New blog on seaweed-oil
I have a web site at http://floatingislands.com/seaweed-oil but it would be nice to get feedback and help from people, so I am starting this blog.

seaweed-oil
The goal is to make a seaweed with high enough oil content that farming seaweed for oil can be profitable.

I find your project interesting. We have included a link on our blog. Check out "Israeli scientists focus on farming seaweed for oil"
Description/Abstract
A pollution-free process to convert Dunaliella, a salt-water seaweed, to high-grade synthetic crude oil has been developed to a preliminary stage.^In the farming scheme, Dunaliella would be grown in a string of desert salt-water solar ponds, where it would have a most impressive growth rate.^The crop could readily be harvested with little mechanical energy.^In the laboratory-autoclave procedure, a high-temperature reducing gas converts an aqueous slurry of algae into oil, and alkaline catalysts help drive the reaction.^Oil yields have been called satisfactory.^The project has been split up into teams who will try to increase the efficiency of raising the seaweed, find the least energy-intensive harvesting method, genetically alter the algae to raise their organic content, and improve the conversion process.
Was hoping to see something more recent than March, 2006. Any updates?
Hi Vince, interested in your pages, will follow some of the links..
Perhaps the most promiscing way to produce fuel from seaweed is through the fermentation of mannitol and laminaran into ethanol, which will be addressed mainly to species of Kelp (Fucales, Sargassum, Ascophylumm, Laminaria, Macrocystis,etc.). Except for Sargassum, most of them are confined to temperate and cold water oceans where production is limited to summer months. It will be interesting to see any iniciative on the tropics
It looks as if oil production is a reaction to severe conditions for most algae. So the best conditions for growth are not good for oil.

I am working with micoralgae for biofuel production; the show stopper is that we cannot harvest the algae; all methods exceed the energy in the algae; this got me rethinking about macroalgae and I am glad to find others thinking along the same lines. Keep up the good work.
may i know that what macroalga can be biodiesel??and which macroalgas have yield 40%?? please reply me,thanks
There was a big study done years ago that found some species that were up to 40% oil. As another poster said, it seems to be when conditions are tough, not when conditions are good for growth. The following site seems to have lots of good info: http://peswiki.com/index.php/Directory:Biodiesel_from_Algae_Oil#Oil_Yield
