Have you checked the viscosity of FFA (take oleic acid as an example)?
The stuff I've made felt like about 28 centistokes :-) Thinner than oil
to be sure, but not thin enough.

Re: [Biofuel] uses for charcoal -- (was) simple cook stoves

[Pannir P.V]

Helo  Mike  , Dean Thomas  and Steve 


The  process  of making   or activating carbon   can be  simple  
chemical treatments  to remove the inorganic metal  using acids , 
steam  oxidation of organic  materials  or  ethanol  solvent removal
of  oganic materials.
  By using appropriate   filter media and support  the  Lye  formation
can  eliminated and hence no need to bother as  Steve thinking , as 
solvent  can form lye surely.

   Steve ,  the poor   really drink lye, water with impurities in
several part of the rural areas of the worldand what we want to  
do is to filter the lye  using  activated carbon

   I am not able to find the results about  ethanol solvent activation
as this is novel  and new process.
   Here  Keith can  come out  with the  recent work in this fields
from the   data banks , even though I have tried  to do so with out
success.
 For rural area  this  simple process is more favourable l than  
industrial  conventional methods  .

I am planning a trip (search and see) around the
states but I would rather not support our car culture.
I am an avid cyclist but for time, I'd like to find
some happy medium. So IF i can find people around the
country that would be willing to share there
experiences and maybe become a stop on what might
become a route for travelers.

I don't have it yet, but I would like to have a web
site that list all the stations, homes, farms, etc.
they can stop at and fill up. (without supporting
the...)

anything would help

Re: [Biofuel] cell phones and safety

[steve]

It is indeed important to maintain perspective.  Personally, I don't like
to see people drive and talk on the phone at the same time -- it's a
visible sign of a disregard for their own safety and the safety of others
on the road.  But if you review the statistics and studies on the NHTSA
(National Highway Traffic Safety Administration) website, it's plain to
see that talking on a cell phone isn't the holy grail of driving abuse
that some make it out to be.  For example, the NHTSA estimates that driver
distraction from ALL sources contributes to 25 percent of all
police-reported traffic crashes.  They do say that cell phone usage can
present a significant cognitive distraction, but the study also admits
that cell phone usage may be no more of a distraction than talking to
someone else in the vehicle.  Furthermore, in a controlled study,
comparing eating and operating a cell phone to continuously operating a CD
player, it was found that the CD player operation was more distracting
than the other activities.  In a test track study conducted by NHTSA, the
results showed that manual dialing was about as distracting as
grooming/eating, but less distracting than reading or changing CDs.

This leads me to wonder, despite my great dislike for drivers who yap on
the phone while driving, if cell phone usage isn't the real culprit --
it's the drivers themselves.  Some people are prone to distraction, and if
it wasn't a cell phone they might be daydreaming, or flipping the radio
around, or chatting with someone else in the car.  What we might have to
consider is that people may be at fault, not cell phones, and while
banning cell phone usage while driving may placate the public screaming
for action, it may also be that those same people who would distract
themselves using a cell phone may find something else to take its place.

[Biofuel] UK people's favorite invention

[MH]

 Two wheels good: Why Britain has
 fallen in love with the bicycle
 By Cahal Milmo
 06 May 2005
 http://news.independent.co.uk/uk/transport/story.jsp?story=635984 

 "Professor Heinz Wolff, emeritus professor of bio-engineering
 at Brunel University, in west London, who was responsible for
 nominating the bicycle, defended his choice."

 He said: "The provision of affordable personal transport which
 then became the motorbike, the motor car and the aeroplane ...
 changed humanity by allowing us to do something which was
 otherwise difficult or restricted to people who ... could
 afford a coach."
 --- 

 Bicycle chosen as best invention 
 The humble bicycle has won a UK national
 survey of people's favourite inventions. 
 5 May, 2005
 http://www.energybulletin.net/5952.html
 http://news.bbc.co.uk/1/hi/technology/4513929.stm 

 Listeners to BBC Radio 4's You and Yours programme
 were invited to vote in an online poll looking at
 the most significant innovations since 1800. 

 It was an easy victory for the bicycle
 which won more than half of the vote. 

 The transistor came second with 8% of the vote,
 and the electro-magnetic induction ring - the
 means to harness electricity - came third. 

 Interplanetary travel 

 Despite their ubiquity, computers gained just
 6% of the vote and the internet trailed behind
 with only 4% of all votes cast. There were
 more than 4,500 votes cast in total. 

 People chose the bicycle for its simplicity of
 design, universal use, and because it is an
 ecologically sound means of transport. 

 The survey also asked participants which
 innovation they would most like to disinvent. 

 GM foods came top of this poll with
 26% of the vote, followed by
 nuclear power with 19%. 

 By contrast, the technology most would like
 to see invented was an Aids vaccine. 

 Alas, plans to ship long-suffering commuters to
 distant planets may need to be put on hold with
 only 15% voting for an interplanetary commuting
 transport system. 

 Half voted water treatment and supply systems
 as the technology to bring most benefit to society. 

 Another 23% thought that vaccinations deserved the honour. 

 Each of the technologies were nominated by a different
 expert, including writer Sir Arthur C Clarke,
 cloning expert Professor Ian Wilmut, and
 Professor Heinz Wolff. 

 Prof Wolff's praise of the bicycle held the
 most sway with voters which will come as a
 disappointment to Lord Alec Broers, this
 year's Reith lecturer. 

 His series of lectures
 - Triumph of Technology -
 prompted the vote. 

 In the first of his talks, he expressed
 surprise at the results of a similar survey. 

 It too ranked the bicycle above scientific
 breakthroughs such as electricity generation,
 the jet engine, the discovery of DNA and
 the invention of vaccinations. 

 ~~~ Editorial Notes ~~~

 Most of our technology is dependent on cheap energy,
 at the very least in its manufacturing. Compared to
 'nature' there is almost nothing we can hold up
 favourably in comparison in terms of energy efficiency.
 The bicycle is the exception. It allows a human to
 travel with more energy efficiency than any other
 land animal. 

 Of course one must consider the embodied energy of
 the bicycle and road maintenance. Nevertheless,
 from an energy perspective the bicycle may yet prove
 to be the high point of human technological achievement!

 The Triumph of Technology
 BBC Radio 4
 You and Yours 
 http://www.bbc.co.uk/radio4/youandyours/technology_launch.shtml 

 To coincide with this year's Reith Lectures,
 entitled the Triumph of Technology, You and Yours
 asked what has been the most significant
 technological innovation since 1800.

 From the hundreds of listeners' nominations and
 together with our five experts, voting was
 opened on a final 10.  Here are the results...

 59.4% - Bicycle
 7.8% - Transistor
 7.8% - Electro-magnetic induction ring
 6.3% - Computer
 4.6% - Germ theory of infection
 4.5% - Radio
 4.0% - Internet
 3.4% - Internal Combustion Engine
 1.1% - Nuclear Power
 1.1% - Communications satellite

Re: [Biofuel] cell phones and safety

[Brian Thomas]

few years ago.  About 80% were caused by distractions outside the car 
(billboards, that woman walking down the street, etc.).  Of the 20% caused 
by distractions inside the car, the top two were eating in the car and 
adjusting the car stereo.  Cell phones were responsible for just over 10% 
the number of accidents caused by eating while driving.  If we're enacting 
laws, lets start with McDonald's drive-thrus and car stereos.

 I continue to be amazed by the disregard for others demonstrated by

 Talking on the phone take more attention than having a conversation

FFA's.  In small quantities it wont hurt anything in large quantities it 
will hurt something.  In the netherlands your primary problem is 
probably that FFA's will drive up you jell point on you wont be able to 
start your car on a cold morning.


If you knew how much phosphoric you used you could guess *at the FFA 
content of your fuel *of FFA's your running on.  If you acid treated the 
glycerin and knew how much FFA's you got out of that you'd have another 
guess the FFA content of your fuel.

Alltogether it was 1000 liters. Now I decided to try to break the soap with
phosphoric acit (75%) and let it sit for several weeks. The soap was cracked
and I was lucky to siphon from the top just over 700 liters of BD. I have
been driving on it, without any problems.
Maybe someone out there can do something with this information.
I have been thinking that I might be driving on FFA's at the moment in stead
of BD, but it works.

RE: [Biofuel] Biomass-to-Ethanol

[John Freeman]

This could be very exciting news.  A few questions:

Are we willing and able to harness genetically modified E Coli to do this?
What is the environmental risk of creating and distributing this organism?
Is it something that could be used at a small-farm scale, or only at a large
plant?

1 billion tons of "farm wastes", sustainably produced - really?  Are they
"wastes", or do we have to decide between composting the material back into
the soil, or turning it into fuel?  If fuel, are we taking yet another
billion tons of organic material out of the system?  Nice to see the
sustainability analysis. 

The header to this article says "replace half of all imported petroleum".
So if we (USA)import about 60% of 21 million barrels/day, let's say they are
talking about replacing 6 million barrels a day, or 2.2 billion barrels a
year, or 92 billion gallons a year.  The ethanol energy equivalent of this
would be more like 150 billion gallons - is it reasonable to get 150 gallons
of ethanol from a ton of crop waste using this (or any!) process?  Another
way to look at it - ethanol weighs 6.6 pounds/gallon, so 150 billion gallons
weighs 990 billion pounds or 500 million tons - so 50% by weight of the
input material must be converted into ethanol - darn good!

A few lines into the article it says "replace 1/2 of all automotive fuel", I
suspect that might be a different number than "1/2 of all imports".

people's lives, both good and bad, are felt by the people around them. Like a 
drop of water into a pool, everyone is effected and the waves never stop, they 
just get smaller with time and distance.

Activated Carbon used for water treatment I think is usually aluminum
silicate activated.

I'm afraid not.  The charcoal used in filtration is "activated charcoal",
which is made by burning bone or similar material in an oxygen-deprived
environment.  If you try to filter water through charcoal briquettes or
wood, I believe the output is LYE.  You could make soap with the lye I
suppose, but if you drink the output you'll be a very unhappy camper.

[Michael Redler]

Thanks Dean.
 
I went on the premise that purifiers were made of charcoal (so far, so good) 
but, had no background on how it's prepared.
 
I think you just discovered that I'm not a chemist.

Hi Michael,

I'm sure I will be corrected if I am wrong but I seem to remember from 
one of my other groups that charcoal would need to be converted to 
activated carbon via super heated steam this steam opens up millions 
upon millions of microscopic pores on the carbon which attract 
impurities in things like water and alcohol. After some reading 
apparently Charcoal can be used but it will need to be treated.


This is regurgitated information and I can not guarantee its accuracy 
especially because of my bad memory : )
1st. Soak the charcoal in a very good solvent to dissolve the tars 
present in the pores Ethanol is very good for this as it wont kill you.


2nd. Boil the charcoal in water for 15 minutes and then pour the water 
of the top to remove the floaties. Repeat until no more are present.


3rd. Heat in an oven at high temp until dry.

4th. Soak in clean water before using.

You can search the archives here for info on Activated Carbon and 
Charcoal

http://archive.nnytech.net/sgroup/distillers/
Or you can download a free Ebook on activated carbon from here

Hope this helps.

[Biofuel] A nice experience

[Pieter Koole]

Some time ago I wrote about my mistake, to not boil off the water out of
wvo, so I finished up with a lump of soap, glop or whatever we can call it.
Alltogether it was 1000 liters. Now I decided to try to break the soap with
phosphoric acit (75%) and let it sit for several weeks. The soap was cracked
and I was lucky to siphon from the top just over 700 liters of BD. I have
been driving on it, without any problems.
Maybe someone out there can do something with this information.
I have been thinking that I might be driving on FFA's at the moment in stead
of BD, but it works.

Met vriendelijke groet,
Pieter Koole
Netherlands.

Subject: [Biofuel] cell phones and safety
Date: Fri, 06 May 2005 07:36:14 -0500

Greetings Friends,

I find myself in need of doing a little preaching today.  Sorry, but for 
me, this is the best way I can deal with the horror of last night.


Last night a young women of 21 or so was driving down the highway talking 
on her cell phone and definitely driving with no care and attention to what 
she was doing.  I guess she thought that by staying mostly on the shoulder, 
it was safe to drive and talk.  Then she dropped her cell phone and reached 
for it.  A man, barely 10 years her senior who was riding his bicycle, died 
because of her actions.  Her life will never be the same, either.


As for me, I can not work to erase the memory of what I saw until he has 
had his day in court.


Please, turn your cell phones off while driving.  It was not just that she 
dropped that cell phone.  She did not see the cyclist, because she was 
distracted by her conversation.  He was plainly visible long before he was 
hit, I know, I watched the accident about to happen and it did.


Bright Blessings,
Kim

[Biofuel] good news, but solid glycerin problem

[Theo Chadzichristos]

Hey everyone,

Great news! I finally put 5 gallons of homebrewed BD in my old benz and 
it
loved it. I also finally made a 15 gallon batch in my processor and it came
out great. My Problem is that on my processor I have a cone on the bottom of
a 55-gallon drum where all the glycerin settles. I planed for it to be
liquid but it was solid. I used 52.5liters of oil, 8.5g of lye per liter,
and 20% methanol for my last batch and was wondering what I can do so it
doesnât solidify. I was thinking maybe draining it somewhere between 3-5
hours after I stop mixing instead of the next day. Any feedback would be
great.

Thanks again,

Theo Chadzichristos
