The push to extend fracking to arid regions is drawing attention to water-free techniques.
Hydraulic fracturing, or fracking, uses large amounts of water injected into wells under high pressure to help free natural gas and oil from shale deposits (see “Drilling for Shale Gas”). Yet some of the world’s largest sources of shale gas are found in deserts, making the technique seem impractical.

NASA launches Landsat 8 satellite to better study the skies above, water below

NASA’s Landsat program recently turned the big four-oh, and what better way to deal with the mid-life crisis by getting a new satellite as a present? Accordingly, the space agency has just launched Landsat 8 into orbit to give its Earth Science program a new injection of youth. The new vehicle improves the accuracy of existing light and thermal sensors while widening the scope to better reflect modern climate studies — number 8 now tracks aerosols in the atmosphere, high cirrus clouds and the telltale signs of water quality and consumption levels. We won’t get the first USGS-derived results from the new satellite until after a 100-day shakedown period, but we’re sure the deeper understanding of our planet will help the Landsat program forget all about those first few gray hairs.

Curiosity rover drills into Martian rock, looks for more evidence of water

NASA scientists won’t have to wait until InSight’s 2016 drilling mission to see what lies beneath the surface of Mars — Curiosity is already on the case. After developing a taste for Martian soil late last year, the intrepid rover has started exploring the red planet’s bedrock, drilling a 0.63 inch (1.6 cm) wide hole 2.5 inches (6.4 cm) deep into Mars’ surface. Curiosity will spend the next several days analyzing the resulting powder in hopes of finding evidence of a once-wet planet. The shallow hole marks the first drilling operation ever carried out on Mars, and getting there wasn’t easy. “Building a tool to interact forcefully with unpredictable rocks on Mars required an ambitious development and testing program,” explained Louise Jandura, the chief engineer of the rover’s sample system. “To get to the point of making this hole in a rock on Mars we made eight drills and bored more than 1,200 holes in 20 types of rock on Earth.” The Rover tested its drill by creating a shallower hole earlier this month, though samples will only be used from the second, deeper cavity. Check out the source link for more images of the operation, including an animated GIF of the drill in action.

Robot fish glides out of Michigan State University, tells you if the water is clean

Autonomous fish might make great leaders, but it turns out that robot flippers are a huge drain on battery life. Not a problem for Xiaobo Tan — he and a group of Michigan State University scientists have built a robotic fish that glides through the water. Tan says the machine, dubbed Grace (Gliding Robot ACE), swims too , but the constant flipper movement can kill the battery in just a few hours. “This is why we integrated both locomotion modes,” he explained. “Such integration allows the robot to adapt to different environments, from shallow streams to deep lakes.” Grace is designed to scour lakes and rivers for data to help cleaning efforts, and older prototypes have successfully found traces of crude oil in once spoiled riverbeds. The redesigned robot looks more like an airplane than a fish, but it’s hard to argue with results — the team says Grace should be able to glide through the water almost indefinitely. Check out the team’s press release after the break.

Critical infrastructure is at risk of a cyberattack because of systems that haven’t kept pace with Internet threats.
U.S. defense secretary Leon Panetta warned this week that successful attacks have been made on computer control systems of American electricity and water plants and transportation systems. Panetta didn’t give details about those incidents, but he said they showed that foreign nations or extremist groups could use such tactics to derail trains or shut down power grids. Computer-security experts say those claims are plausible—even if the scenario is not necessarily likely to happen—because of the outdated technology used to operate critical infrastructure.

If Google-lovin’ Koreans were a little jealous after seeing Eric Schmidt turn up in Japan with a Nexus 7-shaped gift under his arm, they needn’t be. It looks like the Executive Chairman brought another one along with him on his Asian travels. It wasn’t just the hardware that came along for the ride either, with The Next Web reporting that the firm also made movies available in the countries edition of Google Play. The Korean asking price will be a reported KRW 299,000 (about $ 267) for the 16GB edition, a smidgen less than its neighbor’s (¥19,800 / $ 312). We suspect, though, not quite enough to warrant a ferry ride.

Green House’s lantern runs on salt and water, powers your gadgets via USB

on September 7, 2012
No comments
Japanese company Green House Co Ltd has quite an eclectic product portfolio, what with its women-only camcorder and peripherals like a PCI Express interface card with USB 3.0 support. Its latest device falls under another category entirely: the rivetingly named GH-LED10WBW is an LED lantern that runs on just water and salt; no batteries required. The light source provides eight hours of electricity per dose of saline water, and the lantern comes with a dedicated water bag for mixing the solution. The salt / water combo acts as an electrolyte with the magnesium (negative electrode) and carbon (positive electrode) rods inside the lantern. Users can get about 120 hours of power with the Mg rod before they’ll need to buy a replacement (the rod is sold separately to begin with). More than just supplying a battery-free source of light, though, the lantern can function as a charger, thanks to a USB port built into the casing. Pricing has yet to be announced, but the GH-LED10WBW will be available by mid-September.

Micromotors Race About By Turning Water Into Hydrogen Gas
Posted by Gsurface
on August 28, 2012
No comments
MTorrice writes “Microscopic particles of aluminum and gallium rocket around using water as their fuel. The particles, which are 20 micrometers in diameter, are asymmetric: A chemical reaction on the back side of the particle forms hydrogen gas bubbles that propel the motor forward. Over the past several years, bioengineers have built micro- and nanosized rockets that zip through liquids, fueled by chemical reactions between the materials that make up the rockets and their environments. The engineers hope someday these tiny motors could help deliver cargo, such as drugs, in people. Unfortunately, many of these motors require toxic hydrogen peroxide as fuel source, limiting their use in the body. To overcome that constraint, the new micromotors harness a well-known reaction between aluminum and water to produce hydrogen gas.”

The power of the internet lies in its near-infinite mutability. It’s an edifice of information being added to and sculpted by as many hands as there are eyes viewing it. Truly democratic and increasingly accessible, it will soon be the vector for most communication that takes place on our world.
But its mutability is also a weakness, as so many great strengths are. The weakness arises from a lack of permanence: it is impossible to make an indelible mark.
Lack of permanence! you say. Why, I can request 500 pages of data on file at Facebook, and the NSA is building a profile on me that includes every cookie I’ve ever been issued. True, but the data itself is impermanent. Vulnerable in a dozen ways to being rewritten, manipulated, retouched, softened, or otherwise reduced from a record to a falsification.
The data we create today is not etched in stone but “writ in water.” The benefits of this we have seen, and monumental they are, but soon we will know its danger, too.

Fran Bagenela, of the University of Colorado, told a group of scientists at the recent meeting of the American Astronomical Society in Anchorage, Alaska, that the Galileo probe fell at the boundary between one of the brown atmospheric zones and white belts that form a striped pattern across the planet’s face. This gap region could have been unusually dry, she added. Now it’s up to Juno to investigate when it enters orbit around Jupiter in 2016.”

New submitter horselight writes “Recent data obtained from Mars indicates the environment is not as hostile to life as once thought. ‘An examination of data gathered by NASA’s Mars Exploration Rover Opportunity reveals deposits that, on Earth, are only created by water moving through the rock.’ The study’s lead author, Steve Squyres, said, ‘From landing until just before reaching the Endeavour rim, Opportunity was driving over sandstone made of sulfate grains that had been deposited by water and later blown around by the wind. These gypsum veins tell us about water that flowed through the rocks at this exact spot. It’s the strongest evidence for water that we’ve ever seen with Opportunity.’ Gypsum veins and other features indicating water movement on the surface of Mars have been observed to be much more common than previously thought.”

mdsolar passes along this quote from an Associated Press report:
“One of Japan’s crippled nuclear reactors still has fatally high radiation levels and hardly any water to cool it, according to an internal examination Tuesday that renews doubts about the plant’s stability. A tool equipped with a tiny video camera, a thermometer, a dosimeter and a water gauge was used to assess damage inside the No. 2 reactor’s containment chamber for the second time since the tsunami swept into the Fukushima Dai-ichi plant a year ago. The probe done in January failed to find the water surface and provided only images showing steam, unidentified parts and rusty metal surfaces scarred by exposure to radiation, heat and humidity. The data collected from the probes showed the damage from the disaster was so severe, the plant operator will have to develop special equipment and technology to tolerate the harsh environment and decommission the plant, a process expected to last decades.”
