Although his dedication towards improving the lives of tribals of Chattisgarh are laudable, the plan to grow jatropha has a lot of problems. First, there is not going to be enough yield per acre to even make a dent on conventional diesel consumption. Second, burning biodiesel still belches out nitrogen dioxide to the environment, instead of carbon dioxide. So, in effect, using biodiesel instead of convential diesel is still bad for the environment, infact much worse one could say.
