Ice in a Box · San Evaristo, Baja California Sur

Solar ice and clean water for coastal communities.

A solar powered system that makes ice and safe drinking water for San Evaristo, a fishing village on Mexico’s Sea of Cortez, designed so other coastal villages can copy it.

How it works

Sun in, ice and water out.

01 · Input

Solar power

The system runs on the sun, so the village no longer depends on ice trucked in from La Paz.

02 · Output

Ice for fishermen

Fresh flake ice keeps the catch fresh and lets fishing families earn more for it.

03 · Output

Water for children

Desalinated seawater, treated to Mexican standards, is free for local children.

Built to last

A community enterprise.

Ice in a Box is run as a local enterprise, so income from ice pays for upkeep and the project keeps working long after it is built.

Ice sold→Income→Upkeep→More ice

Owned locally

Local fishermen run the system with training and support.

Designed to copy

Every step is documented so other coastal villages can build their own.

Cross-border

Rotary clubs in the United States and Mexico work on it side by side.

The village

San Evaristo, Sea of Cortez.
