 It was really the requirement of this this this large door because Yeah, because sentiments they were building wooden doors and sometimes metal doors and it's just of the fact that this had to be a very large door in metal that Created really that's where art phantom and had to you know put his mind To to something's very special that would would accommodate this requirement, so this really goes back to the door Requirement again, that was a challenge, but as I mentioned earlier The The trident system is very adaptable. I mean the very first time was a door But then now we are getting involved with structures in the north for permafrost applications So that's another The the it seems like we're always finding new opportunities to apply the product in Different aspects that we would never have thought of at first. Can you talk a bit about the most recent solutions? Sorry problems and then solution. Yeah, such as permafrost Yeah permafrost applications actually stemmed from There was the National National Research Council of Canada We're looking into different foundation systems in the north because permafrost is an ever-changing Soil condition it could be frozen one year and not so frozen and now with climate change There is softening of permafrost which means some of the buildings that were Previously sitting on frozen ground are now on soft ground and are cracking So the National Research Council were doing some research as to what how can we get around this problem? And they knew that we were able to build Space frames. So this is would be like horizontal structural systems and They felt that if they could build a building on three points Then you have a stable system because three points is the most stable condition you can have so they they contacted us to build a flat space frame and put it on three points So it could be built in the north. So we built that and It was successful. It worked very well, but I saw a limitation in that it would Probably not we could not make very large structures Because if you build very large structures on three points, that means you have only three points of support Which also means you would have very large forces on the ground In a ground condition that is poor. So that Intuitively that didn't work as far as I'm concerned. So I Felt why don't we put that whole slab onto multi points like have every component all the joints are Sitting on the ground on plates. So it's like a more or less like a floating slab sitting on many many points and So that was tested as well and it had great results Because in that case you wouldn't just have three you'd have many points But to be the let's say if a space frame had a hundred base plates Not all hundred need to sit on the ground. You could have some floating as long as you have enough rigidity within the system So that has become now for us in triadic. That's that's become a really interesting application and we have used This system now in Russia in Norway. We're in Alaska. We're in northern Canada so it has the permafrost Which is now because of global warming is becoming softer Our applications are actually expanding the use of it is expanding Right and you've it makes it a lot easier also to even move or relocate houses That's right because you could pull it away. You could actually drag it and In Shishmaref Alaska There are several This is in town has been there for hundreds of years and it's on the coast of the Chechi sea and The Chechi sea is eroding the coastline and some of the buildings are actually fell into the into the sea So we went in there some years back to take measurements of the existing buildings that are on the edge of this cliff and We lifted the building put a triadic underneath and Put our triadic structure on skis like metal Ski and then waited for winter and we pulled them with bulldozer. We slid them a kilometer away and We did I think some 28 of these these homes and there is another neighboring community that has the same issues Don't recall the name, but we're now working with that community to Move them also away from the shoreline
