I agree it was overestimated, note to self: always redo ppl's maths.

1) number of barrels of jet fuel per day in switzerland:

34000 barrel / day = 0.39 barrel / s

2) energy in a barrel of jet fuel:

1700 kWh / barrel = 6120000000 J / barrel

3) total power for switzerland:

2.4 GW

so more like 2-4 reactors for all switzerland.
