<DIV>Thanks for jumping in. I found your previous stuff and suggest all go to
the Unity Stove site for a catchup</DIV>
<DIV>Ksial seems like good stuff. I have to import everything any way so
importing Ksial would be no worse.</DIV>

<P class=MsoNormal>Hi All,<o:p></o:p></P>
<DIV>
<P class=MsoNormal>I've been reading this list for a while and thought it
was about time I introduced myself and the work I have been
doing.<o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><o:p></o:p> </P></DIV>
<DIV>
<P class=MsoNormal>I am Thomas Hastings from Australia and have been doing
the citizen-scientist and design, prototyping and testing work that it seems
many people are doing to help reduce emissions and improve the life and
health for the billions who cook with solid fuels.<o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><o:p></o:p> </P></DIV>
<DIV>
<P class=MsoNormal>My background is in Industrial Design and my "day job" is
design and managing the production of retail displays. My passion is for
cookstoves and the geopolymer material I have been
developing.<o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><o:p></o:p> </P></DIV>
<DIV>
<P class=MsoNormal>As I designer, I know how much the cost of material in
today's manufacture with super low labour costs (well relative to Australian
labour costs) affects the end cost of production.<o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><o:p></o:p> </P></DIV>
<DIV>
<P class=MsoNormal>FeCrAl alloys or stainless steels are expensive and
always will be. They can only be produced in capital intensive factories and
the pricing is mature and well developed.<o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><o:p></o:p> </P></DIV>
<DIV>
<P class=MsoNormal>I have pursued a material class that could be, in volume,
produced at a cost comparable to cement. There is a lot of work going on to
develop Geopolymer as a replacement for OPC in building construction. It is
very close nowe, its out of the lab and buildings have been
made.<o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><o:p></o:p> </P></DIV>
<DIV>
<P class=MsoNormal>The material developed by Unity Stove is a bit different
to but similar to these Geopolymer construction materials. It does perform
exceptionally well in cookstoves and does not crumble like cement. It can be
moulded easily and unlike fired ceramics, reinforcing and insulating
materials can be incorporated. <o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><o:p></o:p> </P></DIV>
<DIV>
<P class=MsoNormal>We have made prototypes stoves to show how a stove could
be made. Whilst the Unity Charcoal Stove you will see works very well, the
Unity Stove concept is actually a material and method for making stoves
using low cost tooling to many designs. <o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><o:p></o:p> </P></DIV>
<DIV>
<P class=MsoNormal>Whilst I could talk about this for another twenty pages
it may be best if you have a look at some videos for a quick into. Hopefully
you will see that high performance stoves can be made locally and at minimal
cost<o:p></o:p></P></DIV>
