But applying a redstone signal will invert the transformer, turning the HV back into EV. My thought was that once you put HV into an MFSU it only kicks out 1x512EU/t, rather than the 4x512EU/t that goes in to it, so you can't reset the cable loss with an MFSU whilst keeping the EV. However, if you used a couple of transformers to convert it to EV and back every 30 blocks or so, you could run it indefinitely, and you would still be getting 4x512EU/t when it reached the end of the run.
