    I’m not sure how much power those different modules are capable of gathering, but based on this video from GreatScott! that tests similar-ish equipment, I’m guessing probably not a lot? except for the solar part. A small solar panel recharging a battery adequately sized to last the night should absolutely be able to keep a meshtastic node going.

    There is this video on using an insulated thermal mass with a peltier generator, attached, and that seems to be able to produce power fairly consistently, though according to spec sheet for that generator, it’ll only produce 119 milliwatts (0.19 watts) with a 30 degree temperature differential.

    All depends on the power that can put out, and the board requirements. Post an update if you decide to experiment.
