Sister Alphonsine Ciza spends most of her day in gum boots, white veil tucked under a builder's hat, manning the micro hydroelectric plant she built to overcome daily electricity cuts in her town of Miti in eastern Democratic Republic of Congo.
She works around the clock with a team of nuns and engineers, greasing machinery and checking the dials of a generator that is fed from a nearby reservoir and lights up a convent, church, two schools and a clinic free of charge.
