Abstract
A cooling medium supply apparatus has a sensing means and a cooling medium pump mechanism which is powered by a gas turbine engine assembly. The gas turbine engine assembly is self-contained with a fuel supply, an ignition system and a starting system. The sensing means monitors the presence of a primary supply of a cooling medium, and on detecting a loss of the primary supply, actuates the gas turbine assembly to provide a secondary supply of the cooling medium.
