It's been a while since I put a way my Pickett slide rule and left the chemical engineering field, but, as I now recall, finely crushed coal takes on an almost liquid character, and has identifiable flow characteristics. In the late 1970s, producers were looking seriously at coal slurry pipelines as an alternative to rail transport. Coal may not be that difficult to utilize. <br /> <br />Best regards, Michael Sol <br /> <br />[/quote]Somebody had or designed a turbine that ran on powdered coal, I'll go look it up and tell you about it later.
