NASA Phoenix Lander Finds Water On Mars! [Mars Phoenix Lander]

The landing thrusters aboard the Phoenix Mars Lander apparently did their job and them some. First, they successfully fired and gently deposited the multimillion dollar probe on the surface of the Red Planet. And then, by doing just that, they blew away three to six inches of Martian soil to reveal the shiny, slick face of what could be a large ice patch. Brendan Fraser's frozen caveman body was noticeably absent from this block of ice, but NASA scientists were elated anyway. The discovery reaffirms that the landing was indeed a bull's eye, akin to the Opportunity rover "hole in one" crater touchdown more than four years ago.

"It's the consensus of all of us that we have found ice," said Peter Smith of the University of Arizona, Tucson, which is leading the Phoenix project with help from NASA's Jet Propulsion Lab. "It's shiny and smooth - it's absolutely astounding!" he said. Exclamation points aside, Smith did concede, as scientists are wont to do, that the gleaming slab could be "something else," but the leading interpretation is that future tests will confirm it is ice.

The patch, which was discovered by Phoenix's camera during a routine inspection of its legs, joins several existing targets of digging opportunity. One is called Humpty Dumpty, and the second is the King of Hearts. The ice patch? Thy name is "Holy Cow!" said Smith. All three sites will presumably be where the lander's robotic scoop arm will dig to begin a set of experiments that could prove or disprove the presence of organic, life building compounds on Mars.

MIT Nanomesh Paper Towel is the Last Quicker Picker Upper You'll Ever Need [Nano Towels]

Sorry, Brawny man. Your paper towels were always handy in a pinch for the occasional Coke-on-keyboard spill, but they fall apart when held up against this incredible nanomesh towel from the folks at MIT. Designed with the environmentally unfriendly act of oil spills in mind, this recyclable towel's potassium manganese oxide fibers absorb up to 20 times their weight in oil (which can then be recovered, for future oil spills).

Even more amazing is the fact that this mish-mash of nanowires has the look and feel of paper, but sucks up only oil, leaving every ounce of water behind. Based on that, you know what comes next, right? Water filtration, said Jing Kong, an assistant professor in the Department of Electrical Engineering and Computer Science.And unlike most nanotechnology, the mesh is inexpensive to produce, since the nanowires can be fabricated in larger quantities than other nanomaterials. Great. Let's get huge sheets of this stuff manufactured and distributed to every oil rig, developing nation and tanker like, yesterday. [MIT News]

projectiondesign to launch F10 AS3D active 3D stereoscopic projector

Source: http://feeds.engadget.com/~r/weblogsinc/engadget/~3/301873980/

Filed under: , ,


Look out, naysayers -- projectiondesign is giving this whole "3D revolution" thing some serious street cred with the F10 AS3D. Slated to debut at InfoComm 2008 in Las Vegas, the unit marks the company's first active 3D stereoscopic projector. Notably, this isn't the firm's first foray into the third-dimension, as eight of its F20 sx+ PJs are currently being used in a 3D visualization system at Munich University. Moving on, we'll also find its brand new three-chip DLP F80, which features a WUXGA (1,920 x 1,200) resolution, ACOP (Advanced Color Optical Processing) technology and a stratospheric price tag (we're guessing on that last one). We'll be holding out for pricing / release information, but we don't suspect it'll be too long before those critical points get divulged.

Napa Valley winery flips on Flotovoltaic solar array

Filed under:


Chalk another one up for Sharp. The company has landed yet another partner willing to utilize its solar panels in order to make news, wow onlookers and give Mother Earth a modicum of a break. Napa Valley winery Far Niente has flipped on its self-coined Floatovoltaic installation, which was developed by Thompson Technology Industries and installed by SPG Solar. Nearly 2,300 Sharp solar panels were secured for the job, and we're told that the array generates 400 kWs at peak output, which "significantly offsets the winery's annual power usage and provides a net-zero energy bill." Don't expect that coveted bottle of Cabernet Sauvignon to be any cheaper as a result, though.

ElectraTherm's Green Machine converts waste heat into electricity

Source: http://feeds.engadget.com/~r/weblogsinc/engadget/~3/302460581/

Filed under:


Converting residual industrial heat into something usable (read: electricity) has proven to be more than a novel concept on more than one occasion, and ElectraTherm's giving the process one more vote of confidence by installing its Green Machine at Southern Methodist University. Just this past week, the firm flipped on its first commercial waste heat generator at the Dallas-based institution, with hopes to generate "fuel-free, emissions-free electricity at three to four cents per kW/hr during payback period and under a penny/kW hour thereafter." The 50kW rig has so far exceeded expectations, and the firm is now forecasting that its units will have a "subsidy-free payback period of three years or less." Of course, we aren't told exactly how many zeros reside on the left of the decimal or anything, but folks in the area can get a tour of the installation later this month.
