This one used some special electrode treatments to get more power than normal. In the end, for total watt-hours, it all comes down to what reactants you're using, and their mass. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
