Sources

This building becomes available after the Metallurgy 2 technology is learned at a University of Harmony.

Compare all Furnaces.

Cost

Built in a Medium Construction Site.

Use

Smelt all known ores.
Uses Petroleum for fuel.

Construction

To construct, place a Medium Construction Site at the desired location, then select Projects > Furnaces > Persephone Furnace.

It must be built 65 or more coordinates away from any other Persephone Furnace or Hades Furnace.

If there is a Persephone Furnace or Hades Furnace up to 64 coordinates away, you will get a dialog box, "You must locate any water cooled furnace at least 64 coordinates from any other".
Has to be 65 or more coords away in both north-south coordinate AND east-west coordinate

It must be built near a water source and away from a road

If there is no water nearby, or if you construct too close to a road, you will get a dialog box, "Persephone Furnaces are cooled with water, and must be built near a natural source, and away from paths."
A Water icon does not necessarily meet the requirements, and equally you can build where you don't get a water icon.

Note: Due to a bug in the code, until 23-AUG-2017 the dialog box was not working correctly, this has now been fixed. Silden 14:55, 23 August 2017 (EST)

To prevent attempting to circumvent the distance restriction by constructing two furnaces at the same time or by repositioning it after construction, every time you fire a Persephone Furnace or Hades Furnace a check is made for any furnaces nearby. If there is another furnace 64 coords or less away, ALL affected furnaces will display in the main channel Operating a water cooled furnace too close to another causes it to become unstable. It will not operate when attempting to fire it.

Yield

Burns 28 petrol per day (28 ticks per day)

Ore Used	Petrol Used	Metal Yield	Time opened	Ore Cost/Metal	Metal per Fuel
20,000	9	580	8 hours
20000	28	1340	24 hours (1 day )	14.93	47.85
20000	56	2000	48 hours (2 days)	10.00	35.71
20000	84	2400	72 hours (3 days)	8.33	28.57
20000	140	2860	120 hours (5 days)	6.99	20.42
20000	224	3200	192 hours (8 days)	6.25	14.28
20000	450	3560	385 hours(16 days and 1 hour)	~5.618	7.9
20,000	1,000	3,780	35 days, 17 hours, 8 minutes, 35 seconds

Lower Ore gives a proportional reduction in metal, but take the same amount of time. 2,000 ore using 28 petroleum yields 134 metal after 1 day.

20,000 Ore will increase metal in steps of 20.
