Before we jump on the algae bandwagon, I hope there will be a systems analysis of the process in terms of pollution. Ethanol, for instance, is a gross polluter at every stage - consumption, putting out more pollutants than gasoline (maybe not diesel), in fermentation, putting out almost a pound of carbon dioxide for every pound of ethanol, and God knows how much in production - especially when coal-fired boilers are used to provide the heat needed. Every process is somewhat polluting, and we need trade it off - and choose the ones that are least polluting. On the surface, algae looks very promising.

I am interested to know about joint venture possibilities in tropical sub-saharan Africa. We are very interested.

Eugene,

Are you talking about corn/sugar based ethanol or cellulosic ethanol? Cellulosic is made from cellulose - grass stems, waste wood, etc.

Here's an article addressing soft biomass production of ethanol and the CO2 issue.

I think algae will bring a new era in the field of power. i want to know which area of the world are suitable for algae production. Is there any harmful effect of algae. Does it has any effect on agricultural field ? Which type of industry whethere small scale or large scale industry would be the algae. If it is a suitable for small scale it is benifited for some country like india for unemployment problems. I hope alge became our friendly energy.
thank you.

Thanks for the article...it is heartening to see algae getting a lot of publicity, something I feel they deserve.

I co-ordinate Oilgae.com ( http://www.oilgae.com ), a site that explores use of algae as a feedstock for biodiesel...While the math certainly appears to favor algae, there are a number of issues to be overcome. These have to do with (1) choosing optimal algal strains, (2) issues faced in cultivation and harvesting, and (3) cost-effective methods to extract oil and transform it into biodiesel.

So yes, there is still a long way to go before it can be proven with certainty that algal biodiesel can be cost-effective on a large scale, but I'm optimistic most of the above-mentioned issues will be overcome.
