Green Options

A Swedish inventor has unveiled a solar-powered water purifier that could provide billions of the world’s poorest people with access to clean and disease-free drinking water [video].

The device, called the Solvatten, (Swedish for ’sun water’), looks much the same as a standard jerrycan and can be filled with up to ten liters of water, opened out, and left in the sun. A simple indicator shows either a red or green face to let users know when the water is safe to drink (typically after 3-4 hours), thus avoiding the risk of contracting water-borne diseases.

The United States has overtaken Germany to become the largest producer of wind energy in the world, generating enough capacity to eliminate the burning of 91 million barrels of oil per year.

According to the American Wind Energy Association (AWEA), US wind producers enjoyed another record year of growth in 2008—the third in a row. The country now has an installed wind power capacity well in excess of 21,000 megawatts (MW), enough to supply electricity to over 5.5 million American homes.

US Scientists have figured out a way to mass produce the nanomaterial graphene, opening the door to significant advances in the storage of hydrogen, as well as the electricity produced by solar and wind energy.

Graphene, produced by reducing graphite down to a sheet only one atom thick, is one of the strongest materials known to man. It has been shown to have huge potential for hydrogen and renewable energy storage, but up until now has been held back by a lack of supply. Now the team, based at the California NanoSystems Institute (CNSI) at UCLA, have discovered a method of producing graphene sheets in large quantities.

Go take a look at the adhesives you use in your crafting. Go ahead, I’ll wait here.

Back? Ok, good.

What is the one thing that they probably have in common? Does it say somewhere “use in well ventilated area” or some similar warning? Well, that warning often accompanies many of the glue and adhesive products found on the shelf at the crafting supply store and in crafters’ homes. That warning is there because of the chemicals used in the adhesives. Chemicals that, if inhaled in concentrated amounts, can be bad for you, hence the “well ventilated” part.

EcoGlue is a new white craft glue that claims eco-friendly properties. It contains less than 1% of volatile organic compounds or VOCs, has virtually no hazardous air pollutants, contains no animal derivatives and does not carry a “well ventilated” warning on its label. In fact its packaging is made from 100% recycled content and carries a “non-toxic” stamp.

I got the chance to try out this new glue and ran it through some simple and highly unscientific tests to see if it the eco-friendly label still meant quality adhesive or if it was just some watered down glue.

The Fair Trade movement operates under the basic market principle of supply and demand. In order to spread the ideas of economic sustainability and justice to others, we create demand for Fair Trade by spreading the word. But with demand for Fair Trade products repidly increasing (by more than 40% a year) around the world, we need to ensure that Fair Trade products are easily accessible in the marketplace. And just
