It presents most peculiar and exacting conditions with respect to the supplying of current wllich do not render our present sources of current readily applicable. Andl it further shows the inadequacy and the limitations of our present methods of transforming energy and the possibilities which await scientific investigation, discovery and invention in unexplored fields.
