Yup, People have a big "foot print". But that is a whole 'nother discussion, except that with renewable energy powering the transportation, I am able to reduce my foot print and I chose to do that using an EV and buying green electricity...

The only really not-crazy practical use case I can think of for a solar EV is for a nomad who's not in any type of a rush to get from one place to another. (Of course, they make great project challenges, especially for engineering students -- but they don't try to pretend that the vehicles are useful general-purpose vehicles). ...and, even if you <i>are</i> the nomad type...you're probably still better off with the panels stowed away when driving, and setting them up as a tent-like structure over the vehicle when you've settled down for a couple days while you recharge for the next few hours of driving. Come to think of it, even that isn't exactly practical, either. You know...there's another way to look at it. All life (within rounding) on Earth is solar powered. Plants, obviously. Animals eat the plants. Consider the acreage needed to sustain a person. People are very small and low power objects compared to high-speed vehicles. b& _______________________________________________ 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)
