That is not that bad indeed, if the calculation is correct.
That still leaves the problem of the 100 km long accelerator and then you still need to breed Tritium.
The things people do for fusion...
So, a Q of ~ 4.5. After thermal conversion perhaps a net profit of 1.5 to 4 depending on the efficiency of the steam plant and if any use could be found for the waste heat.nextbigfuture wrote: .....
