[DL] Re: Steam needs water

[Michael Robert Blair <pellinoire@yahoo.com>]

You make a very important point about steam engines
need for water.
You will need a lot of water unless:
1. You have condensors - which will add weight and
volume and you will still lose steam from leaks,
whistles, etc.
2. It is a ship and can distill fresh water from salt
(historically this took a while coming, early marine
boilers used salt water - with horrible corrosion
problems).

I don't know much about steam trains but I have the
impression they stopped for water more often than
coal.
