I am a bit confused by the comment of Dean Tsoupels. Tsoupels states that the algae are fed sugars, nutrients and carbon dioxide. I see nothing in the press release or the video of the press conference that would indicate that carbon dioxide is consumed in the formation of algae as in a photo-biochemical reactor.

This is similar to the method being developed by Solazyme, growing algae in tanks in the dark, feeding them sugars instead of in sunlight. A major factor is that the algae does Not need to be exposed to light. Just feed it sugars, waste nutrients and CO2. This does Not take up farmland. And it is highly concentrated production - 10,000 to 20,000 gallons of fuel per acre per year, with a potential for up to 100 tons of Algae biomass per acre per year or more. Growing algae in the dark on sugar, you can stack algae tanks as high as you want. Or stack them underground, 100 feet deep. Put a parking lot over the top of that. Stack them also around corn ethanol refineries, and grow algae on the waste CO2, nutrient rich effluent, and waste heat. This is in the works. Algae is not just about oil. After the oil is extracted, you have proteins that can be made into feed and food. And, you have starches that can be made into ethanol, an industry that is presently over 10 times bigger than biodiesel. Algae protein byproducts create an excellent revenue stream as commercial fish feed, such as farm raised tilapia, salmon, and others. Another aspect of growing algae commercially, is its value as a human fool supplement. Chlorella is currently valued at $18 a pound retail. Chlorella and spiralina for human nutritional food supplements are already a multi-billion dollar international industry. Biodiesel, ethanol, animal feed and human supplements – these are all intertwined. To be produced at the same facility by the same company(s). No more biodisel vs ethanol dogma. No more food vs fuel dogma. We are going to get it all out of Algae. Overall, my point is, we have to get over this obsession with algae oil. The byproducts are just as important, in terms of the full exploitation and profitability of algae.
