<!Please do not trust these values given thru this program (i'm just an interrested amateur) - You have to proof it by yourself - maybe You can use the structure of this program for Your own calculating code>


<! Thanks to Alan Altman for his description of his comprehensive stirling analysis tool, which inspired me, too. Highly recommended: http://snapburner.home.comcast.net/index.html>
<! Thanks to Koichi Hirata for his theory of stirling analysis for alpha, beta and gamma engines>
<! Thanks to Lutz Tautenhahn, who gave me an idea how to create a diagram in html-files>
<! Thanks to Sesusa (Yahoogroup), who helped me to solve some of my understanding problems easier and faster>
<! Thanks to Mr. Urieli, whose internet pages with information improved my knowledge about stirling engine analysis>
<! Thanks to all people, who inspired my thinking - hopefully for a better and environfriendly world for all of us>




<! to do  >
<! diagram - improvement: scales and cleaning source code, Html5 canvas?>
<! clear visible structure: input, calculation, output>
<! .hta and .htm "compatibility": usage of clipboard (ie?), instead of saving values into files, printing array values into document(.open()), forward and back button? possible?)>
<! change between inch and metric system should change values too! (calculating with Si-units and their derivatives)>
<! testing on netscape and opera browsers and linux system>
<! gradient following optimisation (GRG, SQP, Newton/Raphson, etc.)? >
<! maximum energy output - testing of all possibilities>
<! alpha, beta, gamma hirata (sinusoidal, ross yoke) formulas for adiabatic, simple analysis
<! Manson, LaminaFlow?>  
<! Zig Herzogs analysis theory - comparing outputs>
