China built the ‘World’s biggest air purifier’ – and it’s actually working

from Inhabitat

What has been called the world’s largest air purifier by its operators is now up and running in the Chinese city of Xian in Shaanxi province. The 100-meter (328 feet) tall tower has already improved the local air quality, lead scientist Cao Junji told the South China Morning Post, adding that it could prove to be a valuable tool in the country’s fight against urban air pollution. “The tower has no peer in terms of size … the results are quite encouraging,” he said. Greenhouses covering the size of half a soccer field surround the base of the tower, into which polluted air is pulled. The smog is heated in the greenhouse by solar energy, then rises through the tower, passing through several layers of cleaning filters.



Cao stresses that the results are only initial while further details will be released in the spring. A comprehensive scientific assessment of the tower’s effectiveness is also forthcoming. Nonetheless, what is known is promising. While there have been other similar smog-removing towers, many of which were powered by coal-fueled electricity, the Xian tower is unique in its very limited electricity needs. “It barely requires any power input throughout daylight hours. The idea has worked very well in the test run,” said Cao. While locals have marveled at the tower’s size, it is in fact a miniature version of smog-removing towers that Cao and his team hope to install throughout China’s dense, massive cities. The full-size version could reach as high as 500 meters (1,640 feet) while the surrounding greenhouses could cover nearly 30 square kilometers (11.6 square miles).

Tiny Homes for the Homeless an Occupy Madison Project

from Revolution News:

Madison Wisconsin: In a city with a homeless population that has risen by 7 percent over the last four years to about 3,370, Occupy Madison organizers decided to tell their local leaders to “put up or shut up” and developed a non profit organization Occupy Madison Inc. In June 2013 OM Build was born and Tiny Homes was decided on as a solution.

To achieve their goals of a Tiny Village complete with 9 tiny homes, permanent comprehensive day resource center, safer places to sleep at night, as well as access to restrooms, showers, laundry, community gardening space, and other basic needs for people experiencing homelessness, OM Build realized that they would need to work from within the system. The hard and relentless work paid off. Scheduled for November 15th 2014 is a Ribbon Cutting Event for The first Tiny Village for the Homeless in Madison.

Local organizers also state “Our approach to working within the system came only after we realized that without dotting every “i”, and crossing every “t”, the city and the county would never let us operate– they used every opportunity to enforce ordinances, regulations, and seemingly arbitrary whims against us. This paralleled precisely the persecution of everyday, unaffiliated, homeless individuals. When you are homeless, “the system” is rife with obstacles designed to prevent creative innovation or adaptation– we at Occupy Madison experienced the same headaches.” organizers also stated “In many ways, we have had much more success since we changed our approach. This was due not only to how we communicated with city and county offices (we never shirked from being open or transparent), but how we are perceived by Madison’s genteel liberal population. It’s stunning how a flowerbed on a windowsill can be so much better for PR than the window itself, or the house it’s attached to.”

At least six other cities nationwide are adopting Tiny Homes… others are installing Homeless Spikes. One OM Build organizer in Madison stated that Homeless pikes are “disgusting” and a “weak attempt to make even society’s most uninviting spaces– doorways, parks, etc– uninhabitable as well” He also states “People don’t choose to sleep in the gutter. Physically preventing people from getting whatever rest they can will not help them in any way, and nor do they help society. It’s tempting to say that for every spike a municipality erects, they should provide a warm, safe, clean, bed. But the truth is that we should be providing those beds anyway.”

Local organizers and volunteers state that “next is occupancy and fundraising. We’ve done a lot of work and spent a lot of money getting our site ready for people to move in. Now is a critical time for us financially– if we can’t raise enough funds to pay for making the site as wonderful as it is, there’s a real risk our whole project could go under.” Donations can be sent to paypay account http://bit.ly/1uSYGew Fundraiser in the past have been matched on a dollar per dollar basis and none of current progress would be possible without a 100% volunteer effort.

Local grass root groups that deserve a special shout out include: Friends of the State Street Family, The Bubbles program, (which provides free laundry services to the homeless), Occupy Madison, OM Build, Homeless Ministry at Bethel Lutheran Church, Madison Street Pulse (a cooperative homeless newspaper based In Madison WI).
