Abstract
Utilization of solar energy by the production of steam within a cavity created between the surface of a sheet of water and a floating pontoon, the heat collected by a solar energy collector, placed on top of the pontoon, being transferred to the water itself by means of a heat exchanger, the solar energy collector being formed of a number of fixed transparent solid pieces each one comprising a black absorbing surface into which the sun's rays, refracted by the upper external surface and reflected inwards by the lateral surfaces, are concentrated.
Claims16
An apparatus for receiving, concentrating, accumulating and utilizing solar energy, to be located on a surface of water of a natural or of an artificial water source subject to sun rays, comprising a pontoon placed on the surface of water, said pontoon having an upper surface, a lower surface and vertical sides extending downwards into water;
- a solar energy collector positioned on said upper surface of the pontoon, said lower surface being spaced from the surface of water so that a cavity is formed between the surface of water and said lower surface and said vertical sides;
- and a heat exchanger located below the water surface and adapted to produce steam in said cavity, said steam being obtained from the action of thermal energy received by said solar energy collector from sun rays and passed to said heat exchanger which transfers the thermal energy to the layer of water above the heat exchanger.
