The company is combining many technologies to move to direct creation of biofuel precursor liquids.  The algae is similar to that others are experimenting with but excrete the molecules into the water instead of retaining inside the cells.  This way the harvesting ‘only’ entails fractionating the liquid from the flow.  The bioreactors are essentially double panel windows with the algae filled liquid flowing inside.  The water gets CO2 from a power plant which scrubs it out of the plant effluents and one guesses that in cooler climates the water could be warmed in the cooling cycle of the same power plant so the system could operate year round.

The company calculates that their system can produce a great deal more, more easily refined biofuel precursor liquids than the alternates. Which mostly involve growing various kinds of plants and then converting them to biofuels in either chemical or bio reactors.
