About Powering Agriculture

Powering Agriculture: An Energy Grand Challenge for Development supports the development and deployment of clean energy innovations that increase agriculture productivity and stimulate low carbon economic growth in the agriculture sector of developing countries to help end extreme poverty and extreme hunger.

Rebound Technologies intended to use its Powering Agriculture funding to demonstrate their off-grid refrigeration system, known as SunChill™. The system is intended to increase agricultural productivity by removing field heat from crops and providing continued cooling at local markets or central processing facilities.

The first step in the project was to design, build and test a prototype system in their United States-based lab located in Colorado. This was followed by the building, implementation and refinement of a demonstration unit in Mozambique.

By March 2016, Rebound had validated its SunChill™ field demonstration unit, constructed from locally sourced parts, at their project partner Mozambique Organicos, a for-profit farm located in Inhambane Province, Mozambique. Mozambique Organicos also serves as an incubator, teaching farming skills to local women. A local farmer was trained to operate the system, and it was operated continuously, confirming the reliability of the cooling cycle and the viability of the product. The total project effort resulted in the completion of the engineering work that forms the technology foundation. Remaining is the industrial design work necessary to move SunChill™ to a commercialized product available for deployment. Rebound plans to Open Source all SunChill™ engineering documents by the end of 2017, allowing students and entrepreneurs to leverage Rebound’s lessons learned and transition them into a successful, marketable product.
