Good article. Thanks. I have read a prospectus from SunEcoEnergy. They plan to build a 160 acre algae farm in the desert area east of San Diego. Plan is to produce 44,000 gallons per acre foot per year. We are planning to design a 25 acre facility in Hawaii. It will utilize flue gas CO2.

Perhaps we should not use any land to "cultivate" algae, but use what we cause to bloom by accident.

The article implies needing land area about the size of Maryland, but every year an algae bloom the size of New Jersey results in a dead zone about that size off the US Gulf Coast. Why not just harvest that? I mean, its not like it can swim away from a net!

If someone does a good job of harvesting it, we solve two problems at once.

At this present time it takes more energy to propel the recovery vehicle then the gather the floating algae for fuel use.

Is this an opinion or do you have a reference?

In any case, automated sailing boats should collect algae cheaply, especially if they are used in a bloom induced in a HNLC (high nutrient, low chlorophyll) segment of the equatorial Pacific. Another option is to enduce pleasure sailers in the the gulf coast region to trail plankton skeins behind them while they tool around. Since fertilizer induced blooms are suspected of being causitive of the dead zones in the region, the activity would accomplish two things at once.

Just some thoughts.

I recall reading from a news item that the company BlueMarble has mentioned it cost about $180 per T to harvest macroalgae - now, that's a lot money, but with time could come down...

BlueMarble is trying to harvest macro algea from enclosed spaces with aboundant bioissues to be concerned about. Trawling for micro algae on a mid-ocean bloom may be much simpler and cheaper. Maybe not.

I'd like to encourage interested parties to try it out. They should start with a reverse net with a weave tight enough to exclude most stuff like small fishes and other mini-life but let microalgae thru. Then a close weave net to capture the algae.

It seems that the Gulf Coast region from mid Texas to about Pascagoula would be an interesting area to start. They have algae blooms, due to (they suspect) fertilizer run-off, that eventually die off and sink to the bottom where they contribute to dead-zones. If netting the algae can be done successfully, we solve two problems at once.

So, I am just a hick out in the sticks. But have been pondering the issue and wondered where the best resources might be found to investigate an open pond setup for a colder climate (60 day growing season, for personal use). I think I have a good food source for the algae. But want to know where to look for an algae that might work with minimal labor to grow the algae. I have plenty of water and land for the process, just wonder about the temperature requirements, if colder climate algae produce enough oil. If there is a strain of algae that is good with temperature variations.

Any thoughts would be helpful.

Thank You,
ybul

I have read that some algae can grow in the snow. Get an algae that grows locally in a lake or pond and experiment with that.

I'd like to know of algae strains that can grow well and fast in snow

Type in "snow algae" on the address line.
