   Don't let's forget that the operator of a steam locomotive was called,
   and was, an "Engineer."  It took a lot of learning to be able to ride
   herd on all them busy molecules, and even then, the stories of boiler
   blowups are legion.  You need a special ticket just to operate a steam
   heating plant in an apartment building, and with good reason.  Steam
   anything needs to be safetied and and carefully watched.  Not a
   particularly good choice for "part-timers."  While ma's changing the
   baby, and pa's chopping firewood or doing the chores, the pressure
   gauge can be doing a 360.  You got injector pumps, by-pass valves,
   pressure gauges, level gauges, temperature gauges and a lot of other
   stuff that needs attention all the time.
   I'm a big fan of steam, but it's got my respect, too.  It doesn't run
   on automatic like your basic Honda generator......
Best, ps
