Chile's Sky becomes latest airline to enter into biofuel pact

They're coming thick and fast now, these airline/algae biofuel producer pacts.

Check out the latest one between Chile's Sky Airline and Florida-based renewable energy company PetroAlgae.

British Airways got in on the act earlier this year when it teamed up with the UK's Cranfield University on a project to push forward the use of algae in the production of alternative fuels for the airline industry.
