It turns the moon into Energus station. Over time, its huge antennas focus more precisely, increasing the energy production at any object in the center of the current local coordinates by the formula
2 * level *( -1 / (0.1 * [time of standing on current coordinates] + 1) + 1)

If there are several energuses in orbit, a senior level station is in operation. The bonus value is updated at least once a day. It is impossible to build it together with other moon-forming structures. The first level cannot be destroyed or eaten by Lexx.
