Passive Generator

A slow, hands-off trickle of energy from a nerosium core.

Obtaining

Craft (shaped): a nerosteel frame around a Block of Nerosium, wired with Redstone —

N N N
N B N
N R N

N = Nerosteel Ingot · B = Block of Nerosium · R = Redstone

Core slot (GUI, hand or hopper/pipe fed): raw nerosium, a nerosium ingot, or nerosium dust.
One Raw Nerosium, Nerosium Ingot or Nerosium Dust runs for 24,000 ticks (20 minutes), making 8 FE/t into a 100,000 FE buffer.
Auto-push: it pushes power into any machine or Battery that touches it. A pipe can also pull it out.
Weaker than the Combustion Generator but ideal as set-and-forget base power.
A Nerosium Grinder uses 20 FE/t, so one Passive Generator runs a grinder at about 40% speed. That is fine for a start.
