Ionic cooling system adapted for laptop use, scalded legs cautiously rejoice

Darren Murph

To be totally candid, we can't even utter the word "ionic" without thinking of Sharper Image, but the concept here actually seems like one that just might benefit the public at large... or at least those of us forced to cook our upper legs on a daily basis. San Jose-based Tessera, in cooperation with the University of Washington, has adapted an ionic cooling system for use in everyday laptops. The magic elixir consists of two electrodes, one of which is used to ionize air molecules such as nitrogen, while the other acts as a receiver for those molecules. According to reports, this method can extract around 30 percent more heat from a lap burner than the traditional "fan and more fans" approach. Still, a major obstacle remains in terms of ensuring that the electrodes remain reliable throughout the life of a laptop, but if Tessera has its druthers, some form of the system will be commercialized next year.
