In a brief conversation with Harrison Dillon, President and CEO of Solazyme, I was able to learn that Solazyme is going to combine cellulosic ethanol and algae biodiesel production technology, which they think provides a more positive energy balance than either one alone. Solazyme will be buying sugar, including cellulosically-derived sugar produced by cellulosic ethanol companies, to feed to their algae. They’re basically short-circuiting the cellulosic ethanol process and diverting the sugar to what they say is a more efficient process: growing micro-algae.

Not as Green as it Sounds
Hi,
Were you aware that the Green Party in Britain (and elsewhere in Europe) is opposing the widespread use of biodiesel/ethanol as a solution to the transportation issue?
The issues at stake have to do the vast mono-culture farming techniques that such a transition would involve. This has already started in parts of Africa and Latin America with millions of acres already being used for soya, sugar and rapeseed at the expense of sustainable food production for local communities. Land grabs are already underway with evictions of subsistence farmers increasing.
The long-term result of these trends is likely to be a reduction in the availability of locally produced foods in parts of the developing world, a corresponding increase in food prices both there and in developed countries and a degradation in soil quality (which is typical in mono-culture situations).
Meanwhile, airlines and car manufacturers are falling over themselves to develop these "greener" technologies despite the growing number of qualified voices raising concern over the rush towards ethanol.
This may prove to be a false dawn as far as genuine environmental progress is concerned.

I agree, leave the food on the table where it belongs. However, I disagree that biofuels are not still a viable alternative to fossil fuels. I don't see anyone eating algae! Valcent Products www.valcent.net, has data showing that 33,000 gallons of biodiesel can be produced and refined on 1 acre of nonproductive land. In the United States, 6,000 square miles of arid land can produce enough biodiesel fuel to totally replace fossil fuels, sustainably, year after year. There are zero carbon emissions as the biofuel is used to generate electricity to run an all electric nation. The carbon emissions are recycled back into a close loop system to increase the production of more algae, along with the sun, and small amounts of mostly recycled water. Naysayers pushing fossil fuel, are the real fossils.
We have the land
I am never surprised at any organization in the UK (a place that would probably fit in a corner of Texas) being all aflutter about land use. And while I agree that the developing world (or the financial creeps that "invest" in the developing world) are making very bad decisions that adversely impact the local people and the global climate, attacking land use in the USA as a cause of starvation or climate degradation is disengious at best, We have the land to spare to create a lot of biofuel without extreme harm to food production. Even the corn (which is an attrocious choice for biofuel production) is not as big a factor as the detractors try to make it. We had freak weather that flooded the midwest and that was our major cause of corn shortage. Bottom line is that as we in the US use land APPROPRIATELY to make fuel we reduce the prices of global energy and make the less favorable land use less profitable. We are __**STOPPING**__ the conversions in other countries. Economics is as it is. The USA has an abolute advantage in biofuels creation.
