<p class="MsoNormal"><span style="mso-fareast-language:EN-US">I think your point is well made. LPG is not safer than ethanol, and can be burned just as cleanly (if the device is properly designed).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">You are using an alcohol mixed with water in high proportion. Are you heating the water to release the ethanol and leaving the water behind? If not, do know if this has been tried?

<p class="MsoNormal"><span style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">An approach taken by several manufacturers is to use a solid, porous sponge as a retaining mechanism. I happen to have worked with a version of this. It definitely works as an accident preventing
mechanism. The only problem I found was that designers felt that ‘alcohol is a clean fuel’ and didn’t put much effort into the combustor to see that it really was clean-burning.

<p class="MsoNormal"><span style="mso-fareast-language:EN-US">Similarly there is a methanol stove producer in Africa that developed a vastly superior version of his product by using a contextual development test. That product went from an under-powered and
smelly burner to a powerful and extremely clean one and is now in production. <o:p>

<p class="MsoNormal"><span style="mso-fareast-language:EN-US">At some point in the past I was approached by a sugar mill looking for ways to use about 100 different types of alcohol that were distilled from their ethanol plant. Surely you also have access to
these dregs? I never had a chance to work with the dregs so I don’t know what lovelies came from a good or bad flame. Maybe you have some experience with that.<o:p></o:p></span></p>
