Late to the discussion, but I just have to say that I lose all suspension of disbelief when marketeers get their units wrong. What is it, 7 watts, or 7 joules? A watt is a unit of power, a force times a flow. A joule is a watt*second, a unit of energy. If it generates 7 watts instantaneous, a footstep would have to last a full second for there to be 7 joules. I suppose the next thing they'll claim is that when my 6 joule fence charger knocks me off my feet, I'll generate 7 joules, as long as I land on Pavegen. :-) Units demystified, for those interested: http://www.ecoreality.org/wiki/An_energy_primer :::: If you can't be a good example, then you'll just have to be a horrible warning. -- Catherine Aird :::: :::: Jan Steinman <http://www.EcoReality.org> :::: _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
