Nice links and photos. I presume the 3rd photo is an artist rendering? Anyway, read National Geographic's article on the potential for algae ethanol and was impressed by how much more fuel could potentially be produced over a year's time. It was 3,000 gallons for corn ethanol, and as much as 50,000 gallons for algae ethanol, due in great part to the speed at which algae grows year round. Most people are not aware that the oil we use is the result of millions of years of compression and heat applied to dead algae. As the oceans stagnated algae filled them, then sank to the bottom, the ocean life died due to a lack of oxygen and soil filled over those layers, techtonic plates slipped and moved and eventually all that algae ended up as oil in two distinct layers in the crust, dating back from two eras 90 and 150 million years ago.
So it would seem that if oil can be mass produced as a viable form of ethanol, our best bet is to find ways to scale up algae ethanol production. We flew back from Oklahoma to California via an airline that flew too slow and too low, but what I realized from the view was just how many empty valleys there are in Arizona, Utah and Nevada that could be used to make ethanol.
I think the process of using CO2 enriched air as a way to capture it from Coal should not be requisite to make algae ethanol. It would seem that if plain old simple air is pumped fast enough the CO2 will get converted and we should have lots of fuel, but I'm not certain of that - please illuminate me. As a result, as an investor, I have been keeping my eye on Greenfuel Tech., waiting for that right company to invest in. My understanding is Verasun has a stake in Greenfuel, so if it does take off they may be a good bet. Right now I'm taking a wait and see approach. But certainly one to watch.
The window frame of opportunity to catch the world economy before it dumps in catastrope, by way of a scaled up mass produced fuel, is still open but we must move fast. Otherwise at some threshold of price for energy the world economy will stagnate, then price of energy and economic activity will balance/stalemate at some tepid level not conducive to well being of 6.5 billion people.
Addition to my prior post: That is 3,000 gallons per acre for corn versus 50,000 gallons per acre for algae ethanol.
Corn yields perhaps 2.8 gal/bu and averages ~150 bu/acre, so you're going to see around 420 gal/acre. Anyone claiming 3000 gallons from corn is smoking something.
Credible algae claims are in the region of 5000 to 10000 gal/ac. Even 2000 would be pretty darn good for a cheap process.
I'm probably stating the obvious or asking a stupid question, but...
Corn is a solid, is it not? So you ned to add the liquid, do you not? If making ethanol is anything like brewing drinking alcohol, then you need sugar, water, yeast. So wouldn't making ethanol have an impact on the water supply?
I'm sure it takes far more water to grow the corn than to process it, but the issue of contamination from wastewater can't be ignored.

That is for oone crop. Maybe some areas can have 3 crops a year, assuming 350 bushsls/acre and 3gal/bu, that would work. But it seems to be a stretch.
BTW, How much biomass is in the cobs and stalks, compared to corn kernels?
To me it seems that there is more potential in processing the "waste".
What strain of maize can come to maturity in 120 days at that yield? With enormous amounts of water, phosphate and nitrate I suppose you can do anything, but algae seem cheaper.
Around half (maybe more if cobs are included, I haven't checked lately). A bushel of corn is 56 pounds, so 150 bu/ac is 4.2 tons. The Corn Stover Collection Project found roughly 2 tons/acre of harvestable stover, after allowing for erosion control.
