Algae biofuels.

This morning in the news on ABC Australia it was reported that Virgin has used biofuels during a test flight. This of course brings all the reactive responses from people that don't know what they are talking about.
I would just like to point out that there are biofuels that won't use arable land or 'steal food from Africans" and all that other dosh that people come up with. These fuels are called algae biofuels and not only do they not use productive or marginal land but they actually use waste products from industry.
There is an engineering movement that is trying to create Zero Emissions from industry, so people can still have their gadgets and all the mod cons but create less pollution in the production of these goods.
Algae photo bioreactors (APB's) use waste products from factories to feed algae, which is then processed fairly easily into an effective fuel. It is still being researched, but there are APB's up and running in many places.
http://www.apbe.com.au/science.html will give you a bit of background on these marvellous machines.

Perhaps people who spend their time reacting against positive news for the environment should spend that time actually looking into what can be done to help reduce our negative impacts on this little planet of ours.
There are many small things that can be done which will add up to a good thing.
