Switzerland's Mega Tunnel Sets Record

Anonymous Dupaeur writes "Switzerland, co-home of CERN and numerous other world organizations, has come closer to the completion of their recent megaproject: the Gotthard Base Tunnel, which will be the largest railway tunnel made by man. The project is due to be completed in 2017, and will host 200 to 250 trains a day with a significantly larger kinetic energy than the LHC's beams." After the completion of today's work, the tunnel is now 57 kilometers long, surpassing Japan's 53.9-kilometer Seikan Tunnel. There are a few longer tunnels in existence, such as the 137-kilometer Delaware Aqueduct, but they all move water rather than people.

    Is there a larger, naturally occurring train tunnel somewhere?

    Mentioning CERN because it's hosted in the same country as the tunnel? Comparing an entire train's kinetic energy to that of a fundmantal particle's kinetic energy? WTF?

    Why don't they compare the number of trains going through it per day to the number of possible subatomic particles while they're at it?

      What needs to happen is someone in Washington needs to grow a spine and raise taxes to pay for what we need to pay for, and start trimming the fat going forward. The military is a great place to start

      Good luck with that. The military-industrial complex Eisenhower warned about is far bigger and more powerful than even he could have predicted, and it's basically unstoppable at this point. Defense contractors lobby Congress to fund giant defense projects of questionable value, Congress people get those giant defense projects built in their districts, and the jobs that get created turn into votes to get them re-elected and more money for the contractors to expand their lobbying efforts. It's a cycle that's good for everyone involved except the taxpayer (other than the ones in the Congress person's district, of course).

      Hell, the Secretary of Defense himself got raked over the coals for even daring to suggest the military didn't actually need all of the money they get every year, and wouldn't it be great if they could stop buying all this crap they have no use for. If the guy in charge of the military can't cut the military budget, then who the hell can? Congress sure isn't going to do it, nobody ever gets elected by being "soft on defense", especially in our post-9/11 fear-based system.

More than 6,000 of our nation's 115,000 bridges that are part of the national highway system are structurally deficient, and we can't even get a new tunnel built to link traffic from New York and New Jersey to Manhattan.

    115000000000*2808 = 322920000000000 * 1/1000000 J = 322920000 Joules = 322 Megajoules, and 1 Megajoule is approximately the kinetic energy of a one-ton vehicle moving at 160 km/h. So it just takes 200 cars on highway to achieve kinetic energy of LHC

    Each particle has 5 TeV of kinetic energy.
    There will be (roughly) 1e12 particles per bunch, and (roughly) 1e3 bunches per pulse.

    This works out as ~800 MJ per pulse.

    That is the same energy as a 1e6 kg train moving at ~80 mph, so the comparison is not as daft as it would seem.

    (Note: Those numbers are all pretty rough, and I'm sure someone will be along soon to correct me soon, but the point is that the LHC beams store waaay more KE than you would imagine.)

    It's 40 minutes for 200 trains per day with 400-1000 passengers each. So it's at least 80,000 times 40 minutes per day saved, and if the tunnel gets used for 50 years, it saves 57.600.000.000 minutes or about 1 billion hours. Makes $10 per hour saved. Sounds sensible to me.
