NOVELTY - The system has a cylindrical convex lens (1.26) placed at bottom of a vertical pipe (1.15) such that solar rays deflected by flat inclined mirrors (1.3, 1.5, 1.6) are concentrated by the lens mounted on top of Plano-concave lens (1.27) into coherent light beam. A cumulative solar ray beam is driven downwards through the pipe and the lens whose curved surface converts water (1.7) that is previously driven down through a separate pipe by gravity into steam at an area of light point such that the steam is driven upwards through another pipe by natural circulation to drive a steam turbine (1.17).    USE - Thermal solar power generation system for supplying power, heat and water for heating, industrial and commercial applications, and for use in mountainous areas, high altitude places, low altitude places, lake shores, sea shores, lakes, rivers, river sides, seas, canals, channels, canal shores, channel shores, ships, boats, submarines, trains, lorries, trailers, aircraft, air cushion ground effect vehicles, ground effect vehicles, maritime vehicles, naval vehicles, helicopters, airplanes, space planes, spacecraft, space stations, buildings, houses, factories, factory buildings, telecommunication towers, communication towers, airports, airport control towers, hospitals, tower blocks, towers, skyscrapers, quarries, mines, harbors, cranes, power stations, cooling towers, antennas, oceanographic vessels, icebreakers, offshore vessels, wind turbine offshore vessels, oil tankers, container vessels, solar thermal power generation offshore vessels, thermal power generation offshore vessels, offshore vessels, workboats, work vessels, tugs, marine vessels, oil rigs, oil rig towers, oil drilling towers, oil drilling vessels, industrial vessels, crane masts, cranes, wind turbines, wind turbine masts, signaling masts, signaling towers, railway signaling towers, railway signaling masts, traffic light masts, jack-up cranes, jack-up vessels, jack-up ships, jack-up rigs, rigs, barges, floating barges, sea barges, river barges, canal barges, railway catenary pillars, railway catenary masts, road traffic masts, road lighting masts, street lighting masts, pontoons, submersible pontoons, submersible barges, submersible vessels, submersible offshore vessels, bridges, bridge masts, dams, submersible wind turbine vessels, submersible solar thermal power generation vessels, desalination plants, offshore desalination plants, submersible desalination plants, semi-submersible desalination plants, semi-submersible barges, semisubmersible pontoons, semi-submersible vessels, semi-submersible offshore vessels, semi-submersible wind turbine vessels, semi-submersible solar thermal power generation vessels, icebreakers, shipyards, shipyard docks, dry docks, floating docks, semisubmersible docks and dockyards (all claimed).    ADVANTAGE - The system uses previous masts of a ship as the tower masts such that the mirrors can be retrofitted onto the previous masts of the ship, thus simplifying a design of the ship's propulsion and the system, and hence minimizing volume usage and weight, maximizing efficiency and minimizing drilling and digging costs with an offshore floating vessel to generate electricity. The system allows turbines to be connected to generators for maximizing power plant efficiency and uses hydroelectric and thermal power units for maximizing power output, while using only renewable energy and avoiding usage of pumps. The system is designed such that a cross-sectional area is greater at the area of contact of the concentrated light rays with the flowing water for driving the water to flow slower, thus maximizing heat transfer and evaporation efficiency. The vertical pipe drives the focused lined light beam downwards into the ground at exactly same position as the center line of the lenses so as to drive resulting magnified light beam down the channel and exactly at the center in order to maximize functional accuracy.
