System and process for extracting energy from heat

A system comprising:

• a turbine;
• a first fluid;
• and
• a second fluid, wherein the turbine comprises
• a. a rotor assembly comprising at least one first rotor and at least one second rotor affixed to a shaft and within an enclosure configured to contain the first fluid and the second fluid, wherein
• the at least one second rotor is positioned on the shaft downstream of the at least one first rotor,
• the at least one first rotor is configured to draw the first fluid into the turbine,
• the at least one second rotor is configured to extract energy from a mixture of the first fluid and the second fluid by contacting the mixture and providing rotational energy to the rotor assembly, and
• the at least one first rotor and at least one second rotor are also configured to mix the second fluid with the first fluid to form the mixture,
• b. a first fluid inlet positioned upstream of the at least one first rotor,
• c. a second fluid inlet positioned between the at least one first rotor and the at least one second rotor and configured to direct the second fluid into the turbine,
• d. a fluid outlet positioned downstream of the at least one second rotor, and
• e. a gas outlet positioned downstream of the at least one second rotor,
• wherein the energy in the mixture provided to the at least one second rotor results from vaporization and expansion of the second fluid resulting in pressurization of the mixture.
