Is there ANY evidence that increasing the "surface area" exposed to
light, without increasing the light, increases algae growth rates
compared to simple raceway mixing? You know, the way people are
always talking about with "going vertical" or using "fiber optics to
disperse the light"?
Since hundreds of millions of dollars are being invested on the
assumption that this is true, it would be nice to see SOME evidence.
OK, I'll try again: Is there ANY evidence that increasing the "surface area" exposed to light, without increasing the light, increases algae growth rates ...

RAMON, You said Nannochloropsis, that is great green algae. I had a friend 's friend in AZ that got Rotifers in his algae and took over. Rotifers have very...

Ramon, Your set up sounds similar to ours. One thing I would caution is that adding NaHCO3 also increases salinity. Perhaps for the time frame that you're...
Ken, Two point you need to think about... CO2 forms an acid that will unite with the base to form a salt.. with a pH of 8.5 you will remove almost 100% of the...

Marcel, I think you misunderstood what was suggested. In a raceway pond, at any one moment, most of the algae cannot "see" the sun. The algae culture exhibits...
