The small nuclear battery which energized the moisture-reclaimer, the heating units, and especially the air-restorer-not only for turning its pumps but for providing the intense internal illumination necessary to promote the release of oxygen in the photosynthetic process of the chlorophane when there was no sun-had been replaced by a chemical battery of a far smaller active life-span!

The internal lights of their air-restorers could be used again, augmenting the action of the pale sunshine on the photosynthetic processes of the chlorophane.
