My son in law says people who say it cannot be done should just get out of the way of those doing it.

Or did you just see that exact statement in my signature? (it been there for over 3 years!)

Well he's just as silly as you. You're not doing it, and he's not doing it.
The list of items posted by billybaxter is obviously something that you and your son in law just do not understand. Dismissing it with a flippant remark, indicates beyond any doubt that you (and your son in law) haven't the slightest idea what you're talking about. It's complex engineering; not something dreamed up in a mine by someone who does not understand engineering at all.

As Ken says "people who say it cannot be done should just get out of the way of those doing it"

You'd better ask whoever wrote that letter to clarify it because your description of its contents makes no sense. So you admit that despite your great efforts to get some interest in this project, not one person has written to you to say they think it's a good idea. Does that tell you anything?

It tells me that thanks to feedback from good people like you on different forums Magtube now is quite viable and I believe that any problems in the past have all been addressed. Some people who have openly opposed it for whatever reason will double down on their opposition and some are sitting on the fence.

So you've addressed the following list from 'rain shadow' at the Ars Technica forum

back-of-the-envelope calculations on velocity or pressure are not proof of feasability of the overall system. not even close. anything of this scale will probably need 10K pages of detailed engineering analysis including EVERY ASPECT not just the ones that we are bringing up. off the top of my head:

* thermal behahvior and limits of every single part, piece, fastener, assembly, and installation
* electrical power consumption, delivery, heat dissipation
* signalling, block control, deadman/failsafes, fire suppression systems, intrusion detection, leak detection, chemical/biological detection, earthquake/flood detection and of course some sort of plan for what exactly to do when something is detected
* management of and inspection for metal fatigue from pressure and temperature changes, vibration, age, oxidation, spalling
* serviceability of every single part
* management of static loads and dynamic stress on every structural part, whether moving or not
* unbalanced loads (i.e. all the passengers move to one side to avoid or gawk at something, or all start dancing to a popular tune and setting up a cabin resonance)
* human health and safety at every stage from walking into the terminal, or buying a bottle of water, or barrelling down the track, or vomiting into a barf bag, or having a heart attack 500 km from the nearest station
* hardening against terrorism, disgruntled workers and customers, unintentional chemical/temperature/pressure events from carry on consumer products, wildlife, exterior situations like 50C heatwaves, -40C cold, above ground issues like damage from car accidents impinging on the tube's structure or reinforcement
* provisions for smokers, pets, disabled, preferred customers, odd size cargo, inspection/maintenance vehicles
* proper attitude towards and management of stakeholder needs: regulatory approvals, right of way restrictions, insurance requirements, architectural conventions for light/space/color of terminals and carriages, psychological limits of customers stuck in a tube, PR for when things go wrong
* dynamics of financing. changing tolerance for risk after unrelated events, interest rate shifts for different financing stages throughout project, economic downturn decimates ridership expectations, executive turmoil/scandal
* perhaps the most subtle but maybe most critical point is that systems like this are vertically integrated--essentially a monopoly, as allowing quantas or united to drive their carriages down your tracks would be bizarre and introduce a layer of complexity that might doom the project. however, the internal competition within the airline industry has often been its savior. inefficient airlines can fail and the system of air travel continues. but if a vertically integrated transit system fails, only government intervention can save it, and then you end up with something more like amtrack and less like hopping onto expedia and having 100 ways to get from point A to point B for $149.

really, i'm sure the above doesn't even cover 1% of the issues involved in bringing a large infrastructure project to life.

so far it sounds most similar to a mix of an airport terminal and a metro subway, but with much longer distances and much higher speeds. given that metro systems are horrifically expensive already, adding more speed and distance just takes something that is already 10's of billions and makes it 100's of billions.

Eddy, You have laughed at a couple of items billybaxter listed, and completely ignored all the rest.  Have all the laughs you like, and then just give up - you really haven't got a clue about the detail design of any Magtube.

You would have ten years to work out detailed designs.

When you plan a holiday you do not decide what toothpaste etc. to take.

By the way what do you think would prevent it as you have not said anything yet and as far as people looking out the windows it would have none.

Which you couldn't do, and about which you know nothing. How would you know 10 years is correct?

Of course not - I already know.

By the way what do you think would prevent it as you have not said anything yet and as far as people looking out the windows it would have none.

What on earth are you talking about?

Well without windows I cannot see what else people may be gawking at.

What are you smoking, Eddy? I think when you wrote this you were dreaming of something else.

Sent you a pm

Sent you a pmNo you haven't!

Lies, lies and more lies from Eddy, the King of Liars. I didn't say that 'off the top of my head' at all. As I clearly stated, a poster called rain shadow on the ars technica board wrote that list and I quoted it. If you want a civil discussion Eddy I suggest you stop putting words into people's mouths. I notice that on that board, just like here, you completely ignored any questions or issues that people raised that didn't correspond with your preconceived notions. People made serious points about the finance and engineering aspects of your project and you just badmouthed them then ran away claiming they didn't understand local conditions, as if physics, economics, human behaviour and the laws of nature work completely differently in Australia. Have you received even one response from anybody yet? And a handwritten letter from the 35 years ago, or a robot generated form email don't count. Or is this question going to be added to the long long list that you refuse to answer?

I've tried,  billybaxter's tried, Pressman's tried, and none of us can get a straight honest answer from Eddy. Why would anyone would believe anything he says?
Facts don't interest him; fairy stories do.

"Sent you a pm"

No you haven't!

Yes I did

What do you want to know

well you didn't send it to my nickname,
I've received nothing from you,

My last received PM was on 20th Sept and was from dthead regarding a spam post I reported.

What do you want to know

Nice try Eddy. You know, and we know, that's there no point in asking questions, because you ignore them. You're living in fairy land.
