Jet Fuel of the Future: Made from Plants

Early afternoon in Florida and it is 93 F (34° C) with 51% humidity. Quite warm. The only plants that seem to thrive in the endless Florida heat/humidity are the Jatropha species, pictured here.

This plant is alternately called Coral Bush, 'Nutmeg,' or Nettlespurge. Scientifically it is Jatropha multifida L.


Jatropha are resistant to most pests and bloom constantly through the wicked heat of a Florida summer.

The USDA lists 14 species of Jatropha and 21 taxa overall. All of the Jatrophas are being studied as potential biofuels because of their prolific nut production characteristics. More on biofuels below. I have several hundred Jatropha nuts drying for future plantings in recycled juice containers.

Mature Jatropha plants produce separate male and female flowers so one needs only one bush to manufacture nuts. The plant and its flowers contain many compounds that are highly toxic. Resistant to drought and pests, this plant produces seeds averaging 35% oil, thus it is being studied for future use as a biofuel.
