Electrical devices could be powered with ice-filled wires, say scientists
Electrical devices could soon be powered using ice-filled wires, thanks to MIT scientists including one of Indian origin, who have found that water can freeze solid even at high temperatures inside tiny carbon nanotubes. Water starts to boil at a temperature of 100 degrees Celsius. Scientists have long known that when water is confined in very small spaces, its boiling and freezing points can change, usually dropping by abound 10 degrees Celsius.
Scientists, including Kumar Varoon Agrawal from Massachusetts Institute of Technology in the US, have found that water can freeze even at high temperatures that would normally set it boiling in carbon nanotubes whose inner dimensions are not much bigger than a few water molecules.
