The mechanism, from the book

The sun shines on every roof and the island imports its fuel.

Every idea in cluster 21 uses this mechanism.

A first step

Sit with 10 smallholders in one farming area and ask how they pump water now, what they spend on fuel or electricity each season, and how often the pump breaks. Get a supplier's quote for a solar pump installed, then offer it with a yearly maintenance contract and a repair promise. The proof is a farmer paying a deposit, or a farmers' group ordering together.

Who pays first
A smallholder who spends heavily on fuel for a diesel pump each season and has lost a crop when the pump failed at the wrong time.
What leaves today
Diesel for pumping is imported and paid for every season; a solar pump with a maintenance contract replaces that import with sunlight and a local mechanic.

The idea and the mechanism are from the book. The first step was written for this site as a suggestion; if you know a better one, say so.

The test

Does it keep value that now leaves the island, or build the proof that lets somebody else do so?

The only test any idea on this site has to pass. The four rules that go with it are here.
