Algae to the rescueThe other pitfall is the cost per square foot of the bioreactor. Some designs apparently would work wonderfully but won't be competitive until we hit $15-$20 per gallon for gasoline. |

Since NM covers about 122,000 sq miles, ten pecent would be 12,000 square miles - not too far off from what we were discussing earlier. So I wonder if you misread that and it said 10,000 gallons per acre-year...? The US consumes about 146 billion gallons of gasoline each year. Using a 1:1 conversion, ignoring the advantages of going to diesel, and taking this over 12,000 sq miles, we would need about 19,000 gallons per acre-year. Factoring in the increased efficiency for diesel over IC engines would result in about a 30% reduction in the demand. |

On their website, they claim that a pond algae farm will produce 10k gal/acre yr. Since their system is vertical, they presumably get 10 times the output. Although I could not find the 100k number on their website. So that may be an interviewish kind of wishing number made up by the inventor. My spreadsheet has confirmed your numbers. Odd how an area just 100x100 miles can produce enough energy to run the nation. |

I've been thinking about this all day. |

So I'm curious about the process of turning the algae into biofuel. But if you're not into giving out trade secrets, when does your company go public?

There are plenty of strains of salt-water algae.

There are no simple answers, but many different approaches to each aspect of the process can be found.We hit a bit of a delay with the company but hope to be back on track shortly. |

It seems to me that one would want to stay in the coastal areas for both of the reasons that you cited - salt contamination and energy.
Why do it on land? |

But containment would be difficult, particularly in the open ocean and particularly during big storms. |

It has been suggested that the entire Salton Sea could be used for algae production, but I have no idea what the supply rate of water might be of if the idea is practical.
