General Electric (GE) wants to replace your laptop's regular fan with a miniature set of bellows it calls Dual Piezoelectric Cooling Jets (DCJ). Initially developed for use in jet engines, the system works a bit like a diaphragm: it expands to pull in hot air before contracting to rapidly expel it, cooling the air in the process. GE says that, in addition to consuming half the power of a regular fan, its new tech is more than half as thin, enabling cooling systems that are only 4mm tall. Because of the comparatively simple construction, it'll apparently offer higher reliability rates than conventional cooling methods as well. The company says DCJ is virtually silent, and will enable "thinner, quieter, and more powerful tablets, laptops,...
