Yeah etharp, I do agree..........if you have a beer you allways drink all of the glass! So I know what you are getting at. Lets not go to carbon pile just yet. I still does not get around the point that we as an industry don't seem to have any comparisons between the 2. So what would happen if we ran the very best in DC technology against an AC machine? lets say both trucks are the same model, same lift height lifting the same loads, same battery, clone 2 drivers :), it does not matter who the manufacturer is. By the way this question came up in the office...........asked by a sales person! His customer is asking for this information so he can show his suppliers what he is doing to reduce his carbon foot print. I guess he wants to use it in a BSI audit for some of his energy reduction figures.
