  • 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. However, environmentally-friendly announcements over the past few years have challenged this perception.

  • 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…

  • 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…

  • Aquaduct Bicycle

    Note: The following image links to a promotional video from Aquaduct In the most recent Innovate or Die contest sponsored by Google and Specialized, the grand prize winner was the Aquaduct, a pedal-powered concept vehicle that transports, filters, and stores water for the developing world. According to the website, As the rider pedals, a pump…

  • LifeStraw®

    According to the World Health Organization, 3.575 million people die each year from water-related disease, and 84% of water-related deaths are in children ages 0 – 14. Access to safe and clean water is an option many people in developing countries don’t have. I think the picture above says all that is needed about the LifeStraw®,…

  • Water Pyramid

    A Dutch company has created the Water Pyramid to help create safe, clean drinking water in tropical and developing countries. While traditional reverse osmosis systems are expensive to build and use a considerable amount of energy, the Water Pyramid uses the sun as its primary energy source and has low operational and maintenance costs. The…

  • Water Footprinting

    Last week, the Wall Street Journal published an article about how companies are starting to calculate their “water footprint” as well as their carbon footprint to institute more water friendly policies. Commercial companies have discovered that it takes “20 gallons of water to make a pint of beer, as much as 132 gallons of water to make a…
