                             Overview
•   Algae promises a sustainable and scalable solution to production of a
    variety of materials. Particular strains of algae are being investigated for the
    production of biodiesel, ethanol, and cellulose.

•   Using cellulose as a raw material it is possible to produce large amounts of
    lactic acid in a fermentation process. The lactic acid can be polymerized to
    form poly-lactic acid (PLA) which is a biopolymer that has amazing
    properties. One of these properties is that it is compatible with extrusion
    technologies and can be effectively "printed" using apparatus featured on
    RepRap.org.

•   Since the ocean is a perfect breeding ground for algae it can be harnessed
    to produce copious amounts of cellulose in the near future. This raw
    material can be effectively converted into a construction material that can
    be formed into any shape desired - including floating ocean infrastructure.

•   By growing, processing and using the algae to produce the capability to
    grow, process and produce more algae the initial investment to create a
    system like this can be mitigated over time. This dramatically reduces the
    cost of moving existing infrastructure out into an ocean location. This is
    an efficient approach to ocean colonization.
        WhyAlgae andPLA?
• Algae
  – Biological superstar
  – Hardy, fast growing, flexible
  – Thousands of strains producing variety of
    resources
• PLA
  – Sustainable
  – Recyclable
  – Diverse applications
      PLAby NatureWorks LLC
• Branded as Ingeo™
  biopolymer, the resin is ideal
  for packaging manufacturing.
  Applications using Ingeo™
  biopolymer can be clear,
  opaque, flexible or rigid.
  Ingeo™ biopolymer provides
  gloss and clarity similar to
  polystyrene, and exhibits
  tensile strength and modulus
  comparable to hydrocarbon-
  based thermoplastics.
• Ingeo™ biopolymers are
  already proving themselves in
  a success in commercial
  applications currently using
  polyester, polyolefins,
  polystyrene and cellulosics.

                  Economicsof Production:
                                                    Estimates
•   Algae production rate = 10g / m2 / day in non-industrial greenhouse
    setting
    (source: La Capitelle Microfarm in Spirulina)

•   Max 50% by dry weight, average 20% cellulose content = 2g / m2 / day
    cellulose
    (Chlorophyceae algae)

•   Fermentation efficiency = 80-90 % = Conservatively, 1.6g / m2 / day
    lactic acid
    (with Lactobacillus delbrueckiii bacteria)

• Polymerization efficiency = 80% = 1.28g / m2 / day PLA final
  product
    (using dichloromethane at room temperature for 24 h)

•   Printing efficiency = 95% with any waste from final finishing of parts =
    1.1g / m2 / day
    (from RepRap.org)

• Rounding down to be conservative is 1g usable material / m2 / day
  production
• With a square kilometer production area that is 1 metric ton of raw
  materials per day

           PossibleApplication
• Create resort along
  the path of an existing
  cruise line and offer it
  as an extra stop and
  departure location
  similar to Catalina
  Island
• This way the cruise
  line can sell an
  additional night for
  little added cost
• Also a deal may be

  made to re-supply the      7 Night Mexican Riviera Cruise

           Economicsof Production:
                   Costs
•   Construction of closed system so that the strain of algae is not diluted
    by wild-type organisms
•   Production of algae including robotic agitators to expose more algae to
    sunlight
•   Collection of algae (robotic harvesters possibly powered by solar or
    cyclone engine)
•   Processing of algae to lyse cells and expose cellulose to other organisms
•   Fermentation equipment, heating, separation, agitation, pH control,
    etc…
•   Polymerization reagents, equipment, and transport apparatus
•   Post-production processing to draw out polymer to required form for
    use in printing
•   Printing apparatus
•   Electricity for heating and extruder movement
•   Final finishing and assembly
