Smaller, Smarter Inverters Equal Cheaper Solar, Greater Efficiency
One the largest hurdles to people and businesses embracing solar energy is the cost. The panels themselves make up a great deal of total expense, but there are also additional components to consider to get that energy working with your home. The most common accessory to any good solar installation is the inverter. This piece of equipment converts the solar panel’s DC energy to AC. A new firm called Enphase Energy hopes to remove this cost and produce micro-inverters; so small that each panel will receive their own. From the article,
City Sues Man For Reducing Waste, Cancelling Garbage Pickup
53 year-old Eddie House was proud of his efforts to reduce his waste. Being concerned for the environment, the single bachelor found that his sustainable habits left him with near-zero garbage. With nothing left to throw out that couldn’t be recycled or composted, he did what any individual might do to go the next mile: canceled his garbage service. As a reward for reducing his impact on the planet, House received a lawsuit from the San Carlos Deputy City Attorney claiming he was in violation of not maintaining garbage service. Wow. From the article,
The lawsuit claims House broke the city’s municipal code requiring all residential, commercial and industrial properties to contract with Allied Waste for pickup at least once a week — a standard requirement in most cities, San Carlos Deputy City Manager Brian Moura said. “It’s just me and my dog, so I don’t have a whole lot of garbage to begin with and I recycle everything,” he said.

National Geographic has a story about how the West in America is going to dry up in the future. Turns out the past 100 years is the especially wet period for this area, not the norm. That spells trouble for a lot of people, depending on how dry it might get.
Football player Tony Gonzalez has gone Vegan. That’s a big boy.
Treehugger has a survey up asking readers how they are planning to spend the rebate checks, if we get them. You should vote in it. The Green Options network also has a story about the stimulus package. I have yet to meet anyone who is going to spend it on much more than a small amount of things.
Our opinion on what you should do with it? Use it bulk up your food savings. Pick up some large packages of beans, rice, wheat and other supplies so you won’t be unprepared in the future. After that, look for cheap ways you can raise the efficiency of your house. Insulation, making rain barrels, starting a garden. Whatever you do, don’t go buying a plasma TV. If that’s one of your choices just save it, which you could do anyway.
The Green Roof Dog House Roof!
While your busy making all those cool green upgrades in and around your house, don’t forget that your four-legged friends might also want a piece of the action. Well, at least that’s what one company called Sustainable Pet Design believes. They’ve introduced “Green Roof Animal Homes” that ‘smell good, grow plants, attract butterflies, filter water, insulate, and repeal fleas naturally.’
Each home is custom-built and uses only non-toxic materials, including untreated red cedar planks, zero-VOC paint, and beeswax waterproofing. All vegetation for the green roof is native to the region you live in.
Pretty cool idea — and something nice for those that would prefer not to take a hands-on approach. Otherwise, we’re pretty sure creating something similar wouldn’t be too difficult for the novice carpenter inside you. You might even be further encouraged to take that path when you see the starting prices for an extra-small green doghouse are just around $1,000. Want a really cool big one? $6K.
Makes me glad I have a porch for my pooch.
Green Roof Proposed For Stretch Of California Highway
This sounds like a wonderful idea — if anyone happens to have $200 million lying around.
A plan has been submitted to cover a stretch of California highway with a 24-acre park. It would be built on a deck constructed over the below-grade portion of the Hollywood Freeway (US-101). Organizers argue that by placing a “cap” over one of the world’s most congested freeway systems, the necessary ventilation system would clean the air before re-circulating it back into the environment — creating a positive improvement in air quality for LA. Additionally, the park would also provide a nexus between East Hollywood and Central Hollywood–”alleviating the strain on the community from the initial creation of the freeway through this section of Hollywood.” From the site,
Ducted Wind Turbine Provides Efficient Rooftop Energy
A company named Marquiss Wind Power has successfully finished raising $1.3 million for development of its Ducted Wind Turbines. Unlike their much larger counterparts, ducted turbines are boxy and stand about 19ft tall. Despite what appears to be aerodynamic disadvantages, this shape actually allows the turbine to re-orient itself according to the direction of air flow; something that can be a bit random in urban centers. The ducting is intended to increase wind speed as it approaches the blades. According to the website, these factors combine to allow the power output from the MWP turbine to exceed that of any traditionally designed comparable turbine. From the article,
At the moment, two models are sold — one intended for areas with wind speeds of 6-10 mph, and another for higher average speeds. The turbines are intended for buildings between one and three stories tall.
It sure ain’t elegant — but there’s a lot of science at play with this design. I especially like that AeropointT500 can operate in low wind speeds. I have no ideas on price — but hopefully that $1.3 million will go a long way to fleshing this product out a bit more.
Monsanto Releases Another Genetically Engineered Beast on The Earth
A news story today discusses Monsanto and how they have obtained approval to release a genetically engineered sugar beet onto the market. You’ll be shocked to hear that the beet has been modified to live when Roundup is sprayed on it.
From the article:
“The law requires the government to take a hard look at the impact that deregulating Roundup Ready sugar beets will have on human health, agriculture and the environment,” said Greg Loarie, an attorney at the Earthjustice law firm, which is helping represent the plaintiffs. “The government cannot simply ignore the fact that deregulation will harm organic farmers and consumers, and exacerbate the growing epidemic of herbicide-resistant weeds.”
The Air-Powered Car Finds A Future Home In India
Viva la France! French engineer Guy Nègre has been working on the concept of an air-powered car for the past 15 years. Thanks to a new contract with India’s main car manufacturer, Tata Motors, Nègre’s technology is about to reap the benefits of a major corporate backer; not to mention access to a massive, growing market. Geeks Are Sexy lays out the details on the tech,
“The principle that makes this car work is very simple. Instead of using gas to create an explosion and make the pistons move, the vehicle’s engine is powered via three compressed air tanks located under its chassis. Environmentally speaking, this means all that goes out the exhaust pipe is cold, pure air, which can even be used as an air-conditioning source on a hot summer day.”
Philips’ 42-inch Eco TV Is Perfect For Your Off-Grid Home
It doesn’t come in green, but Philips’ new 42-inch Eco TV is certainly sporting some earth-friendly credentials.
Announced at CES 2008, this television is packed with power-saving features; something a few of my off-grid friends might find interesting when considering their next (or first) television. From the article,
“Chief among them is the ability to dim the backlight–by up to five times peak brightness–in response to program material, much like the “local dimming” found on Samsung’s LED-based LN-T4681F. Dimming the backlight in darker scenes has the dual benefit of saving power and improving black-level performance, according to the company. The backlight can also be dimmed via a room lighting sensor, so in dark rooms it will use less power. There’s also traditional a “power-saving” mode that caps the peak light output.”
The Cup Lasso Turns Water Bottles Into Appealing Vases
I always enjoy creative fixes to environmental eyesores. Take for instance this concept for a slip-on cover made from wool felt for water bottles. Called the Cup Lasso, it effectively turns what might otherwise simply be recycled into a suddenly useful and appealing vase for flowers. Nice, right? The concept comes from Orcadesign’s “GreenHouse Effect” project — which explores 10 concepts for eco-friendly living with aesthetic appeal.
Flat-Pack Eco Speakers Made With 100% Recycled Materials
We’re not sure how great these speakers sound, but the environmental thought and design that went into them is certainly laudable.
They’re called Eco Speakers and are made from 100% recycled materials. They even fold flat — which is how they’re packaged. For $15, you can’t go terribly wrong — although since the company did not have any demo units out on the floor at CES, we might retract that statement.
New Solar Collector So Efficient It Works At Night
While we’ve seen solar cell efficiency squeak past 40% in labs this year, we’re still stuck commercially with panels that at most convert about 20% of what hits them into energy. Then there’s the whole “darkness” thing that cuts into production for part of the day.
Researchers at the Idaho National Laboratory have potentially solved both issues by turning to another hot field: nanotechnology. From the article,
With this new technology, millions of extremely small twists of metal are molded into banks of “microantennas”, which can be placed on almost any material, including plastic sheets. These spiral shaped “microantennas” are about 1/25 the width of a human hair. They are so small that they resonate from the interaction with the sun’s infrared rays. This resonation can be translated into energy. During the day, the Earth soaks up a lot of this infrared energy, which is then radiated out at night — enabling these microantennas to collect power even after the sun has set.
The Roots Of Freeganism Part I: Food Waste
Freeganism, the philosophy of non-participation in the capitalist economy through minimization of what one buys, has been getting heaps of press lately, with outlets as high-rolling as the New York Times and the Washington Post running pieces on the subject. But while much recent media coverage focuses on what it’s like to live as a freegan, I’m interested in the forces that freegans are reacting to, and the realities that allow them to sustain their lifestyles. In this four part series, I’ll be examining these questions by looking at food waste, disposable culture, modern work, and the state of community in America.
One night in late November, in the courtyard of a community center in Bushwick, Brooklyn, a bread mountain was constructed. It measured about four feet tall and 10 feet in diameter, the product of a few nights of dumpster diving throughout New York City. Hundreds of rolls, pumpernickel loaves and baguettes lay stacked in various states of edibility, but like so much wasted food in New York City, they would never make it to the people that needed them most.
Growing Power-An Urban Agriculture and Education Center
A few friends of mine from the fledgling Sustainability NPO we recently founded, Sustain Jefferson, spent a few incredible hours touring Growing Power this past Monday. Growing Power is a non-profit Urban Agriculture and Education facility in Milwaukee, WI that claims to grow enough food for 2000 people on 2 acres. With a claim like that I was drawn like a moth to flame. Their website offered some clues to their system-vermiculture, aquaculture, and several greenhouses. The actual tour filled in many of the details and inspired me in a way that I haven’t experienced since I was originally introduced to Permaculture and Bill Mollison several years ago.
What excited me most about Permaculture was the sheer common sense of it all. Taking wastes and turning them into resources is not something we typically think of today. Just as Forests have no waste products, Permaculture strives to promote such perfect systems in human endeavors whether it be designing a garden or linking businesses together via Natural Capitalism. Using the waste of built systems to add energy to another allows you to drastically reduce your time and energy taking care of problems and reap the benefits of one integrated system working in concert is something that continues to fascinate me Aquaponics, especially in the uber simple system that Will Allen of Growing Power sets up, fits the bill perfectly.
Green Ideas We’d Like To See: The Wind Shade Roof
Architect designer Michael Jantzen has created a green oasis of sorts with his wind shade roof concept. Basically, it’s a large oval roof clad in wind turbines that powers whatever is under or around the structure.The particular roof in these concept photos is shown covering a large swimming pool. The integrated turbines would provide power for night lighting, pool maintenance, pumps, temperature control, etc. These would also make really cool pavilions, say, for farmers markets or other functions.
Eco Sac: The Water Bladder For Your Home
If giant rain barrels aren’t aesthetically pleasing or you lack the room for installation, you may want to consider the Eco Sac; a flexible rainwater bladder storage system that hides away under decks or floors. Each sac is manufactured using “industrial strength fabric sealed by high frequency welding.”
According to the site, the eco sac is better than your average rain barrel because a.) it captures water faster than rigid tanks, b.) you can use multiple bladders which all fill at the same rate and at the same time c.) it is guaranteed not to leak and d.) it is algae resistant and the water stored is potable.
Pretty cool idea for those with limited space to capture rainfall. There are 54 different sizes to choose from, ranging from 2,200 liters to 8,600 liters. Apparently, you can join multiple sacs together to get up to 50,000 liters or more water storage.
Much like the portable grey water recycler we wrote about earlier this week, this product is currently only available in Australia. Something tells me however — with the water woes currently affecting parts of the U.S. — that we’ll be seeing more of these stateside shortly.
Best Of Both Worlds: The Bluenergy Solar Wind Turbine
A German company has created what appears to be the first integrated solar vertical axis wind turbine. Obviously, the advantage here is that when one resource isn’t available, the other may still come through to help produce some energy.
The company, Bluenergy AG, based their design on sailing engineering. The wind rotor is rotated by two spiral-formed vanes. According to the site, the installation costs relatively little, produces no noise or significant shadowing, and can be easily maintained from ground level. It also appears that the vertical wings can be lowered horizontal for access as well. One interesting design highlight claimed by the site is that the solar cells are cooled by the rotation of the turbine and thus generate more electricity. Anyone know if this would add significant output?
One Trillion Reasons To Invest In Clean, Green Energy
U.S. Bank Morgan Stanley has estimated that global sales from clean energy sources such as wind, solar and geothermal power and biofuels could grow to as much as $1 trillion a year by 2030. In the meantime, the market may hit $505 billion in sales by 2020 — almost 9 times the level in 2005. Not a bad idea to invest, right?
Well, maybe. While it’s a sure bet that renewable energy will grow in percentage sales of global energy sources; there’s no telling how rapid or sustained such growth might be. Morgan Stanley was clear to indicate that current numbers are based on bullish investments, the rising value of oil, and current worldwide concerns over global warming. A change in any number of these factors could affect the industry. From the article,
Blog Action Day: The Pig Farmer
One of the stories that should circulate the “green” blogosphere, and be posted on everyone’s site. I usually skim longer posts, but when I realized the heart and depth of the writing, I took the time to slow down and read a truly wonderful and heart-wrenching story.
From Celais, by John Robbins:
One day in Iowa I met a particular gentleman—and I use that term, gentleman, frankly, only because I am trying to be polite, for that is certainly not how I saw him at the time. He owned and ran what he called a “pork production facility.” I, on the other hand, would have called it a pig Auschwitz.
The conditions were brutal. The pigs were confined in cages that were barely larger than their own bodies, with the cages stacked on top of each other in tiers, three high. The sides and the bottoms of the cages were steel slats, so that excrement from the animals in the upper and middle tiers dropped through the slats on to the animals below.

But eating local is so expensive…
Really? Here is a picture of a few things I picked up yesterday. 6 butternut squash. 1 hubbard squash and 15 pounds of sweet potatoes. Set me back $29.
The ad flyer for my local grocery store lists butternut squash at $.49 per pound. I have 27 pounds in my pictures. That works out to $13.23 for the squash. (No comparison for hubbard’s so I included it with the butternut squashes)
In the same ad sweet potatoes are listed at $.69 per pound for a total of $10.35.
Total cost at the store is $23.58. Total cost from the farmer is $29. The difference is that in my case the farmer got the entire $29 instead of a wholesale percentage of the cost.
From the same farmer I also have on order 75 lbs of potatoes. They’ll cost me about $30. That works out to $.40 a pound compared to a sale price in the ad flyer of $.26.
Maybe it’s just me, but I’ll gladly pay that slight premium for fresh local foods that support farmer’s more. The squashes I purchased had just been picked yesterday morning. Now that’s fresh!
