Successfully creating algae industry
Economic Boon --- Higher Standard of Living --- Massive Job Creation

in US is greater than
800 million mt/year
An Algae Industry Would
Solve the Protein Crisis

FAO projections
Trigger Unrest
• Need 3x aquaculture protein ONR/AFOSR
Study
• Need 2x other protein
• Crop yield increase ~1.2 %/year

An Algae Industry Would Contribute to
Global Environmental Solutions
Global Agricultural Footprint
Leading cause of deforestation and
Land 1,000 acres of algae
habitat loss is for protein production
Mass
saves 40,000 acres
Water Leading cause of global water
Use
impairment is agricultural run-off
Accounts for 24% of global greenhouse
GHG
gas emissions
Emissions
Algae has no run-off,
prevents dead zones

Presents Multidisciplinary Problems with
Multiple Breakthroughs Required
‘Show-stoppers’
• CO supply
2
• Water use
• Mixing energy
• Harvesting energy
• Weed algae & predators
• Open system productivity
• Scalability
We seem to have a few problems going
from lab-scale to full-scale production
Demonstrated Solutions to
All ‘Show-Stoppers’
Cultivation System
Avoids contamination
CO supply 100x greater scaling
2
24-hr capture ¼ mixing energy
2.5” water press. drop 3x productivity
Long-term storage Rain capture
200x less control pts
No ground-level
flue gas release
