Myth. Jatropha is only promising source of Biodiesel.

Fact. There are thousands of sources for Biodiesel. Indian scientists
have prepared the list of over 300 potential species for biodiesel.
Most of these species are indigenous. Biodiesel can be prepared by
plastic, and even by weeds like Cassia tora and Calotropis gigantea
without investment of millions and causing damage to environment like
large scale Jatropha plantation.
