The space within the no-room is, therefore, effectively invisible sauce light, for example, is stopped before it enters the no-room aad is recreated on its other side. The no-room is similarly "not there" for radio waves, gamma waves, X rays, and the like. Note that the generators of the Holtzman Effect fields, GA, Oa, Gb, and GB, lie within the no-room and are themselves concealed. For the sake of simplicity in exposition, only two overlapping spheres are shown in the diagram. Such an arrangement would provide invisibility to an observer standing within the open end of a cone, with the point of the cone lying at the center of the no-room, and the axis of the cone lying on an imaginary line drawn through the generators, opening to an extent of about 120. Existing no-rooms utilize three sets of paired spheres and twelve generators for invisibility in all three dimenbionb, LHTO'S NO-ROOM. The no-room that sheltered the Rakis Finds is perhaps the earliest example of the effect known, and although similar in effects achieved, is considerably The outer line represents the Holtzman Effect surface; the inner line the glowplant layer. The diagram is only schematic, since the separation between the two layers averaged 1 micron. 1XIAN NO-ROOMS 353 different in its mechanism. The technology that enables the generation of harmonic, self-triggering Holtzman Effect fields was not available when Leto made, or caused to be made, his no-room. Yet the technology he had was used to surprisingly good advantage, considering its rudimentary and truly primitive nature. Leto's no-room was composed of a partially collapsed Holtzman Effect sphere (see Diagram 2). Inside the surface of the field and parasitic on its energy leakage was a network of genetically modified glowplants from the planet Niflheim. These plants, long misclassified as crystals, formed an almost solid intertwined layer of monofilament strands no more substantial than a cobweb. They functioned similarly to fiber optics, except that they transmitted not just light but any received radiation. Such plants absorb radiant energy at their positive end, step it down by one chronon (an amount too negligible to be detected), and emit the radiation at their negative ends as waste. Rather than absorbing and recreating radiation as the modern no-room does, they channeled radiation around the no-room. When implements at the construction site above the perimeter of the no-room fell through the weakened ceiling, the relatively enormous amount of solar energy falling on the plants stimulated growth to close the gap at a rate too fast to be seen through the obscuring dust. What workers at the site took for the excavation floor was, in fact, Light reflected from the floor of the chamber, channeled around the contents of the chamber, and emitted from the now-exposed glowplant layer.
