Hype and more hypeHype and more hype
Algae can produce up to 15 times more oil per acre than all other plants used for biofuel
Algae can double its volume overnightIt would take an algae farm the size of
Texas to produce enough hydrogen to meet the world’s energy needs

The ProcessThe Process
Ultrasonic waves are used to create cavitation bubbles in a solvent material
When the bubbles collapse near cell walls they create shock waves and liquid jets that cause the cell walls to break and the oil to be released into the solvent

Algae as Fuel: Biological Hydrogen
Algae as Fuel: Biological Hydrogen
C. reinhardtii, when deprived of sulfur, will switch from producing oxygen to produce hydrogen.
Due to an enzyme within called hydrogenase, which is activated when algae’s internal oxygen flow is interrupted.
