Dear Tom 

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

  I checked the name and you are correct – recent too.

    Hi All,

    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.

     

    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.

     

    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.

     

    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.

     

    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.

     

    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.

     

    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. 

     

    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. 

     

    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

     

    Thank you,

     

    Thomas Hastings
