In this case Castro is right...  One example is the price of corn in
Mexico is higher due to bio-fuels...

http://www.guardian.co.uk/cuba/story/0,,2045572,00.html

>>> The Cuban leader, Fidel Castro, today attacked George Bush's new-found fondness for biofuels, warning that food stocks for millions of people could be threatened.

Castro of course ignored the issue of global warning and energy
independence...  Taken out of these contexts, Castro had a free shot
to label Bush a monster...  But leaving out these related issues is
what makes this a biased and agenda driven faux news article...

jgg,

Biofuels are not a bad idea, but I doubt that corn is the long term
answer. As you say, the food issue. The govt./industry should take a
harder look at industrial grade hemp. It can grow in places where one
would not normally grow a food crop like corn. Hell, the stuff will
grow just about everywhere. The hemp seed oil can replace oil as not
just fuel but paint, plastics, etc. The fiber can be used for
eveything from paper to cloth. Much more versatile than corn.

NZ firm makes bio-diesel from sewage in world first
Email this storyPrint this story 12:00AM Friday May 12, 2006
By Errol Kiong
A New Zealand company has successfully turned sewage into modern-day
gold.

Marlborough-based Aquaflow Bionomic yesterday announced it had
produced its first sample of bio-diesel fuel from algae in sewage
ponds.

It is believed to be the world's first commercial production of bio-
diesel from "wild" algae outside the laboratory - and the company
expects to be producing at the rate of at least one million litres of
the fuel each year from Blenheim by April.

To date, algae-derived fuel has only been tested under controlled
conditions with specially grown algae crops, said spokesman Barrie
Leay.

Aquaflow's algae, however, were derived from excess pond discharge
from the Marlborough District Council's sewage treatment works. Algae
take most chemicals out of sewage, but having too many of them taints
the water and produces a foul smell.

Creating fuel from the algae removes the problem while producing
useful clean water, said Mr Leay. The clean water can then be used for
stock food, irrigation and, if treated properly, for human
consumption.

Mr Leay said the process could also benefit dairy farmers and food
processors as the algae also thrive in those industries' waste
streams.

And unlike some bio-fuel sources which require crops to be specially
grown - using more land, fuel, chemicals and fertilisers - the algae
already exist extensively.

To get the fuel, the algae are processed into a pulp before lipid oils
are extracted to be turned into bio-diesel

Challenging the bio-sceptic

  Taking on Trader Vic
All tanked up
Only fuels rush in
Fuel or food?
Billion $ bio-fuel plant for SA
Biofuels 'won't rock' industry

BIOFUELS are on the brink of becoming big business in Africa if one
believes in some of the content of the very elaborate invitation to
next week's Second Africa Biofuels conference in Midrand.
Trader Vic will be there and he will vigorously look for investment
opportunities (and scams) for his loyal followers.

The conference is spread over four days. It will cover 6 themes over
43 sessions and there will be 50 speakers. The invitation and summary
of the program is spread over eight pages of very fine print. Wow!
This is certainly the biggest event of its kind ever held in Africa.

Even in the heyday of the dot.com boom, conferences on the potential
of IT in SA barely took up a full day. Four days and 50 speakers must
surely bring some clarity as to how and where to invest in this
budding industry.

Absa is the platinum sponsor of this event followed by gold sponsor
Infinity, which is the marketing arm of De Beers Fuel of Naboomspruit,
a small little town in the Limpopo province. De Beers Fuel claims that
they currently have the capacity to produce 6 000 litres of biodiesel
per hour.

Biofuels from algae

They have not yet identified the basic feedstock as there is virtually
no commercial farming of sunflower or soybeans in the area.

But the real potential of De Beer Fuel and Infiniti apparently lies in
its agreement with Greenfield Technology Corporation (USA), they are
also present at the conference, to provide technology to produce
biofuels from algae.

"The first algae plant was erected in Naboomspruit and was inoculated
at the end of November 2006. One acre of sunflower produces 350 litres
of biodiesel and one acre of algae 40 000 litres", claims the summary
of the virtues of the De Beers Group. Now this is some real
potential.

Last time I looked one acre was about 4 000 square metres. The algae
must therefore have the potential to produces 10 litres of diesel per
square metre. This is such a high yield that one can virtually just
siphon the diesel off with a piece of hose pipe.

The average diesel bakkie travelling 20 000 km per year, will need
only about 2 000 litre of diesel and for that one would only need a
mere 200 square metres (about the size of the average suburban garden)
of algae, and Bob's your uncle. No more diesel from the blue pump for
me?

Algae diesel

Trader Vic will most certainly on behalf of his loyal follower's
research this opportunity next week. I was born, brought up and
schooled in Naboomspruit. I visited the town last Sunday but nobody
could point me in the direction of the algae farm of De Beer Fuels.

I know Naboomspruit is a particularly dry area especially this time of
year, but with such production potential I am sure one can sacrifice
the odd shower and rather tend your little patch of algae.

Fin24 will immediately dispatch a photographer to Naboomspruit if Frik
de Beers allow us to take pictures of the algae farm and production. I
will personally buy a couple of litres algae diesel to try in my
bakkie.

A lot has been written on the absence of meaningful progress at the
ethanol plant of Ethanol Africa in Bothaville the past week. I was
even honoured last week with a personal visit by Joe Kruger, the MD of
Ethanol Africa.

Kruger confirmed that the contract for the erection of the plant at a
fixed price of about R1bn is not yet in place. He also confirmed that
the finance for this project has also not yet been obtained.

Big saviour of the maize industry

He also predicted that the local maize price will decline to bring it
more or less in line with the Chicago price of about R1 200 per ton.

At that price the ratio between one ton of yellow maize and a barrel
of crude of just below 3 to 1 will be the same in SA as in the USA,
where corn (we called it maize in SA) is extensively used for ethanol
production.

The farmers will not be very impressed with this prediction of Kruger
as they saw in Ethanol Africa the big saviour of the maize industry.

Johan Hoffman, the CEO of Ethanol Africa, and his friend Gregor
Paterson-Jones of Sterling Waterford will both present papers at the
conference apparently on the viability and financing of an maize to
ethanol plant in SA.

This should clarify all the uncertainly about the plant at Bothaville
for the farmers that have invested R24m in the project to date a well
as other business people in Bothaville that are eager to invest in the
spin-offs of the plant.

Fill up with Sasol

Trader Vic, who is from farming stock himself, is really looking
forward to the opportunity to add a few litres of Bothaville "woema"
to the tank of his car and drive safely back to Gauteng before the end
of next year.

A prospectus with clear assumptions on the viability of Ethanol
production in SA would also be very welcome.

Hopefully I will be in a better position after the elaborate
conference on Biofuels next week to advise in more detail on the
investment and other opportunities in this industry.

In the meantime fill up with Sasol (that refers to both fuel and
shares) and don't kill the algae in your swimming pool

UN: 'World hunger increasing'

Stockholm - Rising production of biofuels from crops might complicate
UN goals of ending hunger in developing countries, where 850 million
people do not have enough to eat, a senior UN official said on
Wednesday.
"There's a huge potential for biofuels but we have to look at ...
competition with food production," said Alexander Mueller, assistant
Director General of the UN Food and Agriculture Organization (FAO).

Production of fuels from sugar, maize, soybeans and other corps is
surging, spurred by oil prices above $70 a barrel and a drive for more
environmentally friendly fuels from renewable sources.

"This is a completely new issue, we only know that this has impact on
the question of feeding the world," he told a news conference during a
meeting of 1 500 water experts in Stockholm.

Still, he said that a surge in biofuels production in the past year or
two had not hampered food supplies. "We have to find out what the
situation will be in 5 to 10 years ... a lot of research has to be
done," he said.

Biofuels now make up only a fraction of a percent of world energy use
but have an economic potential to rise to perhaps 6% by 2050,
according to rough FAO estimates.

"This is an emerging issue with no clear figures and no guidelines,"
Mueller said. The rise of biofuels could also strain world water
supplies - about one in three people live in areas where water is
scarce, he said.

He also said that the world would need better management of fresh
water to "feed all the people and to produce energy for the world."

Mueller said biofuels presented one of three major challenges for
farming, alongside climate change and a rising world population.

Food output would have to rise by 40% in the next 25 years to keep
pace with a rise in the world population to nine billion people. That
in turn will strain demand for irrigation with one in three people
living in regions with water shortages.

And climate change might bring more droughts, floods, heat waves and
erosion. Most scientists say that emissions of greenhouse gases,
largely from burning fossil fuels in power plants, factories and cars,
are warming the planet.
