Re: I wonder what the skiing is like!
“Now, you didn’t get much in-suit training Earthside. We didn’t want you to get used to using the thing in a friendly environment. The fighting suit is the deadliest personal weapon ever built, and with no weapon is it easier for the user to kill himself through carelessness. Turn around, Sergeant.
“Case in point.” He tapped a large square protuberance between the shoulders. “Exhaust fins. As you know, the suit tries to keep you at a comfortable temperature no matter what the weather’s like outside. The material of the suit is as near to a perfect insulator as we could get, consistent with mechanical demands. Therefore, these fins get hot — especially hot, compared to darkside temperatures — as they bleed off the body’s heat.
“All you have to do is lean up against a boulder of frozen gas; there’s lots of it around. The gas will sublime off faster than it can escape from the fins; in escaping, it will push against the surrounding ‘ice’, and fracture it … and in about one-hundredth of a second, you have the equivalent of a hand grenade going off right below your neck. You’ll never feel a thing.
“Variations on this theme have killed eleven people in the past two months. And they were just building a bunch of huts.
Come to think of it, the suit doesn't need to be an insulator except for the boots, but you have to get rid off the body heat indeed. Best would be to scoop up some ice and make it gas out, taking the heat with it, right?
