[Bioconversion] The Pond Scum Fireball

[Mr Robert Marmaduke]

Jeff:

You're on a good track! Serpentine ponds with 
paddle wheels would move the young algae float
through the ponds into dense matts, where they
could be harvested and air dried for tilapia
feed, with a portion of the algae returned to 
the head of the ponds to re-seed them. 

The tilapia can be harvested and sold for $5
a pound as organic white fish. Heavy demand.
Wild MidWest fish are mercury-contaminated.

If you're in a corn-growing region, where the
corn can be fermented into ethanol, which is
growing by leaps and bounds for Clean Air biofuel.

The ethanol can be sold by 29,000 gallon tankcar 
lots for $2 a gallon. Heavy demand.

The additional algae and tilapia entrails can 
be mixed with spent mash cake as a protein-
supplemented cattle feed.

The cattle can be harvested and sold for $5
a pound as organic beef. Heavy demand.

The cattle manure could be anaerobically 
digested for methane to power generators  
to light the ponds, and to circulate them
to increase algae and tilapia production. 

The stabilized manure would then fertilize
the algae ponds for increased production,
also can be used to fertilize the corn crop.
That and tilapia water itself can be routed into
a greenhouse and used to grow organic tomatoes 
at $5 a pound. Heavy demand.

The manure solids and corn bagass can be 
dried and used as hog-fuel to supplement-
heat the tilapia ponds and greenhouse,
along with the methane-powered lights.

They grow tilapia and tomatoes up in Canada.

End products of this 4W recycling concept:

Ethanol at $2/GAL
Organic Tilapia at $5/LB
Organic Beef at $5/LB
Organic Hothouse Tomatoes at $5/LB

Anywhere in the MidWest that grows corn,
has flowing water, and is within truck-
farming strike of a metropolitan market.

Now you're talking some serious green!
