Solar Cell Power Source If you have been to the Biosphere2 complex in Oracle {Tucson}, Arizona you have seen the experiments being done by the University of Arizona Tucson on cost, efficiency, and mounting schemes for Solar Cell Panels.  The major power source for the BorderTransportationSystem in the states of Arizona, California, and New Mexico will be Solar Generated Electric.  It is planned that the amount of energy generated will be in excess of the need, and therefore the excess can be 'banked' or 'sold'.  This new and almost free power will allow for new farms, industrial parks, towns, resorts, etc. to spring up along the U.S.A. / Mexico border, thus aiding in helping thousands to millions gain economic security.
