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.'"

Maglev On the Drawing Boards 334 comments
longacre sends along a Popular Mechanics article on the growing interest in magnetic levitation trains in the US. It's unclear how many will actually get built here, at $100 million per track mile. (In recent years we've discussed maglev projects in China and Germany.) The article has a map of many proposed transportation projects in the US, some of them maglev, and a video of a General Atomics maglev prototype in action. On a related note, an anonymous reader recommends this article on a proposed maglev wind-power turbine, said to offer the promise of replacing 1,000 conventional wind turbines.

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.

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

Carbon footprints? (Score:3, Interesting)
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.

Concorde (Score:5, Informative)
- 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 - Washington would be better (Score:5, Insightful)
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.

The government helped the railroads along with some prize money, loans, right of ways, etc. but it was not a government project to the extent the Interstate Highway system was. So yes it could be done as a mostly private sector project. And if it ever happens it will almost certainly be a private project that gets the deed done.
The problem is fighting the entrenched interests who would use the government to obstruct it. Don't ya think the railroads would like to come roaring back to the forefront of passenger transport instead of the pathetic government boondoggle called Amtrack?

They would only grant permission if the trains would stop at a station in their city. For every city, this would involve an extra ten minute delay added onto the journey, which would defeat the purpose of being faster than air travel.

That's a fine false dichotomy you've got there.

Of course, as it is, I don't believe Iraq was at all relevant to terrorism. By diverting our resources there we actually reduced our chances of catching a known terrorist. Further, a few simple and inexpensive precautions and procedure changes would have given us just as much (or more) security as the TSA and all the new metal detectors and xray machines have.
