RE:RE:RE:RE:RE:RE:RE:RE:DoingIf RSX is not faster than SX, I doubt CapEx will be lower. At smal plant size, there are diseconomies of scale, so (small) RSX (plant) needs cost advantage just to be sane cost as larger SX plant (MP).
If an RSX plant is built, but never prodices (as with Molycor's plant a decade ago), its CapEX per tpa is infinity times more expensive than an SX plant which actually produces. Could that happen? I don't know, but with the illustrious management running Ucore, who knows.
