Love watching the train progs on Discovery and how the Welsh trains were the inspiration for those in America. Just a technical point. Water to steam is just a way of producing a gas under pressure, rather than having cylinders of compressed air. What volume of steam is produced from say, one gram of water? Are there other liquids that produce large volumes of gas from a liquid -- mercury perhaps?

Probably, but water is cheap and it doesn't matter much about the waste product venting.
It would probably turn out that it is the ideal medium - doesn't water have some odd properties at boiling point due to h-bonding and such?
Now with mercury that would be different!

Well now, let's see- I' m sure I could have answered this when I was at Uni; Gay-Lussac's Law, or was it Boyle-Mariotte? PV=nRT?Originally Posted by johnep

Translation please. Have heard of Gay-Lussac but not the other fellow.

Looked both up and the latter is simply Boyle's law. Wiki gives 1ml water = 1,600mls steam. So now I know. Just wonder if any other given mass gives larger volume.

My car is 1600cc so would require 1ml water per rev. At 2,000 rpm would consume 2ltrs a minute. Wonder what a Stanley steamer would do to the gallon of water.

Why not try some Stirling engine experiments in your retirement.
These engines are fascinating.
I'm wondering if the temp difference between the living room (20C and outside -6C) is enough to do any useful work?

good question - should be levelled at the local authorities too! (sir_nothadhisbinscollectedfor6weeksalot!)

Seem to remember Hart Davis prog on a Stirling engine using couple of old CDs. I feel a google coming on.
