Combat Dynamos vs Shiva Furnaces

Even though the Shiva Furnaces are more advanced than your standard Combat Dynamos, it's not always a good idea to replace all your dynamos with them. Shiva Furnaces and Combat Dynamos actually don't do quite the same thing.

Dynamo Units affect the delay between recharge of your energy, while Shiva Furnaces affect the amount of energy gained each recharge. The energy regeneration counter starts at 10, and every Combat Dynamo adds -2, to a minimum of 4. (so having more than 3 dynamos is never useful). This counter specifies the number of frames in between recharges that there is no energy recharge.

The energy regenerated per recharge starts off at 1, and every Shiva Furnace adds +1. There's no maximum to the number of furnaces other than the number of free slots on your ship..

Put into a formula:
energy per time unit = (#furnaces + 1) / (1 + 10 - 2 * (min(#dynamos, 3))

To get the fastest recharge rate for a given amount of RU, follow this guideline:

• If you have 2000 RU, buy 1 dynamo.
• If you have 4000-10000 RU, buy 1 furnace and 0-3 dynamos.
• If you have 12000 RU, buy 2 furnaces and 2 dynamos.
• If you have 14000+ RU, buy 3 dynamos 2-12 furnaces.

To get the fastest recharge rate for a given number of available slots, follow this guideline:

• If you have 4 or less slots available, choose all furnaces.
• If you have more than 4 slots available, choose 3 dynamos and the rest furnaces.

The table below shows the average amount of energy generated per second:
