Sam Brown and his wife, Tara Miller, first introduced solar cookers (and solar electric) to Taquile Island on Lake Titicaca Peru in 1996. Lake Titicaca is located at the northern end of the Altiplano basin, high in the Andes on the border of Peru and Bolivia. They have continued to return to visit every couple years, becoming godparents and developing a close and lasting relationship with the local community.
When they visit, they will be keeping a travel blog to chronicle their adventures and solar cooking experiences. Some introductory postings are at their Amigos de Taquile travel blog. Those interested, can sign up to follow the blog and be alerted to new postings.
