Articles on Future Fuels-Jatropha
Jatropha is primarily a tropical genus of approximately 175
succulent plants, shrubs and trees (some are deciduous, like Jatropha curcas L.),
from the family Euphorbiaceae. Jatropha is indigenous to Central America, but
has been raised in other tropical and subtropical areas such as India, Africa,
and North America. Jatropha was initially used as a valuable hedge plant and was
exported to Africa and Asia by Portuguese traders. The flowers and stem of Jatropha
curcas have well-known medicinal properties, and the leaves are used for dressing
wounds. The oil has been used as an organic insecticide as well as an effective
treatment for snake bites and other ailments. Learn more: http://www.terasollabs.com/jatropha.htm
Use as Biofuel:

When jatropha seeds are crushed, the resulting jatropha
oil can be processed to produce a high-quality biodiesel that can be used in a
standard diesel car, while the residue (press cake) can also be processed and
used as biomass feedstock to power electricity plants or used as fertilizer (it
contains nitrogen, phosphorous and potassium). The plant yields more than four
times as much fuel per hectare as soybean, and more than ten times that of maize
(corn). A hectare of jatropha produces 1,892 litres of fuel. Learn more: http://en.wikipedia.org/wiki/Jatropha_oil
