## 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 by 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 that is waited between two recharges.

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) / (10 - 2 * (min(#dynamos, 3))`

To get the fastest recharge rate, 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:
