Hydro-electrochemical power generators and associated methods

A hydro-electrochemical power generator, comprising:

• a solid-state electrolyte having a first end and a second end opposite the first end, wherein the electrolyte comprises a water bearing hygroscopic material;
• a first electrode in contact with the first end of the electrolyte;
• a second electrode in contact with the second end of the electrolyte;
• and
• at least one heat source coupled to one of the first electrode and the second electrode and configured to apply a temperature gradient across the first end and the second end of the electrolyte, and wherein the first electrode and the second electrode are configured to output a non-zero electrical voltage in response to the application of the temperature gradient.
