Talk:Coal Bin/@comment-1838919-20140913043007

This is quite useful. Coal is the weakest output as you can only build 2 coal mines right now. Hopefully In the future Z2 will add at least 1 more coal deposit to mine.

This "decoration" is important because 4 of them can boost your Coal income by 24%. The penalty to House-gold-income is minor. The greater problem is that 4 of them cost 96nanopods. Nanopods can be gained from using Tapjoy on Android, but on PC Tapjoy isnt usable.

Summary, really good but unusable if youre on the PC.

Its mainly a decision of whether to make the Coal Mines Premium or not. One advanced coal mine costs 160nanpods would up to 100extra coal per hour. a single advanced coal mine is better than all 4 coal mines, but if you combine 2 advance coal mines, with 4 coal bins you can have nearly 500coal per hour. I dont know why you would need that much though.
