Thermo-electric device to provide electrical power

A thermopile for generating electric current wherein:

• a thermopile constructed of two selected materials, thermoelectric material (1) with a first Seebeck Coefficient property and thermoelectric material (2) with a second Seebeck Coefficient property such as to create a thermocouple;
• wherein slots are created in thermoelectric material (1) sheet such that strips of material remain between the slots of the sheet and slots are created in thermoelectric material (2) sheet at an angle in relation to the slots of thermoelectric material (1), with an electrically insulating material separating the two materials such that the ends of the sections of thermoelectric material (1) and thermoelectric material (2) over lap and are in contact with each other, on both sides of the assembly, at specific selected points forming a zig-zag pattern of sections of thermoelectric material (1) and thermoelectric material (2) creating a series of thermocouples;
• wherein every overlapping section end is fastened together in electrically conductive contact to form a thermocouple at these points of overlap only;
• wherein when fully assembled the assembly comprises a selected number of thermocouples and can be called a thermocard;
• wherein multiple said thermocards can be electrically connected in selected patterns;
