Where you have excess energy that would otherwise not be utilised, then even a low efficiency storage system can make sense. It still makes more sense to use a more efficient storage technology if the technolgy costs are comparable. Redox batteries for example. -- Paul Compton www.morini-mania.co.uk www.paulcompton.co.uk (YouTube channel) _______________________________________________ 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)
