Microalgae is a highly efficient feedstock for producing biofuels that is more sustainable than using food crops. It can grow in non-arable land and water and recycles carbon dioxide from waste sources. While algae has been grown commercially for decades, producing cost-competitive biofuels from algae is challenging. However, Kai BioEnergy has developed an open pond production system that has significantly lower operating and capital costs than other methods, making algae-derived biofuels economically viable. Their process also has synergies with waste-to-energy systems through carbon dioxide recycling and use of algae biomass.

6. Economically Viable Algae has been grown for decades – as feedstock for aquaculture and for health food supplements like Spirulina, Dunaliella, Chlorella, but can biofuels be economically viable? 100 Yen per capsule ($4,000 per Kg) Needs to be < $2 per gallon ($1 per Kg)

7. KAI is Economically Viable KAI's proven, highly efficient, and fully integrated open production system has a 40X operating and 10X capital cost advantage 1x 40x $1.32 $53.12 Operating Costs ($ per gallon) 1x 10x $40.5K $405.7K Capital Costs ($ per acre) Others Kai BioEnergy

8. Waste-to-Energy Synergy Synergistic Relationship with Waste-to-Energy Deployment: Waste-to-Energy CO2 emissions used to grow algae, and after lipids are extracted algae biomass fed to back to Waste-to-Energy

9. Not all Algae is Good Potentially toxic Blue-Green-Algae is becoming a world-wide issue

10. Environmental Applications A technology that can remediate blue-green-algae issues, and has many other environmental beneficial applications

11. New Wind Technologies New technologies make deployment in Tahiti a reality: much smaller, more power, lower cost, better materials, 2-250 mph range! Wind Community Farms with 150 Kw -800 Kw Turbines Large Scale 1+ Mw Turbines Old, limiting technology
