This invention provides means for producing power by using isothermal compressors and isothermal expanders. One embodiment has an isothermal compressor that compresses air (or other gas), passes the air through a counter- flow heat exchanger, which heats the air, uses the heated air to drive an isothermal expander for power generation, and transfers the expander exhaust back through the counter-flow heat exchanger to heat the input air to the expander. Another embodiment has a boiler that produces vapor that flows through a counter-flow heat exchanger to superheat the vapor. The vapor then flows through an isothermal expander for power generation. The exhaust from the isothermal expander flows back through the counter-flow heat exchanger to supply heat to the vapor coming from the boiler and then flows through another heat exchanger that preheats the feed liquid flowing to the boiler.
