This thread is for designs using a Shard of Emerald from the week 18 mission.
The shard is not the stone known as Emerald, but a piece of the Being known as Emerald. (Emerald is NOT a K’ias, but may be a relative of Melvin for those in the know)
It gives off enough ambient energy to power a wide array of devices and functions in the same way as a Sylvan power converter.
