@McTag,
several plants do this, Ive been told by researchers. We make biodiesel in a small reactor and are using several plant derived Fatty acids. Ive been told that several species of PAtagonian wild potatos and the Jojoba plant also will produce a xcomplex sucrose based ester that is just like diesel and is energy dense. The big problem with all these plant methods is the way to exptract the fuel. Im still sold on the ALGAE reactors being worked out in the SW US(TExas A&M and RICE U) and in Algeria (set up by Planck Institute). The algae based fatty acids need to be turned into diesel fuel by an alcohol and Hydroxide "Esterification process" so they arent a complete "plant to tank" fuel, they do need a heat generating conversion process which generates a lot of glycwrine as a by product (we will have enough soap and candle raw materials).
NOW, if we could make wooden reactors and some diluent to carry the fungus diesel, we could have these on board our pickup trucks and generate our own fuels as we drive (JUST kidding).
They are finding all kinds of plants that generate esters and fatty acids for ready made diesel fuels. WE dont have any energy problem if we shifted to a diesel engine base.
