Hello Chip Mefford.
First I want to thank you for your email, the server maintenance, and 
the expenses.
It will be great if the years of green technology and "how to do it" 
could be available in the future as a record.
I looked at FarmOS on the Youtube link, I saw great ideas but here most 
of the farmers are old people and their strengh needs a horse or an ox 
to help them for planting as my Grandfather did with old technology
Thank you for showing what you were doing at that farm, it is a new wave 
in agriculture from peasant peeople.
It is a leap for farming, taking an ancient technology to the present 
state of the art digital world. It is wonderful!

I would like you count me in.
Best Regards.

Good day all of you who are left,

I really want to thank everyone who has sent their
thoughts on taking the list down. There have been
some, , no, not some, all, great stories.

Before I take the list down, ,
I was wondering how many of you are still interested in keeping
something like this going.

reason I ask is that I am becoming involved in a
new software project that I find very exciting, and
hence have chosen to do the work to update my
respective servers, including the mailing list server.

Kind of a pain in the neck, I went through a life-change
over the last 6 years, and walking away from all things
IT was part of that. Since I had many dangling obligations
(being a denizen of the internet) I tapered it all down
to where about the only thing I was responsible for was
this mailing list. However, that particular attempt
at resolving some things in my life by not doing
systems administration have cropped back up again,
so that wasn't the fix for which I had hoped.

So, it doesn't make sense really to abandon all those
skills I had developed, even though I am moving into
my dotage, (heh) but rather to double down and dive back
in.

The project of which I speak is FarmOS

https://www.youtube.com/watch?v=bCOqg5iH6fM

Take a look, give me some feedback, if there is interest,
I'll migrate some or all of this list into a new
community.

Thanks kindly for your attention in this matter;

Re: [Biofuel] Plug-In Hybrid HUMMERs Headed For The South Pole On Biodiesel

2015-04-24 Thread Juan Boveda

Hello Darryl.
I think they need for that trip is to choose a biodiesel ready for low
temperatures like the used by jet planes, a winterized fuel prior it
is used in Antartica; that proccess is to expose fuel to freezing
temperatures equivalent to artantic conditions, give time to cristalize
and after that, pass it throught a filter the fuel to be used by
vehicles to avoid a thick mass of partly frozen biodiesel. The fraction
of longer carbon saturated fatty acid methyl esther will be separated by
cristalization and filtration and use only the liquid fraction.

Plug-In Hybrid HUMMERs Headed For The South Pole On Biodiesel

Stephen Edelstein

Apr 24, 2015

If you were going to drive to the South Pole, what vehicle would you
choose?

There's a team gearing up right now to undertake that very
adventure--using a pair of plug-in hybrid Hummers.

The mission is called Zero South, signifying the group's goal of being
the first to reach the South Pole without using any fossil fuels.

And the team's choice of vehicle wasn't an accident.

The intentional irony of converting a Hummer into a plug-in hybrid
had a certain appeal, according to a Zero South statement.

Zero South hopes to promote awareness of environmental issues, and
believes electrified Hummers will make excellent conversation starters.

We shall draft a symbol of military defense for the front lines of
environmental defense, expedition organizer Nick Baggarly declared.

There's a practical element to the choice of vehicle, too.

To tackle Antarctic ice and snow, the Zero South team needed a vehicle
with a wide track.

Each Hummer is equipped with a 3.2-liter six-cylinder turbodiesel
engine that will run on biofuel during the expedition.

There's also an electric motor for each axle, retaining the Hummer's
four-wheel drive capability.

Electricity is supplied by a 24-kilowatt-hour lithium-ion battery
pack, mounted in an insulated battery box to maintain consistent
temperature.

Green powertrains weren't the only modifications made to the pair of
Hummers.

The expedition vehicles features reinforced drivetrain and suspension
components, as well as upgrades allowing them to operate in
temperatures as low as -60 degress Fahrenheit.

Then there are those tank treads.

They're supplied by a company called Mattracks, which sells them as an
aftermarket add-on for Hummers and other SUVs and trucks.

On road tires, the plug-in Hummers are capable of an estimated 32
miles of electric range, although Zero South hasn't yet determined how
far they'll be able to go on the tracks.

It's also unclear where they would recharge while traversing Antarctica.

One of the vehicles is designated to tow a modified Airstream trailer,
nicknamed the Snowstream.

The entire journey is expected to span 1,200 miles; if successful,
Zero South says its vehicles will be the first hybrids driven to the
South Pole.

The group plans to document its journey on camera, and produce a
10-episode television miniseries and feature-length film for maximum
exposure of their proposed exploit.

[Biofuel] 110 kilometers on a liter of diesel, Volkswagen XL1 Plug-in Diesel Hybrid

First Drive: Volkswagen XL1 Plug-in Diesel Hybrid
By Brad Berman · June 26, 2013

http://www.plugincars.com/first-drive-volkswagen-xl1-plug-diesel-hybrid-127594.html 



A dozen years ago, Volkswagen embarked upon a project to design a 
vehicle that can travel 100 kilometers using merely one liter of diesel 
fuel. VW logically dubbed the car the L1. The company this week allowed 
a small group of American journalists to drive the fourth iteration of 
the car—this one known as the XL1—on a 40-minute trip near the company’s 
headquarters in Wolfsburg, Germany. I was part of the group that 
experienced the XL1’s iconoclastic blend of four efficiency strategies:


Plug-in hybrid power
Sleek aerodynamics
Severe light-weighting
Efficient (very) small diesel engine design
Combining these strategies has a multiplicative impact—allowing the XL1 
to beat its 100-km goal by 10 percent, providing 110 kilometers on a 
single liter of fuel. (That equates to about 260 miles per gallon.) 
What's even more impressive is the XL1's design—a fun, stylish piece of 
automotive innovation that updates car coolness for the 21st century, 
swapping out horsepower and brawn as the measure of appeal and 
attraction, with an irresistible high-tech quirky charisma.


Gutsy, Eco, Chic
he XL1 seats only a driver and a passenger to the side, staggered a few 
inches toward the rear of the car. The body design is wide in front, and 
tapers to much thinner proportions toward the back. While providing as 
much as 30 miles of all-electric capability from a 5.5-kilowatt-hour 
battery, stomping on the accelerator wakes up a 0.8 liter rear-mounted 
48-horsepower engine—just enough internal combustion propulsion, 
combined with electricity, to move the car along with brisk city traffic 
or not feel left behind on Germany's famed highways. When that small 
diesel engine comes online, it loudly clatters, nearly directly into the 
passenger cabin. In an effort to save weight, sound dampening was 
ignored—making every flutter of the engine, as well as every bump in the 
road or scraping screech from the car’s ceramic brakes—a visceral 
experience.


This intrusion into the cabin is part of the car's gestalt, along with 
its scissor doors, side-view cameras (to replace mirrors), and 
futuristic shape. Power steering was also eschewed in the name of light 
weighting, making turns at any decent speed an athletic feat not 
dissimilar to steering a Tesla Roadster. It all adds up to a ton of fun. 
Efficiency is not a matter of sacrifice or anemia. VW made the XL1 gutsy 
and chic.


Even the tiny slot of a passenger window, manually wound up and down, 
felt analog-hipster. Of course, the small opening will make it 
impossible to ever receive a Supersized fast food meal at a 
drive-through window. Just as well—there’s absolutely zero chance this 
car will make its way to the United States.


Read My Lips: De-mon-stra-tion

Volkswagen will use a manufacturing process that looks and smells a lot 
like mass production at its factory in Osnabruck, Germany—but merely 250 
XL1 units will be made. Approximately the first 50 will be put on loan 
to VIPs for a few weeks at a time, or to Germany-based customers who 
submit proposals to demonstrate how the XL1 can be incorporated into a 
daily sustainable lifestyle. The first of those loaners have already 
been given out. Next, a “real” production run of 200 cars—that's right, 
just 200 cars—will be sold or leased like any other VW automobile. No 
pricing info is yet available.


In a meeting with the journalists, Dr. Ulrich Hackenberg, a chief 
product specialist on the Volkswagen board, yesterday repeated the word 
“demonstration” when speaking about the XL1. He also said that the 
company needed to invest in a full range of automotive technologies and 
fuels (from compressed natural gas and fuel cells to plug-in hybrids 
and, of course, diesels) to achieve corporate global efficiency targets. 
More importantly, Hackenberg said the use of a very small diesel engine, 
like the XL1’s two-cylinder 830cc TDI Clean Diesel, combined with a 
parallel plug-in hybrid layout, could soon be applied to another VW 
model—perhaps a subcompact like the Up city car it sells in Europe.


It’s too early to tell if a prospective future model will be made in 
greater quantities, or reach American shores. But for me, at this stage, 
it’s enough to know that the slick head-turning ultra-lightweight XL1 
exists—and can serve as a compelling vision for quantum leaps in 
aerodynamics and high-tech appeal. The Cd of the XL1 is a super-slippery 
0.19. It weighs only 1,753 pounds, by virtue of its carbon-fiber body.


The car’s plug-in hybrid system consists of a 48-horsepower two-cylinder 
diesel engine, a 27-horsepower

Re: [Biofuel] As 300 Tons of Radioactive Water Leak From Fukushima, Never Believe The Nuclear Crisis Is Over

By Kiyoshi Takenaka and James Topham
TOKYO | Wed Aug 21, 2013 6:25am EDT

(Reuters) - Japan's nuclear crisis escalated to its worst level since a 
massive earthquake and tsunami crippled the Fukushima plant more than 
two years ago, with the country's nuclear watchdog saying it feared more 
storage tanks were leaking contaminated water.


The U.N.'s International Atomic Energy Agency (IAEA) said on Wednesday 
it viewed the situation at Fukushima seriously and was ready to help 
if called upon, while nearby China said it was shocked to hear 
contaminated water was still leaking from the plant, and urged Japan to 
provide information in a timely, thorough and accurate way.


We hope the Japanese side can earnestly take effective steps to put an 
end to the negative impact of the after-effects of the Fukushima nuclear 
accident, China's Foreign Ministry said in a statement faxed to Reuters 
in Beijing.


Japan's Chief Cabinet Secretary Yoshihide Suga called the situation 
deplorable, and the Nuclear Regulation Authority (NRA) said it feared 
the disaster - the worst nuclear accident since Chernobyl a quarter of a 
century earlier - was in some respects beyond the plant operator's 
ability to cope.


The plant's operator, Tokyo Electric Power Co, or Tepco, has been 
criticized for its failure to prepare for the disaster and has since 
been accused of covering up the extent of the problems at the plant. 
After months of denial, Tepco recently admitted the plant was leaking 
contaminated water into the Pacific Ocean from trenches between the 
reactor buildings and the shoreline.


It said on Tuesday that contaminated water with dangerously high levels 
of radiation was leaking from a storage tank - the most serious problem 
in a series of recent mishaps, including power outages, contaminated 
workers and other leaks.


The NRA said it was worried about leakage from other similar tanks that 
were built hastily to store water washed over melted reactors at the 
station to keep them cool. Water in the latest leak is so contaminated 
that a person standing close to it for an hour would receive five times 
the annual recommended limit for nuclear workers.


A spokesman for the NRA said the agency plans to upgrade the severity of 
the crisis from a Level 1 anomaly to a Level 3 serious incident on 
an international scale for radiological releases. An upgrade would be 
the first time Japan has issued a warning on the International Nuclear 
Event Scale (INES) since the three reactor meltdowns at Fukushima in 
March 2011. Explosions then led to a loss of power and cooling, 
triggering a maximum INES Level 7 at the plant.


HAUNTED HOUSE

NRA Chairman Shunichi Tanaka likened the stricken nuclear plant to a 
house of horrors at an amusement park. I don't know if describing it 
this way is appropriate, but it's like a haunted house and, as I've 
said, mishaps keep happening one after the other, he told reporters. 
We have to look into how we can reduce the risks and how to prevent it 
from becoming a fatal or serious incident.


He said the NRA would consult with the IAEA about whether it was 
appropriate to assign a rating to the leakage at the plant.


Japanese authorities continue to provide the Agency with information on 
the situation at the plant, and Agency experts are following the issue 
closely, Gill Tudor, spokesperson at the Vienna-based IAEA, said in an 
e-mailed statement.


The IAEA views this matter seriously and remains ready to provide 
assistance on request.


Each one-step INES increase represents a 10-fold increase in severity, 
according to a factsheet on the IAEA website. (www.iaea.org/) A Level 3 
rating is assigned when there is exposure of more than 10 times the 
limit for workers, according to the factsheet.


In an emailed comment, Andrew Sherry, director of the Dalton Nuclear 
Institute at the University of Manchester, said: Though serious, this 
leak is a long way from the Level 7 incident we were facing in 2011. The 
approach taken by Tepco to drain the tank, pump leaked water to 
temporary storage, and protect the drainage of contaminated water to 
ground water, is entirely sensible.


This incident highlights the need for an inspection program for these 
many hundreds of storage tanks, and the need to consider replacing 
bolted or sealed storage tanks, which were relatively quick to build, 
with a more robust welded design.


South Korea's Asiana Airlines Inc said it would cancel charter flights 
between Seoul and Fukushima city in October due to public concerns over 
the radioactive water leaks.


The city, around 60 kms (37 miles) from the nuclear facility and with a 
population of some 284,000, is a popular destination

[Biofuel] Solar Cell That Turns 1 Photon into 2 Electrons

The Solar Cell That Turns 1 Photon into 2 Electrons
M.I.T. researchers develop an organic solar cell that breaks 100 percent
quantum efficiency

By Seth Fletcher

Solar cells are picky. If an incoming photon has too little energy, the
cell won’t absorb it. If a photon has too much, the excess is wasted as
heat. No matter what, a silicon solar cell can never generate more than
one electron from a single photon. Such harsh quantum realities severely
limit the conversion efficiency of photovoltaic cells, and scientists
have spent decades looking for work-arounds.

Now, researchers at the Massachusetts Institute of Technology’s Center
for Excitonics have published a compelling case that the key to greater
solar efficiency might be an organic dye called pentacene. In today’s
issue of Science Daniel Congreve, Jiye Lee, Nicholas Thompson, Marc
Baldo and six others show that a photovoltaic cell based on pentacene
can generate two electrons from a single photon—more electricity from
the same amount of sun. Scientists have suspected for some time that
this might work; today’s paper is proof of concept.

The key is a phenomenon called singlet-exciton fission, in which an
arriving photon generates two “excitons” (excited states) that can be
made to yield two electrons. Previous researchers had accomplished
similar tricks using quantum dots (tiny pieces of matter that behave
like atoms) and deep-ultraviolet light. “What we showed here,” Baldo
says, in addition to using visible light, “is that [this process] works
very, very effectively in organic materials.”

Why it works is still not particularly clear, and for now, the pentacene
cell works only with an extremely narrow band of visible light. But
Baldo says it should be possible to create a pentacene coating for
silicon solar cells that boosts the total conversion efficiency from
today’s 25 percent to a shade over 30 percent—a significant jump.
Developing that technology is the obvious next step. “Can we apply this
thing as a coating on silicon?” Baldo says. “If we can do that, it would
have a pretty major impact on solar cell technology.”

TAM Airlines conducts first-ever Airbus biofuel flight using 
Brazilian-sourced jatropha-based kerosene blend



TAM Airlines A320 sets off on biofuel flight (photo: Airbus)
Tue 23 Nov 2010 – More aviation biofuel milestones were passed yesterday 
as TAM Airlines together with Airbus conducted Latin America’s first 
jatropha-based fuel flight, which also represented the first Airbus 
airliner to fly with a crop-based biofuel blend. Previous Airbus 
alternative fuel flights have been powered by gas-to-liquid (GTL) 
blends. Fuel for the TAM A320 flight was a 50% blend of locally-sourced 
Brazilian jatropha-based bio-kerosene and conventional aviation kerosene 
that had been processed by Honeywell’s UOP. Just one of the two CFM56 
engines was powered using the biofuel. Airbus estimates that sustainable 
biofuels could supply some 30% of commercial aviation as early as 2030. 
In May, 10 Brazilian organizations, including TAM and three other 
airlines, formed the Brazilian Alliance for Aviation Biofuels to promote 
biofuel initiatives in the country.


The 45-minute flight took off from and returned to Rio de Janeiro’s 
Galeão Antonio Carlos Jobim International airport and had 20 TAM and 
Airbus personnel on board. The technical flight was approved by Airbus, 
engine provider CFM International, and was authorized by aviation 
authorities in Europe (the European Aviation Safety Agency – EASA) and 
Brazil (National Civil Aviation Agency – ANAC).


“Airbus and TAM have taken an important step towards establishing an 
aviation biofuel solution that is both commercially viable and 
sustainable, with positive impact on the environment,” said Airbus’ 
President and CEO, Tom Enders. “This flight serves as evidence of the 
aviation industry’s commitment to advance on its self-imposed CO2 
reduction targets: carbon neutral growth from 2020, and working towards 
a 50% net CO2 reduction by 2050.”


Commented Libano Barroso, President of TAM Airlines: “This experimental 
flight materializes TAM’s participation in a vast project to develop a 
production chain for renewable biofuel, with the purpose of creating a 
Brazilian platform for sustainable aviation bio-kerosene.”


Airbus quoted studies that show the use of aviation biofuels derived 
from jatropha could reduce the sector’s overall carbon footprint by up 
to 80% compared with conventional petroleum-based jet kerosene.


In February 2008, an Airbus A380 aircraft completed the first ever 
flight by a commercial aircraft using synthetic GTL jet fuel and in 
October 2009, Airbus and Qatar Airways undertook a commercial passenger 
flight between London and Doha of an Airbus A340-600 with all four 
engines powered by a GTL blend (see story).


Synthetic jet fuels have been approved in 50-50 blends for commercial 
airline service use by fuel certification body ASTM International but 
such approval is still awaited for biofuel blends such as the fuel used 
on the TAM flight. This is anticipated to be forthcoming within the next 
few months, paving the way for their introduction into normal flight 
operations.


The Brazilian Alliance for Aviation Biofuels (ABRABA) initiative 
includes TAM and three other airlines: Azul, GOL and TRIP, as well as 
Brazilian aircraft manufacturer Embraer and the Brazilian Aerospace 
Industry Association (AIAB). Representing the biofuels industry are 
producers and developers of biomass sources such as jatropha, sugarcane 
and algae. The objective of the alliance is to promote public and 
private initiatives that seek to develop and certify sustainable 
biofuels for aviation (see story).


Azul is said to be planning a demonstration flight in the first half of 
2012 using a 50% blend of sugarcane-derived biojet fuel on a GE 
CF34-10E-powered Embraer 190 aircraft.


TAM and Airbus said they both supported the study and assessment of the 
sustainability and economic viability of implementing the bio-kerosene 
value chain in Brazil.

reduce its contribution to global warming.


KLM considers the development of biofuel to be a learning process; 
you have to start somewhere. By making the learning process visible, 
we will involve society in general in the process of creating 
sustainable aviation. Together with other stakeholders (including 
governments, the airline industry, suppliers, and customers), KLM and 
WWF-NL are attempting to achieve sustainable aviation, said Valarian

Great potential
He also noted that as part of this process, they are in constant 
pursuit of sustainable alternatives that will eventually be capable of 
meeting the overall demand for fuel. Supplies of used cooking oil are 
limited, but according to the energy report, there is great potential 
for the flow of waste and residue from forestry and agriculture 
industries. However, these 'second-generation' fuels are not yet 
commercially available,

he added.

According to the KLM country manager, supplies of sustainable 
feedstock for the production of sustainable biofuel are currently 
limited. However, we are still dependent on the planned processing of 
this feedstock, since this is not yet a common use of technology. This 
is why it is so important to stimulate the market for biofuel, he 
observed.
With KLM flights from John F. Kennedy International Airport in New 
York to Schiphol Airport in Amsterdam being partly fuelled by biofuel, 
KLM has demonstrated that the use of biofuel on airplanes is a solid 
concept that is here to stay.


It provides further proof of KLM's pioneering role in the development 
of sustainable biofuel. We are trying to realise this ambition with a 
step-by-step approach. The flights we have operated while using 
biofuel and our new initiative for this series over the next six 
months show that we are doing everything in our power to stay on 
track. We are nonetheless dependent on many factors, such as the 
availability of feedstock, he said.


According to the KLM blog, KLM has been operating a weekly flight from 
New York to Amsterdam, as of March 8, 2013, with the help of 
sustainable biofuel. It is an important step towards making air 
transport more sustainable. It is also a special milestone because 
KLM, Schiphol Group, Delta Air Lines, and the Port Authority of New 
York  New Jersey have joined hands to make these regular flights 
possible, stated the blog.


Every week, flight KL642, a Boeing 777-200 powered by sustainable 
biofuel, travels from New York to Amsterdam. With this step, KLM once 
again leads the way in the development of biofuel. Each of these 
flights will produce an average of 24 tonnes less CO2 than regular 
flights. This is comparable to the emissions of an average car driving 
around the Earth approximately four times (covering 160,000 
kilometres). The sustainable biofuel used for this series of flights 
will be refined from used cooking oil, which means there will be no 
impact on biodiversity or food production, the blog

[Biofuel] Warm Arctic, Chilly Mid-Latitudes in the north of the planet

2013-04-03 Thread Juan Boveda

Hello list members.
This is from NASA's and it shows how we disturbed the weather:

http://earthobservatory.nasa.gov/IOTD/view.php?id=80804src=eoa-iotd

[picture: temperature anomaly map]

While a high-pressure weather system brought warmer than normal
temperatures to Greenland and northern Canada in March 2013, much of
North America, Europe, and Asia shivered through weeks of unseasonably
cool temperatures. The contrasting temperatures are no coincidence: the
same unusual pressure pattern in the upper atmosphere caused both events.
Atmospheric pressure patterns are constantly in flux, as air masses of
differing temperatures and densities move around the skies. One key
measure of pressure that meteorologists track closely is known as the
Arctic Oscillation (AO) index, the difference in relative pressure
between the Arctic and the mid-latitudes. Changes in the AO have can
major impacts on weather patterns around the world.
When the AO index is in its “positive” phase, air pressure over the
Arctic is low, pressure over the mid-latitudes is high, and prevailing
winds confine extremely cold air to the Arctic. But when the AO is in
its ”negative“ phase, the pressure gradient weakens. The pressure over
the Arctic is not as low and pressure at mid-latitudes is not as high.
In this negative phase, the AO enables Arctic air to flow to the south
and warm air to move north.
In late March, the AO dropped as low as -5.6, one of the five lowest
values ever recorded by meteorologists. The temperature anomaly map
above, based on data from the Moderate Resolution Imaging
Spectroradiometer (MODIS) on NASA’s Aqua satellite, shows how this
affected temperatures in the Northern Hemisphere. The map displays land
surface temperature anomalies between March 14–20, 2013, compared to the
same dates from 2005 to 2012. Areas with above-average temperatures
appear in red and orange, and areas with below-average temperatures
appear in shades of blue. Much of Europe, Russia, and the eastern United
States saw unusually cool temperatures, while Greenland and Nunavut
Territory were surprisingly warm for the time of year.
Many parts of the Northern Hemisphere saw near record-breaking cool
temperatures as the value of the AO fell. The United Kingdom experienced
its 4th coldest March since 1962. In late-March, two-thirds of weather
stations in the Czech Republic broke records. Germany saw its coldest
March since 1883. And Moscow had its coldest March since the 1950s.

[Biofuel] Uruguay, Future Home of the World's Cheapest Solar Energy

Latin America Report: Uruguay, Future Home of the World's Cheapest Solar
Energy

By Renewable Energy World Editors
March 7, 2013

New Hampshire, USA -- Uruguay is about to offer contracts to buy power
from 200 megawatts of solar farms at $90/MWh, which is barely half the
cost of power in China and Germany.

President Jose Mujica is expected to sign a decree requiring national
power utility Administración Nacional de Usinas y Transmisiones
Eléctricas to buy electricity from projects at that rate. Developers
will have four months to submit proposals, with contracts handed out on
a first-come-first-served basis.

The question then becomes, who will respond? Most countries where solar
is being built offer higher rates than that, or extra tax incentives, as
in the U.S., said Bloomberg New Energy Finance analyst Jenny Chase.
Nevertheless, Ramon Mendez, director of energy at the Ministry of
Industry, Energy and Mining, claims several prospective bidders have
indicated they can sell at that price. If this round doesn't pan out we
just wait another couple of years for equipment prices to come down and
we try again.

Uruguay is already at the forefront of offering rock-bottom renewable
energy prices. Hydroelectric plants produce about 80 percent of the
nation's electricity, with costs averaging $80/MWh, according to Mendez.
A 2011 auction saw 17 wind project developers offering prices as low as
$63/MWh for new capacity.

I consider the commentary on the first part incorrect because it was not

Fernado Lugo by the Congress that has the power to do it as on any 
president and not paying attention that the former Vice President 
Federico Franco (now President) that he was elected by the poor, the 
worker and the rich at the same time with the same voting paper that I 
marked on 20/04/2008 and personally I liked both of them in the same 
line of 40,8% of the population at that time and both of them were 
democratically elected to lead the country but Fernando Lugo lost the 
political support of his own helping hand, its former ally the Liveral 
Party and Fernando Lugo only have a tiny political support group.

 Paraguay: Obama's Second Latin American Coup

 By Shamus Cooke

 June 24, 2012 Information Clearing House --  The recent coup 
 against Paraguay's democratically elected president is not only a 
 blow to democracy, but an attack against the working and poor 
 population that supported and elected President Fernando Lugo, whom 
 they see as a bulwark against the wealthy elite who've dominated the 
 country for decades.

 The U.S. mainstream media and politicians are not calling the events 
 in Paraguay a coup, since the president is being legally impeached 
 by the elite-dominated Paraguayan Congress. But as economist Mark 
 Weisbrot explains in the Guardian:

 The Congress of Paraguay is trying to oust the president, Fernando 
 Lugo, by means of an impeachment proceeding for which he was given 
 less than 24 hours to prepare and only two hours to present a 
 defense. It appears that a decision to convict him has already been 
 writtenŠThe main trigger for the impeachment is an armed clash 
 between peasants fighting for land rights with policeŠBut this 
 violent confrontation is merely a pretext, as it is clear that the 
 president had no responsibility for what happened. Nor have Lugo's 
 opponents presented any evidence for their charges in today's 
 trial. President Lugo proposed an investigation into the incident; 
 the opposition was not interested, preferring their rigged judicial 
 proceedings.

 What was the real reason the right-wing Paraguay Senate wanted to 
 expel their democratically elected president? Another article by the 
 Guardian makes this clear:

 The president was also tried on four other charges: that he 
 improperly allowed leftist parties to hold a political meeting in an 
 army base in 2009; that he allowed about 3,000 squatters [landless 
 peasants] to illegally invade a large Brazilian-owned soybean farm; 
 that his government failed to capture members of a [leftist] 
 guerrilla group, the Paraguayan People's ArmyŠ and that he signed an 
 international [leftist] protocol without properly submitting it to 
 congress for approval.

 The article adds that the president's former political allies were

Hello A.K. Ravishankar.
I think not only leaves should be considered but the complete vegetable

sugars for ethanol, oil contend or heat for steam production.
It depends on species, varieties, climate, soil, water, sunlight,
geographic place of growing, management of plants and soil, harvest
period of the year, etc.
In the tropics and subtropics with an adecuate rainfall, a fertile soil,
free of flooding, sugar cane in a short term is king with Leucaena and
Eucaliptus in the long run are much better for energy as heat, pulp see:
