TECHNOLOGY FOCUS - BIOLOGY - Preferred Method: The carbon dioxide is collected through collection unit installed on power plant or heating source or motorized unit for transportation. The method further involves transporting the extracted algae to an onshore location, and processing the extracted algae onshore. The extracted algae are (i) processed to transesterification or fermentation process, or (ii) burned for generating electricity or direct fuel source.    TECHNOLOGY FOCUS - MECHANICAL ENGINEERING - Preferred Method: The method further involves autonomously controlling the location of a platform moving to zones with high photosynthetically active radiation, and submerging the photobioreactors in cases where the weather or sea conditions could damage the system. Preferred System: The system further comprises (i) unit for using the energy generated by wave, wind, or solar energy to move the platform to zones with high photosynthetically active radiation or to optimize photosynthetically active radiation, unit for using the energy generated by the waves to provide algae broth pumping to minimize photo-saturation, de-oxygenation, pipe cleaning and the power needs of the system, (ii) unit for using the amount of carbon dioxide or air mixture available in the system to change the buoyancy of the platform and photobioreactors, (iii) unit for circulating water through the photobioreactors to prevent photosaturation, to enrich the broth with carbon dioxide, to reduce the amount of oxygen and to clean the surfaces, (iv) conventional pump to pump the algae broth or (v) triangular shaped photobioreactors organized into hexagons. The system provides unit for oceans waves to directly pump the algal broth, or utilizing recaptured carbon dioxide to feed the algae at a rate to maintain its growth. Each triangle shaped photobioreactor comprises water inflatable tubes in its periphery for compression support, where the each triangle shaped photobioreactor includes air pockets to provide buoyancy control. The water inflatable tubes include a tensioned wire frame core for rigidity and to hold algae tubing. EXAMPLE - No suitable example given.
