Food for thought on Bush and alternative fuels

Don't forget that a large part of polution produced by pure biodiesel or the biodiesel part of B20 was absorbed by the oil producing plant a few months/year earlier, so it is cycling the polutants from air to solid to liquid and back to air, not adding what was essentially stored for millions of years in oil deposits.

I went to this site

http://www.fueleconomy.gov/feg/bymake/bymanuNF.shtml

and compared gasoline VS diesel engines of the same year in the same vehicle with the same transmission and found that consistantly the diesel engines without much polution controll (late 80's early '90s) and with mechanical injection (could be most closely related to a carbureted gasoline due to the non closed loop aspect) emited lower anual green house gasses than their gasoline brethern with electronic closed loop fuel injection, catalytic converters and extensive polution controlls.
Now I fastforwarded to 2002 VW since it is the only mainstream diesel availible in the states curently, 1.9L diesel emits 20% less greenhouse gas than 2.0l gasoline, and when compared to the larger gasoline engines the difference is even greater.

With the advances in computer controlled diesel engines particulate mater has been drastically reduced in stock power plants, sadly not in some overly modified vehicles though

Probably, it isn't the only solution, more people using mass transit would be great, but in the sparcely populated areas out here ridership would be inadequate to support it a 15 minute drive across town would take almost 2 hours by bus so what is the point of saving a couple dollars to ride the bus? I looked into building a little electric car to drive arround town, but it would be so expensive to build that by the time it half way paid for its self I would need new batteries.

I'd love to see a hybrid diesel electric that could get 100+mpg

I just found this solution for nitrogen oxides

My problem is that even if the FPM output standard is down to .2 and being reached... what happenes when there is 20-30 fold vehicles puting out .2 and for more hours in the day???? It'll still be a huge step back. My buddie's 1.9l biogolf (an 03) never ran as clean as my 97 2.2l subaru. I have cali heads on it though if that really matters and his was auto, mine is 5 speed.

As I said before I like the idea of b20 becoming a replacement fuel (even up to 70) used in trucks and buses (with the appropriate controls and equipment, most importantly forced air) but I really do not want to see it becoming the replacment for gasoline. I'd much rather see more hybrids and eventually electrics and so on.

Notice what happens when people start getting out for the day...
With b20 used as a large consumer fuel those greens will start becoming yellow or orange, and those yellows will start becoming orange or red...

missed that post, yeah, I'm aware of that. Once again, trucks and buses.
