Title: Maglev Highways
Post by: kernals12 on August 22, 2024, 06:11:48 PM
2 years ago, a Chinese university released
footage (https://www.motor1.com/news/610621/china-tests-flying-car-that-hovers-using-magnets/) of an experimental magnetic levitating automobile bobbing along only inches above the ground. Supposedly they managed speeds of up to 143 mph. Could this herald a future of automobiles travelling between cities at triple digit speeds while maintaining the convenience of the car?

Stopping sight distance, effects of acceleration and deceleration (and turning) on the human body, being able to read signs at speed, etc.

I think it's a given that such cars would be self-driving.

Probably not.  But if you keep suggesting every experimental piece of technology is the next big thing you'll be bound to be right once eventually.

Given enough time, any technology demonstrated in a laboratory will be commercialized unless some other technology renders it obsolete along the way.

Convenient for you to fling infinite darts about what the next big thing is.  I don't get the angle about always trying to make predictions?  By the time you get one right your accuracy of prediction is still going to be skewing low. 

Why not just link these articles for us to see and leave hyperbole out?

Fair enough, thing is that you don't present any of these threads as such.  All well and good to ponder over stuff like new tech.  Quite another to try to make accurate predictions on what will catch on.

So if I start including qualifiers of 'could' and 'if' you'll stop dumping on my ideas?

Likely wouldn't hurt those chances.  Although the fact you say "my ideas" kind makes me wonder how grounded in reality this end product will be?

Interrupting the Max-Kern fight, it's a ridiculous proposition from the get-go. A maglev car would require a ferrous roadway while lots of states are converting mileage back to gravel.

Are you saying iron is too expensive to make roads?

There's a lot to unpack with that question. We have railroads obviously, but a freight train is restricted to those rails (unless you have a sister that's ugly, as the joke goes.)

Maybe one day a future RJ Reynolds will develop a surface that is cost-effective and has the physical capacity to support lifting a 3-ton SUV off God's ground. Wake me from my dirt nap when that happens.

Yeah, this aint happening. It will be too expensive to retrofit roads for this. It is much more likely that current self-driving technology improves to the point where speed and safety can both increase.

Even with autonomy, there's only so much speed you can get within the limits of rubber tires which have limited grip, lots of rolling resistance, and create a lot of noise.

And I don't see why this would inherently be too expensive.

Because you would have to eventually repave every road with a more expensive product.

The chances of rubber tire technology improving are much higher.

A. You wouldn't need to repave *every* road, you would probably only need a network slightly shorter than our current 67,000 mile system of controlled access highways that would connect every city, with travel within cities handled by ordinary non-magnetic roads

B. Aluminum may cost more than asphalt pound for pound, but it would last a lot longer especially without any direct contact by traffic.

So now you would need to build cars with tires and maglev technology. Sounds expensive.

Like many of your ideas, it's simply not feasible.
