Hi I am Jason, finalist in the Popular Mechanics sponsored Wood Stove Design Challenge. It will be my first visit to North America for the November challenge in Washington DC, and getting there itself will be a challenge. You will see from the list of entrants that the IntensiFire technology is a retrofit which means I need a wood stove to modify. Can you help with one? If you can help me with a stove for the duration of the challenge then the bonus for you is you get back a highly efficient clean burning stove. There are a few requirements though, the first is that it is best if it is no longer in production, or the rights to the brand not still owned. The rules state that there must be approval from the manufacturer to use the stove in the challenge. If you are a manufacturer and are happy to supply and old model then I would be glad to hear from you. On the technical side I am looking for a top exit flue of 6" or 150mm diameter. The core of my technology is a flue extension inside the stove, so any baffles or obstructions need to be easily removable to achieve this. I have found that a North/South design does have some advantages, but I will take an East/West if it is on offer. If you are in Washington DC and have the means to move a wood stove then I would like to hear from you as well. FYI to ship one from New Zealand would cost around $2000 NZD, so a local source is the way to go. I will also throw in the mix a request for accomodation in DC for myself and my retired father(he is paying for the flights). Plan at the moment is to find a hostel in walking distance to the National Mall.
