I stumbled across this while researching the wisdom of our ancestors.
It’s a page from Kenyon college in Ohio on thermo electric batteries. These are not Peltier effect devices, they use the Seebeck effect, the opposite of the Peltier effect.
What caught my attention was these two passages: “We rarely mention the Seebeck and Peltier effects to introductory students today, but in the middle part of the century the thermo-electric battery was often used in place of galvanic batteries” and “Generators of this type were used ca. 1900 to charge storage batteries”.
Thermoelectric Battery
If that 5 stack device can charge 1.5 volt storage batteries then each junction only has to produce 17 mV (5 x 18 junctions per stack)
Digging further I found this pdf.

This stuff is giving me ideas to experiment with combining the two effects. Generate current with the Seebeck junctions, send it back through Peltier junctions and use the produced heat and cold to reinforce the temperature differential of the Seebeck junctions. Maybe use solar heating during the day with heat storage (concrete/gravel) to rev it up and use the Peltier to help keep the heat & cold going at night & on cloudy days. A 24/7 Solar-Seebeck-Peltier generator.
You know, .. this could be built on a shoe-string budget.
Possibilities.
