What element would turn green in the presence of light?
Copper turns green in the presence of light and air. Maybe plumbers are a life form that used to exist on Mars.

To the best of my knowledge, the air needs to have oxygen in it to oxidize the copper and cause the verdigris (green color).Copper turns green in the presence of light and air. Maybe plumbers are a life form that used to exist on Mars.

For the first time in the history of space exploration, scientists have measured the seasonal changes in the gases that fill the air directly above the surface of Gale Crater on Mars. As a result, they noticed something baffling: oxygen, the gas many Earth creatures use to breathe, behaves in a way that so far scientists cannot explain through any known chemical processes.
Over the course of three Mars years (or nearly six Earth years) an instrument in the Sample Analysis at Mars (SAM) portable chemistry lab inside the belly of NASA’s Curiosity rover inhaled the air of Gale Crater and analyzed its composition. The results SAM spit out confirmed the makeup of the Martian atmosphere at the surface: 95% by volume of carbon dioxide (CO2), 2.6% molecular nitrogen (N2), 1.9% argon (Ar), 0.16% molecular oxygen (O2), and 0.06% carbon monoxide (CO).
So, lots of potential for wind farm? All we’d need is a really long cable to get it back to earth.
Cool, a message, and also JPL's coordinates on earth. The martians will know exactly where to go when they complain about this littering.
