1. A method for generating power, comprising:
extracting at least a portion of a power cycle fluid from a turbine;
circulating the extracted power cycle fluid to at least one heat transfer device;
circulating an intermediate heat transfer fluid to at least two heat transfer devices;
exchanging heat between the extracted power cycle fluid and the intermediate heat transfer fluid to heat the intermediate heat transfer fluid;
circulating a power cycle fluid to a cooler or condenser to exit at about the lowest pressure and temperature of a power cycle;
increasing the pressure of the cooled or condensed power cycle fluid to a high pressure;
circulating the high pressure cooled or condensed power cycle fluid to at least one heat transfer device;
heating the high pressure cooled or condensed power cycle fluid by exchanging heat with the intermediate heat transfer fluid;
heating the intermediate heat transfer fluid by exchanging heat with a primary heat transfer fluid;
further heating the power cycle fluid by exchanging heat with the heated intermediate heat transfer fluid; and
circulating the power cycle fluid through a turbine to reduce the pressure of the power cycle fluid and generating power.
