Dime Sized Fan Can Cool Laptop |
|
Tuesday, 18 March 2008 |
Engineers harnessing the same physical property that drives silent
household air purifiers have created a miniaturized device that is now
ready for testing as a silent, ultra-thin, low-power and low
maintenance cooling system for laptop computers and other electronic
devices.
