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.

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.

Plastic bricks from trash

New Zealand businessman Peter Lewis designed the Byfusion, a machine that turns raw plastic into compacted bricks.plastic-bricks It takes just 45 seconds to wash, dry and compact the plastic to convert it into a brick.

Each brick contains about 10kg of plastic – anything from drink bottles and packaging boxes to meat wrappings.  They can be used in many innovative ways – see more at  GreenMuze. Even Mrs Green could lift these…

Solar-powered car ventilator

solar-car-ventilatorI’d like to have one of these.  It fits any car window. The past week has been more than hot. Apparently the solar panel, which is 5 inches by 4.5 inches, powers the fan, which exchanges hot air inside the car for the presumably cooler air outside. If you park in the shade and want to use the fan, there’s a plug-in adapter for the car. Cool!

Unfortunately Mrs Green cannot find anywhere to obtain this little lovely. Local Entrepreneur somewhere?

Ultraviolet water purifying bottle

UV water filterThe winner of the UK James Dyson Award, Timothy Whitehead, has designed a water bottle that uses ultraviolet (UV) light to sterilise drinking water anywhere in about 2 minutes.

The bottle has an inner and an outer chamber. The outer chamber is filled with dirty water and the inner chamber plunges through it and filters water particles as small as four microns. The clear water then takes about 90 seconds to sterilise by using a wind-up ultra-violet bulb.  Apparently tests show that it sterilises 99.9% of bacteria and viruses.  Wow!
