Really? I think that it proves the point that we are all trying to make about coal. It's cheaper than oil. When I bought this house years ago and told people I burned coal they looked at me as though I was a moron. Not any more.
This is proving to be, like other threads that Larry has started, a nice, lively round-table on coal burning. Taking cheap shots at him and his intelligence is uncalled for and certainly not in the spirit of this site. When he designs the first 100% efficient coal appliance that heats a wind tunnel on 5 pounds a day we're all going to line up to buy one.
