[Hidden-tech] Biodiesel

Very interesting discussion.

Biodiesel burns wicked clean.  Pricey though - $4.50/gallon. 

Used vegetable oil is free.  Disadvantages - you need to convert your
engine, so as to be able to preheat the oil, compared with biodiesel where
all you have to do to your diesel engine is replace fuel lines and gaskets.
The conversion kit is $800 - $1200, and if you have it installed that's
another $600 - $800.  The other disadvantage is you have to compete with the
biodiesel companies to stake out your source of used oil.

I love the idea of running on vegetable oil and plan to do it if I can ever
find a used diesel car I can afford.  Even better would be a car that would
run on garbage.  Probably wouldn't smell too good though.

Compared to regular diesel, B100 (100% biodiesel) generates FAR less
pollution:

unburned hydrocarbons (-67%)
Particulate matter (-47%)
CO (-48%)
Sulfur - the primary cause of acid rain (-100%)
Polycyclic Aromatics - the primary carcinogen found in petrochemical
emissions (-80-90%)

NOx emissions are 5-10% higher.

B100 is also extremely stable - it has a flash point some 150 degrees F
higher than regular diesel - safe enough for me to carry around a jug of it
in the back of my Beetle.  It also smells like cooking oil, which is
downright pleasant compared to the rotten-eggs-and-ester smell of
dino-diesel.

I'm ignorant of any comparisons to gasoline, but my feeling is that, like
ethanol, it's got to better: clean and renewable.  The premium price of
biodiesel will be less of a barrier as gas prices continue to increase.  I'm
already happy to pay extra.

In addition, in the Pioneer Valley area, a new biodiesel plant (that will
use waste veggie oil as the feedstock) is in the works [breaking ground this
spring/summer] in the Greenfield Industrial 
Park.  http://www.northeastbiodiesel.com   They will only be selling 
wholesale, but a cooperative group, CoopPower
(http://www.cooppower.coop) is a major investor and hope to maintain local
control of this sustainable energy resource.

Locally, you can get biodiesel blends at the pump in Greenfield and
Brattleboro (at the Flemoil Stations) and also in Holyoke (at Alliance
Energy).  Yellow BioDiesel is available in 5 gallon jugs in many stores and
service stations in the region as well.  http://www.yellowbiodiesel.com/

I have been successfully running my 1978 Mercedes Benz 300 sedan on
biodiesel for the last 6 months.  Runs great and I get the same
(poor) 27mpg as on petro-diesel.

Ebay, Greasecar classifieds, and Craigslist are all good options for finding
a diesel (in Mass).  In other states (and when the low-sulphur diesel
requirements go into effect in Sept), you can buy a new diesel car or truck.
Already 22% of VW sales are in the diesel segment:

hope this helps
