Many people have suggested using flue gas, but it is not necessary.  (It
will increase growth, but is not required.)

The projections based on lab results are many times higher - even better
yields.

I'm confused - I thought brackish meant between seawater and freshwater.
Partially treated sewage would be vile, but not salty.  Or, did I miss
something?   Some people have suggested doing a methane digestion on the
sewage (animal or human) in order to kill pathogens.



One complication is that the algae require sunlight to convert the

Greenfuels reported some mitigation even in darkness, so it might not be
necessary to store overnight.

Are any of these species heavy producers of oil?

We assume we will have to do something to break the cell wall.

A group of us are trying to understand all the steps in this process and
develop an open-source process for growing oil from algae.  You are invited

Lots of research done in the past.
