Instead, the researchers suggest future work along similar lines might control how matter behaves in other ways, such as reducing drag on surfaces, preventing the formation of frost or ice, and efficiently transferring heat via boiling and condensation.
This page is missing two images of charts and several paragraphs relating the continuous film of vapor mentioned above to the behavior of materials sliding on snow. To be continued.
1/14 Recently had some discussions online with mushers about optimum runner width for different conditions. They were correct interpreting the second graph below to indicate there is a “sweet spot” for lowest drag but where it exists is contingent on temp, snow condition, load, speed, etc. as listed below the graph. So, runner width is also a factor. However, they used the word and concept of flotation to characterize the effect of runner width, which is misleading. Better to think of packing snow. Since the snow does not respond like an elastic substance, more likely a narrower runner will be doing less work, packing less snow and causing less drag.
