Algae really seems to be catching on as the new way of creating bio-diesel. I just met with a scientist the other day who has his own patents for converting algae to fuel.

Some algae are able to fix atmospheric nitrogen. See

I don’t know if the algae mentioned in this article are of that type.

Nitrogen can partly be obtained by using CO2 from a waste gas stream of a power plant. The waste gas contains NOx. It is important to find a way not to use petro chemical fertilizers, so there ar options in using waste water to provide N, P and K.

While it is clear algae obtain carbon from the carbon dioxide in the atmosphere, where are they obtaining nitrogen in a form suitable for synthesizing the protein that will be sold as feed?
