Federal regulations can be maddening, but none more so than a current one that demands oil refiners use millions of gallons of a substance, cellulosic ethanol, that does not exist.
 

"As ludicrous as that sounds, it's fact," says Charles Drevna, who represents refiners. "If it weren't so frustrating and infuriating, it would be comical."
