<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Certainly a "Closed Loop" or "condensing system" is more
efficient than an non-condensing system. </FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>While the steam engine may not require Certification,
boilers do, depending on the rules in a given Jurisdiction. While it is
certainly possible to operate a steam boiler "in a back woods location that the
Boiler Inspector doesn't know about", The Boiler Inspector will find out if
there is an accident where someone is seriously injured or killed. </FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Steam can kill.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>If anyone is considering a "Steam Application" they should
check with their Boiler Inspector, to confirm that he would be able to
approve the Proposed Project.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Best wishes,</FONT></DIV>

<DIV><BR></DIV>Hi Kevin, <BR><BR>Thanks for the lesson. Spent a little time
googling and wikipediaing. I may have a slightly better grasp of the topic
now.<BR><BR>I did find something which may be worth looking at: <BR><BR><A
href="http://www.greenturbine.eu/en/product.php">http://www.greenturbine.eu/en/product.php</A><BR><BR>These
appear to be self-contained turbines with a closed loop steam/feedwater
condenser system at 1.2, 2.4, and 15 kW. Steam is supplied at ~5 bar and the
condenser side is ~.1 bar. They sell primarily to systems integrators, one of
which makes a CHP wood pellet furnace w/cogen. (<A
href="http://www.greengen.be/">http://www.greengen.be/</A>) I wonder if they
would sell to APL and/or if APL would have any interest in making a steam
turbine genset...<BR><BR>Bryce<BR>
