    In addition to what everyone else already said, it takes a tremendous amount of energy to pump water uphill.

        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?
