This article reports that a Japanese construction firm, Shimizu, has dreamed up a rather ambitious plan for harvesting energy from the Moon:

It’s a large-scaled, seemingly inconceivable plan that involves remote-controlled robots building thousands of photovoltaic panels out of moon dirt, assembling the panels into a gigantic lunar girdle belt, and laser-beaming 220 terawatts of annually collected voltage toward Earth.

Supposedly this is actually possible but a plan that involves robots turning Moon Dirt™ into solar panels seems beyond "seemingly inconceivable" and lands in "downright ludicrous." Maybe one day Shimizu will prove me wrong but this is craziness! (of the best variety)
