What is the term for a water pump system that uses the energy from children at play to pump water?

• A. Playpumps
• B. Windpumps
• C. Solar pumps
• D. Handpumps

Answer: (A)

The main idea here is using energy generated by people—in this case, children playing—to power a water pump. A PlayPump system connects a playground device, like a merry-go-round, to a pump. When kids spin the ride, their motion drives the pump, lifting water from a borehole into a storage tank for nearby households or schools. This makes water access part of a fun activity, turning play into a practical service. Why this fits best: the energy source comes from children at play, which is the defining feature of a PlayPump. The other options rely on wind, solar energy, or direct manual effort by a person, none of which involve capturing energy from children at play.
