It's pretty easy to cool down an overheating desktop computer with an extra fan, but what do you do if there's no air? That's the hurdle NASA's engineers are hoping to clear with a new prototype pump that the agency unveiled last week. The pinkie-sized instrument relies upon a technology known as electrohydrodynamic (EHD)-based thermal control, which uses electric fields to inject coolant through small vents on a thermal cold plate, before moving the extra heat to a radiator and spreading it far away from any temperature-sensitive areas. With no moving parts, the lightweight cooler uses only about half a watt of power and can be sized to work with small electric components or lab-on-a-chip devices. The challenge is to make sure that the pump can survive the vibrations of a rocket launch, though NASA will put it to the test during a rocket mission on June 9 and in 2013, when an EHD thermal cold plate will be placed on the  International Space Station . 

Each week our friends at  Inhabitat  recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green.  Green transportation took off for the stars this week as Inhabitat reported that the European Space Agency has approved of a new hydrogen-powered  "Skylon" space plane , and we spotted a hot  Star Wars-inspired electric chopper  that wouldn't look out of place on the Death Star. We also learned that NASA plans to rejoin the space race with a new  MPCV craft  fit for deep space flights, while here on Earth we saw GE harness the power of the sun to  charge Volt EVs  before they hit dealerships. Speaking of solar power, Japan unveiled plans to construct  10 new solar power plants  in the wake of the Fukushima Nuclear Crisis, while  Switzerland announced  that it will completely phase out the use of nuclear power. We also showcased a stunning chandelier made from  500 fl...

There's been a lot of talk of things coming to an end at NASA lately, but there are also some new beginnings, and the space agency has now officially filled in one big gap. It's announced that the so-called Multi-Purpose Crew Vehicle (or MPCV) will be its go-to space exploration vehicle for missions beyond Low Earth Orbit -- presumably, the individual spacecraft will get names more up to the level of boldly-named vehicles like Endeavor and Atlantis. If it looks a little familiar, that's because the MPCV will be based on the Orion spacecraft that was developed under the now-canceled Constellation program and, like it, it will be built by Lockheed Martin. Once its put into service, the spacecraft will be capable of carrying four astronauts on missions up to 21 days, and it could even be used as a backup for cargo and crew delivery to the ISS -- to actually get into space, it would blast off atop a heavy lift rocket, and then splash down Apollo-style in ...

Microsoft's WorldWide Telescope -- a collaboration with NASA that explores high-resolution photos and 3D renders of the cosmos -- was already pretty cool, but Redmond upped the ante to incredible with the addition of a Kinect depth camera at MIX 11. Using a piece of software created with the company's upcoming Kinect SDK for Windows, Microsoft gave us a virtual tour of Earth and the surrounding stars, guided by a deep-voiced narrator holding the whole world in his hands. Of course, you'd already know that if you watched the video above, so what are you waiting for? Oh, and we've got more MIX video on the way, so stay tuned. Myriam Joire contributed to this report.

Sending a rover to a distant planet is no small feat, so we might as well make the landing even more spectacular, right? That's exactly what NASA has in mind for its  Curiosity  Mars rover, albeit for more practical reasons. Launching in late 2011 and expected to land on Mars in August 2012, this mobile laboratory will see a unique descent after entering the Martian atmosphere: there'll be the usual separation from the heatshield and backshell, but at about 380 seconds into the entry, the rover will be gently lowered down by wire from a "sky crane," as opposed to taking a leap of faith. Once the landing is complete, the hovering sky crane will then detach from the rover and fly off for a dramatic disposal -- let's just hope it won't hit the now-dormant  Spirit . See for yourself in the video above. Space NASA

Yours truly knows exactly how determined one has to be to achieve the honor of Eagle Scout, but it's getting a heck of a lot easier for the more modern offspring of this world. This month last year, we saw the Video Games belt loop sashay into the Cub Scout ranks and make all of the others seem inadequate, and now, there's yet another award that'll likely have your nerd-of-a-child clamoring to suit up in blue or brown. The Robotics merit badge was just made official within the Boy Scouts of America, falling nicely into a sect that promotes science, technology, engineering and math. Officials are purportedly expecting some 10,000 or so of the nation's 2.7 million Scouts to earn this badge within the next dozen months, with those who choose to do so required to "design and build a robot while learning about robot movement, sensors and programming." Thankfully for aspiring Ben Heckendorns, we're told that "even some video game controllers ca...

Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. As the nuclear crisis at Japan's Fukushima power plant continues to devastate the region and one reactor sprung a leak releasing tons of radioactive water, this week Inhabitat reported that green algae could play a critical role in cleaning up the spill. We also brought you Japan's latest radiation-detecting robot , and we took a look at how fallout from the controversial crisis is affecting energy policy around the world -- China is cutting plans for future reactors in favor of solar fields while Germany may trade 17 nuclear plants for wind farms. In other news, green transportation went from the soaring skies to the deep blue sea this week as we looked at NASA's self-healing "magic skin" that will protect planes from lighting, and Sir Richard Branson unveiled a streamlined eco sub that will explore the ...

Piezoelectric nanowires are the stuff that make power-generating pants a possibility, and that prodigious potential has drawn the attention of NASA. You see, self-powered spacesuits are awfully attractive to our nation's space agency, and a few of its finest student researchers have discovered that the current-creating strands of zinc oxide can be made longer and straighter -- and therefore more powerful -- when freed from gravity's unrelenting pull. That means nanowires grown in microgravity could lead to higher capacity batteries and the aforementioned juice-generating interstellar garb. Of course, there's no such end-products yet, but let's see if NASA can do what others have not: give pants-power to the people.
