Daiwon Choi won for his entry showing the creation of nanotubes. At EMSL, scientists study polypyrrole conductive polymer-coated carbon nanotubes grown on a carbon fiber. These nanotubes could aid in obtaining a high-surface-area electrode for efficient water purification.

Energy and environmentalism flow together to save the Grand Canyon: This frothy flume is what 300,000 gallons of water per second looks like. A 60-hour surge of almost 75 billion gallons, it’s part of an effort to revitalize the ecosystem of the Colorado River and the Grand Canyon. Teams from the U.S. Geological Survey, the Grand Canyon Trust and 25 other agencies have been working together since 1995 to develop a plan that will mimic natural flooding to redistribute sediment that would normally wash downriver. Moving the sediment from the central riverbed to the riverside rebuilds the sandbars downstream that serve as natural habitats and backwater nursery grounds for endangered fish species such as the humpback chub, as well as camping grounds for recreational use.

This most recent discharge was the third of its kind. The first, in 1996, washed what little sediment there was downstream past the Grand Canyon and into Lake Mead. The second, in 2004, redistributed too little sand. Definitive results on the success of this last experiment should be available within the year and will serve as a guidepost for the next flow, which is as yet unscheduled.

Probably one of my favorite inventions, a machine that can suck out the moisture in the air, filter it and sterilize it, serving it up either hot or cold. Producing up to 7 gallons of pure water using half the the electricity of your microwave. Whats better is its available to the public for a affordable price $1200. Whether your trying to get a little extra water at your cabin or trying to prevent world hunger this is the machine for you. Water wells can cost anywhere between $6000-10000, and theres no guarantee you will hit water, especially where its most needed the desert. It is my believe that if this machine was sold on the mass market like walmart, and  costco the price would dramatically come down to $600 and efficiently go up to 10 or more gallons of water per day.

Eole Water claims to have successfully modified the traditional wind turbine design to create the WMS1000, an appliance that can manufacture drinking water from humid air.

The company aims to start rolling out the giant products for sale later in 2012, initially focusing on remote communities in arid countries where water resources are scarce.

“This technology could enable rural areas to become self-sufficient in terms of water supply,” says Thibault Janin, director of marketing at Eole Water.

“As the design and capabilities develop, the next step will be to create turbines that can provide water for small cities or areas with denser populations,” he adds.

Eole Water is currently displaying a working prototype of the 24 meter tall WMS1000 in the desert near Abu Dhabi that has been able to produce 62 liters of water an hour, says Janin.

Once-wet Mars has long been the primary focus of the search for life on other planets. But Saturn’s moon Enceladus could be an even more promising place to start the search for extraterrestrials. Startling new images from NASA’s Cassini spacecraft indicate that Enceladus may contain pockets of liquid water below its icy crust.

These pockets, described in an article published today in the journal Science, may be ideal habitats for life-forms similar to those found in hydrothermal vents beneath the Earth’s oceans.

“This is extraordinary,” said Carolyn Porco, a Cassini team leader at the Space Science Institute in Boulder, Colorado and primary author of the new study.

“I think our results are significant enough to redirect the planetary exploration program, placing Enceladus as the primary target of astrobiological interest in our solar system.”
