Abstract

A solar steam producer has an inner container 1 and an outer container 6, the inner container 1 having a metal conductor 3 attached at a base. A convex lens 2 directs sunlight onto the conductor 3 for transforming water 4 in contact with the conductor into steam. The water level is just below the top of the conductor 3, and the inner container has apertures 5 so water may flow from the outer container 6 into the inner container 1. It is stated that the system will produce electricity by steam pressure opening a valve 8, the steam causing a mechanical force in a turbine, then resuming its water state, and then falling down to rejoin the body of water in outer container 6.

Description

2362458 A Solar Steam Production System.

This invention uses solar energy to create steam for the purpose of generating electricity.

Renewable energy (wind or water) is already an established means of driving the rotors necessary for turning mechanical force into electricity. However, there is also a need for smaller designs, which produce less voltage, but sufficient to supply individual cooler fans, and other electrically driven devices, the use of which does not contribute to the greenhouse effect.

According to the present invention, sunlight is used to provide steam under suffiient pressure to turn blades attached to a rotor, as constituted in a typical turbine electricity generator. This steam results from water being heated in a closed system, and as a result of being in contact with a metal element, heated directly by sunlight directed onto it by means of a convexlens.

Once the steam has reached a sufficient density, it pushes open a valve leading to a conveyor tube and the rotor blades, situated in a typical turbine generator. The steam then returns to water and descends through a continuation of the same tube back into the closed system, rejoining the existent water, through apertures in the inner container of the design.

A specific embodiment of the -invention will now be described by way of example, with reference to the accompanying drawings in which:- Figure 1 shows a cross section of the solar -steam production -System: Figure 2 shows the relationship of the inner and outer containers: Figure 3 shows the whole system, including a typical turbine generator, in the surround of a high strength plastic box.

Referring to the drawings, the steam production system comprises of (RTM) an inner container 1, constituted of a metal or glass (teflon) bowl, at the top of which is a convex lens 2, which directs sunlight onto a metal conductor 3, attached to the base of the container 1. This container holds water 4 to a level just below the top of the conductor 3, and has a number of apertures 5, accessing water in the outer container 6, (that is, allowing free flow of water between the two). The inner container also has a single outlet, which is in the form of a tube 7, and through which steam, resulting firom water contacting the metal conductor 3, passes. Where the tube leaves the inner container 1 is a valve 8, ensuring the steam is under sufficient pressure before it escapes into the tube 7. The pressurised steam conveys itself through the tube 7, to cause a mechanical force in a typical turbine system and, resuming its water state, falls down and back into the outer container 6 and joins the total body of water existing in the two containers.

Claims

Claims.

1 A solar steam production system, comprising of water, in contact with metal conductor, heated by sunlight, directed onto it by means of a convex lens, and resulting in steam, pressurised to the extent that it is forced through a valve into a tube which articulates with a typical turbine electricity generator, and then returns as water to the original body of water from which it originated.

2. A solar steam production system as in Claim 1, constituted of two containers, allowing free flow of water between them by means of small apertures in the side of the inner one.
