NASA's stunning Perpetual Ocean animation visualizes ocean currents (Image: NASA/Goddard S...

NASA’s Goddard Space Flight Center is an unlikely entrant in the SIGGRAPH Computer Animation Festival. Its “Perpetual World” animation may have failed to appeal to the judging committee of the 2011 edition of the competition, but it sure succeeded in catching our eye. The jaw-dropping animation visualizes the flow of surface ocean currents around the world. The raw data regarding the currents from June 2005 through to December 2007 has been turned into a work of art reminiscent of van Gogh.  Read More

The giant plug inflates to roughly 32 feet (9.7 m) long and with a diameter of 16 feet (4....

What’s the best way to plug a giant hole? Why with a giant plug, of course. That’s the thinking of the Department of Homeland Security’s (DHS) Science and Technology Directorate (S&T), which has created just such a giant plug to contain flooding or dangerous gases in mass transit tunnels. Measuring roughly 32 feet (9.7 m) long and with a diameter of 16 feet (4.9 m), the giant plug is an enormous inflatable cylinder that can be filled with air or water in minutes to quickly seal off a section of tunnel in the event of an accident, natural disaster or terrorist attack.  Read More

Tiny fibers in the new aerogel serve the same purpose as tiny hairs on the water strider's...

Aerogels are among the lightest solid materials in existence, and are created by replacing the liquid component of a gel with a gas – this results in their extremely low density, and has earned them the nickname of “frozen smoke.” Now, scientists have created a new type of aerogel that is inspired by the feet of the water strider. The material is reportedly so buoyant, that a boat made from one pound (454 grams) of it could carry about 1,000 pounds (454 kg) of cargo.  Read More

The Source UTA drops 1.5 L of water into your hydration pack in under a minute

Filling up your hydration pack just got a little easier ... not that it necessarily needed to. The Source Universal Tap Adapter is a simple attachment that lets you refill your hydration reservoir through the drink tube rather than the opening in back. You can fill up on the go without ever taking your pack off.  Read More

The Vapur Element comes in three color options: Water, Fire and Wind

The intriguingly named Anti Bottle just got updated. The new Element is purpose built large for the thirstiest customers and features a couple of updates from the original Anti Bottle models. It is the largest Anti Bottle yet, coming in 0.7 liter (24 oz) and one liter (34 oz) sizes, with a wide mouth "SuperCap" to deliver that extra fluid to your body more quickly. It also gets a stronger attachment clip designed to better hold on to your backpack during intense workouts.  Read More

The JetFlow manifold

The JetFlow hydration widget is a little bit old school and a little bit new school. It pulls the dirty, moldy, bacteria-ridden hydration bladder out of your backpack and replaces it with a good old-fashioned water bottle you can toss in the recycling bin or dishwasher - but with much of the function of a hydration bladder intact.  Read More

The LCD screen lets you know when purification is done

When you're dealing with the impurities of your local city water supply, a Brita filter should be enough to give you clean-tasting water. But when you're dealing with the impurities lingering in a raw, untreated stream in the woods, you'll need something stronger. This solution from Camelbak - the All Clear bottle - gives you an integrated UV purifier designed to kill all those nasty microorganisms that just live to wring your intestines out.  Read More

Mars Express has used its MARSIS radar to give strong evidence for a former ocean of Mars ...

The European Space Agency (ESA) has provided more evidence that suggests the surface of Mars was once home to an ocean. Featuring ground-penetrating radar capabilities, the MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding) radar aboard the ESA’s Mars Express spacecraft has detected sediments like that seen on an ocean floor.  Read More

If HyperSolar has its way, solar hydrogen farms like that imagined here may not be so very...

HyperSolar claims it is developing a zero carbon method of producing hydrogen gas from wastewater by harnessing solar energy. Hydrogen gas is a clean source of fuel in that, theoretically at least, the only waste product is water. But hydrogen gas does not occur naturally on Earth, and requires energy to create. Typically that energy comes from traditional, carbon dioxide-emitting sources, rendering hydrogen fuel rather less environmentally friendly than it has the potential to be. HyperSolar's work may mean truly clean, renewable hydrogen fuel could be a commercial reality sooner than we might have imagined.  Read More

FLEXR Sports Bottle uses a liner to keep clean

Water is essential to bring along - and drink - during long workouts. Yet cleaning water bottles between uses sometimes doesn't happen. It's hard to get in those long, tall bottles and feel you've gotten all the germs out. The FLEXR Sports Bottle is a new bottle that uses a biodegradable, collapsible liner to ensure the bottle is clean and ready for use.  Read More
