Solar power is cheap and easy to access, right?
At least until someone takes control of the Sun (or a reasonable facsimile thereof)!
Considering that, even in the 1950s, we knew the Sun wouldn't die out for billions of years, you have to wonder when this story from Ace's Space Action #1 (1952) is set!
Apparently the unknown writer didn't know or didn't care, since no date is given.
But the art by Lou Cameron and Rocco Mastroserio shows technology only a couple of hundred of years ahead!
