Tule canoes were used in ocean lagoons from Tomales Bay and Point Reyes National Seashore south to perhaps Monterey Bay. Tule–reed boats were used in lakes, bays and slow-moving rivers in much of Northern California. They were used by the Pomo living in the Laguna de Santa Rosa and Clear Lake, Tule Lake and other areas.
Early steamships were fueled by wood, later ones by coal or fuel oil. Early ships used stern or side paddle wheels, which gave way to screw propellers. The first commercial success accrued to Robert Fulton's North River Steamboat (often called Clermont) in US in 1807, followed in Europe by the 45-foot (14 m) Comet of 1812. Steam propulsion ...
The first known patent to extract energy from ocean waves was in 1799, filed in Paris by Pierre-Simon Girard and his son. [8] An early device was constructed around 1910 by Bochaux-Praceique to power his house in Royan, France. [9] It appears that this was the first oscillating water-column type of wave-energy device.

Solar powered boats have been used successfully at sea. The first crossing of the Atlantic Ocean was achieved in the winter of 2006/2007 by the solar catamaran Sun21. [42] [43] (see also List of solar-powered boats)
Marine energy, also known as ocean energy, ocean power, or marine and hydrokinetic energy, refers to energy harnessed from waves, tides, salinity gradients, and temperature differences in the ocean. The movement of water in the world's oceans stores vast amounts of kinetic energy , which can be converted into electricity to power homes ...
The California Electric Company (now PG&E) in San Francisco in 1879 used two direct current generators from Charles Brush's company to supply multiple customers with power for their arc lamps.

SS California was the World's first major ocean liner built with turbo-electric propulsion. [9] When launched in 1927 she was also the largest merchant ship yet built in the US, [10] although she was a modest size compared with the biggest European liners of her era. In 1938 California was renamed SS Uruguay. [2]
