David is a 51-year-old U. S. citizen who has lived in Bolivia for a number of years. He is a small entrepreneur who speaks very fluent Spanish in the Bolivian idiom. He is remarkable for his dynamism and his strong social and ecological conscience.

David and his Bolivian wife Ruth have undertaken a private crusade on a shoestring to introduce solar ovens and other alternative energy appliances to people across Bolivia. Because of widespread poverty and the increasing scarcity and expense of traditional fuels, his efforts have been well received wherever he goes.

During more than four years, David has honed the method of presenting alternative technologies in the cities as well as in the countryside. Read more about David and Ruth here.
