k, so basic setup is as follows:
1. Hook up generator of your choice to MFE.
2. Run MFE output through LV transformer
3. Run LV transformer output through a series of batboxes
4. Input to MFE again from a different face than the generator input.
You now have an MFE which continuously circulates EU (unless you put a lever on one of the batboxes or MFE itself)
Reason for doing this:
Prevents build up of EU at the end of a supply chain, or having to stick a mass fabricator next to an offline MFSU to soak up wasted energy.
...is this a bad thing to do in SMP servers?
