[modeleng] Re: scottish inventions

Newcomen's engine was not an actual steam engine if I recall correctly.  His 
idea was to draw in steam at atmospheric pressure, seal it in the cylinder 
and then cool it so it condensed and formed a vacuum which then pulled the 
piston and raised the pump rod in the mine

Jesse, the Tennessean with the last name of Livingston which is lowland 
Scot.

I believe that Watt made the improvement ot Newcomen's engine, by fitting
 the separate condensor, thus saving a huge amount of fuel.    Newcomen's
 first successful engine worked in 1712.

 Watt and Boulton produced a successful engine with a condensor in about
 1773.
