Is that really true?
2808 bunches * 1.15 * 1011 protons in each bunch * 7 TeV = 362 MJ as the total kinetic energy carried in the circulating p beam.
A Nimitz class carrier has a displacement of close to 100,000 tons, therefore having a kinetic energy of 10.8 gigajoules at 30 knots. For a ship travelling at 30 knots to have the same kinetic energy as that beam, it would need to have a mass of 3352 tons, which is a far, far smaller ship.
Or, have I done something stupid? Corrections, of course, are welcome.
The French aircraft carrier Charles de Gaulle has a light displacement of 38,000 tons.
Using google calculator (double checking is good, right?):
(38 000 short tons * ((30 knots)^2)) / 2 = 4.10552603 × 10^9 joules
2808 * 1.15 * (10^11) * (7 TeV) = 362 162 376 joules
Still off by a factor of 10.
