assistant: Day,
 The very first steam engines had a piston that was several FEET in diameter,
and were used to pump water from coal mines in England. Speed was only a few
strokes per minute; the earliest ones had MANUAL valve gear.
And they worked at '0' PSI steam pressure.

assistant: Hi Day
On (02 Sep 97) Day Brown wrote to Alec Cameron...
Remember in my reply, I mentioned the steam liner "Great Britain"? The
designer/ builder was Isambard K Brunel. He designed and built a railway
called the Atmospheric Railway in the south of England. Bits of it have been
preserved. 15psi, and leather! were primary elements in the locomotion
arrangements.
On the assumption that steam at 15psi wouldn't be very hot, I guess the
leather could be OK. It might help to laminate the leather with an open weave
polyester netting, to give it hot tensile strength.
But I'd rather talk about Brunel!!
The atmospheric railway ran on a vacuum tube laid between the rails. The ties
were lengthways instead of cross from rail to rail. The vacuum tube was
slotted on top and the slot was sealed by a continuous leather flap.
Vacuum was held by trackside pumping stations.
The lead car of the train had a piston underneath, the piston travelled thru
the vacuum tube and the thrust was provided by the driver's controller- a rod
of some kind would push the vacuum tube leather sleeve aside so as to admit
air to the desired side of the piston.
Thus the train was propelled by air pressure [15psi]. Neat. It worked.
OK, it worked but there were problems. I imagine it would be tough to shunt
n
a busy depot or junction, 'cos one train moving would slow down any other
nearby. Collision protection? ;-).  More important by far, the rats loved to
eat the leather which [I think] was smothered in lard [edible] to improve the
sealing.
The system was not a hilly one, and I am sure it was for passengers only.
Isambard K Brunel was a practical engineer, many of his great achievements
re
still in everyday use and he was not driven by Managers or Bean counters!!
And, he was not familiar with the appetites and tastes of rodents.

Seemingly it converts the rust into some sort of inert metal and bingo end of

LOYS I seem to remember seeing a piston of similar dimentions when I was at
trade school. Well, two actually, one was from a water pumping station and
the other was from a marine engine. Apparently the marine engines all had
individually cylinder blocks so if (as in the example at trade school) they
crack a ring and score the bore badly they can be replaced virtually in situ.

assistant: "0" can be measured. If you have "0" PSIG, then you don't have steam. Now
pressure measured in inches of water column, (in.W.C.) is a different story.
Takes roughly 27.7 in.W.C. to equal 1 PSIG, so even 5 in.W.C. spread over a
large area will yield significant force. Force being pressure applied times
the surface area feeling the pressure. Quick calculation in the head gives
around 18 PSIG for a 5 in.W.C. pressure applied to 100 sq. in. surface area.

A wise move, diesel fuel having high energy efficiency and the engines being

Of course if exotic aircraft are not too far off topic, there have been real
man carrying vehicles propelled by solar panels, bicycle pedals and even
team
engines but none of these became "commercial". Like with HOMEPOWER, the
lower
you go the further you get and the idea of modern ocean freighters driven by
sail can have its parallel in aircraft [slow] having substantial gliding
ability and a minimum of engine power. All this rushing about is very bad
