Synopsis
Lighthouses, once vital for navigation, are contrasted with modern global navigation satellite systems (GNSS) in a critique of Western navigation methods and their impact on global trade.
Synopsis
Lighthouses stand as relics of a past era in navigation. "Sunstone," directed by Louis Henderson, traces the shift from traditional optical navigation methods to modern global navigation satellite systems (GNSS). The film discusses the role of Fresnel lenses in lighthouse design and contrasts these historical practices with contemporary algorithms. It critiques Western navigation methods and reflects on how technological changes affect global trade. Produced in France and Portugal, the documentary runs for 40 minutes and is presented in Portuguese.
