Engineer Rodolfo Carrillo reported in August 2006 that solar box cookers are a great success in the plains of Venezuela. Cooperativa Wayne, R.L. developed a box-type solar cooker using aluminum obtained locally at low prices. The cooperative keeps track of every family that obtains a cooker, so that follow-up services can be provided. "The people that have gotten solar cookers are using them in an excellent manner," says Carrillo. People, mostly peasants, build their own cookers in the program and learn to both cook meals and pasteurize water with solar energy. The work of Cooperativa Wayne, R.L. has been covered by local and national newspapers. Other cooperatives have been in touch, seeking to spread solar cooking to their constituents.
