But economically? Fork lifts are an order of magnitude less powerful and less expensive. You'd need a half-dozen pack swaps to get through a 12-hour day. These are going to be ~600 kWh packs for a ~400 hp tractor! Doesn't that about quadruple the total cost of already-expensive machinery? I'm not saying it's impossible. But it's going to be a huge challenge. One thing's for sure: with 600 kWh packs, the days of wheel weights and calcium in the tires would be over. :-) Jan _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
