Revolutionary Cooling System Uses Lasers

Jan. 30, 2013 — With the latest discovery by scientists from Nanyang Technological University (NTU), current cooling systems which uses refrigerant harmful to the ozone layer could be replaced by a revolutionary cooling system using lasers.

This discovery, published and featured on the cover of the 24 January 2013 issue of Nature, could also potentially lead to a host of other innovations. This includes making huge Magnetic Resonance Imaging (MRI) machines, unwieldy night vision goggles and satellite cameras — all of which require extreme cooling systems — even more compact and energy saving.

This breakthrough in laser cooling technology can even lead to the development of almost sci-fi like computer chips that cool on their own, minimising heat and thus prolonging battery life for portable devices like tablets and smart phones.
