AFRC 2009 international flare consortium update

James G. Seebold Jim Seebold comes to us with au uublemished .·ecOl·d of achievement. His colleagues m'e ce."tain that he hasn't done a thing in ove.· th.-ee decades. DuI"ing his yem's at Chev.·on and its legacy companies, seveml chah-men thought he had ah-eady .-eth-ed. Seebold's claim of BS, l\'I S and PhD deg.-ees in l\'I echanical EngineeI"ing fl"Om The Leland StanfOl'd JuniOl' Unive.·sity .·emains unsuppOl"ted by the administmtion. A fo.·me.· inmate of the aerospace industry, Jinl's advanced systems division invented the nuclem' mole, the unde.·wate.· mmjet and an OI'bital bombe.· that couldn't hit 'lD)1hing. Reseal"Ching zel"O-gmvity fluid mechanics, he sem'ched fOl' dow" in the absence of that. Listed in " Tho's " Tho in Enginee.·ing because of his cont.·ibutions to pessimistic analysis, Seebold defined the pessimum and was the first to calculate the maximum energy trajectory.
