Alien Metal

白炽灯，由电流通过涂有透明绝缘漆的电阻电缆产生。

An incandescent light, created by electricity running through a resistant cable coated in a transparent insulating varnish.

The depth of sediment coating suggests recent construction, within the past ten years. The pillar that mounts the light is much older, on the scale of centuries.

This lightning technology is characteristic of the early Electronic Age, commensurate with Earth's 20th or 21st century.
