"Here I might point out that some of the more vociferous algae pimps are
suggesting that algae need merely be introduced into a properly designed,
water filled bioreactor and the organisms will multiply until the unit is
packed to overflowing with tons upon tons of green biomass, all in the space
of days. This is patent nonsense."
and
"Algae cannot fix nitrogen from the atmosphere, and so they require some form
of nitrogenous fertilizer, whether synthetic or natural. That might be
provided by landfill organic wastes or agricultural residues of various sorts
or specially prepared nutrient compounds, but whatever the source, you're not
getting tons and tons of living biomass unless you put in tons and tons of
decomposed biomass. It's just like any other kind of farming. You get out
what you put in."
My own initial reaction is this. Are the people now living in the
southwestern states going to sit idlely by while their water gets diverted to
grow algea?
