TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The intermediate products and end-user products comprises lipids, proteins, biodiesel fuel, alcohol, food grade microalgae. The algae are microalgae and macroalgae.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The gaseous environment includes only gas or a mixture of the gas and liquid. The gas comprises the carbon dioxide and water in gas phase, and where the liquid of the gaseous environment comprises water provided by a spray or mist. The carbon dioxide gas is provided in a concentration of 300-10000 ppm. The gas density of carbon dioxide in the gaseous environment is higher during at least one of the light periods than during at least one of the dark periods; is 300-600 ppm during the light period and during the dark period. Preferred Method: The method (M1) further involves: forcing carbon dioxide gas at the algae and substrate to increase the absorption of carbon dioxide by the algae; forcing gaseous water gas at the algae and substrate; harvesting a portion of the algae from the substrate; moving the substrate during the growth of the algae to increase exposure of sunlight to the algae; harvesting a portion of the algae from the substrate while the substrate and algae are being transported and leaving a portion of the algae to continue to grow for subsequent harvesting; reducing the exposure of light upon the algae and substrate such that the algae and the substrate is exposed to at least one light period and at least one dark period. The liquid applied to the algae and substrate involves: at least one of water, tap water, filtered water, distilled water, deionized water, and polluted water. The applying of light step involves: apply light from non-sunlight light sources. The harvesting leaves at least 50% of the original biomass as inoculum for further growth. The harvesting involves: at least one of cutting with a mechanical knife, air knife, or saw, brushing, or vacuuming and pressing off the algae with rollers. The method further involves: drying the harvested algae; processing the harvested algae to produce at least of one of intermediate products and end-user products.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The substrate comprises at least one of a woven fabric and a nonwoven fabric; polyester spunbonded nonwoven fabric; a grid substrate having spacing of 1-10 mm. The substrate comprises variable porosity, texture or capillary properties and has a thickness of 1-10 mm. The substrate and algae are transported during the growth of the algae. The substrate provides a surface area of greater than or equal to 80 square meters per each square meter of floor space of the enclosure. EXAMPLE - No suitable example given.
