Filament Factory

* Old World

**Filament Factory** is a Production Building which turns  Coal into  Filaments. It can be built only in the Old World (and Cape Trelawney).

## Productivity

It takes 60 seconds to produce 1 ton of filaments from 1 ton of coal so the production rate is 1 ton of filaments per minute. Productivity can be changed by adjusting working conditions, using items and electricity.
