Capturing the Ocean''s Energy
Way back in Napoleonic Paris, a Monsieur Girard had a novel idea about energy: power from the sea. In 1799, Girard obtained a patent for a machine he and his son had designed to mechanically capture the energy in ocean waves. Wave power could be used, they figured, to run pumps and sawmills and the like. These inventors would …
