The near side of the moon, from where energy would be beamed to Earth, according to the Luna Ring project. Luna Ring is a speculative engineering project which consists of a series of solar generators, disposed around the equator of the Moon, that could send the generated electric energy back to the Earth via microwaves from the near side of the Moon.

Physically, a Token Ring network is wired as a star, with 'MAUs' in the center, 'arms' out to each station, and the loop going out-and-back through each. [20] A MAU could present in the form of a hub or a switch; since Token Ring had no collisions many MAUs were manufactured as hubs.
The ring starts at the consumer unit (also known as fuse box, distribution board, or breaker box), visits each socket in turn, and then returns to the consumer unit. The ring is fed from a fuse or circuit breaker in the consumer unit. Ring circuits are commonly used in British wiring with socket-outlets taking fused plugs to BS 1363. Because ...
An Einstein Ring is a special case of gravitational lensing, caused by the exact alignment of the source, lens, and observer. This results in symmetry around the lens, causing a ring-like structure. [2] The geometry of a complete Einstein ring, as caused by a gravitational lens. The size of an Einstein ring is given by the Einstein radius.
Teela had restored starship engines to their original purpose as attitude jets, but only had enough for 5% of the ring. Louis explains that the meteor defense system can generate a massive stellar flare (normally used to power the laser weapon) to provide twenty times more fuel to the attitude jets to move the Ringworld back into position.
