H2E

Overview

H2E (Hydration to Everyone) was an early-stage Google X moonshot project exploring ways to improve access to safe drinking water by harvesting it directly from the air. The team created a solar-powered device that pulls water from the air and developed geospatial tools to map where such devices could meet daily water needs. After wrapping up, the team shared findings publicly in the H2E Collection.
