"However, despite its abundance and use as an oil and reclamation plant, none of the Jatropha species has been properly domesticated and, as a result, its productivity is variable, and the long-term impact of its large-scale use on soil quality and the environment is unknown."
Most of the events of jets using fuel are mixes of jet fuels (not fully Jatropha, you still have to have other bio-fuels/petroleum jet fuels).
And algae grows basically everywhere lol, other than super cold locations. Jatropha only grows where, South America?
