Algae instead of corn for bio-fuel

Do you know that oil derived from algae is an exciting renewable fuel possibility? - see Oilgae for more.
Here's an interesting Letter to the Editor @ MyWebPal
Algae instead of corn for bio-fuel
19 Mar 2007
"Dear editor:
Algae multiplies so quickly and produces so much oxygen per square foot that ponds with a total surface area five times the size of Colorado would be enough to start to reverse our growing CO2 problem.
Algae triples in volume every day. Corn, with one crop per year, nets approximately 81 gallons bio-diesel per acre (soy nets 40). Algae yields as high as 15,000 gallons per acre.
Enough bio-diesel to replace all petroleum transportation fuels could be grown in approximately 9.5 million acres — far less than the 450 million acres used for crop farming in the U.S., and the over 500 million acres animal grazing land.
Hydrogen is dangerous (explosive), extremely expensive, and nets zero energy — that is, it uses more energy than it creates.
Algae converts CO2 to O2; is 30-50 percent oil; and converts easily to bio-fuel.
Conservation reduces present and future production of CO2. Algae reduces existing CO2.
The government needs to quit looking at corn and begin massive and wholesale funding and grants for algae.
A new state agri-business of algae farms? Or grants for ocean farming? Algae, pond scum also a planet saver? Yes, if we take action.

Oilgae - Oil & Biodiesel from Algae

algOS - Biodiesel from Algae Open Source
About Oilgae - Oilgae - Oil & Biodiesel from Algae has a focus on biodiesel production from algae while also discussing alternative energy in general. Algae present an exciting possibility as a feedstock for biodiesel, and when you realise that oil was originally formed from algae - among other related plants - you think "Hey! Why not oil again from algae!"

I agree. Corn ethanol is so 1970's Arab oil embargo 'gasahol'! Leave it to the U.S. gov't to drag up 30 year old technology. But have faith. It looks like private industry will point the gov't in the right direction as various renewable energy technologies continue to emerge. There is an important paradigm shift we all need to realize. There will no be no single dominant energy production source in the future. Just like computer networks, we will shift from 'mainframe' fossil fuel power plants to distributed 'PC' networks of local grid-tie power production. I see cars running on electricity and heavy equipment on biodiesel.
I also agree that Hydrogen does not make sense as a primary power source. The electricity required to perform water electrolysis is better used to run motors. However, Hydrogen reformers that extract Hydrogen from traditional fuels supposedly have lower overall Carbon emissions. In the future, we may have hybrid vehicles that run on electricity derived from Hydrogen fuel cells with the Hydrogen derived from oilgae from a Hydrogen reformer. This type of system may not be the most chemically efficient regarding total BTU in vs. BTU out. But it may have the lowest Carbon footprint.
