THE ROCK SOCK In order to more fully understand the relationship between energy and camping I tracked the movement of energy while on a camping trip. I found that there were a variety of activities and objects that consumed or re-purposed energy. I also found the places where there was excess energy that could perhaps be reused. Through this research I found an opp0rtunity to reuse energy from a campfire to heat personal spaces.

Product Summary The Rock Sock is a simple safe solution for holding a hot rock pulled from the fire. Just a 1 pound hot rock will release half as much heat as the human body over a six hour period. Perfect for some added warmth in your sleeping bag.
