Systems and methods for a power-generating thermogalvanic brick

1. A thermogalvanic brick comprising:

an outer casing defining an interior surface and exterior surface forming an enclosure;

an all-plastic three-dimensional interior structure disposed within the outer casing and immersed in an electrolyte, wherein the three dimensional interior structure defines a lattice configuration and wherein the three dimensional interior structure is load-bearing; and

a first electrode and a second electrode disposed on opposite sides of the three-dimensional interior structure;

wherein a potential difference is induced between the first electrode and the second electrode when a temperature difference is present between the first electrode and the second electrode.

2. The thermogalvanic brick of claim 1 , further comprising:

a USB port in communication with the outer casing, wherein the USB port is in operative communication with the three-dimensional interior structure for providing an output of power generated by the three-dimensional interior structure.

3. The thermogalvanic brick of claim 1 , wherein the lattice configuration comprises a triply periodic minimal surface configuration.

4. The thermogalvanic brick of claim 1 , wherein the three-dimensional interior structure is immersed in a gelled or liquid electrolyte.

5. The thermogalvanic brick of claim 1 , wherein the outer casing comprises a plastic material.

6. The thermogalvanic brick of claim 1 , wherein exterior solar heating of the thermogalvanic brick has a controlled solar absorptivity, orientation, and shading to maximize the temperature difference between the exterior and interior surfaces of the thermogalvanic brick.

7. The thermogalvanic brick of claim 1 , wherein the material of the three-dimensional interior structure is acrylonitrile butadiene styrene.

8. The thermogalvanic brick of claim 1 , wherein the three-dimensional interior structure and electrolyte are thermally-insulating.
