The Story of Electronics employs the Story of Stuff style to explore the high-tech revolution’s collateral damage—25 million tons of e-waste and counting, poisoned workers and a public left holding the bill. Host Annie Leonard takes viewers from the mines and factories where our gadgets begin to the horrific backyard recycling shops in China where many end up. The film concludes with a call for a green “race to the top” where designers compete to make long-lasting, toxic-free products that are fully and easily recyclable
…conventional desalination and reuse technologies use substantial energy. “forward osmosis,” exploits the natural diffusion of water through a semi-permeable membrane. Their process “draws” pure water from its contaminants to a solution of concentrated salts, which can easily be removed with low heat treatment — effectively desalinating or removing contaminants from water with little energy input.
The concentrated salt solution is probably a mixture of ammonia and/or carbon dioxide dissolved in water. The ammonia and CO
are later easily boiled off and reused. The energy required for this quite less even low-cost solar heaters may be sufficient.
Local communities can probably leverage ideas like these to implement open-source design democratized green urban housing. BTW, how can you make a paper house fireproof? I understand that by using resin / coatings you make it waterproof but how it be made fireproof like bricks and not just fire-resistant?
Your thoughts / comments are welcome. Here is the link to the recycled paper house.
