Hai,
I am also thinking of possible water source in desert? I wonder how effectively we can cultivate algae in desert where we get plenty of land & sunlight but less amount of water and evaporation problem?

I think we can use closed systems.....It'll reduce the rate of evaporation.

What about using a closed loop bioreactor system? It offers low evaporation rate and requires only less water compared to other systems hence it is suitable for desert cultivation.

Refer this link...

"Valcent's HDVB Bioreactor system can be deployed on Non-arable land requires very little water due to its closed circuit process".

I want to know how cost effective it is?
I have read,

The Vertigro system is not cost effective and is logistically challenged! The numbers don't add up. According to the people I have spoken with there is not enough sun to produce 100,000 gallons per acre with algae. Maybe 60,000 in a perfect world but at $1,000,000 per acre this is not a cost effective solution unless you can find an investor that likes a twenty year return on investment.

One more company here,

Algatech, a leading Israel company also uses closed photobioreactor systems to have control over adverse climatic conditions in desert region. They use tubular solar-powered photobioreactors in closed, strictly controlled systems. Algatech produces its Astaxanthin from the microalga Haematococcus pluvialis according to its patented biocontrolled growing process. The plant is located in the southern part of Israel, in the Negev Desert, thus exploiting the area's high solar radiation year-round.

I have read somewhere in a forum that their pilot facility in Texas cost $2.5 million for a 6 acre facility. This test bed facility produced about 54,000 gallons of biodiesel in 90 days. At around $3/gallon for regular diesel, this alone would have earned them about $150,000. It would make profit it seems…..

Thanks for the info Mak,

By the way, I came across an article on "Desert dust enables algae to grow"

http://www.innovations-report.de/html/berichte/biowissenschaften_chemie/bericht-24390.html

I understand that desert dust enables algae to grow . Does this fact help algae cultivation in desert in any way?
