I understand that it is not effective. I am interested in another aspect of the issue. Why they do not work on the 3 generators. The fact that the loss is all I care. Generators operate continuously without delay.
Each generator emits a 10 EU-packet per tick. So 3 generators producs three 10 EU-packet per tick.
Each copper cable causes it to lose 0.2 EU per block.
40 blocks causes it to lose 8 EU per packet.
At the end there are three 2 EU-packet per tick.
So 6 EU/t total to all the Luminators. (I think the cable loss applies to all the consumers, never knew, always used Glass Fibre or Superconductor from GT)
6 EU/t total should not be sufficient.
If you have a BatBox as a buffer within 4 blocks of any generator, the BatBox should emit a 32 EU-packet per 1.067 ticks.
40 blocks causes it to lose 8 EU per packet.
At the end there is a 24 EU-packet per 1.067 ticks, or 22.5 EU/t on average.
22.5 EU/t total should be sufficient.
If you want a less complicated power system, try Michael Jacksons Minecraft Joules. Its mechanics are rather bizarre also though. However if you still insist on using EU then just spam Glass Fibre Cable. Rather cheap, a diamond, gold ingot and silver ingot for 8 pieces with GregTech. With or without, 2 silver ingots and a diamond for 6 pieces, or 2 redstone and a diamond for 4 pieces.
I remember back in Beta 1.8 when they had twice their power loss and produced 12 pieces instead.
