Reverse Power Transformer

[DuckBoy]

Hey all, suspect other people have already discovered this one, but I made a really simple circuit that allows a low wattage circuit to feed a high wattage circuit without overloading, regardless of what's attached on either circuit.  This lets me make little gym areas away from heavy watt wires.  It also lets me drop 1K power lines down to the magma tubes to charge batteries that power more than 1K worth of spiked usage (Plastic Tubes!)  Should be reusable for all kinds of stuff. 

Design:  Source Circuit -> Battery -> Transformer -> Power Shutoff1 -> Smart Battery -> Power Shutoff2 -> Transformer -> Sink Circuit

Smart battery switches itself back and forth between circuits when it fills up to transfer power between circuits. 

Regular battery prevents dupe boredom+idling when smart battery disconnects.  Pics below will give a constant 2kW if your sink circuit can draw it. 

Note that smart battery must be surrounded with heavy wire up to both power shutoffs.

Use two smart batteries and switch between which is connected to the power generators.

You're saying 5 generators -> Smart Battery A OR B -> Transformer -> Main circuit? 

That should work just as well.  Slightly more space efficient.  If I'm right about requiring heavy wire from the smart battery to the power shutoffs, the transformer might actually be more resource efficient, at least for certain orientations due to the outlet placement on the smart batteries.  I imagine logic on toggling batteries is exactly the same as shown here, but with an additional battery attached at exactly opposite times?  If so, you could use a regular battery as the secondary, no need for the second automation input.  (Though I get that smart battery might be preferable anyway for heat purposes)

The transformer feeding the main circuit is critical to dump power out of the smaller circuit, otherwise the dupes get bored and leave instead of recharging all the batteries on the main circuit.

Just used this in a Steam Turbine build and its working great. Thanks again!

You could build two batteries. At each moment, one of them is supplying power, and another is charging.

This only works because batteries currently are not considered a consumer and won't overload circuits, correct? Seems an exploit to be able to push 20 kW on 2kW wire.

I do like the idea of having a single 2kW circuit feeding multiple 2kW circuits through automated switching. Definitely more nifty than a simple transformer.
