| -4- Contd. will depend, amongst other things, on the internal resistance of the battery and on the first group of connecting wires mentioned. The above are merely given as examples. The intention at the moment is not to treat the matter exhaustively but generally. It may, in spite of the great practical use of systems which suffer from these defects (they are defects in this sense - that though they may not be defects when everything, particularly battery and connections, is looked after correctly and kept in proper order, nevertheless they may be considered as defects in that they do provide loopholes for failures of and damage to units of the system when supervision is not up to scratch, e.g. burnt out armatures, fuses blowing, life of battery reduced or battery electrolyte being evaporated away, etc. etc) be argued that such dynamo-battery systems are fundamentally wrong in principle, and this is the case to a large extent even when everything is in perfect order, because they do not, unaided by some additional controller, human or automatic, supply the right allocation of battery charge from time to time. They provide no control whatever in the absence of the battery, rendering it quite impossible in those circumstances satisfactorily to utilise the remainder of the system or any portion thereof, at all.
