'William Chops" Westfield ' A human is supposed to be "about 100W" at normal (in)activity levels. I thought it was more like 30W. I remember seeing various human activities rated in terms of Kcal/hour. Just sitting around was rated at 25 Kcal/h, which is about 30W. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
