[Gasification] sexy steam

[Bob Stuart]

The notion of running a steam engine in conjunction with Internal  
Combustion comes up frequently.  Usually, there are two problems.   
One is that the scheme produces low-pressure steam, so it is barely  
worth the effort.  The other is that it seldom produces much steam  
for one very simple reason.  Look at an old steam locomotive.  Big  
Firebox, Huge Boiler, Tiny Cylinders.  It takes about 11 sq ft. of  
boiler tube area per HP, with a dedicated fire.
