        Why? They have dump trucks and dams in Africa, you know. Or did you think this was before Africa became the world’s fastest-growing and biggest market for cell phones?

        Even as a slave, the cost of a human work is magnitudes above the cost of using a pump with petrol. A slave may be able to output ~1kWh per day, that’s mostly a few 10s of cents anywhere. Can you feed anyone on that?
