Topic: coffee to fuel cars (17 msgs / 320 lines)

http://www.goodcleantech.com/2008/12/coffee_to_fuel_cars_in_the_fut.phpCoffee to Fuel Cars in the Future
coffee_fuel.jpgI've always thought of coffee as a fuel, but admittedly not in
this context. As researched by scientists from Nevada, coffee could soon power
not just our sluggish brains during mornings, but also vehicles. The study
published in the American Chemical Society's (ACS) Journal of Agricultural and
Food Chemistry states that "spent" or used coffee grounds could be utilized as
feedstock for making biodiesel.
One of the problems that prevent biodiesel from taking off and becoming big is
the lack of cheap feedstock. Used or "spent" coffee grounds which are remains
from the production of espresso, java, or espresso, could apparently be a
cheaper, alternative feedstock for biodiesel. This is due to the fact that 11 to
20 percent of spent coffee grounds' weight is made up of oil. That's about the
same percentage of oil in the usual biodiesel feedstocks such as palm, peanut,
soybean and rapeseed.
To be able to test their theory, scientists collected spent coffee grounds and
then extracted the oil contents (the leftover solids could be used as compost or
as feedstock for ethanol). An inexpensive process was used to turn all of the
oil extracted into biodiesel that reportedly smelled like java, which is a plus
in my book. The coffee-crazed global populace warrants 16 billion pounds of
coffee to be produced per annum and, based on that figure, 340 million gallons
of coffee-based biodiesel could potentially be produced.

A little back-of-the-evelope tells me that equals about 1 days worth of US
oil demand.  Every little bit helps...

I might also suggest an olive oil biodiesel as a light lunch for your car or
a spicy Thai coconut oil biodiesel to invigorate an aging engine. =
Can you imagine collecting coffee grounds from all the little café shoppes
around? =

Hmm. On average I drink about a quart of brewed coffee each morning,
and my commute to work is 20 miles each way. I wonder how many miles
the grounds from 32oz worth of coffee would take me...

"...spicy Thai coconut oil"
?? I like coconut oil, which is pretty solid at our kitchen temperature.
Great with raisins, a dash of salt and a spritz of raw honey or brown sugar
in a bowl of oatmeal or porridge. In the Philippines and Thailand, it would
indeed be the liquid form.
Just like with coffee at the time, the button down palate couldn't
distinguish between coconut sources in the meat, milk or the oil taste.
Retorting rocks for the kerogen is a poor source of energy. Land Barge
pilots would do well to rethink their energy sources- how many million
barrels of crude oil will be replaced by a year's worth of the  whole
world's coffee grounds? What, then, are you going to do for tomorrow's crude
fix?

My late dad would be happy to know spent coffee grounds could provide an
alternate means of producing fuel. He spent many years (and probably
consumed lots of java in the process) pursuing alternate fuels including, of
all things, candy bars. Thanks to Baylor University and the Mars Candy Co.,
who contributed returned/recycled candy bars, enough alcohol was produced to
fuel a round the world flight by pilot Max Schauk. So don't think "it can't
be done!" -Bob Glasscock

"Hmm. On average I drink about a quart of brewed coffee each morning,

Let me see if I can noodle this out.  @ 1.5 grams / oz, you're probably
using 50 grams of coffee (give or take).  The article said coffee grounds
were up to 20% oil, so that's 10 grams of oil.  Let's assume it all becomes
fuel, so 10 grams of fuel.  1 gallon of diesel = 7.3 lbs (thank you Mr.
Google).  So that means you have 0.003 gallons of biodiesel.  Assuming your
deisel car gest 40 MPG, that's 0.1208 miles or 637 feet 10 inches...or there
abouts.

Or another way to put it: in order to achieve energy independence, I
would need to increase my coffee consumption to 662 press pots of
coffee per day, assuming I just go to and from work.
For this to become a reality, I think I'll need to switch to espresso.

You may achieve energy independence, but I'm guessing you'll spend most of
the day in the bathroom.

"The article said coffee grounds were up to 20% oil"
20% by weight or volume?
The article begs credulity. (...up to...) 0.02% is in that range. 20% would
make the grounds resemble black bean soup.
The well-known coffee chain regularly makes their spent coffee grounds
available to passers-by of their remaining outlets. As we know, they don't
roast the beans, they retort them, which should maximize oil production.
Ever strike oil when you hock your spent espresso pucks onto paper towels?
Of course, the oil was emulsified in the crema for a good shot. Why botch a
good shot to make maybe one pass with your Briggs and Stratton lawn mower?
The Specific Fuel Consumption for an Otto cycle, gas engine is about 7.44
lb/hp/hr, using gasoline with a heat content of 18917 BTU/ lb. Using 32 hp X
7.44 = time to do some gravitational experiments and inspect the backs of my
eyelids-

so if you took all the grounds from your local charbux could you gain 
energy independence?
