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.
If the previous Alienware M11x R3 spec leak got you all giddy, then we have some good news for you: according to a manual dug up by one of our eagle-eyed readers, it appears that this year's M11x refresh will indeed be coming with second-gen Core i5 ULV and Core i7 ULV options, along with a faster DDR3 bus (1333MHz instead of 800MHz), a higher-res webcam (2MP instead of 1.3MP), an HD TrueLife LCD, and optional 3G / 4G mobile broadband. But of course, the real meat on this laptop is its graphics card, which turns out to be an NVIDIA GeForce GT540M with either 1Gb or 2GB of dedicated memory -- not bad for a laptop of this size. Unsurprisingly, no dates or prices are mentioned here, but given the early start of inventory clearance, it shouldn't be long before Round Rock reveals all. Dell (ZIP)
