Yes but the art will be in turning the problem into a resource!

Presumably "lumen" is just a gross quantity of light, it tells you
nothing about the spectrum? 

One of the vague memories I have from looking at renewable energy in
the 70s was that one of the problems with chlorophyll was that its
ability to make use of light saturated at insolation greater than
200W/m2. The thing about an algal pond was that as the algal
chloroplasts were in constant motion they could make better use of the
light as their average exposure was reduced to this level even in
direct sunlight which was exceeding 1kW/m2. Again from old memory I
think this meant a 1.5% energy yield could be obtained when
agriculture was managing only about 0.75% at that time.

Has any commercial algal production made human or animal food
commercially yet?

OK we see many posts talking this up, with wood pellet production now
almost all mopped up in the west it may well be the way to go,
generally arable systems have much lower harvesting costs than
forestry.

Yes, reed, again we see posts from Americans suggesting cattails as a
resource, this is similar and I think what we call bulrushes.

Again these are used here to act as final filters in water treatments
and for the plants to make use of the phosphorus and potassium from
the sewage.

Willow grown as arable short rotation coppice has not been much of a
success yet in UK and typical yields have only been ~7tonnes/ha/annum
which is only 2/3 of what was expected.

I think you are referring to Japanese Knotweed, a highly invasive
plant that it is illegal to transport in UK!
