Solar water disinfection is an idea so simple, it hurts. Now a Georgia Tech scientist may be on to a new high-tech twist that could make this no-cost, zero emission ultraviolet (UV) water disinfection method even more quick and effective. [social_buttons] Solar disinfection is a proven method of killing germs … [continued]
In an elegant piece of sustainable engineering, the company Renew Blue, Inc. will use wave power to run a desalination plant in Freeport, Texas, then bottle the results in corn-based biodegradable plastic for sale under the Renew Blue brand. The wave power system, called SEADOG, will employ a buoy-and-piston mechanism … [continued]
A Woman’s Work… The Governor’s Global Climate Summit ended with Oxfam America’s inaugural Sisters on the Planet Climate Leader Awards. Thanks to Karen Solomon at Opportunity Green, I was able to attend. The event showcased the work that women all over the world are doing to adapt to climate change. … [continued]
In its search for more fuel efficient ways to provide drinking water for long sea voyages and remote bases, the U.S. Navy has developed a second-generation desalination unit that use 65% less energy than conventional technology. It’s only in the prototype stage but the Navy is already looking beyond seagoing … [continued]
MIT professor Daniel Nocera formed a company earlier this year to commercialize a new technology that can “split water” and store solar energy. The company’s key objective now: achieve a solar energy breakthrough.
Waste uranium can apparently be recovered very cheaply from the polluted runoff from uranium mining using E. Coli and a phosphate storage molecule found in seeds, British researchers have found. They used the common bacteria with a chemical parallel of what is already found in agricultural waste: inositol phosphate. Inositol … [continued]
[social_buttons] A new water dispensing technology created by UK designer Oliver Craig could change the way that European shoppers and commuters drink water, and it’s a technology that could help eliminate water bottle waste that’s cluttering international landfills greatly due to increased convenience.
A breakthrough discovery from Sandia National Laboratories could help keep a lid on the rising cost of chemical water treatment and make clean drinking water more affordable in “water challenged” areas of the world. Working with researchers at the University of California, the Sandia team substituted one atom in aluminum … [continued]
High-tech membranes are catching on as a lower cost, non-chemical and more sustainable water treatment process, but there’s a catch: they can quickly foul with dirt and other particles. Enter NanoBrane, a nanotechnology company with a patent-pending breakthrough in membrane properties that prevents fouling. That makes the treatment process run … [continued]
The biggest commodities boom of the 20th century was a bust for water and wastewater utilities, which found themselves locked in a battle with manufacturers for vital water treatment chemicals over the past five years. Competition for more chemicals to grow biofuel crops didn’t help, either. Prices for some chemicals … [continued]
