Creating Cold: The Chilling Challenge of Off-Grid Refrigeration for Developing Countries

Larry Bentley and F. Andrew Dowdy are trying to solve the problem of refrigeration for off-grid communities in developing countries. With distinguished careers, an impressive array of projects, and close to a century’s worth of combined experience in engineering and humanitarian work behind them, they’re looking for some out-of-the-icebox thinking on refrigeration. Issuing Engineers Without Borders USA’s first international Challenge competition, “The Chill Challenge,” they’re open to working with just about anyone—backyard inventors, colleges, and companies—to provide refrigeration to the hundreds of millions of people who get their power from off-grid energy systems.
