Today is world water day. We’ve written quite a number of posts on different ways water is connected to cleantech and clean energy. Rather than write a whole new post on one or two aspects of this, I’ve decided to do a compilation piece. The following are articles on CleanTechnica (and a few from our sister site Planetsave) on some of the connections between cleantech and water.
In a long overdue measure, the U.S. Environmental Protection Agency announced last week that it has asked drilling companies for information on the 200-plus chemicals routinely pumped into the ground during a natural gas drilling technique called hydraulic fracturing. Also known as fracking, the practice has touched off a firestorm … [continued]
Chemical treatment is becoming a less desirable way to provide safe drinking water, and water professionals have been searching for a less expensive, more reliable and more sustainable method of killing pathogens. Cavitation Technologies, Inc. has come up with one solution. The company’s new process uses mechanical and electrical systems … [continued]
New York City is fighting to save its drinking water supply from potential contamination by new natural gas drilling operations, and some unlikely heroes may be ambling to the rescue. Dairy cows are being recruited to provide sustainable manure-derived methane biogas to power homes in New York State. Along with … [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]
Nanotechnology seems to be invading all facets of modern life, from the pills you take to the batteries that power your iPod. Pretty soon, carbon nanotubes may even filter your water. Researchers at the Bhabha Atomic Research Center in India are investigating the hollow carbon fibers as a potential water … [continued]
There’s been a lot of focus on renewable energy on Cleantechnia recently but energy is not the only “clean” tech out there. What about recycling wastes? What about recycling… human wastes? What’s the difference between traditional wastewater treatment and sewage purification (also known as ‘indirect potable water reuse”)? Is it … [continued]
