Fishing for Pollution
Scientists at the University of Essex have developed robotic fish that can detect pollution. Unlike previous robotic fish, these fish have autonomous navigation capabilities which enable them to swim independently. For recharging and data transmission, the fish are able to return to their charging hub where the data provide real time source and scale of…

Will the Fortune 100 Save Us?
Environmentalists have long criticized our corporate behemoths for environmental violations and unsustainable business practices. Walmart, GE, Coca-Cola were once considered toxic to the environment and not the names that came to mind for a green future.

Water for Profit?
I’ve long been fascinated by the concept of privatization of water. I can think of few topics related to natural resources that are so controversial. I tend to reject the claim, espoused by many including former Water Center speaker Maude Barlow, that water is a basic human right and therefore should never be private. While water…

Water Usage Per Person
Seeing Samantha’s post on water conservation kits reminded me how much water we use in the US compared to others in the world. The above data is from UNDP Human Development Report 2006. For your reference, 1 liter = 0.264172052 US gallons. I hope there are a lot of related posts that come from this…

Free water saving kits from NYC DEP
If you go to the New York City Department of Environmental Protection website, you’ll see that nearly half the items on the homepage are about water. There’s the large scale, like protecting and maintaining the sewer systems and watersheds, and also the smaller scale, such as their rain barrel and residential water conservation programs. As…

Sand Filtration
Via ScienceDaily, Dr. James Amburgey, from the University of North Carolina at Charlotte, has developed an inexpensive and low-tech way to treat water using sand. According to Dr. Amburgey, all that is needed to create safe drinking water is PVC pipe, sand and inexpensive treatment chemicals. Previous technologies have used sand filtration, however, this current…
