I just went to this site, and would also like to see more data. I find it hard to believe he is not using some sort of ignition starter such as ether in the blend. It looks as though the biodiesel is just a substitute for kerosene in the normal diesel fuel mixture. He is using very little oil which may mean that the biodiesel is "oilier" than kerosene. If so, it may actually be less efficient than a regular kero mix. More data, please.
