I consider myself a fairly good engineer. I built-a..hmm… well… anyway, I must have built something meaningful in the past a few years. I just can’t remember now. Maybe my “software engineer” title is an exaggeration, ‘cause when I am looking at this picture, there is just no comparison between my type of “engineering” and THIS type of engineering:
A magnetically levitated train takes you from New York to London in 54 minutes! You will go 5000 mph through a 3100 mile long tunnel that was itself floating in the Atlantic Ocean.
About a year ago, I saw this on the Discovery Channel. The hour long program explained theoretically how this will work which I still clearly remember. The main idea is simple. We can’t achieve high speed because of friction. With the air friction and the contact between the rail and the train itself, today’s engineering can only achieve about 200 miles per hour speed. In order to achieve 5000 mph speed, friction has to go away, meaning that the train has to flow and the tunnel can’t have air. So, what’s gonna happen? Use magnetic field and suck all the air out of the tunnel.
Discover website just put this Trans-Atlantic Tunnel project into an interactive tool. It’s pretty cool to check out it’s “Extreme Engineering” design. I don’t know if any giant company is funding this project or not. But if this theory can really become reality, I’d be tempted to find out how my guts would feel while traveling 5000 miles per hour… Hehehe… \

More importantly, how would your guts feel if the tube suffered a catastrophic rupture and your 5,000 mi/hr train hit a wall of water…

I have a name for this gizmo…”Underwater Tube of Supersonic Death.”
Hmm…That could be a punk band too.
It is nice to see that the designer included a “Vaccuum Pump” so they can keep the tunnel tidy.

“Oh, I’m a custodian in the Underwater Tube of Supersonic Death.”

Oh.. just a thought.. Concord travels at 1330 mph speed. Once the aircraft achieves that speed, shouldn’t the relative velocity be almost 0? So my guts should be fine if the object is traveling at either 500 mph or 5000mph as long as there is no sudden acceleration. But I wonder if my guts can take 0 - 5000 mph in 15 mins…. considering it takes 15 mins or so for the usual aircraft to reach 700 mph after departure???

ahh, yes, but…the velocity of the container (concord, UTSD, etc) relative to its passenger isn’t such a concern. It’s the velocity of the container (concord, UTSD) relative to the wall of water (the pilot that appreciates the clouds clearing only to be eye to eye with a mountain goat) that is of concern. i would be inclined to fear the deceleration more than the acceleration.

Yes.. the velocity of the container relative to the external object, whether it’s water or air is the greatest concern. But in this design, the train (which is the container in this case) has no contact with any entity. The tube is free of air, and the train flows by the magnetive field. The water is isolated outside of the tube and the tube will be supported by giant pillars. In this case, the tube is the one that needs to be strong enough to sustain shark attack, bugs, plate movement, underwater volcano or whatever that might cause Tube failure…
I still think tihs is a possible realistic design… if anybody has the money to fund it…
