A development charity distributes reflective panel solar cookers to off-grid rural households that would otherwise cook over open wood or charcoal fires, shown in Figure 1. The cooker is a lightweight curved reflector that focuses sunlight onto a dark cooking pot, needs no fuel and no electricity, and can also pasteurise drinking water. The charity trains one village at a time to build, use and maintain the cookers from low-cost materials.
