Philips Smokeless Stove Uses 80% Less Fuel, Saves Lives
by Lloyd Alter, Toronto on 03.15.06
Design /&/amp; Architecture (kitchen)
stove.jpgWe usually think of Philips as a maker of LCD's and LED's but they have been cooking up other things in Eindhoven, including this woodstove. 300 million families in the world's poorest regions burn wood for cooking, and smoke and toxic emisions kill 1.6 million people per year. When properly used the woodstove typically reduces fuel consumption up to 80% compared with traditional, three stone fires. Apart from faster and more convenient cooking, this energy efficiency means the stove can save the cost of the time needed to gather fuel, and should also slow deforestation. According to Philips: "The secret to many benefits of this stove is an electronically controlled fan forcing air through the stove, leading to higher temperatures and a better fuel to air ratio. This results in cleaner burning and more efficient use of fuel. A thermoelectric generator using the heat from the burning wood generates electricity for the fan. Apart from ensuring autonomy from electricity supplies, the generator can also power external equipment like radios or lighting." That's good green design. ::Philips via ::FreshGadgets

imagine what one can accomplish for the environment if this were partnered with a solar oven and/or even just a simple haybox - preferably more than one!

So, smoke and toxic emissions from cooking fires kill 1.6 million people a year? That is complete and utter BS. Do you guys ever check a "fact" before you print it?
LA: You might read the Philips link. You might read the PDF of a scientific study here.

I read the above paper at the Philips link, and the conclusion that the authors came to is: There is a relationship between CB and COPD and the use of biomass fuels in rural areas of central Turkey. Which seems to support the above fact about 1.6 million people dying. I have in fact travelled in various places around Africa and indoor cooking fires are definitely a concern. Check out the following links to find that the WHO and the nation of China are pretty concerned about the issue...

A similar product, the Sierra Zip stove (http://www.zzstove.com/sierra.html), has been available for years and is sold for about $60 through Campmor (http://www.campmor.com/webapp/wcs/stores/servlet/ProductDisplay?productId=13930). Only requiring an AA battery for hours of use, an inexpensive solar charger could make this a readily available alternative to Phillips’ design.

A similar problem exists in China. People use coal in small poorly designed stoves. Sometimes the gap between the wall top and roof eave serves as the vent flue, which results in continuous exposure of the inhabitants to sulferous oxides,ash, and PAH's. Worse, Chinese coal tends to have very high levels of mercury lead arsenic and flouride, so much so in some regions that food flouride poisioning is a serious public health issue.
Benjamin Franklin was inspired to develop his "Franklin Stove" though his experiences with terrible fire place designs. He wrote humorously about how he could tell how bad a person's fire place was made by the extent to which he/she smelled like a Virginia Ham. There are several reasons why the avearge life span of North Americans increased steadily from the Civil War on: one of these reasons was the improvments made to cooking and heating system designs!

This doesnt really solve one of the bigger problems of wood stoves: deforestation. Granted, this stove requires less wood, but it still uses it. I also dont see people who need to use wood stoves because they cant afford anything else spending money on this product. Its a good idea, but i fear it doesnt really make the problem less of a concern.

This is a great idea! I believe that it has the potential to change the face of third world countries. Unfortunately, as I have found out from past experience, a new way to burn fuel isn't necessarily the answer. In the United States there are good and decent people who are burning pallet material for firewood. As more people are learning this wood is reeking with toxins including arsenic. Recently, I was buying a Christmas tree with my kids when I say the black smoke eminating from the burn barrel nearby with a pile of broken commercial pallets nearby. After explaining the danger there response was that of interested disinterest, continuing to burn pallets long after we left. Education is the key regardless of the country.

Pee-Cycling: Green Toilet Idea From Olde Europe
viking_ship_toilet.jpgAs we've already posted on poo-cycling today, might as well take in the whole excretory panorama. According to an article in New Scientist:- "Despite making up only 1 per cent of the volume of waste water, urine contributes about 80 per cent of the nitrogen and 45 per cent of all the phosphate. Peeing into the pan immediately dilutes these chemicals with vast quantities of water, making the removal process unnecessarily inefficient". That's certainly true. But there's a "downside" to the design solution being presented. Young tree hugger males will have to sit on the pot to do their "pee-cycling" ....

Milwaukee Closes The Loop On Poop
40lb_bag.jpgWe recently learned from Lloyd about a proposal to wrap a natural gas-fired, generator proposal in “green†by adding solar photovoltaic capacity to the project. The Milwaukee Wisconsin USA, Metro Sewer District has a project in mind that seems more straightforward in intent and practical in outcome. Via the Milwaukee Journal Sentinal:- “Solar energy would provide nearly all of the electrical power needed to transform sewage sludge into Milorganite fertilizer at the Jones Island wastewater treatment plant, under a proposal by the Milwaukee Metropolitan Sewerage District.Four rows of photovoltaic panels would be installed atop the roof of the Milorganite plant this year at a cost of $198,000 if the proposal is approved this month by the sewerage commission…The Milorganite plant would become nearly 100% self-sufficient for electrical needs, depending on cloud cover, if the solar panels are installed…â€...

Vintage Magazine Notes from Fake Forest
fakeforest.jpg We love these vintage magazine notes from Fake Forest. Each set includes 10 sheets of recycled paper and 5 window envelopes. The envelopes are 100% post-consumer and made from popular periodicals like LIFE and the Saturday Evening Post from the 1950s through the 1980s. The creators of these notes buy from a variety of garage sales, thrift stores and magazine warehouses so each is an authentic souvenir from the days of early advertising. No computer printing or scanning is involved and each is hand selected making no two envelopes alike. The writing sheets are printed by an offset printer using “direct-to-plate†film-less technology without photographic chemicals. Even the packaging is low impact with a 100% biodegradable cello bag, a recycled label, non-toxic adhesives and soy-based inks. The notes can be found at BTC Elements for $9.00 (and is apparently one of their most popular items). ::Fake Forest...

TreeHugger Picks: Furniture Designs Worth Another Look
th-picks-drool-worthy-furniture-design.jpg Part of TreeHugger's mission is to find and promote ideas, products and designers that are doing great work but still flying below the radar. We've published a couple of focused projects, like our Best of TH: Designers (parts one, two, three /&/amp; four) and Sneak Peek series leading up to HauteGREEN last year, that covered a lot of ground; still, there are lots of sustainable designs and designers who deserve a thumbs up. Here are some picks for furniture designs that deserve another look. 1) We like David Brunicardi's suave, hand-made pieces enough to feature him not once but twice. 2) The same goes for Modernlink, whose Hudson credenza and Ryder entry table have grabbed our attention. 3) Brent Comber's modern, elegant furniture ranges from the simple Denta stool to the playful, dynamic Alder bench series. 4) PIE (that's Project Import Export) builds hand-crafted furniture and accessories that are designed to imitate nature; the curvaceous h Chair exemplifies how their design brings warmth and sensuality to modern furniture. 5) Moxbox's Boopop coffee table shows how their designs are all about merging: geometry with art, balanced shapes and eye-catching splashes of color, bamboo with bamboo....

Wallpaper* Magazine January 2007: Less but Better
wallpaper-jan07.jpgThe message behind January's Wallpaper* magazine is loud /&/amp; clear: "Less but Better". The cover, the latest in a series of limited-edition designs, is by German architect and industrial designer Dieter Rams, and its a philosophy he's been pushing for awhile. And Wallpaper* has discovered that it's spreading: "Now, others – particularly in furniture design – have taken it onboard in terms of environmental responsibility and are looking at ways of producing sustainable design that works well, looks good and makes sense. Environmentally responsible doesn't have to mean horsehair shirts and dirt-covered vegetables. It can manifest itself in cute, clever and highly desirable forms. Today we just need to take time to invest in fewer of the right items, rather than throwing away more of the wrong ones." Wallpaper* prides itself on revealing the best before it reaches the mainstream, so if they're forward-looking thoughts turn out to be prophetic, the design world at large will only get greener from here. As for the rest of the magazine, sprinkled among Dolce /&/amp; Gabbana's new restaurant in Milan, waterfront architecture in Dubai and the rest of the best in modern design are a few quick mentions of what they describe above. Japan's Natural House organic supermarket chain, and specifically the natural cosmetics /&/amp; skincare (page 034) gets a mention in the "Grooming /&/amp; Beauty" selection, and Ringtons' organic herbal tea (page 047) is lauded for their new brand identity that heralds a new era for the company. Even the clever Lamp/Lamp, which we mentioned before, gets some attention (page 049) as the mag takes a peek at what's new in Japanese design. To start with such a compelling cover and then peter out when it comes to content is sort of like having a fabulous dessert first followed by an ordinary meal, but that doesn't mean that we like the dessert any less. ::Wallpaper*...

Geodesic Domes Gain Weight and Settle Down
dome2.jpgHow could we call ourselves treehuggers and not cover this- the rebirth of every hippie's dream, the geodesic dome. However Bucky himself might have trouble recognizing these- he thought of them as light, elegant structures that were built out of a minimum of materials, not bombproof concrete. Treehugger hero Jay Baldwin says that when he worked with Bucky, the domes were rarely more than a standard 24 feet in diameter and cost less than $1,000 to build. Not any more: “The domes have gotten bigger and more expensive as people’s incomes expanded,†said Dennis Johnson, who founded Natural Spaces Domes. “They want another bedroom,†said Robert Singer, the president of Timberline Geodesics, a dome manufacturer in Berkeley, Calif. “They want the home office, they want the entertainment room, they want the extra space in the basement, they want the large custom kitchen.†Jay thinks they are bastardizations of Fuller's concepts. “I call them elephant droppings,†he said. “Fuller’s idea was that of a machine-made object, a pure geometry.†::New York Times...

Sven Table Lamp: Another LED Beauty from Lucesco
sven-led-table-lamp.jpg As any regular reader of TreeHugger knows, we are big fans of compact fluorescent bulbs: they're a quick /&/amp; easy solution for energy efficiency in the home, but they'll ultimately lose out to LEDs' superior efficiency and longevity. While CFLs have been around for years and are readily available, LED lamps are just starting to appear with regularity in the lighting marketplace; the latest one worth a look is the Sven Table Lamp, manufactured by Lucesco. Like the Mix LED desk lamp from Luceplan, Sven is a stylish, modern light source that's height adjustable (14 - 17 inches). It employs 40 LEDs that draw 22 watts, and with a design that keeps the LEDs cool, has a life expectancy of around 50,000 hours (that's about 20 years at 40 hours/week). Though the Sven Table Lamp isn't exactly price competitive with many other non-LED implementations, $475 (at Design Within Reach and UnicaHome) might just be worth it for 20 years of worry-free, efficient lighting. It's available in black and white; according to the UnicaHome site, red might be coming soon. ::Sven Table Lamp via ::Apartment Therapy...

House /&/amp; Garden February 2007: "Eco Chic"
housegarden-eco-chic-feb2007.jpg This month, House /&/amp; Garden magazine takes the green lifestyle for a test drive with a couple of interviews and articles featuring some of the best in TreeHugging design and ideas. They hang out at home with Paulette Cole (page 15), leader of ABC Home (whom we've featured here, here and here), who walks her store's talk with quips like, "An Inconvenient Truth is like my bible. It informs my daily choices from conscientious consumerism to carbon neutrality. I only bring organic food and cleaning products into my home." She's also a big fan of compact fluorescent bulbs and biodynamic wine (watch our TreeHuggerTV episode about earth-friendly vino here). There's also "20 Ways to Live Green" (page 29), an "Eco Chic" feature with products, tips and resources for making your home and your life blissfully green. While there isn't a whole lot that TreeHugger hasn't seen before, it's a pretty good cross-section of stuff, people and ideas, from Clint Eastwood's "Tehema" development to Method cleaning products, WorldChanging's book to IKEA's PS collection and Odegard rugs to Q Collection's furniture. They also tracked down sustainability guru Bill McDonough at his home in Virginia for a quick q /&/amp; a (page 35), where he talks about the cradle to cradle concept, making a greener home, and the new ideas that excite him most. House /&/amp; Garden also has some of the better web support for its print mag out there; there are more green tips on the site, and, in support of the green living ideas, TreeHugger will be providing a tip each day this month in our HG blog.

LEED Renovations: What's Old is New Again
greenreno.jpg LEED for renovations is not as widespread as LEED for new, but it is gaining in popularity. There are so many things one can do to make an old building healthier and more energy efficient; much of them have to do with taking the building back to its original form. For example in this picture one can see that there are terrazzo floors and no suspended ceilings, eliminating major dust catchers. Older buildings were built with high ceilings and high big windows to maximize natural light; energy was expensive and there was only incandescent light when they were built. Windows were double hung with top and bottom panes moving; Georgian English builders learned that double hung windows create a convection current that brings fresh air further into a building than any other kind. When it comes to healthy, efficient buildings, what's old is new again. Read about a project in Seattle in ::New York Times ...

Downloading Designs: Our Home Becomes Our Factory
readymech.jpg Dematerialization is a trend- the transport of things that used to be physical and now are bits and bytes downloaded and processed. The iPod is an early example; it integrated our computer, the internet and a convenient, well-designed device to bring music to us without the physical intermediary. We loved the downloadable pinhole camera that demonstrated the possibilities of downloading 3D technology and putting it together; we have droned on about flatpack made-to-order local furniture. Now we are beginning to see talented designers producing things that we can download and make at home, shortcircuiting the entire expensive production, transport and sales process that consumes so much energy. An example of what is coming down the pipe ( in the very near future ) are these designs that you can download and assemble yourself. (We were going to start with the fantastic Cardboy calendar, but the designer has determined that it is "sold out") So we will go straight to Readymech. ...

Tivali Kitchen from Dada
dada-tivali-kitchen-mono-block.jpg I may well start calling myself a Dadaist if they keep turning out things like this. We show designs for small spaces on TreeHugger because they show how we might live very well with less; this kitchen design works as a room divider, and has doors that make it completely disappear. The website showing it is in Italian, but design site Trendir says "Designed by Dante Bonuccelli the Tivali features dark wooden doors that smoothly glide away and neatly disappear into storage slots. Steel fronts reflect the bright blue light from the illuminated glass shelves, broadening the mono-block kitchen space. Suddenly the kitchen basin, oven and range seem like a spacious workspace where everything is in reach. By adding the optional fridge column the Tivali incorporates every cooking need from start to finish."...
