I am an active proponent of algae for a number of reasons. But what this company is doing will not work, for a whole bunch of reasons.

With various biomass (ie. not ethanol!) systems we can probably think about 1,000 gallons of oil energy equivalent per year.

Could you give more detail on this? What are the limiting factors?

Photo Bio Reactors (PBR's) are very cool. This is what you call the sealed combination of pipes and plastic and whatever that they are growing algae in in the video.

They are great for growing up a culture to use to innoculate an algae pond, or to cultivate small quantities of pure strains, etc.

But the value of algae generated for fuel in a PBR will not pay the capital costs of the PBR.

The winning strategy to grow low cost algae appears to be to grow in ponds.

OTOH, algae grown as a human health supplement or food is worth much much more than algae for fuel, and using a PBR may make sense.

A _major_ winning algae use is to use them for bio remediation. Running the exhaust from combustion based power generation (goal, natural gas, etc) through algae can serve to sequester CO2 - which is awesome.

Thank you. I am also an agae fan and am addicted to spirulina.
