    It's easy to sell the electricity when you have an entire train+tunnel system running 24/7/365 running on said electricity.
    And if you have signed contracts where both sides share the costs (which would be a must in this case), you can cover a lot of your costs by electricity alone.
    This IS a Russian initiative after all. With some generous help from China most probably.

    They've been planing this for a while now. (PDF link)
    Put two 10 gigawatt tidal plants to provide the power for the tunnel and the railroad up to the tunnel and connect everything over HDVC lines.

    And you don't have to worry about the economics of natural gas - Russians will make it as cheap as they need it to be for their customers to become reliant on the gas that THEY are providing.
    After all, they can afford it. And Americans love their energy cheap. Think middle-eastern oil.

    Add to that the fact that a series of service stations and storage facilities will have to be built along the railroad on both sides of the tunnel anyway.
    And while you're building warehouses for goods, why not build some tanks for the gas as well? Ship it later to your consumers at your discretion.
    Hey! It's cheaper and cleaner than getting your own.
    I'm quite sure that Russians would love to provide a line of credit to USA for that.

    As for general financing... Chinese probably really like the idea. They ARE the ones with most to gain from a quick rail line to the USA.
    And interests on the money that USA owes them alone could probably cover the costs.

    The entire plan works great if you think of the USA as the exploited side - which is the case this time.
    A trillion dollars of debt can make a "superpower" into an economic equivalent of a third-world banana republic.

    As for Russia... Selling oil is not their priority.
    They'd much rather corner the world market on natural gas.

    No big deal. The only parts that are near land are right at the very ends; the majority of the loop is 80km up in the air. How are terrorists going to get to that? ll you need is a few ground defenses with AAA at the ends, and maybe some jets around that are ready to scramble.

    LOL!

    They don't need to get to the part that's 80 km up in the air.
    Anything from crashing a plane anywhere into the structure (and this time, we're talking a Cessna not a Boeing) to causing an overload in the powerplant supplying the structure will cause it to crash.
    Only when it crashes it will be like an A-Bomb, wiping out things for miles around.

    Oh and... "ground defenses with AAA... and maybe some jets"? You remember perhaps how that plane crashed into Pentagon?
    You know... One of the biggest military installations in the world. They didn't have that kind of support.
    "Some jets" cost a LOT to fly and maintain. Bonus points for such toys being under military control AND command.
    It takes a shitload of authorizations to just take those planes up in the air, let alone to have them fire off a round.

    Near an installation particularly susceptible to gunfire, might I add.

    And should it be built so that it float in the ocean, there's a whole series of other safety issues not solvable by "some jets" - like storms and hurricanes.
    Heck... just the fact that it would be a biggest electromagnet in the world and a biggest LIGHTNING-ROD in the world would be a fun thing to observe, come first clouds.

    Also, most of the structure being "up in the air", we are not talking about protecting a ground area, but of a 3D area extending for kilometers up and out around the structure's anchor points.
    And those go along the entire length of the structure. The whole 2000 kilometers of it.

    There are not enough "some jets" in the world to guard something like that 24/7/365.

    So what? You're acting like a nuclear bomb is world-shattering or something.

    So NIMBY.
    Not in ANY yard, ANY where. Good luck building that. Particularly with THAT attitude.

    The idea of the thing, as I understand it, is that it's a giant energy-storage device.

    Try "energy sink" instead.
    It takes HUGE amounts of power to get it even operational, once you've got it built despite it being literally THE most dangerous structure in the world (imagine an atomic bomb with a pressure-switch balanced on a pedestal made out of toothpicks), and then it uses up energy continuously just to stay afloat.
    Add more if you want something launched from it.

    energy needed for each launch is very small, compared to what you'd need to launch a rocket

    Except you can STORE the energy that will be used by the rocket until you need it.
    You can't store electricity you don't plan to (or that you can't) spend at the moment. Not without significant waste.
    And significant safety issues.

    Basically, you'd have to go nuclear with that thing IF you want to absolutely, positively keep it up in the air.
    So now, when it goes boom - it is also radioactive.
    With an added bonus that you could have a meltdown first and THEN "the boom".

    80km long cables are nothing special; there's undersea cables that are much...
    The anchor cables for the launch loop probably don't need anywhere near that much strength, and can be made from conventional materials.

    Undersea cables are LAID OUT on the ocean floor.
    PLUS, they are not holding anything in place.

    These babies would have to go straight up in the air, in order to anchor the 2000 kilometer long structure to the ground.

    Difficulties of launch loops

    A running loop would have an extremely large amount of energy in the form of linear momentum. While the magnetic suspension system would be highly redundant, with failures of small sections having essentially no effect at all, if a major failure did occur the energy in the loop (1.5Ã--1015 joules or 1.5 petajoules) would be approaching the same total energy release as a nuclear bomb explosion (350 kilotons of TNT equivalent), although not emitting nuclear radiation.

    While this is a large amount of energy, it is unlikely that this would destroy very much of the structure due to its very large size, and because most of the energy would be deliberately dumped at preselected places when the failure is detected. Steps might need to be taken to lower the cable down from 80 km altitude with minimal damage, such as parachutes.

    Therefore for safety and astrodynamic reasons, launch loops are intended to be installed over an ocean near the equator, well away from habitation.

    The published design of a launch loop requires electronic control of the magnetic levitation to minimise power dissipation and to stabilise the otherwise under-damped cable.

    The two main points of instability are the turnaround sections and the cable.

    The turnaround sections are potentially unstable, since movement of the rotor away from the magnets gives reduced magnetic attraction, whereas movements closer gives increased attraction. In either case, instability occurs.[3] This problem is routinely solved with existing servo control systems that vary the strength of the magnets. Although servo reliability is a potential issue, at the high speed of the rotor, very many consecutive sections would need to fail for the rotor containment to be lost.[3]

    The cable sections also share this potential issue, although the forces are much lower.[3] However, an additional instability is present in that the cable/sheath/rotor may undergo meandering modes (similar to a Lariat chain) that grow in amplitude without limit. Lofstrom believes that this instability also can be controlled in real time by servo mechanisms, although this has never been attempted.
    [edit] Competing and similar designs

    In works by Alexander Bolonkin [7][8][9] it is suggested that Lofstrom's project has many non-solved problems and that it is very far from a current technology. For example, the Lofstrom project has expansion joints between 1.5 meter iron plates. Their speeds (under gravitation, friction) can be different and Bolonkin claims that they could wedge in the tube;[citation needed] and the force and friction in the ground 28 km diameter turnaround sections are gigantic. In 2008[10], Bolonkin proposed a simple rotated close-loop cable to launch the space apparatus in a way suitable for current technology.

    Another project, the space cable, is a smaller design by John Knapman that is intended for launch assist for conventional rockets and suborbital tourism. The space cable design uses electrodynamic levitation rather than electromagnetic levitation and discrete bolts rather than a continuous rotor, as with the launch loop architecture. John Knapman has also mathematically shown that the meander instability can be tamed.[11]

    For extra credit:

    - Come up with necessary security measures for a 2000 kilometers long and 80 kilometers high structure which doubles as a rail-gun and which acts just like an atomic bomb if something goes wrong.
    - Practice saying "But there would be no radiation even if it DID explode" in front of a mirror.
    - Come up with a reason why is it somehow NOT impossible to build 80 kilometers long anchor cables, but stacking those cables as sections of a much longer cable IS.
    - Invent a perpetual motion machine which would both power the 2000 kilometer long structure keeping it "aloft" AND provide additional energy needed to launch the payload.

    Communism has nothing to do with states - just like capitalism.
    It's just that certain states try to use it as a tool - just like capitalism.
    Neither is necessarily oppressive, but both can be used by an oppressive government.

    Problem is, there never was and there never will be a single tool that will fit (and fix) every problem or task.
    Particularly when the so called "free world" chooses allies such as Nazis and dictatorship juntas just so it could sabotage that particular tool at every step.
    Mad dictators with no understanding of the tool beyond "Got me out of the gutter and into power" don't help either.

    A family, a tribe, a small town can "run on communism" just fine. Or an entire planet.
    Anything in between has excellent chances in failing, even without outside help - because greed is a much simpler tool than empathy.
    And while seeds of both communism (empathy) and capitalism (greed) are inherent to all humans (perfectly normal human psychological concepts, beneficial in moderation, detrimental in excess), it is much simpler to get people onto capitalism than onto communism.
    "Whatever I can grab is mine and you can go fuck yourself" is a very inviting philosophy.
    Particularly for those who are already holding something in their hand.
    "Needs of the many outweigh the needs of the few" on the other hand is much harder to grasp - particularly whenever one is not among the "many".

    On the other hand, it would be simply idiotic to use capitalist approach on a human community the size of a family or a tribe.
    Town, city, state WILL "run on capitalism" though - until all capital starts to accumulate in the hands of the "few".
    Usually, that is about the time when shit starts hitting the fan.
    "Many" are then either sent to fight a war somewhere in order to get more capital into the community and possibly create an even lower class who will do all the work for (basically) nothing (thus making "many" economically obsolete), OR "many" decide that it is time for their needs to outweigh the needs of the few - and revolt.

    Due to large groups of people running at speeds of the lowest common denominator - that is rarely a good thing.
    Although, it would be a really fun thing to observe.
    Particularly if it happened in a large capitalist country, where it was programed into generations of people that socialism and communism are synonymous with satanism and cannibalism.
