I did calculations a year ago, which showed that point to be at 2,820 gal. http://algae-thermodynamics.blogspot.com/2007/11/cash-burn-vs-algae-diesel.html With their new funding that figure ought to be above 4,000 gal now. At the same time the 100 sq.m. farm that they are building now would only produce 130 gal/yr. They need to go to around 3,000 sq.m and to operate it for a full year before getting to the point where the money would no longer have been spent better by literally burning it.
