The Solix Biofuel, a Boulder Colorado, is working with the Colorado State University for the production of biofuels made from algae grown in bioreactors consisting of plastic containers. The process uses sunlight, heat and carbon dioxide; to improve the process, the system is maintained in mechanical agitation, so that the mass plant receives uniformly sunlight.

According to the employees to the project efficiency of photosynthesis in this case is 10%, whereas normally the vegetation can absorb a maximum of 2% of solar energy incident.

In August 2006 another company, the Spanish Bio Fuel Systems, in collaboration with the University of Alicante, announced that it had developed a particular photo-bioreactor even more efficient.
