A proposal for iridium wire:
Through the use of quantum entanglement, iridium particles can be linked with each other through time and space, allowing energy to transfer from one point to another instantly!
Where D = diamond and I = iridium.
This makes but a single iridium cable. (Making two was considered OP.)
Now, place one iridium cable at a power source, and another iridium cable no more than 100 blocks away, and you get lossless teleporation of up to 512 EU/t between the two!
How does a cable know which cable it's linked with? Why, use a FreqTrans to link them together, much like a teleporter!
