I was involved peripherally with a project that provided solar ovens to grandmothers in Lesotho (because of AIDS grannies often end up looking after their grandkids). They were a tremendous problem in a country where deforestation and poverty are both major problems. BTW the solar ovens that are made in South Africa are paid for by the Raging Grannies group in BC, so a good connection between grandmothers.
Finished the circumnavigation in early February in Grenada. Have to work on a book project for the next several months so the boat will be waiting for next year.
