Water-boiling goes high-tech

Speaking of boiling water, researchers in New York have developed a high-tech coating that could produce kettles and pots that would boil water super-fast and ultra-efficiently:

A new study from researchers at Rensselaer Polytechnic Institute shows that by adding an invisible layer of the nanomaterials to the bottom of a metal vessel, an order of magnitude increase in efficiency is achieved in bringing water to boil. This increase in efficiency could have a big impact on cooling computer chips, improving heat transfer systems, and reducing costs for industrial boiling applications.

"Air trapped in the forest of nanorods helps to dramatically boost the creation of bubbles and the efficiency of boiling ...."
