Echelon mirror

An Echelon Mirror increases the solar energy collected by solar collectors in ALL SURROUNDING SQUARES by +1. It also counts as a solar collector for the purposes of collecting in its own square, though it does not receive any additional bonus from other Echelon Mirrors.

Echelon Mirrors have a significant negative ecological impact.

Background
With experience and improving technology, the colonists developed methods for improving the efficiency of solar-power farms. An echelon mirror system used a complex arrangement of lenses and mirrors to focus solar energy more intensely on high-efficiency solar cells. The result was a significant increase in solar-cell output over a wide region.
