Yeah that's a crazy setup, though I dunno what kind of power it actually sustains over a long period (since its bouncing around in heat output)Did you see tomcats reactors at the end of the thread? - points for insane complexity.
Theres also a decent enough design @ 600eu/t on page 4 (assuming it will still work)
At the end of the day, you can still easily just create a boring old (non-cooled) MOX reactor that outputs 800-1000 eu/t with far, far less complexity. There's no incentive to play with the new reactor mechanics other than that they're "interesting."
