wannabe... although a lot of people would tell you to finish your education first, that's something that only you can determine. that said, contact the companies listed previously on posts here on this thread. they are the main players in the fueling business. i would also add combustion engineering to the list, along with their subsidiary companies. but it's a good way to see the country and even the world, once you get your feet wet (so to speak, not literally).
as far as no new plants being built, snowman better get his reading glasses on. the last list i saw had 15-20 plants to be built domestically in the next 20 years. these were only the ones listed for cols and such. there will be more. it's a great time to break into the business, especially as the esteemed pwhoppe pointed out the current work force is graying rapidly. so if you can do old-speak, you'll go far.
