Hi David Agree with your comments about starch and alcohol. dont know if i'd like to try the dry fuel in a piston engine - I know coal powder wasnt terribly successful. But it should work fine in an IC or EC Turbine I imagine it would burn fairly clean however the grain has still got a lot in it that wont come out as energy or water so the pollution factor may be quite alarming and making straight starch from the feedstock would likely loose as much energy as in ethanol production regards john >Who remembers the gunpowder engine?
