I've heard that there are environmental concernes with ramping up palm oil production that could be alieviated by using jatropha instead, which also produces more energy, or a higher quality fuel.
I'll be dammned, I've got a buddy who's got dozens of these growing in pots in his backyard (the Jatropha multifida, we usually call it Coral Plant) and I've got a big one that produces seeds all summer long (and in Florida, that's a long time) right next to me shower window. The butterflies love it.
My buddy got a visit from the Sheriff one time b/c of the similar leaves to marijuana to the uninformed.
