No, that's not what he's talking about. This is completely possible and when you look at how hit-or-miss things are, such as block placement, I assume that this is a balance issue or a bug. You use some regular EU to extract FE from forcicium in the extractor. You then take that FE and output it through the FE -> EU Converter. Then you take the EU it has just made and power the extractor. Let this run for a little while until the capacitor has built up some energy, then turn off the FE -> EU Converter and change the power output to maximum (2048 EU/t). Turn it back on, and the EU-FE-EU cycle will be operating at 2048 eu/t minus the cost of running the extractor, which is dependent on your upgrades. You can then wire the EU converter up to other things, and you are essentially just burning forcicium to create EU at upwards of 1000 EU/t. However, if you put too much drain on the energy loop, the overall energy will drop. Having just the right amount of upgrades, the right block placement, the right wiring (4x HV is required for the power loop, and anything you attach to it will explode), it is all very tricky and requires some fiddling, but I figured it out in an hour or so. You can do it!
