First, that energy is not being lost. It is inside the system and sooner or later it comes out in the form of a hot gas, probably preheating the gas before the flame. Second, aluminum would melt in there. If you radiated it at the dome from below the dome would only get a little hotter and you would be cooling the system somewhere else.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>If the heat was getting away from the stove completely that would matter.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Regards<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Crispin<o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'>Crispin,<br><br>You've seen the video of the dome that is red hot.<br><a href="http://www.youtube.com/watch?v=80REBVTwpMo">http://www.youtube.com/watch?v=80REBVTwpMo</a><br>The dome emits radiant energy in all directions.<br>I placed a shield on the sides of the dome to stop the lateral loss of radiant energy.<br>You can see the shield clearly in the video.<br><br>But there is a lot of radiant energy (perhaps half) that goes down to burner and does not heat the pot.<br>I want to put a piece of tin foil about 4 mm above the burner.<br>If it does not touch the burner, it should be more reflective.<br>The idea is to reflect radiant energy back up in the direction of the pot.<br>Does this make sense?<br>What difference should this make?<br><br>Paul<o:p></o:p></p><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>On Tue, Mar 6, 2012 at 4:27 PM, Crispin Pemberton-Pigott <<a href="mailto:crispinpigott@gmail.com">crispinpigott@gmail.com</a>> wrote:<o:p></o:p></p></div></div></body></html>
