Bar stools and plastic bags

Artists for Humanity (AFH), with a mission “to bridge economic, racial and social divisions stool made from plasic bagsby providing underserved youth with the keys to self-sufficiency through paid employment in the arts”, has designed bar stools using recycled plastic carrier bags.

GreenMuze tells us that each stool is made from 200 plastic bags that are melted into plastic “lumber” and created by inner city youth in the USA. Design by Jamison Sellers, from AFM.

Building with plasic bottles

The bottles were filled with liquefied adobe and steel bars and then cemented into place. interior plastic bottle schoolThe result is claimed to be three times stronger than concrete.

A bucket with a cover grows trees in arid places

water pot for growing treesPieter Hoff won Popular Science magazine’s award for Popular Science magazine’s award for the 2010 Best of What’s New Innovation of the Year (the picture is theirs).

The cover on the bucket has 2 holes in it so it can catch water from rain or condensation once a sapling or seeds are planted in it. There is a wick that drips enough water onto the plant to allow it to survive in this micro-climate while it grows tap-roots deep enough to find moisture. It will also last for about 10 years so can be used at least 10 times to establish a new tree. They’ve been extensively tested over the past few years.

The Guardian has an interview with the inventor here and here is a lovely gallery from the official Groasis Webite. Details of various projects are here. Mrs Green will be keeping an eye on this.

Wetland-filtered swimming pools

The Green Power House  has been experimenting for over a year with a “wetland” filtering system for a swimming pool. I went to investigate it yesterday.  Remarkable. The pool water is crywetland-pool-1-150x150stal-clear. It smells like a pristine  mountain pool.

Mrs Green understands the process as follows: The water overflows into a section of the pool (planted with reeds and similar plants),  from where it’s pumped into a swampy area planted with typical wetland plants. Water from this section seeps into another (also planted) shallow pool, from where it’s pumped back into the pool via a cascading water feature.  One did, after seeing the result, ponder the efficacy of wetlands and how misunderstood is the necessity of preserving them.

One also immediately wanted to dive into this beautiful pool but restrained oneself at the thought of possibly being firmly escorted off the property.
