Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) References are made, in the following text, to the accompanying drawings, in which:

(2) FIG. 1 is a procedural diagram; and

(3) FIG. 2 is a cross section of a natural stone plate stabilized with carbon fibers.

(4) One of the many possible implementations of the invention describes a material-chain or a substance chain circuit respectively with an arrangement of a conventional fossil burning (for example coal powered plant) fired power plant (1), whose exhaust gas separator (2) sequestrates the CO.sub.2 (3) and intakes it into a salt water tank (4), in which algae (6) grow with the help of sunlight (5), which are being collected. From the algae (6) vegetable oil (8) is being obtained in oil-presses (7), which is being processed at first in production plants (9) to become synthetic fibers and then with help of sunray-bundling driven pyrolysis being processed into carbon fibers (10).

(5) Woven fiber mats (11) are being produced from the carbon fibers.

(6) The energy for the pyrolysis process for the carbonation of the fibers is being provided by the sunlight (5) with the help of parabolic mirror technology. These carbon fibers or carbon fiber mats (11) are being combined with low energy winnable pressure-resistant materials such as natural stone (12) to become hybrid building and construction materials.

(7) The natural stone will be coated by the fibers with the help of epoxy resin, which is also being won from the algae oil, thus forming a CO.sub.2-neutrally won building material, from which, for example, more power plants (1), buildings and vehicles can be built. The energy being needed for the cutting of the stone and the production processes of the fibers and resin will be provided by the power plant (1).

(8) The conventional power plant (1) will be gradually replaced by power plants that are fired with renewable plant-based fuels instead of fossil burnings, in order to win the CO.sub.2 which is being bound within the renewably growing fuels from the atmosphere, by capturing the CO.sub.2 being bound in the renewable plant-fuels, in order to use it for the production of carbon fibers with help oft he algae growth. Hence valuable high performance tension stable building material is being derived from CO.sub.2 previously bound within the atmosphere, whereas the carbon is permanently bound within the building material.

(9) FIG. 2 shows the cross section of a natural stone plate (2) being stabilized with carbon fibers (1), being produced on the basis of algae oil, for the construction of buildings, vehicles, ships and other industrial and consumer goods using stabilization methods of natural stone by fibrous material, also known as “stone composite technology” or CFS “carbon fiber stone” respectively, when the stone is being coated under preload of the carbon fibers.

(10) Embodiments of the invention include a method for CO.sub.2-emissions neutral, in a second step associated with a CO.sub.2 emissions negative balance, production of pressure- and tension-stable building materials.

(11) By the process of energy production by burning of fossil or renewable burning materials, rapid growth of algae is being stimulated by sequestration of CO.sub.2, in order to utilize algae oil for the production of synthetic fibers, which are serving in particular for the production of carbon fibers to be further processed in such a way, that they are able to replace—in combination with natural stone for example—such CO.sub.2—intensive building materials like concrete, steel, glass and aluminum.

(12) The needed high temperatures for the production of carbon fibers will be generated in a CO.sub.2-neutral manner by help of bundling of sun rays with the help of for example parabolic mirror technology.

(13) This approach provides the fundamental basis for the formation of an initially CO.sub.2-neutral, later in time CO.sub.2-negative balance based further industrial development, in order to get control on and reverse global warming on Earth step by step over time.
