[Gasification] Gasification and Water Injection into producergas

[Peter Wilson]

It's been successfully trialled on a sewage pond in Blenheim, New Zealand.
According to the company involved, its the first time its been achieved in a
'wild' environment with a normal species of algae, ie, no laboratory magic.
Biodiesel from algae solves one of the major problems associated with it as
a fuel - the ecological footprint of growing the biomass to make the fuel.
