Replying to: bristol2 (Apr 06, 2007 7:34 am) I am wondering what scientific or environmental qualifications a panel of 44 auto journalists might have that gives the award any significant meaning. I think a similar panel gave the 1960 Corvair an award for being the most inovative. |

Replying to: blufz1 (Apr 14, 2007 12:54 pm) Apparently terrorism is a valid subject for this site as it has been mentioned so many times by so many posters. As we speak there are demonstration in Mexico against the rising price of corn meal. American farmers are planting more "Bio corn" and less food corn because the price is better and likely to be more predictable, and the crops are easier to grow. Note that currently it is used primarily to produce ethanol for gas vehicles. Other types of crops could be substituted, but any reliance on crop land for fuel means less crop land available for food production, however marginal. With 16,000 children in the world starving to death everyday (Recent UN estimate) do any of us begin to feel like terrorists in our reliance on any automobile that depends on agriculture to sustain itself? Doesn't it seem that at some point severe legal restrictions will be placed on the automobile including diesel, and the unmentionable other car words? As for making US farmers rich through framing for bio fuels: the vast majority of farming is done by US corporations, not US farmers.

Question for the HOST: Will a discussion of Mercedes' tentative plans for a BLUETEC/"Unamable" S-Class be allowed here, or is it off topic?

But for discussions sake, I wonder if an analysis of the comparitive size and weight of the vehicles might indicate that the European vehicle fleet is on average newer, smaller, and lighter than the American fleet and that that contributes very significantly to increased average fuel economy?

Replying to: hypnosis44 (Apr 14, 2007 1:19 pm) Scientists believe carbon dioxide is one of the main greenhouse gases contributing to global warming. Neat biodiesel (100% biodiesel) reduces carbon dioxide emissions by more than 75% over petroleum diesel. Using a blend of 20% biodiesel reduces carbon dioxide emissions by 15%. Biodiesel also produces fewer particulate matter, carbon monoxide, and sulfur dioxide emissions (all air pollutants under the Clean Air Act). Since biodiesel can be used in conventional diesel engines, the renewable fuel can directly replace petroleum products; reducing the country's dependence on imported oil. Biodiesel offers safety benefits over petroleum diesel because it is much less combustible, with a flash point greater than 150°C, compared to 77°C for petroleum diesel. It is safe to handle, store, and transport. http://www.eere.energy.gov/afdc/altfuel/bio_benefits.html

Replying to: gagrice (Apr 14, 2007 5:46 pm) After several hours of searching and weeding I located this as well - you may already have it. http://en.wikipedia.org/wiki/Biodiesel I am also searching for current similar environmental comparisons of gas to petroleum diesel - not to be debated here, but for my own elucidation.
