Yeah, but better this than destroying potential food or arable land.
Yes, if it works. Its selling point seems to be that with typical algae, you first have to squeeze out its vegetable oil, then mix it with lye and ethanol, then strain it to get biodiesel. But somehow their algae generates biodiesel directly, without poisoning itself, and in a concentrated enough form that it is easy to separate from the water.
I guess.
