1:33:28>> And you know we think that okay maybe this can be fixed by snow making right maybe we could just artificially make all the snow that we ever need. That's not even going to work either because even snow making works at an ideal temperature right you need to be lower than the due point which is when the snow that you're putting out is not going to condense into water droplets. Right? And so it's you've got to be below -2 degrees C, 28 degrees Fahrenheit. I mean, depending on the pressure, but usually and the humidity, but usually that's about the the temperature. Now, that's really bad because we've covered a story on this podcast before about how the world mountains are warming up faster than the plains because hot air rises and so on and so forth. So, we have that um we
1:34:10have that little tidbit that the mountains are actually warming up. >> Yes. So all of these factors are combining to make it really really quite problematic to do winter Olympics in the same places that we used to be able to do. >> Right? People are suggesting that they can do something called snow farming, which is a new thing. I don't know if you've heard about this. I didn't even know this was possible. You you get a bunch of snow and you pile it up with massive piles of sawdust, tarps, and wood chips, and that retains 60 to 75% of the snow.
