Power generator

Apparatus utilizing the volumetric expansion of water upon its change of phase for generating power, said apparatus comprising:

• a chamber having heat transmitting, fluid impervious, flexible walls, said chamber being filled with water;
• a housing having an internal cavity in which said chamber is located, said housing having pressure-containing walls spaced from said flexible walls of said chamber;
• a fluid filling such space between said pressure-containing walls and said flexible walls;
• means for circulating said fluid through said internal cavity in such space;
• a conduit connected to said housing in fluid communication with said interior cavity;
• means for changing the phase of the water in said chamber between its liquid phase and its solid phase, whereby when said water is changed to its solid phase, the volume of said water expands thereby expanding said flexible walls of said chamber to displace a proportional amount of fluid from said housing into said conduit;
• and
• means associated with said conduit for utilizing said displace moving fluid as a power medium to do work.
