I ran across this blog entry by virtue of my pastime of science fiction:
How Long Could Luke Survive in a Tauntaun?
On the Zeray Gazette: i.e., locustsandhoney.blogspot.com
As a mental exercise for those inclined toward natural science, zoology, hunting, or even simple thermal dynamics, this is interesting. Obviously the scenario is entirely impractical, involving invented creatures and speculative worldscapes from Star Wars, and yet I found it refreshing (i.e., fun) to read. "Hard SF" appeals to me.
