Abstract
Heat transfer fluid mixtures and methods of making and using same are presented. The inventive heat transfer fluid mixtures consist essentially of at least one light gas, such as hydrogen, and at least one heavy fluid, such as helium wherein the mixture will not be capable of mixing with air in any proportions to produce a self-sustaining flammable or combustible mixture, or wherein a concentration of hydrogen is sufficient to reduce cost of the mixture to an amount substantially less than cost of pure helium.
