A heat engine utilizing heat to create a high pressure gas, said heat engine comprising:

• a first actuator, said first actuator being a double acting actuator and having a first actuator stroke length, said first actuator having a decreasing power output after a first actuator valve closes and as a first amount of the high pressure gas expands within said first actuator to move a first actuator head;
• a second actuator, said second actuator being a double acting actuator and having a second actuator stroke length, said second actuator having a decreasing power output after a second actuator valve closes and as a second amount of the high pressure gas expands within said second actuator to move a second actuator head;
• a first shaft;
• and
• a second shaft;
• wherein:
• said first actuator is coupled to said first shaft and to said second shaft;
• said second actuator is coupled to said first shaft and to said second shaft;
• said first shaft turns in a single rotational direction;
• said first actuator is operable independent of said second actuator to turn said first shaft in the single rotational direction;
• and
• said first actuator is operable in an offset phase relative to said second actuator.

A heat engine utilizing heat to create a high pressure gas, said heat engine comprising:

• a first actuator with a first actuator interior length and having a constant first actuator diameter along said first actuator interior length, said first actuator being a double acting actuator, and being operable with a first actuator first clutch and a first actuator second clutch, said first actuator being operable by expansion of the high pressure gas against a first actuator head;
