-274 is 1 degree below absolute zero (-1K)... thats why!
cascades have hit nozzle temps of around -161.8C (cold_ice's 4 stage @ 111.35K), which is only 36 degrees above the boiling point of nitrogen (-195.8 = 77.3K)... nitrogen is quite cheap (much much cheaper than building a 4 or 5 stage cascade to achieve the same temps) because of its abundance in the atmosphere, however, it can barely hold a load (which is why it evaporates so quickly) and is not feasible for 24/7 cooling
