That saves the effort of waiting for it to dry. You know, I like Rok Oblak's drying of fuel on the outside of the stove. That helps the lazy accomplish something else while loafing. </div>
<div><br></div><div>I am picking up Jean-François' comment about the claimed performance for the Envirofit stoves, i.e that they are modest. Well, isn't that better than exaggeration? </div><div><br></div><div>I spent many years designing production equipment for small industries and a production claim has to go with each system. They are run by ordinary people who learn on the go. What worked well was based on 6 hrs per day of applied effort. After 4 months our estimates were usually exceeded. So if you claim a performance that everyone can achieve after a month or so it leaves most people happy. </div>
<div><br></div><div>As you can see most products they showed are some iteration of a Rocket Stove which typically has an efficiency of 27%. The big difference is durability from what I can see. Funders want 5 years now.</div>

<p class="MsoNormal"><font face="Arial"><span lang="EN-GB" style="font-size:10.0pt;font-family:Arial">Jean-Francois, bon jour à la France d’Allemagne!</span></font></p>

<p class="MsoNormal"><font face="Arial"><span lang="EN-GB" style="font-size:10.0pt;font-family:Arial">It is necessary to continue somehow the line you draw
in your posting in that thread.</span></font></p>

<p class="MsoNormal"><font face="Arial"><span lang="EN-GB" style="font-size:10.0pt;font-family:Arial">We must consider that laziness (e.g. and especially
in preparing fuel) will be our most useful helper in acceptance of a stove.</span></font></p>
<p class="MsoNormal"><font face="Arial"><span lang="EN-GB" style="font-size:10.0pt;font-family:Arial">Wez would best construct CO2 neutral-stoves even for
use (and with acceptance) in “lazy-advanced” countries.</span></font></p>
<p class="MsoNormal"><font face="Arial"><span lang="EN-GB" style="font-size:10.0pt;font-family:Arial"> </span></font></p>
<p class="MsoNormal"><font face="Arial"><span lang="EN-GB" style="font-size:10.0pt;font-family:Arial">The law of minimal resistance applied on humans is
simply called “laziness”; and that is a law of (all the) nature.</span></font></p>
<p class="MsoNormal"><font face="Arial"><span lang="EN-GB" style="font-size:10.0pt;font-family:Arial"> </span></font></p>
<p class="MsoNormal"><font face="Arial"><span lang="EN-GB" style="font-size:10.0pt;font-family:Arial">The conclusion is the need, to construct stoves which
burn (mostly) un-split and un-chopped wood, -even when small wood would burns
far easier.</span></font></p>
<p class="MsoNormal"><font face="Arial"><span lang="EN-GB" style="font-size:10.0pt;font-family:Arial">The stove has to get quickly and brightly to burn
without work; even when it has to burn later-on big logs. </span></font></p>
<p class="MsoNormal"><font face="Arial"><span lang="EN-GB" style="font-size:10.0pt;font-family:Arial">The nearly unreachable laziness-model is a
bottle-gas-stove. </span></font></p>

<p class="MsoNormal"><font face="Arial"><span lang="EN-GB" style="font-size:10.0pt;font-family:Arial">If we want to work with wood or something likely we
will be forced to work with hybrid-stoves, if we want to create stoves for
lazymen/lazywomen.</span></font></p>
<p class="MsoNormal"><font face="Arial"><span lang="EN-GB" style="font-size:10.0pt;font-family:Arial">- A T-LUD, started with a gas-torch is likely the
same, without being the method of choice.</span></font></p>
<p class="MsoNormal"><font face="Arial"><span lang="EN-GB" style="font-size:10.0pt;font-family:Arial">Dealing with wood-like fuel we will have to think
always about a “fire-cascade” to get a stove quickly started and
without much splitting/Chopping-work.</span></font></p>
<p class="MsoNormal"><font face="Arial"><span lang="EN-GB" style="font-size:10.0pt;font-family:Arial">Dealing with different-shaped fuel/wood the stoves
must be different; e.g. rockets, T-Luds, saw-dust-stoves, etc., but all
hybrid-stoves to deal with laziness.</span></font></p>
<p class="MsoNormal"><font face="Arial"><span lang="EN-GB" style="font-size:10.0pt;font-family:Arial"> </span></font></p>
<p class="MsoNormal"><font face="Arial"><span lang="EN-GB" style="font-size:10.0pt;font-family:Arial">Since some months I am thinking about
fuel/wood-pre-warming to facilitate that “fire-cascade” .</span></font></p>
<p class="MsoNormal"><font face="Arial"><span lang="EN-GB" style="font-size:10.0pt;font-family:Arial">Some “hand-held” experiments by starting
my space heating stove gave me courage to look further.</span></font></p>
