I had a 73 Chevelle with a 350, Doug Thorley headers and an aftermarket cam.
The BEST fuel economy in that machine was at about 40 miles per hour.  I find
your observations hard to believe.  Either your vacuum gauge wasn't working
properly (was it hooked up to manifold vacuum, or carburetor vacuum?), you had
very low gearing in that car (like 4.11s or worse!), or your memory is not
functioning at its peak.

I don't intend to insult you.  The fuel economy issue can be addressed with
mathematical formulas relating to mass, coefficient of drag and velocity.  I 
have
never witnessed an automobile that did not rigorously conform to the principles
of physics.

I don't know anything about formulas. All I know is what I have done. I 
drove a 1989 mustang with a 302. I got 31mpg at 65mph. I drove it at 110mph 
and got 27mpg. Thats only a 10% loss in milage.

Re: [biofuel] how much do you know

[Brent S]

There are more variables than the formula can account for. Tire size and 
gearing can make a difference on efficiency. Also type of fuel used can 
affect milage, along with aftermarket additives. My 1984 toyota van was 
getting very poor milage for a 4 cyl mini van. I reduced my rear tire size 
to bring up my rpms and increased milage over 20%. I then added a fuel 
additive and increased another 10%. The engine must run at it's peak to get 
peak milage, regardless of speed, run too slow and it lugs and over fuels, 
run too fast and you burn too much gas versus resistance on the vehicle.

The truck I have now already runs at 2200 rpm at over 60 mph. To increase 
the milage I would need to put smaller tires on the back to get the rpms 
back up to 2500-2750, which is the sweet spot for a chev 350 in a 3500 to 
4000 pound vehicle. Most trucks in those years would run 3000 rpm at the 
same speed. In that case I would increase tire size and put in a lock-up or 
overdrive transmission.
Every vehicle can be tweeked to be more eficient, but every vehicle is an 
individual case. I have had them all, small vehicles with big engines and 
stock ones and everything in between. I have my own formula. Wieght 
determines gearing and powertrain mods.

Power makes milage!!! I took a 1975 chev 3/4 ton truck with a 4V 350 that 
was getting 15mpg, which is normal for that type of truck, and increased the 
milage to 21 mpg at 60-65mph. I then put in a 262 V8 from a monza and got 
10mpg at the same spead.

I also test drove a ford festiva when they first came out. Against the wind 
it wouldn't do 60mph, and I imagine the milage would be poor too. It was too 
underpowered for anything more than a grocery getter in town.

[biofuels-biz] biocides

[Seth Mead]

Hello All-
I am the owner of a small business in upstate NY which converts diesel 
engines to burn straight vegetable oil.  We have recently gotten into 
large scale oil collection/filtration/distribution.  My question for 
the list is this.  Does anyone have any good ideas for workable 
biocides to mix with the filtered SVO?  We haven't experienced any 
growth yet but I would like to prevent it before sneaks up on us.
Thanks for your time.

All oils are "harmfull" to some extent or another, smothering

If you're choice is to not wash with straight base I don't know why

Methanol is only dangerous when not used properly. For what purpose 
would you  burn it if you intend to use a recovery system?

CH3OH + O2 + N2 will yield H2O, NOX (nitrogen oxides), CO2 and CO

[biofuel] San Francisco Adopts The Precautionary Principle

[Keith Addison]

http://www.rachel.org/bulletin/index.cfm?issue_ID=2338

Rachel's Environment & Health News #765
June 18, 2003

Environmental Research Foundation
P.O. Box 160, New Brunswick, N.J.  08903
Fax (732) 791-4603; E-mail: [EMAIL PROTECTED]
http://www.rachel.org

San Francisco Adopts The Precautionary Principle

The San Francisco Board of Supervisors adopted the precautionary 
principle as city and county policy June 17, 2003, a stunning and 
unprecedented breakthrough in the management of environmental matters 
in the U.S. The vote carried 8 to 2.

The long political road to the June 17 vote began when San Francisco 
mayor Willie Brown hired Jared Blumenfeld to head the city's 
Department of the Environment.[1] Under Blumenfeld's guidance, San 
Francisco government spent more than 2 years studying and debating 
how to integrate the precautionary principle into city- and 
county-wide policy. It was Blumenfeld who corraled the political 
resources to put precaution on the agenda in San Francisco.

But the dream of a city guided by the precautionary principle 
originated with a breast cancer activist -- Joan Reinhardt Reiss of 
the Breast Cancer Fund (San Francisco). At least three years ago, she 
phoned Carolyn Raffensperger of the Science and Environmental Health 
Network (Ames, Iowa), the leading proponent of precautionary thinking 
in the U.S. Reiss also contacted attorney Sanford Lewis (Waverly, 
Mass.), who drafted preliminary language for an ordinance. Seeds were 
planted.

Early on, Katie Silberman of the Center for Environmental Health 
(Oakland) joined Reiss in the drive for precaution in San Francisco. 
In 2001, Reiss and Silberman introduced Raffensperger to Blumenfeld. 
Wheels began turning. Reiss and Silberman were joined by Davis Baltz 
of Commonweal (Bolinas and Oakland). Together they developed the Bay 
Area Precautionary Principle Working Group.[2]

Other key actors were Randall Hayes and Francesca Vietor. Hayes, the 
founder of Rainforest Action Network, is now a member of Commission 
on the Environment for the City and County of San Francisco. He 
headed up an ad hoc committee on the precautionary principle for the 
Commission. Vietor used to hold the job now held by Blumenfeld, 
directing the San Francisco Department of the Environment. She now 
works for Commonweal, which is run by Michael Lerner and Sharyle 
Patton. Vietor used her political skills and knowledge to keep things 
moving.

Gary Erickson, founder of Clif Bar (http://www.clifbar.com), 
organized a business breakfast at the San Francisco Foundation to 
catalyze business interest in precaution. It worked. Many small 
businesses in San Francisco came to support the emerging 
precautionary policy. It helped that Frank Ackerman and Rachel Massey 
at Tufts University had written their report titled "Prospering With 
Precaution," showing that precautionary policies create jobs and are 
profitable for business.[3] The work of other precaution activists in 
Massachusetts -- notably Lee Kettelson and Joel Tickner -- was 
instrumental as well.

While Jared Blumenfeld was working inside San Francisco government to 
develop precautionary policies, the Bay Area Working Group built a 
coalition of non-governmental organizations (NGOs) to support and 
critique the language developed by Blumenfeld and his colleagues. The 
San Francisco White Paper on Precaution is one of the best statements 
of the principle available today.[4]

Both the NGOs and San Francisco government called upon the Science 
and Environmental Health Network (http://www.sehn.org) frequently for 
strategic thinking, language, and support. SEHN staff Nancy Myers, 
Ted Schettler, and Carolyn Raffensperger put in countless hours 
helping San Francisco achieve its goal.

But in the end it was a combined grass-roots victory. Some of the 
NGOs involved included (in alphabetical order),

Bayview Hunters Point Community Advocates (San Francisco), Breast 
Cancer Action (San Francisco), The Breast Cancer Fund (San 
Francisco), Center for Environmental Health (Oakland), Citizens for a 
Better Environment (CBE, San Francisco), Clean Water Action (San 
Francisco), Commonweal (Bolinas and Oakland), Consumer Action (San 
Francisco), Environmental Research Foundation (New Brunswick, N.J.), 
Green Action (San Francisco), Physicians for Social Responsibility 
(San Francisco and Los Angeles chapters), Redefining Progress 
(Oakland), The San Francisco Foundation, Science and Environmental 
Health Network (Ames, Iowa), Urban Habitat (Oakland), and The Women's 
Cancer Resource Center (Oakland).

As you read through this policy, ask yourself, would my local work be 
easier if precaution were official policy in my community?  Why not 
campaign to make it so?

[biofuel] Faster = More Gas = More Energy.

[DAVEINBHAM]

John said"  Faster = More Gas.  More Gas = More Energy. "
Maybe yes, maybe no. 
It depends on what you are driving as well as how fast you are driving it.
As a good rule of thumb, driving at torque peak for your engine in top gear 
usually comes pretty close to the best MPG you will be able to get. 
Remember, when you put your foot closer to the firewall, you are really only 
increasing the air the engine gets, not the gas ( in MOST, but not all cases). 
The onboard " computer" then determines how much gas the engine needs for the 
amount of air your foot is metering to the engine. If your car is old enough 
to have a carburator just remember it is the mechanical ( or vaccum) "program" 
that feeds the gas to the engine.
The best way to determine the highway speed for best MPG is to ask the 
manufacturer of your car. The answer may suprise you.

Kindest regards,
Dave

Going ones are, I guess. It'd be a can closer rather than a can 
opener. But any heavyish vehicle would do - sounds as though Mike 
might have some such available, if they've collected that many cans 
in the first place.

The last bit explains why you don't use the glyc to clean the cans!

Question: what sort of burner are you using? And is the glyc your 
only source of processing heat? I presume that's unseparated glyc: 
glycerine + soap + catalyst. Methanol reclaimed?

[biofuel] Re: how much do you know

[Forbes Bagatelle-Black]

Air resistance goes up dramatically as a function of speed, per the 
following equation:

Power = 0.5*Cd*FA*V^3

where
Power is the power consumed by the vehicle
Cd is the drag coefficient of the vehicle
FA is the frontal area of the vehicle
V is the speed of the vehicle

Using this equation, you can see that it takes more than twice as much 
power for the same vehicle to go 70mph as it does to go 55mph (2.06 
times as much power).  Energy is power * time, so differences in 
energy usage will not be quite as dramatic as differences in 
instantaneous power usage, but they will not be very far off.

Of course efficiency plays a major role in the equation also.  
Engineers can design a drivetrain to be most efficient at whatever 
speed they choose, but most of the time that V^3 term overwhelms any 
efficiency differences.

Respectfully

Re: [biofuel] bio-heating oil?

[Andreas W Ohnsorge]

Michael,

I tried to mix in my central heating WVO with diesel-oil in a conventional
burner for diesel-oil. It did work quite well under following conditions:

  - no more then about 30% of WVO
  - Filter the WVO before use to about <50 micron (this is the normal
filter for diesel in most cases for burners !!not for motors!!)
  - Heat the WVO to about 50 - 60 degrees Celsius (usually this is also
the max. temp limit for the high pressure pump)
  - take care that the flame gets longer and produces more grime
because the drop size of the WVO is bigger and the drops
 won't burn that good.

I answered already to another question on burners the following:


Interesting to hear that vegoil burners are still on the market - my
experience although is that these companies either do not want to sell them
(I was told by a burner company here in Germany that the quality of the oil
is so different from charge to charge that they had lots of problems with
these installations) or they are very expensive (about 2 - 4 time as
expensive as a standard burner). What I tried during the last couple of
weeks (so SOME experience, but not too much yet) is the following:

Basis of my thoughts: The "problem" with vegoil is the high boiling point
and the high viscosity compared with light diesel / oil. To overcome the
viscosity issue it is very easy to do the same as the vegoil car-drivers
do: heat it up (I did this by using part of the central heating water and I
heat the filter unit which has a 50 micron filter in it).

The second issue is more difficult because you need either a burner that is
built for heavy / medium oil instead of light (unfortunatelly those burners
are usually only available for 50kw + power) or use one that vaporizes the
oil and burns the vapor afterwards. This type of burners is called "rocket
burner", a special type that is usually used to burn light diesel-oil
without grime (info on the following url:
http://www.la.dlr.de/en/ra/Heizbrenner/Raketenbrenner.html).

To really make it working properly I had to modify the start sequence in
the following way:

  - The burner starts on conventional oil for some seconds to heat up
the vaporizer
  - The vegoil is added to the filter by a used industrial dose-pump
  - To stop the burner the burner the system is flushed at the end of
the phase for 1 minute with diesel-oil

This seems to work fine and I can share my experience with enyone
interested...


Hope it helps...

This would be true, I guess, all other things being equal.  There is increased
wind resistance at higher speeds.

A car will generally get better mileage in highway driving, not because higher
speeds take less energy, but I guess because the city cycle involves throwing
much more of it away.  Stop-and-go of city driving means that as you slow down a
lot, you are throwing away energy.  Also, as you accelerate, you use more than
just the small bit of energy needed to supplement coasting to keep up to a fixed
speed?

One car on the market I think got higher mileage in city tests, which was the
Toyota Prius.  This was, I think, because it was able to recycle more energy in
simulated city stop-and-go, whereas at less-break-usage highway driving, it was
not as able to do so.  In other words: regen brakes, depending on how it's set
up.

Hello all,

Yes, we are working in supercritical conditios. This is, very strong
conditios for the oil and methanol. There is no space for "kitchen"
experimentation. We have change ALL the design for this kind of
reactors, in one way that, they are very safety. One of this reactors
can be broken near from someone, and nothing will happen. I will give
you an example. The pressure and temperature, inside of a diesel
engine combustion chamber, it«s higher than the pressure and
temperature, inside of our reactor. However the diesel engines are
very safety because they are designed to run on this conditions (if
not, maybe this engines can gone be very dangerous). I can give you
thousand examples, like planes, cars, etc., we just have to do well
designed machines. For me, the safety is FIRST, because I will
operate my own pilot plant in some months.
I«m sorry I can«t give you more details.
Best wishes,

Mauro Knudsen.

[biofuel] Re: Reusing washing water

[appalenergy]

Magnesium sulfate (epsom salt) works. Even plain sodium chloride 
(table salt) will work to some degree.

Warning! Overkill on salt will produce an even worse problem, as 
saline effluent can yield a dead zone just as readily as soap 
accumulation.

Re: [biofuel] re: Kerry Energy Plan

[Hakan]

Kuchini do not specify an Energy policy, but if you read the
issues related to it, like environment, foreign policies etc.,
he does not stand out from the rest of the bunch. When I
got the question what I thought about him, it was like I missed
something. He did not make a difference, I am still waiting
for something real. The fact that he want to join Kyoto, make
the use of coal less possible, but I think that he would adjust
this stance on Kyoto if he get elected.

I do think that Kuchini try to stand for a highly isolationistic
policy, but it was a long time ago that US had that option. It
is however dangerous and counter productive for US to even
try it.

Kerry is at least honest enough to talk about coal, which
means Hydrogen ("City gas" as in eastern Europe) and synthetic
fuels from coal, which is also the key element in the Bush plan.

All of them are talking about Solar and Wind, easy and appealing
to the public. The only short term leverage to find, is a key element
of biofuels and real energy conservation actions. All of them are
talking about "Natural Gas" and all except Greenspan and the market
price are totally unreal on this. R/P values for "Natural (fossil) Gas"
are worse than for oil. This apart from a lack of transportation and
terminal capacity as Greenspan pointed out.

Re: [biofuel] Iceland: >70% Renewable, Wants H2 Power

[Hakan]

It is only two countries in the world that have this situation, Iceland
and New Zealand. The reason why it is interesting, is the possibility
of plentiful and cheap electricity generated by the geysers. They need
to convert this to fuel and Hydrogen is a good solution.

[David Teal]

Also in UK, have had the same problem.  Tried angle grinder (eats blades and
VERY noisy), jigsaw better but still somewhat antisocial, and a nibbler
which is great, although it creates thousands of small crescent-shaped
shards of tinplate swarf.  To get the nibbler started, a sharp chisel makes
the initial hole.  The discs go to metal recycling, while the barrels are
flattened out and used to clad over the insulation of the various hot bits
of my biod production plant.  Best way to clean the old oil off is firstly
heat to allow it to flow away and then hot water & caustic soda (you will
already have some of this anyway).
btw, my heat nowadays comes from burning glycerol.

Re: [biofuel] re: Kerry Energy Plan

[murdoch]

His page is apparently here:
http://www.kucinich.net/

I just started hearing about him a week or two ago.  If you look to the left
under "issues", I do not see Energy Policy listed explicitly.Under More issues,
there are a couple of related topics, but nothing stands out.

Kerry's campaign page is here (as opposed to his Senate page): 
http://www.johnkerry.com/site/PageServer

Without getting into a giant debate about all the candidates on all the issues,
I think a point here for me is that Kerry makes Energy Policy discussion one of
his top priorities at almost every opportunity.  This allows us to know his
views on the Energy Policy issues and debate them.  Every candidate has their
major issues that they chooose to focus upon, and Energy Policy is one of
Kerry's.  I'm not sure which other candidates are into that particular issue.

Yep, true but can openers are a wee bit cheaper than even the most second

[biofuel] Iceland: >70% Renewable, Wants H2 Power

[murdoch]

I cannot understand why it is so all-fired important for the precise fuel to be
Hydrogen, and only Hydrogen.  Here we have an entire country which has an
interesting project going, but they run up against the same old thing:

Hydrogen is not that easy to store and transport (at present), partly because it
is a gas at room-temperatures and well-below.

Why not try various types of simple liquid Hydrocarbons as a de facto means of
storing and transporting the hydrogen?  I don't know much about it, but it seems
that some of them (i.e. methanol, etc.) can be reformed and used in fuel cells.
So, what's the big deal?  Instead of making just plain H2, why not try making
methanol, ethanol, and the like, and then, once they're at the point of use,
reform them and use them in your high-efficiency low-emission fuel cell?  Even
if some efficiency was lost, it would be a welcome way to address such matters
as fuel-for-vessels.

I think such a method is not perceived as a method of transporting and storing
Hydrogen atoms, and I guess one could argue that it's just using a different
fuel.  But who cares?  The idea is not to so heavy-handedly pre-determine, that
there is only one valid fuel choice in a sustainable effort, but to explore all
possible choices.

Another problem is that I think some folks are not that bright, and need to
focus on Hydrogen because of the simplicity of the idea.

To be sure, making H2 and keeping it in its basic form may present certain
advantages over the alternatives I've suggested.  But those alternatives are not
even mentioned or discussed in these huge efforts, it seems.

Re: [biofuel] Biogas technologies

[Keith Addison]

Hello Eong and Pannirselvam

Could you provide a description of the technologies you're using?

I'd welcome more discussion of biogas issues and technologies - we do 
have it, but not enough, IMO. Very much on-topic here. Recent 
discussion on the composition of "natural gas" (LPG) and other 
sources of methane came close.

We've discussed these before, among others - bag digesters:

http://www.ias.unu.edu/proceedings/icibs/ibs/info/ecuador/install-polydig.htm
How to install a polyethylene biogas plant

http://www.fao.org/WAICENT/FAOINFO/AGRICULT/AGA/AGAP/FRG/Recycle/biodi 
g/manual.htm
Biodigester installation manual

Are your units similar?

Re locally available raw materials, I wonder what could be adpated to 
serve the purpose of a polyethylene bag... When you see something 
like this it seems anything's possible!

Re: [biofuels-biz] New to biofuels and a quick question

[Len Walde]

HI:

For the right tool you have to go to the right place!  Look up restaurant
equipment business's. Many of them sell large can openers -- manually
operated, for opening restaurant sized food ingredient cans. These work for
opening/ removing the top from,  five gallon veg. oil cans.  I have done it.
I bought one, used, a few years ago for about $35.00 U.S.

Good luck.

Re: [biofuel] Reusing washing water

Hello Tomas

I don't know how you handle the wash process, but if you do multiple 
washes you can reuse water from later washes for earlier washes of 
the next batch. See Marks' Bubblewashing 101 for details:

I remember your talking about this some time ago, I was wondering how 
you progressed with it. Be interested to hear some more details. 
Quite a lot of folks talk about using a greywater system, though I 
don't know of anyone actually doing it - you'd be the closest, and 
maybe better than greywater.

I hope someone else will be able to tell you that.

Hello Mike

Our local incinerator (yuk - it's a high-tech job but yuk just the 
same) collects them for packing junked batteries in for return to the 
recyclers. Dunno what the battery recyclers do with the cans.

Why do you have to cut the lids off first? Can't you just crush them 
lids and all? Run over them with a Land Rover or something - that'll 
flatten corrugated iron, should work on a partly flattened can.

Best

[biofuels-biz] New to biofuels and a quick question

[Mike Cox]

hi there,
 
i'm relatively new to the biofuels scene and have just got involved in a small 
project in the uk.
 
An issue which has come up is disposal of 5 gallon vegetable oil drums.  We 
have rapidly collected a very large number of these and are trying to determine 
the best way to recycle/reuse these drums.
 
One idea was to use some kind of tin opener to remove the lid section, and then 
crush the can flat for storage and subsequent recycling of the metal.  Is this 
a sensible approach?  Can anyone recommend a suitable device for opening these 
drums?
 
Alternatively does a system exist for the collection and reuse of these drums?
 
thanks for your assistance
 
Mike

Re: [biofuel] Fuel efficiency vs Speed

[Darryl McMahon]

My interests in electric and human powered vehicles have led me to do some 
research 
in this area.

Aerodynamic drag increases with the square of velocity, and proportionally with 
frontal area and co-efficient of drag (Cd).

The energy required to overcome aerodynamic drag increases with the *cube* of 
velocity.   IMHO, this is the important fact.

Aero drag is not the only factor.  There is also rolling resistance and drive 
line 
losses, which typically are constant or rise very slowly with velocity (e.g. 
tire 
hysteresis, bearing friction, brake drag etc).

In a conventional road vehicle, rolling resistance usually dominates the losses 
from 0 to 40 km/h.  From 40 to 60 km/h, depending on the vehicle, aero losses 
and 
rolling losses are usually comparable.  Above 60 km/h, aero losses typically 
dominate.  This is what the theory would indicate, and has been borne out in my 
experience with bikes, Electrathon vehicles and on-road electrics (where we 
have 
very precise measurement of power consumption in instantaneous amps and volts, 
and 
watt-hours over given distances).  

In my electric Fiero, which is relatively aerodynamic for a road-car, the most 
efficient speed appears to be about 65 km/h, based on instantaneous amperage 
readings.  Above that, the aero effects become appreciable.  Interestingly, 
having 
the headlights up or down makes about a 5% difference in energy consumption at 
speeds around 65-70 km/h.

The 55 mph speed limit of the 70's and 80's in the U.S. were a compromise 
between 
the science (that would tend to favour speeds around 45 mph for simple 
efficiency / 
fuel economy), and what Americans would tolerate in their permanent state of 
hurry. 
 Also, at the time, there was a dramatic difference in fatality statistics for 
collisions where speed limits were 55 mph or lower vs 70 mph.  (Remember "Speed 
Kills" posters?)

In our (long-gone) New Yorker, notable only for its fuel usage computer, we 
could 
see the difference between 90 and 110 km/h cruising as being about 18% (8 
liters/100 km at 90 km/h vs 9.5 liters/100 km at 110 km/h).  Government of 
Canada 
figures (Drive$mart program) have long stated that it takes about 20% more 
energy 
to cover the same distance at a constant 110 km/h than at 90 km/h. (67 vs 55 
mph)

A similar conservation gain can be achieved by ensuring all tires are up to 
proper 
inflation.  Under-inflated tires can reduce fuel economy by up to 5% per tire, 
shorten tire life, and contribute to poor handling.  Slightly over-inflated 
tires 
will improve fuel economy slightly, but can impact handling due to reduced 
contact 
patch (between tire and road).  A misfiring cylinder can also reduce fuel 
economy 
by 10% or more, so keeping your engine in good running order also improves fuel 
economy.

You may be thinking of ethanol, which forms an
azeotrope with water. Methanol does not, meaning
that it IS possible to achieve 100% by (fractional)
distillation alone. However, simple distillation will
carry over a portion of the water present, tho always
less in the vapor than in the liquid below. I would
recommend molecular sieve rather than CaO to remove
the residual water from the methanol, if for some
reason you can't construct an adequate fractionating
column. -K

Re: [biofuel] Reusing washing water

[mark schofield]

Dear Tomas

The very same problem I have had. Soapy water and
lots of it. OK, I have experimented by adding
phosphoric acid so that the final pH is of order
1.75. The soap in part cracks back into FFA or
the insoluble portion floats to the top quite
quickly. I think last time I added around 1cc of
85% acid to 500cc used wash soap water and that
seemed to partially remove the soap ie back into
FFA and scum. 

Industrially, a process called Electroflotation
is used. Its very simple and I am making one
using the core from a 150A 20V AC welder
rectified and smoothed. The idea is to place
aluminium and steel plates into the waste water.
The aluminium is at -V and the steel at +V. A
galvanic couple is established and the aluminium
dissolves over time. H2 and O2 gas are given off
respectively and inconjunction with the ions
transfered into the water (namely H+) the stream
is neutralised over time and the solid particles
flocculated ie floated as scum to the top. A
10GPM industrial unit can be bought for £40k GBP
or a very basic DIY one made for about £200 I
have spent maximum so far.

Tell me what you think.

Mark

[biofuel] Methanol Dehydration CaO

[mark schofield]

Hi,

Just a passing thought. Vacuum recovered methanol
at 50mBar boils at around 15-20'C. The water
content ought to be quite low but methanol forms
an azeotrope with water. Therefore, if the
recovered methanol were mixed with CaO (quick
lime) to remove the water content the soap
producing element ie water plus Na+ ions and FFA,
could be reduced.

Has anyone ever thought of using Avation grade
Fullers Earth filters to remove the caustic
surfactants from bio-diesel?

Secretary Wants International Partners for Hydrogen Economy

U.S. Secretary of Energy Spencer Abraham has called on the European
Commission (EC) to join the United States in forming what he called
The International Partnership for the Hydrogen Economy. The Secretary
issued the challenge Friday during his keynote to the EC's Conference
of the High Level Group on Hydrogen and Fuel Cell (HLG-HFC)
Technologies convening in Brussels. In 2002,HLG-HFC Technologies--a
coalition of EC auto and transport companies, utilities research
institutes, and policy makers--made advances in hydrogen a top
priority. At the same time, U.S. President George Bush established the
Hydrogen Fuel Initiative to develop hydrogen infrastructure and
hydrogen fuel cell-powered vehicles and introduced the Freedom CAR
program to develop automotive systems that use hydrogen fuel.

In his address the Secretary said an international partnership that
includes devotion of substantial financial resources would make
hydrogen power a viable energy source much more quickly, and told the
conference, "We believe our work on hydrogen and the work being done
elsewhere around the world is perhaps the most significant game-
changing endeavor the energy sector will see in our lifetime."

See the DOE press release on the Secretary's remarks:



DOE Asks Eaton to Advance Hybrid Truck Systems

DOE will give $3.1 million over three years to Galesburg, Michigan-
based Eaton's Truck Components to develop hybrid propulsion systems
for trucks and other heavy duty vehicles. Hybrid propulsion systems
generally consist of smaller internal combustion engines augmented by
an electric drive, a power storage system, and regenerative braking or
other energy recapture systems. Today, most heavy vehicles use diesel.
Eaton will invest an additional $4 million in the three-year project
aimed at doubling the fuel efficiency of truck engines while at the
same time increasing reliability and durability of components and
meeting lower 2007 federal emissions standards.
See the DOE press release:



University of Wisconsin Wins FutureTruck 2003

For the second straight year, the University of Wisconsin, Madison
placed first in DOE and Ford Motor Company's FutureTruck competitions,
scoring 841 of 1,000 possible points. DOE's Assistant Secretary David
Garman presented the team with a check for $6,000. For other award
winners and results see the FutureTruck site:



Illinois Passes Biodiesel Tax Incentive and Grants Package

Illinois Governor Rod Blagojevich signed legislation last week that
will provide a partial state sales tax exemption of 20 percent on
biodiesel blends containing from one to ten percent biodiesel. The
legislative package also established the Illinois Renewable Fuels
Development Program, which offers grants up to $15 million annually
for constructing, modifying, altering, or retrofitting a renewable
fuels plant with a minimum production capacity of 30 million gallons.

According to the Illinois Soybean Association, the legislation will
add five cents per bushel to the price of Illinois soybeans. Illinois
produces 450 million bushels of soybeans per year.
See the press release on the National Biodiesel Board Web site:


Southern states are also developing more biodiesel projects, according
to Southern States Power, a minority owner of Delta Green Power, LLC,
which announced last week that the company is purchasing three two-
megawatt biodiesel fuel generators to provide electricity and thermal
energy to industrial clients in the Delta region of Mississippi. See
the Southern States Power press release:

Secretary Wants International Partners for Hydrogen Economy

U.S. Secretary of Energy Spencer Abraham has called on the European
Commission (EC) to join the United States in forming what he called
The International Partnership for the Hydrogen Economy. The Secretary
issued the challenge Friday during his keynote to the EC's Conference
of the High Level Group on Hydrogen and Fuel Cell (HLG-HFC)
Technologies convening in Brussels. In 2002,HLG-HFC Technologies--a
coalition of EC auto and transport companies, utilities research
institutes, and policy makers--made advances in hydrogen a top
priority. At the same time, U.S. President George Bush established the
Hydrogen Fuel Initiative to develop hydrogen infrastructure and
hydrogen fuel cell-powered vehicles and introduced the Freedom CAR
program to develop automotive systems that use hydrogen fuel.

In his address the Secretary said an international partnership that
includes devotion of substantial financial resources would make
hydrogen power a viable energy source much more quickly, and told the
conference, "We believe our work on hydrogen and the work being done
elsewhere around the world is perhaps the most significant game-
changing endeavor the energy sector will see in our lifetime."

See the DOE press release on the Secretary's remarks:



DOE Asks Eaton to Advance Hybrid Truck Systems

DOE will give $3.1 million over three years to Galesburg, Michigan-
based Eaton's Truck Components to develop hybrid propulsion systems
for trucks and other heavy duty vehicles. Hybrid propulsion systems
generally consist of smaller internal combustion engines augmented by
an electric drive, a power storage system, and regenerative braking or
other energy recapture systems. Today, most heavy vehicles use diesel.
Eaton will invest an additional $4 million in the three-year project
aimed at doubling the fuel efficiency of truck engines while at the
same time increasing reliability and durability of components and
meeting lower 2007 federal emissions standards.
See the DOE press release:



University of Wisconsin Wins FutureTruck 2003

For the second straight year, the University of Wisconsin, Madison
placed first in DOE and Ford Motor Company's FutureTruck competitions,
scoring 841 of 1,000 possible points. DOE's Assistant Secretary David
Garman presented the team with a check for $6,000. For other award
winners and results see the FutureTruck site:



Illinois Passes Biodiesel Tax Incentive and Grants Package

Illinois Governor Rod Blagojevich signed legislation last week that
will provide a partial state sales tax exemption of 20 percent on
biodiesel blends containing from one to ten percent biodiesel. The
legislative package also established the Illinois Renewable Fuels
Development Program, which offers grants up to $15 million annually
for constructing, modifying, altering, or retrofitting a renewable
fuels plant with a minimum production capacity of 30 million gallons.

According to the Illinois Soybean Association, the legislation will
add five cents per bushel to the price of Illinois soybeans. Illinois
produces 450 million bushels of soybeans per year.
See the press release on the National Biodiesel Board Web site:


Southern states are also developing more biodiesel projects, according
to Southern States Power, a minority owner of Delta Green Power, LLC,
which announced last week that the company is purchasing three two-
megawatt biodiesel fuel generators to provide electricity and thermal
energy to industrial clients in the Delta region of Mississippi. See
the Southern States Power press release:

Re: [biofuel] Riello burner non-information

[Andreas W Ohnsorge]

Interesting to hear that vegoil burners are still on the market - my
experience although is that these companies either do not want to sell them
(I was told by a burner company here in Germany that the quality of the oil
is so different from charge to charge that they had lots of problems with
these installations) or they are very expensive (about 2 - 4 time as
expensive as a standard burner). What I tried during the last couple of
weeks (so SOME experience, but not too much yet) is the following:

Basis of my thoughts: The "problem" with vegoil is the high boiling point
and the high viscosity compared with light diesel / oil. To overcome the
viscosity issue it is very easy to do the same as the vegoil car-drivers
do: heat it up (I did this by using part of the central heating water and I
heat the filter unit which has a 50 micron filter in it).

The second issue is more difficult because you need either a burner that is
built for heavy / medium oil instead of light (unfortunatelly those burners
are usually only available for 50kw + power) or use one that vaporizes the
oil and burns the vapor afterwards. This type of burners is called "rocket
burner", a special type that is usually used to burn light diesel-oil
without grime (info on the following url:
http://www.la.dlr.de/en/ra/Heizbrenner/Raketenbrenner.html).

To really make it working properly I had to modify the start sequence in
the following way:

  - The burner starts on conventional oil for some seconds to heat up
the vaporizer
  - The vegoil is added to the filter by a used industrial dose-pump
  - To stop the burner the burner the system is flushed at the end of
the phase for 1 minute with diesel-oil

This seems to work fine and I can share my experience with enyone
interested...

Damian,

If my memory is right, Riello is an Italian manufacturer of burners for
heating equipments. The have biodiesel burners available in Europe,
but it seems that it is not generally available in US (politics).

No!
Too simple, you have forgotton about gears.  With a standard it is really 
noticable, my foot postition in 5th is much higher than in first, when I am 
getting the vehicle moving.
Bright Blessings,

[biofuel] Reusing washing water

[Johnsson Tomas]

Hello List,
 
Do some one have experience or ideas of how the washing water could be
cleaned from soap, methanol and other particels for to be reused as washing
water in the process (closed washing water system) . 
The particles are easy to remove by settling the water during the settling
also the methanol can be vented from the water. But how can the soap be
removed from the water?  How do the water treatment plants remove soaps from
the water (flogging)? We have experinced with filtering the washing water
through a torff, humus, sand bed this seams to bind the soap in the torff
and clean water then passing through the other layers. The torff can then be
composted when enought soap is binded. We have also made some tests with
adding som Phosphoracid to the washing water. The acid formed a layer of
white stuff on the surface of the washing water. What is the white stuff
floating on top of the washing water? Is it a phosphate?   
 
Any ideas, help on the road or is this not possible?
 
Tomas

[biofuel] Useful Chart from TDIClub

[Tim Castleman]

Many thanks to Aaron for sending this link to a discussion going on in the
TDIClub forum about MPG @ MPH.

http://forums.tdiclub.com/showflat.php?Cat=&Board=UBB16&Number=517408&page=0&view=collapsed&sb=5&o=14&fpart=1

I have reproduced chart from that forum that shows the dramatic decrease in
MPG as MPH go up and placed it on the www.drive55.org website. To summarize,
in TDI's the highest MPG is at 35-40MPH, and it decreases substantially as
speed increases.

I also found a site for Honda Insight owners where they post their actual
experiences and brag about getting the highest mileage on trips, very much
like the race idea that has been discussed here lately. Here is a link to
that site:

http://www.insightcentral.net/owners/trips.html

Again, it really does come down to a compromise between standing still and
movement. Of course we could use no energy by not going anywhere, and I
confess the idea is appealing, but not very practical.

A Mile-A-Minute seems plenty fast to me.

A US family of 5 can save over $2,500 per year by simply slowing down! ( See
"Funding Petroleum Warlords" in the archive or at www.drive55.org )

Disarm the Petroleum Warlords, Drive 55, its the next best thing to making
your own fuel.
