Also, the fact that if you boil water inside a house that is being heated saves the heating fuel so it is effectively free if the fuel is the same (gas stove for example).<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The test runs that others performed to try to replicate results are smudged by the fact people are crossing the boiling point. They are trying to calculate an engineering efficiency while performing an arbitrary task, simultaneously ignoring one of the metrics (the energy put into water that is somewhere between 100 C water and 100 C steam). Naturally the results are randomly affected. There is a good lesson there!<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Regards<o:p></o:p></p><p class=MsoNormal>Crispin<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
