Having not seen sunlight in several million years, these craters have slowly accumulated vast quantities of water ice in a process called Random-Walk-Migration and Cryo-Trapping, and have therefore become the cores of modern Lunar settlement in the first half of the 21st century.
Power beaming was first used as a method for powering NASA's first robotic rovers in the search and mining of this ice and has developed into its current competitive form ...
