Valiant Technology sponsored the competition to design a logo for e-waste, as well as a container specially engineered to receive it, initially for New York City, then for the world. E-waste, or electronic waste, is an ever faster-growing category of trash consisting of computers, cell phones, game consoles, printers, etc. We've seen how e-waste creates toxic nightmares overseas, and how better recycling could recover a lot of cash. But many e-waste recycling programs are still disjointed or ad-hoc, and the 4th Bin contest is trying to make it a more recognizable part of our daily habits.... Read the full story on TreeHugger

The Green Future of Mercedes-Benz: The New Electric Smart Fortwo

Thu, 01 Oct 2009 13:25:20 GMT

Fully-electric Smart cars have been zipping around roads in various forms for some time. But now, Daimler AG, Smart's German daddy company, is ramping up to roll out the second-generation of its battery-powered Smart fortwo--this time taking advantage of its ace in the hole: a 10% ownership stake in Tesla Motors. The upshot will be a more powerful, longer-range EV that will be widely available by 2012. As you know, I've been writing about Daimler AG (owner of Mercedes-Benz and Smart) quite a bit lately (see my overview and S-Class hybrid test drive). My impression is that the company's green-technology ambitions are not well known in the US and that a closer inspection is worth while. Since it's debut, electric conversion enthusiast have loved getting their mits on the tiny Smart, which lends itself well to battery power. In fact, Smart claims the fortwo was designed with electric-drive components in mind from the very start, even when it was available only in gasoline and diesel models. Now, as the second-generation of the Smart EV gets ready to hit the assembly line next month, the Smart fortwo may be one a step closer to its true calling.... Read the full story on TreeHugger

The Green Future of Mercedes-Benz: Driving the S 400 Hybrid

I'm still buzzing from the Frankfurt auto show. With its many visual delights, the IAA is arguably the most important gathering of automakers in the world. Much of my focus centered around Mercedes-Benz (after all, Daimler AG was my host), and I'm still sorting through all there is to say about this company as it becomes a more and more important contender in the green car battle. Mercedes is now moving into the luxury hybrid market, a space that has been decidedly Lexus' up till now. While the S 400 hybrid has been a fast seller in Europe (accounting for almost 20% of S-Class orders since June), it has only just rolled into US dealerships. I test drove the S 400 on roads winding through cabbage and pumpkin farms outside Mercedes' home of Stuttgart, getting a good feel for this new luxury hybrid offering....

But after spending the better part of a week in Germany, talking with some of Daimler's top brass and taking in the Frankfurt auto show, it's clear to me there's a lot to discuss. The Mercedes-Benz brand is being steered towards a vision of zero emissions by way of an array of next-generation technologies. Hydrogen fuel cells, hybrids, plug-ins, battery electrics, and clean diesel engines are all getting heavy investment from the luxury car maker. The next few years will see some dramatic products offerings from the Mercedes-Benz and Smart lines. Here's a quick overview of the green car goings on over at Daimler....

A Modern Fixed Gear with 80s BMX Style

Fri, 25 Sep 2009 13:58:10 GMT

As a scrappy kid you couldn't keep your mind off your BMX--today, as a well-rounded hipster, you salivate over single speeds. If this is you, then your ship has come in. Bike-maker SE Racing and DC Shoes have melded their nostalgic brain matter to create a fixed gear bicycle that embodies the unmistakable 1980s glow a classic BMX, the PK Ripper. This aluminum-framed ride has a flip-flop hub (can alternate between single speed and fixed gear), a classic looptail rear end, "floval tubing," and--if I'm reading this right--a bottle opener built into its saddle. The Standard Hotel in New York caught wind of this retro sensation and picked up 20 of these PK Ripper fixies for its own. After being customized to its own liking (Standardized, if you will), 15 will be made available to patrons of the New York hotel for city jaunts. The other five are being sold through the Standard's online store ($1250). Via Highsnobiety... Read the full story on TreeHugger

I recently had the pleasure of taking two of Volvo's latest prototypes for some blissful laps around the test track in Gothenburg, Sweden. This is the first time Volvo has presented its all-electric C30, a technology still in the research phase, and I got a good feel for where the company's stands with its EV and plug-in hybrid projects. Seen in action in the video below is the BEV (Battery Electric Vehicle), based around the already-in-production Volvo C30. The car has a fantastic feel: tight handling, satisfying pickup, and a beautiful sound during acceleration. The car is outfitted with two lithium-ion batteries, one under the hood, the other beneath the trunk, giving the car a range of 150 km (about 93 miles). I also sampled a plug-in diesel hybrid, a technology that Volvo will bring to commercialization in 2012.... Read the full story on TreeHugger
