RE: [Biofuel] Biofuel as a rural community development project inMozambique

2005-06-30 Thread Armando R
Alexis,

With the current oil prices I am sure many things can be done in rural
communities in Mozambique in the area of biofuels.
I would leave fuel ethanol for the sugar cane factories to produce. It can
be mixed up to 10% in gasoline as the Malawians are doing, apparently.

The rural poor buy kerosene (and sometimes gasoil) for illumination at very
high prices, above USD1000,00 per cubic metre in many remote areas, were
vegetable oil (coconut oil for instance) could be used. This would be a very
small-scale project, but the local alternative price of the raw material
should be investigated. I have done some calculations on coconut oil and
found out that the raw material (copra) is the most important single cost in
the production of oil.
The vegetable oil could also be used in diesel engines running the
small-scale mills scattered around the rural communities.

Best regards,

Assunto: [Biofuel] Biofuel as a rural community development project
inMozambique

I am toying with the idea of trying to set up a pilot rural community
development project involving biofuel (bioethanol or biodiesel or SVO,
whichever is most appropriate) in Mozambique. I am hoping that you can give
me your opinion and advice on the technical feasibility, commercial
viability and ultimately, long-term sustainability, in a poor isolated
African rural setting, of small-scale, community-based, locally-run biofuel
production. If anyone has had experience of a similar project, I would be
extremely interested to have information about that.

Am I right in thinking that the technical feasibility is beyond question?
Bear in mind that we are talking about very isolated and poor communities
where everything has to be low-tech and low-maintenance. On the basis of
this criterion, biodiesel appears to be the most appropriate fuel as it can
be used in diesel vehicles/machines/generators (even very old and rickety
ones?) with no engine modifications. We can discount the issue of having to
change filters initially because of accumulated petrodiesel deposits falling
off (we could include the cost of new filters in start-up subsidies). We
also don't need to worry about problems with cold starts, since Mozambique
is a tropical country.

I am more concerned about the question of commercial viability. The project
will only be replicable on a larger scale and sustainable in the long term
if, after initial start-up costs, every link in the value chain has an
incentive to participate and it is profitable for all concerned (i.e. the
anticipated gains should outweigh the expected costs, including the
opportunity cost of doing something else).

a) Inputs: Local farmers will have an incentive to supply the biofuel
production facility with feedstock only if prices paid and quantities
required by the production facility are stable and remunerative compared to
undertaking other activities, such as growing other crops for other
purposes.

b) Production: Local entrepreneurs will have an incentive to make
investments in biofuel production facilities and operate and maintain those
facilities only if they can sell their fuel at a remunerative price, i.e. if
they can compete against fossil fuels (whether locally, nationally,
regionally or globally, depending on the scale of production).

c) Demand: We know that the world market for biofuels is growing rapidly and
that the policy environment is becoming extremely favourable. However,
supposing, as is most likely to be the case, that local biofuel is most
competitive on the local market (and least competitive on the global market,
where it has to compete with industrial-scale production), there must be a
critical mass of buyers on that market, i.e. local communities must have the
desire / ability to invest in machines, vehicles or generators, and the
ability to pay for biofuel on a regular basis to run those machines.

I guess the root question is the following: is the current situation in
rural southern Africa - no biofuel production - a market failure that could
be resolved by kickstarting a virtuous cycle in the sector with start-up
outreach and support activities and subsidies, or is it simply not an
economically viable sector except with permanent subsidy and support?

It seems to me that, to answer this question, there are three crucial cost
assessments which need to be made:

a) Start-up costs: the required investments by farmers, by local biofuel
entrepreneurs, by future biofuel consumers, and to what extent can/should
outreach and support activities subsidize these fixed costs?

b) Price and availability of feedstock: How will local feedstock production
compare to growing other crops or

former officials. Maybe this war game was only an alibi, to be able to

 Outcome Grim at Oil War Game
 Former Officials Fail to Prevent Recession in Mock Energy Crisis
 By John Mintz
 Washington Post Staff WriterFriday,
 June 24, 2005; Page A19

http://www.washingtonpost.com/wp-dyn/content/article/2005/06/23/AR2005062301896.html

 The United States would be all but powerless to protect the
 American economy in the face of a catastrophic disruption of
 oil markets, high-level participants in a war game concluded yesterday.

 The exercise, called Oil Shockwave and played out in a Washington
 hotel ballroom, had real-life former top U.S. officials taking on
 the role of members of the president's Cabinet convening to
 respond to escalating energy crises, culminating in
 $5.32-a-gallon gasoline and a world wobbling into recession.

 The American people are going to pay a terrible price for
 not having had an energy strategy, said former CIA director
 Robert M. Gates, who took on the role of national security adviser.
 Stepping out of character, he added that the scenarios portrayed
 were absolutely not alarmist; they're realistic.

 The exercise began with ethnic unrest in Nigeria, leading to
 the collapse of the oil industry in that west African nation.
 Then al Qaeda launched crippling attacks on key energy
 facilities in Valdez, Alaska, and Saudi Arabia.

 But the war game's participants -- including former CIA director
 R. James Woolsey, former Marine Corps commandant Gen. P.X. Kelley
 and former EPA administrator Carol Browner, soon realized the
 U.S. government had few options in the short term to
 prevent an economic crash in this country and worldwide.

 When the exercise's planners first met last year, oil was in
 the $40-a-barrel range. As they fantasized where oil prices
 would be for the war game's start in an imagined late 2005,
 they said, they set them at $58 but worried they were being
 absurdly pessimistic. Yesterday, the closing price for
 a barrel of oil was $59.42.

 The war game players also referred several times to other
 real-life events of today. A major feature of the exercise was
 how China's voracious appetite for oil is driving up world prices,
 and only yesterday it was announced the Beijing government, in a
 bold and unprecedented act, is bidding to buy the U.S. oil
 company Unocal.

 The exercise was organized by two nonprofit groups that focus on
 the national security implications of U.S. dependence on foreign oil:
 the National Commission on Energy Policy and
 Securing America's Future Energy (SAFE). The scenarios were
 dreamed up by a team of former oil industry executives and
 government officials, including Rand Beers, a White House
 counterterrorism official who quit in 2003 to protest the Iraq war.

 The underlying situation dramatized in the exercise -- and accepted
 by most energy analysts -- is that tolerances are so tight between
 supply and demand, that even small disruptions in the delivery of
 oil and natural gas can cause cascades of unpleasant developments.

 The war game contemplated that when oil prices spiked and the
 Cabinet met to consider its options, it realized it had
 almost no clout to influence events.

 The standard response, drawing on the Strategic Petroleum Reserve,
 was symbolic at best. The president should not give in to
 Saudi offers that the kingdom would lower prices if he
 stopped pressing for Saudi democracy, the participants agreed.
 Within weeks conditions were worsening -- the Valdez oil terminal
 was on fire, as was a major Saudi oil port, and Western technicians
 were being killed there.

 Foreign oil firms soon pulled tens of thousands of workers
 out of Saudi Arabia. Suddenly lacking technical expertise,
 Saudi facilities could no longer play their decades-long role
 of guaranteed swing provider of oil in response to disruptions
 elsewhere. As the global recession deepened, there was no
 central banker of oil to smooth out temporary dislocations.

 The participants concluded almost unanimously that they
 must press the president to invest quickly in promising technologies
 to reduce dependence on overseas oil, such as hybrid cars powered by
 gasoline and plug-in electricity; and cars that run on fuels
 derived from prairie grasses, animal waste and other products.
 They all agreed these projects would take years to yield any
 benefit but should not wait for the kind of crisis they were dramatizing.

 If you want to put a frown on the face of [Saudi] Wahhabis,
 talk about 100-mile-per-gallon vehicles, Woolsey said.
 We don't need a Manhattan Project to do it.

Believe me, with the amount of smoke coming from some of the exhausts 
its as if the vehicles were running on turf. However that route (pardon 
the pun) is being stopped since the government environment body has put 
a stop to the erosion of the countryside by turf-cutting.


Unfortunately Ireland is becoming more and more a car-oriented country 
and cyclists have to take to the pavement/footpath to feel safe. This is 
in turn desensitising car drivers to the presence of other road users, 
teaching cyclists to ignore correct rules of the road and cause even 
more use of cars as parents consider it safer to drive their kids the 
whole half mile to school rather than have them walk.

The price of gas in UK is striking!  Attached is a fuel price report
published by The Automobile Association of UK.  I calculate the US
dollar cost of a US gallon of 95 octane(don't know ethanol content)
purchased in the UK to be $5.77.  This is closer to the Ireland cost
quoted below vs. the England quote.  Actually, this report shows Irish
gas costing more than English.  It also interesting to note that tax
accounts for 69.9% of the total cost!  Can that be right!  In Missouri
we pay $.3543/gallon or about 16%.

Title: RE: [Biofuel] Biofuel as a rural community development projectinMozambique







  
  

  
  
  Here is something from another list i am on.
  
  interesting numbers
  mel
  
  funny you should mention this. while i was at a biodiesel 
  conf in nh last week, a speaker from nh dept of agriculture ,dick 
  uncles ,had some of the useful data.
  soy- 35 bushels- at 20 cents per pound oil 
  (1.20/gallon)$200
  sunflower- 1200 lbs- at 35 cents per pound oil (2.10/gallon ) 
  $147
  hay- 2 tons- $240
  corn silage- 20 tons- $600
  apples- 240 bushels- $2880
  corn- 70 cwt. $3000
  berries- ? $5000 up to $1
  he didn't mention capital costs or other inputs (fertilizer, fuel, 
  plastic, labor) 
  i would supplement this with my quick analysis:
  1 acre is 43560 sq.ft.
  solar thermal output is about 1-2 gallons of fuel oil equivalent per 
  sq.ft. per year in our climate. so at $2/gallon, annual thermal output of 
  an acre would be $18. capital cost of such a 2500 kw 
  (thermal) system about $2.5 million for an roi of 7% , thermal 
  efficiency about 50%
  solar pv output is about 10 watts per sq.ft and 1-1.5 kwh per watt per 
  year so at 10 cents per kwh its value would be about $5. capital cost 
  of such a 500kw system about $5million for an roi of 1% . electrical 
  efficiency about 10%
  note this does not take into account some of the inevitable 
  selfshading, but that would reduce output by less than a factor of 2.
  clearly direct production of electricity or thermal energy is a lot 
  more efficient than agricultural, but a lot more capital intensive. 
  another speaker from unh mike briggs mentioned the potential for more 
  efficient conversion of sunlight to oil by algae, but clearly capital 
  costs and water would be an issue.
  as land values increase (moving from rural to urban) the direct use 
  increases in attractiveness. afterall, the colllectors and panels can be 
  mounted on bldgs integrally.
  its interesting to note that property taxes alone in nh at $20/1000 
  limit agricultural use to land worth less than $1/acre. (my 10 acre 
  suburban lot was just assessed at 16 so i'm already over the limit 
  (except for berries))

[Biofuel] Cross Posted Reply -- Re: The Cost of Alternative Energy

2005-06-30 Thread Michael Redler


There is a lot of debate about the different choices for alternative energy and which one is "better".

While I don't disagreewith Barbara's assessment, there also needs to be a parallel discussion about what technology is the most appropriate for a given situation. Even at 100% efficiency, solar panels would be more of a challenge for powering cars than the transportability of liquid fuels.

It's also important to keep in mind that energy technologies used in combination may yield some of the most desirable results.

Look at the table below and ask yourself:


What if the boiler heat source was a solar concentrator and the pumps and mixers were runfrom PV?

funny you should mention this. while i was at a biodiesel conf in nh last week, a speaker from nh dept of agriculture ,dick uncles ,had some of the useful data.
soy- 35 bushels- at 20 cents per pound oil (1.20/gallon)$200
sunflower- 1200 lbs- at 35 cents per pound oil (2.10/gallon ) $147
hay- 2 tons- $240

corn- 70 cwt. $3000
berries- ? $5000 up to $1
he didn't mention capital costs or other inputs (fertilizer, fuel, plastic, labor) 
i would supplement this with my quick analysis:
1 acre is 43560 sq.ft.
solar thermal output is about 1-2 gallons of fuel oil equivalent per sq.ft. per year in our climate. so at $2/gallon, annual thermal output of an acre would be $18. capital cost of such a 2500 kw (thermal) system about $2.5 million for an roi of 7% , thermal efficiency about 50%
solar pv output is about 10 watts per sq.ft and 1-1.5 kwh per watt per year so at 10 cents per kwh its value would be about $5. capital cost of such a 500kw system about $5million for an roi of 1% . electrical efficiency about 10%
note this does not take into account some of the inevitable selfshading, but that would reduce output by less than a factor of 2.
clearly direct production of electricity or thermal energy is a lot more efficient than agricultural, but a lot more capital intensive. another speaker from unh mike briggs mentioned the potential for more efficient conversion of sunlight to oil by algae, but clearly capital costs and water would be an issue.
as land values increase (moving from rural to urban) the direct use increases in attractiveness. afterall, the colllectors and panels can be mounted on bldgs integrally.
its interesting to note that property taxes alone in nh at $20/1000 limit agricultural use to land worth less than $1/acre. (my 10 acre suburban lot was just assessed at 16 so i'm already over the limit (except for berries))

I'm getting a 1965 Royal Enfield Bullet ready for the road.  It is 
powered by a Lombardini Greaves 325 cc diesel.  Hopefully it will go 
50 mph on B100 and get about 150-200 mpg.  Does anyone have 
experience with these motorcycles?  I believe they were available in 
the UK and in India.  Wish me luck.

have such a bike. But best of good luck anyway Todd. Any pictures?

Re: [Biofuel] fuel efficient cars

2005-06-30 Thread Hakan Falk


Hi,

When I did a part of the military service early 1960th 1,100 km north of 
Stockholm, I did this stretch in my 1955 VW on 80-90 liter. The 500cc one 
cylinder BSA I had, took about half of it and could do around 160-170 kmh. 
I also had a Plymouth V8 and it took 4-5 times more than the VW, but did 
180 kmh with ease. That was the days when gas was really cheap. The first 
50 cc moped I had, in Sweden they were modified to a speed limit of 30 kmh, 
took around the same or a bit more as the VW L1 and a bit less than L3. 
Fuel efficiency came a long way since then, but the relative difference 
between US and European vehicles seams to be the same. The same can be said 
for the higher fuel cost in Europe, were more than the financial gains has 
gone to the governments in taxes. Fuel costs per liter in Europe is around 
the same as per gallon in US. No wonder that Detroit/oil industry does not 
want fuel efficient cars. LOL

Re: [Biofuel] fuel efficient cars and motorcycles

2005-06-30 Thread Hakan Falk


Mopeds are defined by the engine and weight,
the weight I do not remember straight off but the
engine had to be under 50 cc. I Sweden they had
an additional restriction and that was that they
would not go faster than 30 kmph, which was
achieved by reducing the carburetor intake and
I do no know many youngsters that did not learned
how to handle a drill. LOL

In Sweden the moped do not require license, but
you have to be 15. I bought my first when I was 12,
for money that I earned by putting scrapped radios
together to working ones. I was hanging out with two
workshops, one was the radio  TV and the other
was a very nice gunsmith. I was competing in target
shooting and still have a number of silver plates and
pieces from that time 12 to 16. An other interest I had,
was horseback riding, which I started with when I was
9 years old. The Stockholm racing track was nearby
and I worked with horses on the school leaves, did
trainee races when I was 14, but then I became too
large and heavy.

Light motorbike, 75 kg and max 200 cc, license you
can take at 16 and I bought my first, when I was 14,
a 125 cc old Husqvarna. Got caught for illegal driving,
but was too young and they lost the record, so I could
take the license when I was 16 anyway.

Heavy motorbike and car, the age in Sweden is 18 years.

[Biofuel] White emulsion

2005-06-30 Thread fil_paulette

Hello everyone again,

Yesterday a person I know, gave me 1000 liters of out of validation virgin 
oil. I'm thinking making biodiesel with it so I don't see a problem with using 
it.
I did a titration using fenolftalein just like I did for passed batches, but 
this time I spended 5 ml of NaOH instead of the usual 1,0 - 1,5 for OVU 
titration (STRANGE). 
My short experience tells me that is something wrong with this oil, maybe too 
much FFA's formed with oxidation since this oil was stored for a long time.
By my calculations, in a mini-batch of 500 mL of this oil is necessary 4.250g 
of NaOH. OK, so I did it. I put 500 mL of oil plus 100 mL of ethanol with pre-
mixed 4.250g of NaOH in a erlenmeyer baloon with agitation and temperature 
control (55ºC)
The reaction went very well with beautifull colors. After 2 hours I stop 
heating and agitating and I let it setlle. The separation was spectacular, in 
15 minutes I've got almost colorless biodiesel in top and dark brown Glycerin 
and FFA's in the bottom.
So far so good.
I've notice that the quantity of glycerin and FFA's was excessive (about 180 
mL) usually it's 80 mL in a 500 mL of oil batch.
So I think, OK this oil got a lot of FFA's that's why I've got a larger volume 
of the heavy fase.
When I tried to wash the biodiesel with tap water, it formed a white emulsion. 
I've waited a long time but there was no separation, absolutely nothing.
What happened??
What am I doing wrong
Can I make biodiesel with this oil?

Sorry about my english

Thanks a lot

Re: [Biofuel] re property taking supreme court

2005-06-30 Thread marilyn
The white house resident has had his own experience with 
eminent domain. It made him a wealthy man.

http://www.libertypost.org/cgi-bin/readart.cgi?ArtNum=100228

Back in 1989, Bush hauled in the moolah on the stadium built in 
Arlington, Texas for the Texas Rangers. What's interesting about  
this one is that the Texas legislature passed a bill allowing the 
private corporation that owned the Rangers to exercise eminent 
domain, normally a power reserved for public entities.

We're all pretty familiar with condemnation for public projects. It's 
what the Army Corps of Engineers does to build flood-control 
dams or Municipalities do to construct water mains or Highway 
Authorities do to obtain rights-of-way. In the Texas Rangers case 
the condemnation was on behalf of a handful of private 
individuals, one of whom was George W. 

This surprising form of socialism with baseball teams 
condemning private property for new stadiums is now quite 
common in the US. It had a particularly sordid ring in the Texas 
deal. 

This private corporation condemned not only enough land for a 
spanking new baseball stadium, but also took an additional 300 
acres - yes 300 acres - of surrounding land for commercial 
development. Arlington residents floated most of the package 
with jacked-up taxes. These paid for the bonds needed to buy 
the land. It seems that our no-tax President wasn't ideologically 
opposed to increasing taxes if it padded his own bank account. 

The padding was generous: Bush made out like a bandit with 
his initial investment of $640,000 zooming to a cool $15.4 million 
in 1998 when he sold out.

Back in 1989, Bush hauled in the moolah on the stadium built in 
Arlington, Texas for the Texas Rangers. What's interesting about  
this one is that the Texas legislature passed a bill allowing the 
private corporation that owned the Rangers to exercise eminent 
domain, normally a power reserved for public entities.


We're all pretty familiar with condemnation for public projects. It's 
what the Army Corps of Engineers does to build flood-control 
dams or Municipalities do to construct water mains or Highway 
Authorities do to obtain rights-of-way. In the Texas Rangers case 
the condemnation was on behalf of a handful of private 
individuals, one of whom was George W. 

This surprising form of socialism with baseball teams 
condemning private property for new stadiums is now quite 
common in the US. It had a particularly sordid ring in the Texas 
deal. 

This private corporation condemned not only enough land for a 
spanking new baseball stadium, but also took an additional 300 
acres - yes 300 acres - of surrounding land for commercial
