We're in the far north-western tip of Zambia near the border with the DRC, and of all the bitcoin mines I've visited - this one is the strangest.

Water and electronic equipment don't usually mix well but it's precisely the proximity to the river that's drawn bitcoiners here.
Philip's mine is plugged directly into a hydro-electric power plant that channels some of the Zambezi's torrent through enormous turbines to generate continuous, clean electricity.
