This post is CleanTechnica’s contribution to Important Media’s celebration of World Water Week.
While most of the technologies we write on here on CleanTechnica –
solar power, wind power, energy efficiency, and clean transportation
technologies – are focused on addressing our climate and energy crises,
another critical crisis facing the world today is the water crisis.
Did you know that 80% of the world’s people face water insecurity and lack of clean water kills more people each year than war?
The clean technologies above do
actually go a long way in helping us address the water crisis, but
there are others out there focused solely on that goal. Here are 10
water-saving and water-cleaning technologies we’ve written about so far:
- Wind Power Turbines (yes, general old wind turbines – they are the least water-needy electricity generator out there)
- Solar PV Panels (not far behind wind turbines, and far ahead of almost every other power option)
- Fuel cells out of the University of Colorado that desalinate water, treat water, AND produce electricity… using microbes.
- Minced banana peals.. seriously. They can clean polluted water, removing such metals as lead and copper. (OK, not technology, per say, but worthy of inclusion here.)
- The Groasis Waterboxx, a device create by Dutch inventor and lily grower Pieter Hoff that uses biomimicry to create dew.
- Wastewater Compliance Systems’ igloo-shaped water treatment device, expected to save small communities millions of dollars and allow them to provide clean water to more people.
- Silver nanowires on cotton layered with carbon nanotubes developed by Stanford scientists that kill up to 98% of E. coli bacteria in water without the use of chlorine.
- Glass that swells and soaks up pollutants, but not water, like a sponge, developed by scientists at the College of Wooster.
- Portable solar desalination machine created by MIT engineers – good for disaster-stricken areas or people living in remote locations.
- And… smart fire hydrants that conserve a ton of water.
