Kyzyl wants to know Carbon capture? 6 months ago
http://web.mit.edu/newsoffice/2011/carbon-dioxide-capture-1206.html
A new MIT study shows that, at least for the foreseeable future, proposals to capture carbon from the air are not realistic. Are you agree with this assertion?- View all 2 answers

Under an open pounds or a semi continuous culture system, this reality is correct; mainly due to two facts: low CO2(g) diffusion into culture medium and a very high culturing area are required. But with continuous culture systems, required culture area can be reduced at least by 10 times; culture time can be reduced from 3 - 4 weeks to 3 - 4 days and productivity increased 1.5 - 2 times. All these improvements do it viable Carbon Capture.

Narsi wants to know Flue Gases to Hydrocarbon Fuels - Challenges in Tech and Processes 10 months ago
I read about a company's (LanzaTech) efforts in converting flue gases to ethanol...
http://dev.sandbox.green.autoblog.com/2011/08/27/lanzatech-harsco-team-up-to-convert-steel-mill-flue-gases-to-et/
What are the technical and process challenges in converting flue gases to a range of hydrocarbon fuels?-
Flue gases are a very important source of CO2(g) for microalgae cultures for biofuels production. But, it´s so important verify and controlling SOx and NOx gases concentration into the culture medium. These gases causing serious damage to microalgae cultures.

Gaya3 wants to know CO2 Sequestrated using Algae 6 months ago
Happened to read this paper "Biotransformations of carbon dioxide in photobioreactors"(http://www.mendeley.com/research/biotransformations-carbon-dioxide-photobioreactors/#), it's abstract says: Despite large amounts of CO2 that were sequestered during the cultivation, it is demonstrated that only a small fraction (about 3%) was effectively fixed as microalgae biomass, indicating the existence of other routes of CO2 conversion in the photobioreactor.

Effectively, natural diffusion of CO2(g) into water is around of 3% and this is a normal concentration in open pound bioreactors due to they are open systems. But in PBR closed systems you can hiper saturated the liquid culture medium, when microalgae are in exponential grown, so that you can rise disolved CO2(g) concentrations as high as 15%, there is 5 times normal concentration. However you must to be account that these high disolved CO2(g) concentrations only can be supported by continuous culture systems.

It would be cool to have a gas pump that goes form the point of fuel processing to the garage too

Joshwolf wants to know what you think about a green roof 5 months ago
Would you place plastic tubing on top of your roof(facing south) to produce about a gallon of fuel a day?

What do you think would happen if you found the gene sequence responsible for the production of photosystems in algae and copied and pasted this protein into the gene sequence? Would there be more photosystem structures, and would that increase the efficiency of light capture?

Answer this question / Share a linkYour volume is tiny so the temperature stability needed to produce a consistent algae harvest from day to day will be difficult. Especially using any kind of direct interface. I recommend buying/building a small fluid-to-fluid heat exchanger out of plastic. FYI Georg Fischer Inc. manufactures a HUGE plastic heat exchanger. The total temperature swing from noon to midnight you seek to maintain is 3 deg. F. That's all you get and still have consistent algae produced from day to day.
