Add a block that convert fe to redstone power
Put an alternator, a comparator and a few iron sheets to craft the device (ill call it the electrifier)
The electrifier looks like a comparator, have the base the height of a comparator, have two nodes, but the upper node looks like the alternator (which is also the side of the block that will gives out redstone signal)
When connect wire to the back node it will produce redstone power according to the power of the FE, the bigger the FE the more redstone power (the electrifier requires atleast 124 FE to work, can only have 3 generators connected to it)
Using the electrifier grants a new advancement called “the bigger the better”

Duplicate of #54, however this one has better ideas.
