A playground would be constructed with a merry-go-round that is connected to a battery powered filtration system. The unfiltered water would come from a "dirty water reservoir" in which people could pour their dirty water that they want to have purified. The kinetic energy from the children that play on the equipment would then charge the battery, allowing the pump to be used at anytime necessary. The filtered water would then be sent to a clean water reservoir from which residents can collect purified water.

We have discussed your idea in class and everyone thought it was great.

Not only in terms of the beneficial outcome with regard to fresh water, but also in terms of an emotional, playful concept.

The only question that remains is: How can these things get maintained?
