.....that some of the diesels running in London, GB are very old technology and they did not get on the bandwagon until the last few years. Biodiesel may help them, but keep in mind that some of the "STUDIES" are there for one reason to justify the existence of the so called researchers. Researchers who push a political agenda to satisfy the politicians who want a predetermined outcome.
Another item to take into consideration in London is the extensive use of coal over the years and the fact that coal dust and soot hangs around forever until it is cleaned up, this may be a contributing factor to Black Lung type problems. My wife and I own a house that we rent for now that was built in 1888 and for many years was heated with coal. I did some plumbing updates in a part of the house that has a crawl space and just the required pounding and sawing from that put coal dust throughout the house that had to be scrubbed up, even in the closed up cupboards in the dining room.
The coal furnaces of the past in homes both here and in Great Britain were not as clean as the coal power plants in use even those with 70 year old technology. Most of the newer power plants and upgraded existing power plants use a process that gets as much as it can out of the coal with minimal amounts of soot. Scrubbers on the coal fired plants remove stuff from the exhaust using lime which is later used on farm fields. Minerals such as sulfur and selenium which are bad in the air are good in the soil and produce healthier crops with less commercial supplements and fertilizers.

Good point. Based on what I’ve read, it appears that the use of diesels in America are going to increase dramatically. I read DieselPower magazine (which I feel is a reliable source of information) and they are reporting that many auto manufacturer are now moving towards more diesel applications. Future technology is leaning towards a diesel/electric hybrid, which might be the key to keep diesel technology and diesel interest in the forefront. I’m hoping that algae diesel will reach it’s expectations and be the healthy alternative to dino.
