Sci-Fi Tech We Could Have Right Now (For a Price) 526

PlainBlack writes "Possibility isn't limited by technology. And it's certainly not limited by human imagination. What makes something impossible is the lack of cold, hard, cash. Wired blog takes a look at 10 science fiction technologies we could build, if they weren't so expensive. 'New York-L.A. Maglev Express - Cost: $70bn (Based on established construction costs). At $70bn, it's tantalizingly affordable by the standards of this roundup: a train that could beat airliners from one side of the country to the other. Many agree that Maglev has enormous potential. Bite-sized examples are in operation all over the world. Birmingham, England, had the first in the 1980s, though the promise of airliner-like speeds on land is still unrealized. The British system sped along at a pathetic 26MPH and was designed to get air travelers to the planes, not to outrun them.'"

          Still less likely - You know EXACTLY which route it's going to take, and can build in controls to your "Command Center." A plane in the air is all on its own while a train is bound by a number of things, least of all tracks. At the very least you could intercept it with another large object, not to mention any other mechanism built into the train/track for such an event.

          It's not perfect, nor fool-proof, but it's far safer. At least you can't fall 30,000 feet.

            Most high-speed trains are electric.. All you have to do is cut power to the line and have an automatic "power gone for too long? apply brakes" control into the train's automation. (yes, there is a bit of backup power on the train)

              Actually - they are usually failsafe. You don't need residual power.

              Think about what that means - their failure mode is safe. It is a well established design and engineering principle.

              For example, the brakes are held open by compressed air. If something goes wrong the compressed air supply shuts off and the brakes stop the train.

          Most regular run-of-the-mill a-dime-a-dozen subway trains have systems in place so that if the driver metaphorically "puts his foot down" ignoring the signals, the train will stop anyway, with no way the driver could over-ride them.

          Smoke and mirrors. Sure they could. But if you block that route with heightened security measures then they can just take out a major road intersection or bridge, or many other possibilities -- essentially anywhere people gather is a security risk.

          If you believe that to be true, then the terrorists have won. Air travel is already a complete nightmare. After 6+ years of security threats you'd think that they would be able to come up with better ways of moving people through controlled spaces like airports, but no... they haven't. Lame really.

        That's easy. You still live. Now if someone made a copy of you and then you died, then the question becomes murky.

If you get amnesia and have to relearn your former life through the testimony of those who knew you and your personal writings, are you still you?

        Can anyone else be you? Is a copy you? Are you still you if you're the copy? Are you the person you were copied from? Are you really the same person as the child you were many years ago?

      Flying Car - you don't actually want this, you want quick easy transportation.

      Cheap Nuclear power - Well, if someone finds a scalable way to retrieve uranium from sea water or harvest He-3 from the moon (and a way to use it) we're good.

      Video chat - it's already cheap. Buy a webcam, find someone else with one, and pay your internet bills. What you want is for more people to buy webcams. And for your phone to be connected to your computer.

      Space travel for the masses - first you need a space destination for the masses. If you build it, they will come. But not for a while, and not until you have a destination. 20-50 years if people want it.

      Cure for cancer - see cure for common cold.

      Cure for common cold - Why bother with *just* the cold? Why not think big - mechanical immune replacement. Just build a tiny robot with a white list of what not to kill. Shape it like some really successful predator that's been around for a hundred million years. Strap a lazer to it. Then socialize medicine, because there's no money in a magical cure-all.

      Strong AI - Ten years. Well, not really. But something that passes a turning test, even if it's just simulating intelligence. Give it a few hundred terabytes or so of choices and pattern matching combined with AI a bit better then what we have now.

      Voice commanded appliances - Well, it might give you something not entirely unlike tea every time... but just connect all electronics in your house to your computer. Set it up like a mainframe and clients. Does your video-chat thing too.

      No more oil - see nuclear power.

      3D UI - not helpful. You get full voice input and some AI to make things easier by guessing what you're doing unless you ask for a command line... but 3D UI really doesn't help. Do you need to square your desktop? Does a browser with depth help? Are you going to wear polarized glasses so a screen can *be* 3D?

      Cybernetic Implants - Yea, sure. But not soon. You don't get to see one, unless they fix that death thing before... well before you die.

      Energy-beam weapons - NO. Seriously, not helpful. Kinetic energy is really more useful... I don't see any advantage to lazers and the like over just pushing things really fast.... lazers are faster but you can course adjust real "objects." And pack them with explosives.

      Easy-to-maintain PC's - Define "maintain." Ah fine, why not. Get redundant hard drives and processors, make full RAM+ROM backups and get a *serious* "undo" button. Shouldn't be that hard. Then rewrite your OS from the ground up so you can't screw it up. I'm talking make it so that you could click a button to fix anything wrong, because there's a list of every option and what value it has. Verify all relevant options are correct, and then fix anything that differs from the "standard" install.

      Keyless cars - Already have them. Fingerprint and so on.

      Non-lethal weapons for cops - they have those. They don't really help. What you need is more training and accountability.

      Tires that don't blow out or go flat overnight - Full rubber tires or auto-resealing tires. You can already get the kind that you can drive to a mechanic after what would have been a blowout... they have some kind of goo that driving fast plasters to the walls and is thick enough that it keeps air in but thin enough that it closes over holes. Solid rubber tires also exist for government officials... don't know if they're street legal, though.

      Reliable Car Batteries - you follow recommendations on lifetime and get a car that turns the lights off 10 minutes after you take the keys out and modern batteries are as reliable as they get. Unless you get solar panels to charge them or something, but honestly if a battery goes dead these days it's probably your fault... and it's getting harder to make such mistake

    Also why a maglev from ny to LA? There are supertrains that haul ass pretty damn good. 24-36 hours from NY to LA is something that people would certianly pay for, and that's only a average of 90mph.

      From Wiki: since the opening of the LGV Est [a new rail link in France], a TGV covers the 104¾ miles (167.6 km) from Lorraine TGV station to Champagne-Ardenne TGV station in 36 minutes, at an average speed of 174.5 mph (279.3 km/h)[4]. This service calls at both stations and so is representative of a high-speed service with 100 mile stopping frequency. Moreover, the TGV that achieves these timings is only capable of 198 mph (320 km/h) ("only" because Spain just opened a line using trains capable of 350km/h).

      NY to LA is about 4000km, an average speed of 280km/h gives 14 hours if you stop every 100 miles (25 stops -- are there 25 places important enough to stop at en-route?). Using the faster Spanish train takes that down by 8.5%, 13 hours. Overnight+a little bit, that's pretty good! Obviously you can get a bed, full meals etc.

      But no :-( your government wants everyone to drive or fly. (Mine -- the UK -- currently isn't that much better outside of London. The current big transport issue is the expansion of Heathrow Airport, it's already the largest in the world but the government wants to make it 50% larger, to take 700000 flights (a year?). I'd rather see faster rail connections to mainland Europe from the rest of the UK, the reduced demand for short flights would free up space. It's still quicker to fly if you're going further than about Paris/Belgium, especially if you don't live very close to London since all the international trains can't go further north than London.)

        I happen to live just beside the LGV Est, and I have been working on the Spanish Madrid-Valladolid line. These are two amazing pieces of engineering, the new spanish line makes Madrid to Valladolid (211 km driving) in less than one hour, with one stop. The big advantages over flying are:

        - You don't have to be there more than 15 minutes in advance.
        - The train takes you to the center of the city.
        - You can have a train every 5 or 6 minutes, if there are a lot of passengers.
        - Much more fuel efficient. CO2 emiss

    $70bn really is not that much money - less than the Iraq war is costing us every year.

    But I wonder what the carbon footprint looks like? A plane at 35000 feet is in much thinner air and would not be able to fly LA to NY at a much lower altitude. The train will have to work in that thick air but will be a lot longer with presumably many more passengers and is not using aerodynamic lift. The propulsion system is also more energy efficient.

    So I have no idea which works out better. Anybody have numbers? One can of course argue that the maglev can use renewable energy, but that's a crock unless you have surplusses of renewable energy, which we don't.

      I have no idea about maglev, but conventional high speed rail (current best is about 350kph or 220mph) claims to be about 10 times less carbon producing than the flights it replaces -- i.e. relatively short distance flights. Long haul flights are more efficient, but the train still wins. Also, the plane puts crap into the upper atmosphere (bad!) but the train can put it anywhere, since you get to choose where to site the power plant. The maglev is flexible in it's energy. The wheeled train has the advantage that if prices get really bad they can just slow down to save fuel.

    Really. Giant mirrors in space beaming solar energy down via microwaves to the Sahara [Africa], Gobi [Mongolia], Empty Quarter {Saudi Arabia] or Sonoran [Arizona, USA] deserts (chosen for their lack of people and access to nearby large populations) instantly solves the energy crisis. And they [google.com] wouldn't be *that* expensive.

    The current projected price for an LA to SF conventional high-speed train is on the order of $30billion. That's for 500 miles and only going through the fairly small mountains around San Francisco.

    NY-LA is 5x as long, and has the freaking Rocky Mountains in the way. How exactly do they figure the $70bil price, even if it was a conventional high speed and not an exotic maglev?

    A maglev would be nice, but the kind of big money projects that intrigue me are semi-public works projects to make the country more disaster proof and help it adapt to global warming.

    Like:

    Water pipelines and catch basins to help the West deal with mountain snowpack that is starting to melt too early. Part of the deal: Subsidize cisterns for new homes.

    A survivable, redundant national energy grid.

    Equip cities with a hardened emergency energy and communication infrastructure to keep traffic signals, police stations, hospitals, and the like going during a crisis.

    I heard a terrific series of lectures by an ex concorde pilot this past summer. There were a few points about its demise that he made that I'd like to pass on:
    • Concorde was profitable right up to the end, even including the massive overhaul costs; in its final year, 7 relatively low-capacity aircraft made £90m, whilst BA as a whole was making a loss.
    • The only reason BA stopped flying them was that the French wouldn't let them - the agreement under which they were originally built stated that both countries had to to keep flying their concordes and the French didn't want to keep flying theirs because THEIRS were unprofitable (because they operated them badly)
    • Also, the French hold the type certificate on the plane, so BA couldn't go even build new ones.
    • The original agreement also stated that BOAC, later BA, had to operate the British concordes; so even if Beardy Branson had purchased them, they'd still have been operated by BA staff, and if BA were going to be operating them, they'd damn well still be doing it with the planes in their own colours. Except they couldn't - see above. It was a publicity stunt and Branson knew it.
    So, to conclude, the reason that the only supersonic airliner is sitting rotting on the tarmac is because the French killed it, not BA. Also, the Paris crash was caused by Air France putting too much luggage on board and then overfilling the fuel tanks to give it enough to get across the Atlantic. (The tanks were supposed to be 97% full, the French filled them to 100%.)

    New York - LA is not a good idea. The thing is, a Maglev could support a very large number of passengers per year, but its also very expensive, so it needs those passengers. To get so many passengers, you can't cater primarily to travellers, you need to cater to commuters, who will only start appearing if the travel time is less than one hour or something like that.

    But a maglev from Washington to New York via Baltimore and Philadelphia would be just over 200 miles, so a maglev going at 300 mph could easily do that in one hour. This would effectively tie these cities together and going between them could become an every day habit for millions. It would make the region the largest metropolitan area in the world and completely transform it.
