This document presents a general analysis of charge-discharge during pile operation. It is not a detailed technical, operational, economic, or political analysis but, rather an attempt to cover the subject with a broader viewpoint than is usually prsented in the many detailed reports which have been written in the past five years. This letter is occasioned at this time because efforts are in progress to implement plans for proceeding with the expenditure of substantial amounts of money in order to demonstrate that the system, as developed, will allow the attainment of certain desirable objectives.
