Yup, boiler inspections are required, it's what killed steam heating,
which is much more efficient and requires far less internal space than
ducted air. Well, that and the clanging, water hammers and the
opportunity to be scalded to death in your own apartment. .
You can build a very efficient steam engine, but you still bang up
against the carnot cycle. And air-cooled steam engines hit that wall a
lot sooner than water cooled. Still, they make a lot of sense for
cars, especially in a hybrid approach where warm-up wouldn't be such a
problem. Single speed steam engines can be much more efficient than
variable speed ones--they make great generators, which is one reason
steam turbines are the default generator prime mover. They require
complex water removal systems to ensure the steam has no entrained
liquid--it eats the blades up like a sandblaster. But that's ancient
technology.
I've been reading a lot of popular physics books lately (that sounds
like an oxymoron) and I'm struck with how many good ideas have been
squashed by "fashion" in science. You don't have to be a quack to have
your career ended by supporting a discredited theory. Just ask Pons
and Fleischman (Cold Fusion). Interesting that all these many years
later (15) the department of Energy convened a second review panel
(2004) to look at chemically influenced nuclear processes. The area of
study has been deeply compromised by the public mania and resultant
backlash in the scientific community. Fashion, in other words.
It doesn't take a conspiracy to doom promising technologies, all
that's necessary is plain old human self-interest and herd mentality.
