Right, but it also says this:
"Biodiesel can be distributed using today's infrastructure, and its use and production are increasing rapidly. Fuel stations are beginning to make biodiesel available to consumers, and a growing number of transport fleets use it as an additive in their fuel. Biodiesel is generally more expensive to purchase than petroleum diesel but this differential may diminish due to economies of scale, the rising cost of petroleum and government tax subsidies."
And I think the wastewater article is pretty good too:
"A New Zealand-based company has become the first to manufacture home-grown bio-diesel using algae extracted from a sewerage pond – an innovation that could have implications for the global bio-science sector.
"We believe this is the world's first commercial production of bio-diesel from algae outside the laboratory, in 'wild' conditions," proclaimed Barrie Leay, spokesperson for Aquaflow Bionomic Corporation, achievers of the milestone.
Algae converts sunlight and carbon dioxide into energy through photosynthesis, in the same way plants do. Excess algae in ponds can smell, since they extract all the nutrients, hence the so-called bio-remediation of stagnant ponds not only cleans water but also provides the sustainable element of environmentally friendly fuel."
This would be great here, the cost of water treatment has driven up water bills in metro Boston to $1600.00 a year!(Thnx G.H. Bush for making the dirty harbor a campaign issue:furious ) It would be nice if some of the costs were offset from the sale of biodiesel.
