Why do photobioreactors cost 10 times as much as open ponds? Any idea? If we are able to clearly identify cost drivers, we could perhaps figure out how to lower the costs!

Any more updates on Algenol's so called low cost PBR?in Algae Fuels

In fact, when I read the whole thing again, I do not know how this could be classified as a low cost PBR...it appears that is more of a low cost process, wouldn't others agree?

Interesting link... It says that a tubular PBR was able to manage, to some extent "problems, such as contamination, pH adjustment, harvesting and introduction of nutrients, but there still light intensity, mixing, aggregation and temperature control, in addition to large space requirement are not resolved. Any photobioreactor design that can take care of some or all of the above problems will improve efficiency fairly well. A three dimensional photobioreactor (3dPBR) design that brings sunlight to the algae in a closed system instead of taking the algae to the sun in an open system could be the right solution. It should be able to optimize light intensity by tuning up the quantity of sunlight to suite a given experimental conditions, and contamination and water loss will be minimal. " The 3D PBT is something I have not read about much so far...does this design have the inherent potential to manage all the problems listed above?

This is why the price is so high for tube type bio reactors just think of how may feet of this it would take to cover an acre of space. This is the price per foot. http://www.usplastic.com/catalog/item.aspx?itemid=34565&catid=440 $11.21 per foot for 6" od acrylic tube.

Folks, what do you think of the concept discussed in the link http://www.che.utexas.edu/eldridge-group/pdf/Aditya.pdf - of a combination of open and closed systems?

@Akshaya, what is your advice for automation control system , Siemen or Mitsubishi, and what type.
