Many of these alternative fuel concepts are great stories, and I think that one important thing to remember is that we don’t currently have the infrastructure for a environmentally friendly energy industry. As such you will find many arguments against alternative resources citing valid scientific research that shows these methods to be more harmful to the environment. Let’s not forget the laws of Supply and Demand – basically, if we continue on the right path of building demand for environmentally friendly energy than these arguments will work themselves out because the money that is behind all large scale developments (which will never be made to care about the environment) will care about very much about wasted opportunity and will naturally gravitate to the least wasteful resource.

for instance, anonymous said: “What the article didn’t say was that burning the biodiesel would release the CO2 that had been ’sequestered’ in the algae. No so green after all!”

This is true, but because of the basic laws of economics, this CO2 that is released by burning biodiesel will soon be a valued resource instead of harmful waste, and there are already companies in place working on the technology to do so… I’m thinking of a small Whelsh team that patented a product recently which they called “Greenbox” I believe… but I’m sure that there are more.

I read a story in the media recently about a company that wants to sequester CO2 by connecting coal-fired power plants (for example) to an algae farm. The algae would absorb the CO2 as they grow. So far so green.

Then the article went on to say that the algae would be used as a source of biodiesel. Wow! This just keeps getting better, doesn’t it?

What the article didn’t say was that burning the biodiesel would release the CO2 that had been ‘sequestered’ in the algae. No so green after all!
