[TheForge] coal or charcoal

[Peter Hirst]

Dave:  I'm not looking at biodiesel yet:  the process is too complex, 
although I am fairly sure it would work.  More precisely, I have looked at 
it and determined that its too much to take on for the volume I need: 
couple gallons a week

I am looking at filtered waste veggie oil -- what the Greasecar  runs on --  
first,  I just need to determine whether the heavy stuff in wvo will tend to 
polymerize , or just plain thicken like like paraffin oil, which is what 
blocks tubular wicks in center draft lamps.
