    <br>
    Your experiences are highly interesting.  Let's review the situation
    (as far as it is known from the messages).<br>
    <br>
    You have been using a homemade TLUD stove for less than one month. 
    And you use it inside a room that is sufficiently enclosed that any
    emissions must exit through a window.  You are in China, and the
    past month with stove usage was a November.  Most of China has
    reasonably sealed housing to keep out the winter weather.   You are
    not an experienced user of TLUD stoves.  And we do not know what
    your are using as fuel.<br>
    <br>
    NOBODY should be using ANY Do-It-Yourself stove in such a
    situation.  In a reasonably sealed residence, nobody should be using
    any biomass stove indoors without an adequate chimney.  <br>
    <br>
    I am glad that you did not die or suffer permanent damage.  I have
    never before asked anyone to stop working with TLUD stoves, but I
    suggest that you stop.  <br>

                      <div>TLUD stove is efficient but fragile. this

                                                1500RMB (230 USD), in
                                                rural area, a big
                                                number, very big, no one
                                                buy, not even one, in
                                                rural area. For user,
                                                many uncertainties to
                                                use new type of stove.

                                          I was wondering about the
                                          price of that pellet burner
                                          stove.  Yes, it is expensive,
                                          but expensive is a relative
                                          term.   It could be imported
                                          into America where $230 is
                                          inexpensive, but the price
                                          here would be so much higher
                                          and it would then be expensive
                                          here.  <br>

                                          Is there any prospect in China
                                          for DIY.   And what would be
                                          the acceptance of a stove made
                                          with thin metal?  
                                          Generalizing, it seems that
                                          heavy construction of stoves
                                          is the standard in China.  
                                          Todd Albi might be able to
