MFEs can be used for the core of generator stacks going up to eliminate current loss. HV transmitters can be used for the core of stacks going up too but there's still some loss and they require an MFE to craft. I think HV transmitters can be used on stacks that produce more than 50 EU/s though.
EDIT: Yes they can, it just requires a rather complex system of transformers to charge an MFS without wasting much current

Note that this setup still wastes half of the evergy it produces. The waste would be nearly eliminated if it produced 200 or less EU/s. I figure outside testing theories no one is going to have 20 nuclear generators operating at the same time so I declare it "good 'nuf".
EDIT 2: OK, I lied about it being "good 'nuf". I changed it to be smaller, simpler, and more efficient for moving current long distances. The splits being hooked straight to the generator stack made each split lose current per wire so I put another HV transmitter right before them to make the transformer system itself lossless even if the wires leading to it aren't. It still maxes out at 200 current though.
