Haiti's Hopes for Biofuels Rest on Jatropha Plant

Jatropha could provide a cheap source of fuel for rural areas that are cut off from the nation's electricity grid. With a hectare of jatropha seeds selling for about $600, it could become an important new cash crop.

This is an interesting agricultural product that might work very well in Haiti. Economic utility however might be limited to underdeveloped rural economies. I do not believe that there are any mechanical methods of harvesting the seed pods. And if there is, I'd like to see the energy used to harvest versus the energy received from the plant. Anyone have more information?

On the topic of algae's future potential:

What would happen if Haitians did plant Chinese Tallow or Jatropha and then decided later (for whatever reason)that they didn't want it? The USDA article suggests that Chinese Tallow would be difficult and probably expensive to irradicate. What about Jatropha? I think everyone would agree that we want to avoid irreversible effects and irretrievable committment of resources. So, I would encourage those interested in introducing new (exotic) cash crops to look at the whole ecological picture and investigate thoroughly before investing in a renewable energy venture that may actually have long term adverse ecological effects. I advocate use of the precautionary principle.
Thanks for considering these thoughts and good luck to those involved with the trials in Port-au-Prince!

I'm not familiar with Jatropha's chemical characteristics (e.g. is it allelopathic like Chinese Tallow?) or the dispersal mechanisms (e.g. birds, wildlife, wind, water?) or if Jatropha has the potential to be invasive in Haiti. If it is easy to confine in cultivated fields and is not allelopathic, Jatropha would be worth investigating further. Hopefully it would produce the desired economic results without causing long term ecological damage. Note that if Jatropha is allelopathic like Chinese Tallow, it might change the chemical characteristics of the soil and inhibit growth of native plants or food crops.

I volunteer for the National Park Service in their invasive plant control efforts and I worked in rural areas of the Dominican Republic close to the Haitian border for a couple of years.

I generally support the idea of harvesting and using invasive plant species as a source for biofuel--in fact, I often wish I could send all the weeds I pull to a plant for processing. However, I would be EXTREMELY hesitant to start introducing invasive plants to new areas. Especially in island environments, where there tend to be many endemic species, invasive species could quickly jeopardize the continued existence of many species not found anywhere else on earth. While many species may have already been extirpated from Haiti's side of Hispanola, the Dominican Republic is generally in better shape ecologically speaking, but both countries probably still have some endemic species that could be affected by the introduction of additional exotic plants.

Will biofuels help or enslave/starve the poor? In either case, they are turning out to be, pound for pound, worse for global warming than coal.

http://www.guardian.co.uk/Columnists/Column/0,,2206002,00.html

"Yes, it can grow on poor land and be cultivated by smallholders. But it can also grow on fertile land and be cultivated by largeholders. If there is one blindingly obvious fact about biofuel, it's that it is not a smallholder crop. It is an internationally traded commodity that travels well and can be stored indefinitely, with no premium for local or organic produce. Already the Indian government is planning 14m hectares of jatropha plantations. In August, the first riots took place among the peasant farmers being driven off the land to make way for them."

To Filip de Ruwe: The site Bioenergy Wiki has a large section on biodiesel from algae. This is an exciting concept, especially when you consider the theoretical yield of up to 5000 gallons/acre/year from this technology. In addition, there is the value of using this technology for carbon sequestration. Large farms around coal-fired power plants could remove 75% of the carbon dioxide emissions from those sources. As to strains, there are experiments going on right now on DNA modification of some of them to increase their yield.

Has there there been much research into which organic based bio fuels yield the most energy ?What about algae?

Thanks for the link to the Chinese Tallow, Walt. If I have heard of it before then it has faded from my memory. All of the traits that make i a nasty, invasive species make it a great renewable resource. Odd that no one has mentioned the comparison in all the other articles I have read about jatropha.

In this article I found it interesting that the farmers would be paid by the hectare instead of by the ton as with other commodities. I suspect Kathleen was doing some math for us since we don't have the knowledge of the yield for jatropha in Haiti nor what the price will be when the jatropha is sold. We will just have to trust Ms. Robbins that the presumptions she has made are correct.

Mr. Valme seems to have a level-headed plan. Why choose between food and fuel when you can produce both? Refreshing logic that is so scarce in the renewable energy arena.

JATROPHA mechanival harvesting, answer
Olive groves in Italy use a mechanical harvester this same machine can be used on Jatropha. problem is Jatropha has no season one can only hand harvest yellow fruit as green fruit seeds will not have too much oil content.
harvesting should be kept manual as it will increase farmers income especially in this country (Indonesia)

Anyone interested in the Jatropa Nut should also read this atricle by the USDA about the Chinese Tallow Berry Tree which they classify as a weed. http://www.nwrc.usgs.gov/factshts/154-00.pdf
It is used as an oil fuel,charcoal, in soap making, and for making alcohol. It has virtually invaded the US Gulf Coast and we should figure out how to put it to use. Even Benjamen Franklin knew of its properties.

The Jatropa has a very high yeield of oil per acre, up to 435 gallons according to some reports. Another high yield plant is the Chinese Tallow Berry, a weed that yields up to 500 gallons per acre. Having spent a great deal of time in Haiti, I believe this program will prove to be of great value to the Hatian people. I'm sure some genius will develop a mechanical picker for either the Jatropa nut or the Chinese Tallow Berry
Good luck with the program!
