    It's worse still. At $50/ticket you need 274k daily riders.

    $50? No way. That is 12c per mile. No other high-speed train in the world has ticket prices anywhere near that cheap. In France, the cost is 50c per mile. In Germany it is 40c per mile. Even in China, where costs are way lower, and rail is heavily subsidized, the cost to the consumer for high speed rail between the big cities is 22c per mile.

    The tickets for LA->SF are going to be over $100, and likely closer to $200. So it will be both slower and more expensive than flying. It will be also be way more expensive than driving, or taking a bus.

    It's quite relevant because it is an indication of whether the high-speed rail is economically viable.

    No it isn't. All the people taking planes are not going to switch to the train. The planes will still be available, and will still be faster. And there will be other options 20-30 years from now, when this train is finally ready, ... like high-speed self driving vans/buses, and slow self-driving "sleeper vans" that pick you up at 11pm from your home, and deliver you, fully rested, to the front door of your destination at 8am the next morning. They will be electric (no CO2) and since they drive slowly and can convoy in platoons, they will be very economical. If they cost $50k each, then 10 of them will cost less than the capital cost of a single seat on the train.

    The "cost per seat" of the train is only meaningful if you know you can fill it. If you look at the projected ticket prices, and the other options that will be available, that is very unlikely.

    If you divide the likely cost of this train by the number of seats, it will cost about $500,000 PER SEAT.

    Just how much is the capital cost per seat of the planes that are the real competition for this train?

    Irrelevant. Those are either sunk costs (airports) or paid for by the private sector (planes). If it isn't going to be paid for with my future taxes, I don't care what it costs.

    In Japan the rail company builds large shopping centres around each station. The rent it gets subsidises the fares.

    In America, we build huge parking lots around the train stations. The assumption is that everyone will drive to and from the train station at each end of their journey.

    By the sound of it It's going to be so expensive that if I could afford to take it I'd just take a plane instead.

    This project will take decades to complete. By then there will be self-driving battery powered buses on I-5, for 1/3 the price of a ticket on this train. If you divide the likely cost of this train by the number of seats, it will cost about $500,000 PER SEAT. That is just the construction and capital cost. The operating cost will add even more. Nobody will be able to afford it without big on-going subsidies. Meanwhile, for the cost of a single train seat, you could buy several buses with over a hundred seats in total.

    The solution is obvious: We need to ban the buses.

  8. Re:Ridiculous claim in summary on California's $68 Billion Bullet Train Project Faces Major Hurdles (latimes.com) · · Score: 1

    This is absurd

    Nope. Three times over budget is typical for public works projects. It is how the game is played. The numbers are intentionally lowballed to get the project approved. The politicians play along because these boondoggles are always popular in the beginning. Once the schedules start to slip, costs start to mount, and public opinion starts to sour, it is too late. There is too much sunk cost to abandon the project, and the politicians that approved it are either no longer in office, or nobody remembers who voted for what anyway. The contractors win, the politicians win, and the taxpayers are left paying the price. Meanwhile everyone thinks the next big project will be different.

    A solution for this is to fund these big projects with private investments. Then the government will buy the services that they provide, such as, say, a guaranteed $100 subsidy for each passenger that takes the train from downtown SF to downtown LA. Since this train is projected to cost $500,000 PER SEAT, that would mean a payback after 5000 trips. If no private investors can be found, that should be an obvious indicator that the project cannot be built at the projected cost.

    Intelligence is the ability to formulate an effective initial response to a novel situation.

    It's still kind of looking if you arrange for it to do something that you can look at later to indirectly observe what went on when you weren't looking.

    But if the behavior is different if you watch continuously vs. looking away and then looking back, then how does the universe "know" that it is being observed? The obvious answer is that the universe isn't real. It is a simulation run for our benefit, so it only continuously generates what we can see. If we look away, the simulation is paused, and then when we look back it is quickly updated in batch mode.

    This is just like rotating a multi-faceted polyhedron in OpenGL. The shaders skip the hidden polygons, and then quickly update them as they rotate into view.

    All those people and only one phone? Why not both.

    Because that will sow confusion, and likely cause delays. Security will call 911 within a few seconds anyway. So now 911 is getting two calls, tying up two operators, who have no way to know that they are the same incident. So two emergency response teams will be dispatched. One will be directed, by security, to the patient. The other will be looking around, trying to figure out where the patient is, and which door they should go in. When they see the patient being treated by the other team, they will assume they are there for someone else. So they will wander around some more, trying to figure out what the hell is going on. Meanwhile, somewhere else in the city, someone is dying because an EMT is not available.

    How would they know what the atoms do without observing them?

    Check back later, and see how many tunneled while they weren't looking. If they tunneled, they will be in a different location.

    If they find there was tunneling while they weren't looking, that is pretty strong evidence that we are living inside a simulation. The universe behaves differently if we are not looking, so that God can save computing resources. There is no point in calculating details that no one will see. Just like the way OpenGL can skip the shading of hidden polygons.

    Solar thermal is a solution to the wrong problem. Electricity demand, and thus prices, are highest in the daytime, and lowest late at night. So by shifting production from day to night, they are turning gold into lead.

    There may be a time, decades hence, when solar makes up a big enough slice of electricity supply, that it needs to provide base load power. But that time is not now.
