This trio of
human-powered dresses convert kinetic energy from movement into electricity.
A
solar-powered, vintage-inspired brooch might appear to be a design contradiction, but this subtle stunner is still a winner.
Made from
recycled cassette tape, these nondescript-looking ties can be "played" when you run a tape head over them.
Clothes that
generate heat from your sweat? Jimmy Carter would approve.
Timbuk2's new
solar-panel messenger bags are almost too cool for school, but they'll turn into a lantern at night if you need to hit the books after dark.
Made from recycled soda bottles, Zegna's
solar-powered jacket can power an iPod or cellphone without making you look like a dork.
After harnessing power from the sun, the tiny LED bulbs on this
photovoltaic-cell necklace light up like a string of pearls.

From
WeeHuggers dressed up as trees to a jack-o-lantern carvings of butterflies, bees, and one of three men raising a wind turbine--much like the
Raising the Flag on Iwo Jima--readers sent in their green Halloween photos from Copenhagen, Canada, and here in the States. And if you missed last week's
Readers' Photos it's not to late to enjoy our action-packed
Readers' International Day of Climate Action Photos slideshow.

...

A lot happened this week in green: from readers in the Hollywood Hills to our writers in Times Square, the International Day of Climate Action brought global awareness for climate change; we found out Chinese fruit bats demonstrate unusual sexual behavior--never before seen in adult animals--discovered a lamp that works only with a drop of blood, and rounded up five tips for a greener Halloween. Find out what else happened in the world of green this week in our photo roundup of most popular, most important, and most oddball stories. And if you missed it, view last week's
The Week in Pictures: Elephants Extinct by 2025, Great Pacific Garbage Patch, Green Home Improvement, and More (Slideshow).

True to its name, the
Whatchawant is whatever your child wishes it to be.
Can't decide between a rocking chair or a rocking horse? This traditional
Baltic rocking chair horse does it all.
If you're short on space, the
Tori Foldable Rocking Horse can be packed away after your tot has ridden into the sunset--for the day, anyway.
This
rocking "Pizzly" bear keeps up with the climate-changing times by fusing grizzlies with their polar brethren.
The aptly named
Giddyup Rocking Stool uses actual reclaimed leather saddles for an authentic, home-on-the-range touch.
Why should kids hog all the fun? Here's a
rocking horse for the young at heart, if not in years.
Plan Toys' Walking Elephant bucks the rocking-horse trend with a tiny, mobile pachyderm.

"The Boy Who Harnessed the Wind"
To most of us, old bicycle parts are mostly good for
DIY furniture projects if they're good for anything, and
windmills are best designed by people with advanced degrees.
When fourteen-year-old William Kamkwamba, of Masitala Village in Wimbe, Malawi, stumbled across the image of a windmill for the first time while pouring over a
library book, he wasn't thinking like that. He was thinking of his village's lack of electricity (only 2% of Malawi is electrified) and of how electricity could power an irrigation pump, which would help his family and others cope with meager crops. If you've
been reading TreeHugger, or any news really, you probably know what happened next......

Today's printing and writing papers commonly have 20-30% recycled content. For fiber packaging materials, 60 to 100% recycle content is typical. It took decades for industry to reach those levels. Can you imagine what would happen if the paper industry had to price-compete against oil companies for waste paper feedstock? Recycled content of all manner of papers would surely decrease. More virgin forests would have be cut to make up the difference, whenever ethanol demand spiked. Singled-minded researchers from the National University of Singapore seem to have conveniently overlooked that predetermined outcome....

Insulation can be so confusing. Batt or spray? Denim or foam? How much is enough? Where do you put it? Many of the so-called experts don't even know for sure. We try to explain in our new Green Materials Guide on Planet Green.
This is a work in progress; we will be adding more. But have a look at our
Green Materials Guide....
International Day of Climate Action in the Hollywood Hills. Credit: Vanessa Ryder
From readers in the Hollywood Hills and students at Stellenbosch University in South Africa who posed for a 350 photo-op to TreeHugger writers who formed the number five in London's South Bank and rallied in a climate change march in Fayetteville, Arkansas, global citizens participated on a grand scale in support of
350 and the
International Day of Climate Action, Saturday, October 24, 2009. Check out awe inspiring photos and keep checking back we'll be updating this slideshow, click through to submit yours.

From the news that all 600,000 African elephants will be extinct by 2025 at current rates of poaching, according to figures from the
International Fund for Animal Welfare, to Congress' approval of a bill that will allow three wheelers to get funding from the Department of Energy, a lot happened this week in green. Our
Best of Green winner
Chris Jordan visited the Midway Atoll, right in the heart of the
Great Pacific Garbage Patch and photographed sobering pictures of albatrosses stuffed with plastic detritus, Christine put together a slideshow of creatures found in the world's most powerful
tidal maelstrom, and readers sent in their green home improvement photos for our weekly slideshow. Find out what else happened in the world of green this week in our photo roundup of most popular, most important, and most oddball stories. And if you missed it, view last week's

How do you ask your best friend where her food came from? Ever tried to become a family of locavores for a week? Bloggers share stories of
helping loved ones to eat more locally.
Natural, DIY moisturizing face mask recipes always seem to demand the sacrifice of a delicious avocado. Then I stumbled across
one made from bananas. Perfect! I hate bananas!
How to kill a turkey, forage for fresh clams, and get organic, local lunches in schools:
three awesome experiments in green food.
We keep hearing "shop your closet," but what does that mean, exactly? What to keep, what to toss, and how to create a smart, lower-impact and stylish shopping list this fall/winter:
a step-by-step guide.
As I prepare to move but not yet knowing where my next home will be, I'm thinking about what I will put into storage and what I will let go of. And I'm seriously contemplating a radical idea:
giving it all up. All of it. Living with only what I need to keep to work, pay taxes and avoid public nudity charges.
Imagine posting a wish list for veggies or getting paid in pears:
veggie trading, produce exchanges, and other delicious ways to avoid wasting food.
Climate Action Day on October 24 is the last chance to bring awareness before the final climate meeting in Copenhagen in late December. Here's what you can do.

The
2009 Solar Decathlon, the biennial solar architecture competition held in Washington D.C., had us all abuzz last week. Here are some of our highlights:
We have a winner! Team Germany's
two-story solar-powered cube took home the gold--find out what made it tick.
Appearances can be deceiving: The
University of Illinois' Gable House, which won second prize, is anything but rustic.
Judges praised
California's Refract House not only for "breaking out of the box" but for successfully marrying interior and exterior spaces.
Feeling chilly?
Team Ontario's North House is designed to generate more energy than it consumes.
Compared with the average $490,000 cost of the other entrants, Rice University's $140,000
ZEROW House is eminently affordable.

Inhabitat for our full coverage of the
Solar Decathlon.

Trudie Styler is many things - a
UNICEF ambassador, a human rights
activist, a co-founder of
Rainforest Foundation and, of course, the wife of the musician
Sting. In September, she came to the big screen (or more likely to a smaller independent theater screen) in the film documentary
Crude. The film chronicles the case of Aguinda vs
Chevron-Texaco - a legal drama that is trying to find justice for a group of indigenous people in Ecuador that has had their homeland devastated in the name of drilling for oil. Infamously called the
Amazon Chernobyl, the movie examines the complexity of international conglomerate corporations relationship and responsibilities for environmental peril and human suffering. Treehugger had a change to speak with Styler about her work within
Ecuador and find out how she's helping make a bad situation better.

From an insulated attic cover to a pocket door -- which created an air lock between the front door and living space -- readers sent in photos of their energy-saving
home improvements and
green renovations. Click through for photos of an old Victorian house in downtown Stratford, Canada, renovated with
VOC-free paint and FSC-certified wood, an entire house wrapped in
Exterior Insulation and Finish System (EIFS), and a solar array atop a deck built with hardware store materials. If you missed last week's
