You have this exactly backwards; we use evaporating sweat as a homeothermic mechanism, other animals have to rely on panting and radiation. As a result we are one of the only animals able to perform work at high temperatures. If you want to see this in practice take your dog for a run on a cool day. It will take 3-4 hours before you will begin to outpace him/her. Do this again with the temperature in the mid 80s. It will now take you about 15 minutes to leave it in the dust.
Regarding dehydration, every glycogen molecule binds 3 water molecules. Burning glycogen for energy produces free water for sweat that does not need to be replaced until the glycogen store is replenished.
Interesting? Surely you meant funny. I mean considering the link goes to a story on the main page that describes the space chariot and suggests that it sounds like a Stephenson story.
