well... if youre in a pinch.. and worried about 'solar' energy
head on down to center camp, in front of the cafe, find the cauldron.. diablo.. some years they succeed in lighting it using the sun, they did this year in 2011
theres usually wood around somewhere near to keep this flame going all week long...
stoke that fire, throw on a log and start cookin.
thats good heat!! dont waste it..
