Gravity Battery Playground
Kids lift the weights by playing; the weights light the street.

The Vision
A climbing tower where every ascent, swing and seesaw stroke winches steel counterweights up a mast. At dusk the weights descend for hours, generating enough to run the playground's own lights and a phone-charging bench. The energy is a rounding error; the lesson - effort, storage, light - is the payload.

The Long Story
Yes, the physics is humble: an afternoon of vigorous play stores about as much energy as a laptop battery. Anyone pitching playground power as grid infrastructure is selling you something.
But walk past at night and the argument changes. The lamps are on because children lifted mass against gravity all afternoon, and every kid on the street can explain exactly how. It is the cheapest energy literacy program ever built, disguised as the best climbing tower in the district - and the maintenance contract doubles as a shop-class apprenticeship.
