    But they don’t have anything to do with the moon. They harvest energy from Earth’s black body radiation

        That’s a good one!

        I was thinking, Earth’s radiation is solar energy, emitting back into space after being absorbed. So a normal solar panel gets solar energy coming down, and this thing gets solar energy going back up. So “reverse” or “upside-down” make sense from that perspective. But wind and hydroelectric also harvest solar energy indirectly. Should we call the sideways solar panels? So yeah, I think “terral” avoids a rabbit hole of madness.
