I know very little about this stuff currently, glad you bring these points up actually. So I don't know how to quantify this, how much extra land does it take to reliably dry out the algae from a given amount of land? And how much extra energy does it provide? Presumably it would yield more energy than just growing more algae on that land.

I didn't see any obvious sources for that data, do you have a link? I mean wvo, sure, but I don't know anything about pre-consumer foods. The other side of the coin is that biodiesel still has to come up with some ethanol and deal with some glycerine and left over biomass and further drying.

Definitely an improvement over petrol. You are basically solar powered at that point, with the performance and initial cost of an ice.
