Alex,
You must have gotten smile out of this press release, knowing that members
of this list like Elsen and the Karves has been making cane coal for a few
years.

mpoverished Haiti has sugar to burn
Engineers: Cane charcoal could help solve cooking fuel problems
Thursday, August 3, 2006; Posted: 9:56 a.m. EDT (13:56 GMT)
(CNN) -- Little is simple in Haiti, not even boiling water.
Impoverished citizens of the Caribbean nation have long been lacking in many
regards -
- from overarching aims like fostering prosperity, health and stability to
more mundane
things such as electricity and appliances.
Even wood is in short supply, leaving many reliant on possibly toxic, often
ineffective
briquettes made from waste paper to cook.
The latter issue got the attention of Amy Smith and her cohorts at the
D-Lab, a hands-
on and instructional program dedicated to using engineering and technology
to improve
lives in the developing world.
"You couldn't even heat water with it, let alone boil water," Smith said of
the waste
paper briquettes after they were examined at the D-Lab's base at the
Massachusetts
Institute of Technology in Cambridge, Massachusetts. (Read more details)
Taking that fact and a host of other health, environmental and economic
issues into
account, Smith said, "We decided that there was a need for an alternative
cooking
fuel."
The requirements were basic but not necessarily easy to meet: The fuel had
to be
simple, effective, cheap and plentiful in Haiti.
Given that challenge, the D-Lab's engineers began sifting through -- and
burning --
garbage. They ultimately settled on sugar cane, a common crop in Haiti.
"Sugar cane [waste] works well because it's not used for anything else [and]
there's no
real nutritional value for it," said Smith. "And the charcoal that it
produces is pretty
good."
Heightened need
The problems with the waste paper briquettes often used by Haitian villagers
extended
well beyond their effectiveness.
For one, such briquettes' fumes posed potentially major health risks. This
issue is
especially critical in Haiti and other developing countries, where acute
respiratory
infections are a top cause of death for young children.
Breathing indoor cooking fires is typically a significant factor in such
illnesses, Smith
said.
Moreover, a high deforestation rate -- 98 percent of Haiti's landscape is
tree-free -- has
left Haiti lacking a wood supply and especially vulnerable to flooding and
landslides.
In September 2004, for example, Hurricane Jeanne killed more than 3,000
Haitians and
damaged around 300,000 homes.
The need to preserve whatever trees remain is especially critical, given
that forecasters
are predicting 8 to 10 Atlantic hurricanes this year.
For all these reasons, the D-Lab team went to work. Their first tasks: Pick
up the trash
-- direct from Haiti -- and then set it ablaze.
"We had a suitcase full of agricultural garbage," recalled Smith. "We had
sugar cane,
corn husks, peanut shells, corn cobs, everything."
The engineers were able to create a charcoal that could be produced easily
and at low
cost.
Traditional charcoal is available in Haiti but, like kerosene, is
prohibitively expensive. A
bag that lasts about 45 days costs about $70 Haitian dollars, but most
adults do not
make more than a few $100 per month, if that, according to Smith.
The MIT team then held a field trial in Petite Anse, a small and especially
poor fishing
village on Haiti's northern coast, working closely with local residents to
produce and
test the sugar cane charcoal.
In a case study produced after the trip, the D-Lab concluded that the final
product had
similar "energy density" (which relates to its heat and duration, thus
cooking capacity)
as wood charcoal and could be produced locally for about one-third of the
cost.
The advantages of sugar cane charcoal include improved taste, availability
and
economics, Smith said.
"This is a situation where you have a fuel [that] is cleaner burning ... And
being able to
provide alternative cooking fuels means people won't have to cut down
trees," Smith
said, calling it a "win-win project."
