After some quick and sloppy testing, a few quick facts for those who haven't done their own:
(1) The new power blocks stack bonuses the same as capacitors, not reactors, so group them all together up to the soft cap, not in line patterns.
(2) There is a soft cap, it seems to be 289 power per block, and it is achieved somewhere in the range of 7200 blocks in a single group. The power will still increase from here, but the power per block ratio will slowly decline as their numbers increase. This cap is per group, so multiple groups will work fine and surpass the soft cap.
(3) The new power blocks add a button to your hotbar that you can activate/deactivate
(4) The new power blocks do not seem to work with logic, but I only tested it with an activator block so far. Sigh.
(5) The new power blocks act as a capacitor which slowly charges when off or quickly charges when turned on and will discharge its full load into your system in about 8 seconds. If the amount being transferred is larger than the amount the ship needs or has capacity for, you lose the excess.
(6) After transferring its full load to the ship, the new power blocks will continue to provide power regeneration as long as they're kept active.
(7) 7200 power blocks will provide about 1.25m per sec and an initial dump of around 8.8 million. Not exactly the model of power generating efficiency.
(8) The new power blocks do not remember their last state, so if you leave them on when you log off, they will be off when you log back in.
There is some poor labeling or explanation as to what the actual values mean.
The off rate is the actual power produced continuously. Yes, it will produce that much power even in the on state.
The on power isn't how much power is produced at all it would be better labeled as discharge rate. The rate at which it will discharge the capacitance.
I don't consider these even a near reasonable replacement for docked power.
Docked power is all about gaining continuous power not intermittent power. It is about having a constantly large power system.
There is also another misconception. Docked power does not always require a beam to transfer power. Docked power can transfer power up stream with no beam at all.
Build a primary ship with its own power system. Then dock a power supply to that frame. Then connect whatever you want to supply power to to the docked power system.
While docked power systems are target-able they are also capable of producing massively larger amounts of power. Which means they can provide greater shielding power, carry more armor. You can also provide greater protection to the docked area.
Aux Power systems do no produce enough power to adequately shield and protect themselves let alone provide thrust for their added mass.
Not just that they create an added risk and are harder to protect.
To get the max efficiency out of them you have to create a massive target. The larger the groups the larger the explosions and ship structure damage can be. The larger the groups the larger the space and armor needed to prevent explosion cutting to other areas. I know that because I built compartmentalized groups and tested it and watched the explosion blow through from group to group with various armor and sized groups and so on.
It isn't like you can use their power to boost the shields or anything. Any power not used when it is discharging or captured is simply lost.
So to effectively use an aux system you have to have enough normal caps to catch that power.
With 7200 blocks of the aux you can get around 245,000 continual power generation. You will have to leave it in the on state to make use of it all the time. In the off state it does not reach the external systems. You can however charge the capacitance of the aux in the off state then dump that back into the primary system.
Docked power system. Upstream use.
899 reactors 999 caps 1 core 1 dock 1 rail. produces 1,494,000 e/sec. that is 785 per block continuous power.
Docked power system
pros:
Can be chained, can provide continuous power unlimited
Can provide enough power to shield and protect itself
Is considered a separate entity from primary ship
Easy to replace
negs:
Can come undocked while in combat
Aux power system
Pros:
Provides some aux power greater intermittent and much smaller continuous
Negs:
Must be large group size to make use of producing large target area.
Volatile explosively destructive, must be isolated from not only itself but other parts of ship. A rather small amount of damage can result in massive damage to ship structure causing loss of ship.
Does not produce enough power to provide shielding / protection for itself with thrust. (In other words it can provide an adequate amount of power to protect-self and whatever protection is used to protect it provide power to move that protection.)
It also isn't good as a power boost to use weapons because it requires manual turning on and off. maybe if multiple weapons could be linked to it for added power that would help.
It will never be useful for continued weapons fire.
Even as an auxiliary system the charge rate is far to slow.
(Personal opinion because of the volatile nature of these I couldn't justify putting it in a ship if that charge rate was raised to 2000 per block.
Maybe, if the combat shield recharge rate was raised to 100% and the primary charge rate of shielding was doubled to provide adequate protection.) Right now the auxiliary power system reminds me of ammo storage or boiler systems that could destroy their own ship.
Simple conclusion at the end of testing. I can find no valid reason to ever use the auxiliary power system on a ship having weighed the pros and cons under the current values being used.
An auxiliary power system of this nature is not a continuous power system thus should never even have been considered for replacing the docked power system which are entirely about continuous power. It has never been an issue of wanting a short term boost in power.
[doublepost=1474039962,1474039103][/doublepost]Can you imagine what it would take with the aux system to replace the following docked power supply. Remember these produce continuous power. I have a ship I am building with 5 of these in it. Plus the primary hull has its own power system.
In truth I could dock the 5 together and come off the last one and get a combined amount of power. There are no beams used in this power transfer system at all.
