Mentioned at Green Diary, these earth-friendly flip-flops are made from recycled newspapers with the addition of re-purposed coconut shells, palm tree roots and recycled rubber.
The newspaper supports the feet and the straps, base and sole are made of the sustainable re-purposed materials.
The re-purposed materials give durability, water resistance and a good grip, 1 kg of newspaper is recycled for each pair, and for an even happier result a project is afoot (Mrs Green did not initially intend that pun) to create employment opportunities by making Paperflops for disabled and underprivileged people in Yogjakarta, Indonesia.
Volunteers built a school in San Pablo in the Philippines out of thousands of recycled plastic bottles.
The bottles were filled with liquefied adobe and steel bars and then cemented into place. The result is claimed to be three times stronger than concrete.

Pieter 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.
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 crystal-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.
The U.S. Department of Energy’s Los Alamos National Laboratory and Brookhaven National Laboratory have developed a transparent film that could potentially generate power by transforming windows into solar panels.
Imagine every window of your house generating power. Now – imagine every window of every office building and skyscraper doing the same.
The Green Tech Gazette has an article about it here, and the Los Alamos National Laboratory website has more information here.
