PARK(ing) Day 2009 is Tomorrow (Sept. 18)

PARK(ing) Day is all about making the city a little greener by taking a parking spot for a vehicle and converting into a parking spot for people. You can make it happen in your own city!

The PARK(ing) Day website has more information.

PARK(ing) Day began in 2005 when Rebar, a San Francisco art collective, converted a single metered parking space into a temporary public park in an area of San Francisco that is underserved by public open space.

Back then the project was named simply PARK(ing), and was devised as a creative exploration of how urban public space is allocated and used. For example, up to 70% of San Francisco’s downtown outdoor space is dedicated to the vehicle, while only a fraction of that space is allocated to the public realm. Paying the meter of a parking space enables one to lease precious urban real estate on a short-term basis. What is the range of possible activities for this short-term lease?

Since 2005, the project has grown into PARK(ing) Day, an annual worldwide phenomenon, created independently by groups of artists, activists and citizens. Along the way, Rebar has been supported by several non-profits that share our values and concerns about how urban space is used. PARK(ing) Days in the past would not have been possible without support from The Trust for Public Land, Black Rock Arts Foundation and Public Architecture.

Good Posture for a Good Life

Your mother was right, you should sit up straight. A new study has been done that examined how your posture when sitting affects your self-image.

Read about the posture study here.

Brinol et al. (2009) divided 71 students into four groups, then fed them a cover story about why they had to adopt two different poses: half slouching, the other half sitting up straight, chests puffed out. These two groups were then split again, and half were asked to write down three positive personal traits, the other half three negative personal traits.
…
The results showed that people who had been sitting up straight were much more likely to believe the positive things they’d been writing about themselves, whereas those who were slouching weren’t so sure. Meanwhile a doubtful posture had very little effect on the half who were thinking negatively about themselves.

5 Things to Make the World better Everyday

Everyday you can make the world a little better by doing very small actions. The more people that do small things can add up to a very large movement – so join in on the fun 🙂

Read the list of five things you can do here.

Don’t throw it away! We have a tendency not to think about items we throw away. They disappear from our sight, so they are out of our minds. But all those things that the garbage truck hauls away every week do have to go somewhere, and that place is a landfill. Landfills are a major cause of greenhouse gasses and ozone depletion. So next time you get ready to throw something away, ask yourself if you could possibly use the item in another way or donate it.

Nanosolar Takes Solar Power to the Next Level

A relatively new startup called Nanosolar has announced that they have $4 billion in contracts to sell their solar panels that produce $1 per watt. That is a low enough price point to take on those awful fossil fuels.

The key to their success is how they propose electric utilities make use of their technology. You can read all about it in Wired.

Two big announcements marked its coming out party: The company has $4 billion in contracts and can make money selling its products for $1 per watt of a panel’s capacity. That’s cheap enough to compete with fossil fuels in markets across the world.

Specifically, the company’s management thinks it can help utilities avoid the difficulties of getting big coal and nuclear power plants built by offering the option to build small solar farms they can set up close to cities.

“Cost-efficient solar panels such as ours can be deployed in 2- to 20-megawatt municipal solar power plants that feed peak power directly into the local distribution without requiring the expense of transmission and with a plant deployment time as short as six months,” said Nanosolar CEO Martin Roscheisen in an e-mail to Wired.com. “Coal or nuclear can’t do that, can’t do it as cost efficient and can’t do it as rapidly deployable.”

Thin-film solar has been a major focus of U.S. alternative energy research and development efforts since the early 1980s because it was seen as a true “breakthrough” solar technology. Silicon cells are easy to manufacture, dependable and efficient, but some researchers viewed them as inherently limited. As they are currently produced, they require a lot more silicon than thin-film solar cells. They might reach efficiency levels of over 40 percent, but they’d never compete with fossil fuel energy sources, even with carbon taxes.

Thin-film solar was different. On the one hand, it was definitely harder to make efficient cells. However, it allowed researchers to dream of printing semiconducting chemicals onto a metal sheet and having it convert photons into electricity. Thin-film cells seemed like they’d be perfect for the applications researchers imagined like “solar shingles” for building-integrated solar installations.

Safe Sex is Good for the Planet

Researchers at the London School of Economics have released an argument that posits that family planning is one of the best things we can do to fight climate change.

Every Ă‚ÂŁ4 spent on family planning over the next four decades would reduce global CO2 emissions by more than a ton, whereas a minimum of Ă‚ÂŁ19 would have to be spent on low-carbon technologies to achieve the same result, the research says.
The report, Fewer Emitter, Lower Emissions, Less Cost, concludes that family planning should be seen as one of the primary methods of emissions reduction. The UN estimates that 40 per cent of all pregnancies worldwide are unintended.
If these basic family planning needs were met, 34 gigatons (billion tonnes) of CO2 would be saved – equivalent to nearly 6 times the annual emissions of the US and almost 60 times the UK’s annual total.
