comment Why is 7 TeV considered as a big amount of energy?
I'll try to answer that with two assumptions: the 'average' collision rate is held constant for the entire season of "600 million collisions per second" (Source), and the energy released in every collision is ONLY the kinetic energy of stopping the particles. Thus, $600,000,000\ per\ second * 7\ TeV * 2 = 1345.83\ Joules\ per\ second = 1.35\ kW$, or $0.001\%$. This is, of course, absurd, as the 'purpose' of the LHC is more than just 'producing collisions', and the 120MW includes additional processing, cooling, etc.

comment Is there any disadvantage to sending rockets straight up?
Right, but crossing into the Moon's SOI is roughly equivalent to what I meant by crossing the Earth - Moon L1.

comment Is there any disadvantage to sending rockets straight up?
Launch Site latitude is dependent on the orbit desired and chosen to minimize fuel. For a Polar orbit, the equator is the worst place to launch as you'll have to spend $500 m/s \Delta v$ extra fuel to cancel this effect, and the north or south poles would be ideal. For equatorial orbits the direction of Earth's rotation (including geostationary), indeed the equator is the ideal place to launch and has the minimum fuel requirements, but these 'ideal' locations have to be tempered against the practicality of getting a rocket and launch facility there.

Picture posted showing the trajectory for a 'straight up' burn. I might try this in KSP later and post the video.
