I wonder if solar panels could be feasibly built by a society that had no access to oil and internal combustion. Seems like a useful skip if possible.
@skryking If those are irreplaceable by other materials than a society without access to oil would be pretty screwed 😅
@mauve sure, copper+cupperous oxide panels are pretty easy to build
@rmond do they give a decent charge? I have no clue what types of matrrials are used in solar panels sadly. Though looked into tradeoffs between layouts and orientation relative to the sun's path.
@mauve oh no, of course they don't have a decent output else we'd see them in use all over given how simple the materials are. But it does meet the stipulations.
@mauve aren't there oil based products that are part of many solar cell systems?
