MrSeb writes "General Electric has unveiled what seems to be the thinnest, high-performance cooler for the next-generation of ultra-thin tablets and laptops. While this cooler obviously allows for slimmer designs (or more space for other components), it also uses just half the power of a comparable fan, granting a significant boost to battery life. Oh, it’s almost silent, too. The technology behind GE’s cooler is called DCJ — Dual Piezoelectric Cooling Jets. DCJ basically acts as a miniature pair of bellows: Expanding to suck in cool air, and then contracting to expel hot air. GE originally invented DCJ to help cool commercial jet engines, but two years ago it seems someone had the clever idea of miniaturizing the tech for use in computers — and so here we are. GE’s cooler is roughly the size and thickness of a credit card, and the complete cooling solution (presumably including a heat sink/pipe) is 50% thinner than existing fan-based solutions. Perhaps most importantly, though, according to GE VP Chris Giovanniello, “DCJ can be made so quiet that users won’t even know it’s running.”"

  • Too bad that this technology arrived after most laptops and tablets have moved on using efficient processor architectures and other battery life extending technology to reduce power consumption and avoid the need for cooling fans altogether.

How many Unix hacks does it take to change a light bulb? Let's see, can you use a shell script for that or does it need a C program?
