In a forest of tubes eight metres high in eastern Spain scientists hope they have found the fuel of tomorrow: bio-oil produced with algae mixed with carbon dioxide from a factory.
Almost 400 of the green tubes, filled with millions of microscopic algae, cover a plain near the city of Alicante, next to a cement works from which the C02 is captured and transported via a pipeline to the "blue petroleum" factory.

The other great advantage of the system is that it is a depollutant -- it absorbs the C02 which would otherwise be released into the atmosphere.
"It's ecological oil," said the founder and chairman of BFS, French engineer Bernard Stroiazzo-Mougin, who worked in oil fields in the Middle East before coming to Spain.

I have to say I am a bit leery of any type of oil being a depollutant and "ecological" however, if that is the case, this could be something to watch.
