A Robotic Algae Harvester (RAH) of the present invention works by providing a CO₂ collection mechanism that is installed in power plants or vehicles. These systems are available using current technology and have been proven to be scalable. CO₂ is then transported to RAH using ships. The RAH will feed and re-circulate algae broth through the photobioreactors (PBRs). The PBRs float in the ocean while the algae through photosynthesis will transform the CO₂ into biomass in a continuous process. The extracted algae will processed into a stable mix of oil and bi-product and transferred to the ship that brought the CO₂. The algae is then processed onshore in some of the following manners: converted to biodiesel via transesterification; converted to bio-ethanol via fermentation; burned for electricity generation; and/or used as protein for animal feed or food products.
