This is a moderator message, so I hope someone reads this.


Everyone has a right to post in any public thread, including this one. However over time it is clear the main poster in this thread has been questioned extensively and his personal circumstances been  quietly questioned.

I will put to everyone if you all did not react, and post, this thread would   not be current, or worried about.  Remember it is i the armchair expert - it's only a what if.  It is not mainstream, but a theory for now.  It does not need to be factual  and can stay as is - it is affecting no one as long as the poster stays here and not all over the forum as originally happened.

No one HAS to post here, unless one is up to just teasing, or stirring.  We do not need to judge the subject. We can simply dismiss it and move on.


So we can let it lie, can we not ?

( no discussion of my post here please, most of you can PM me if really needed )

Update:  Being human (!) I forgot to add that I am not targeting any post who has been in this thread. It has just been a general trend I have noticed - I do follow this thread as a Mod.

French TGV losing $3b per year
Japanese big maglev tunnels only 5m per day
Hyperloop insufficient capacity
Only Magtube the magnificent is the answer
Maybe the greens would make it their platform?

I do not understand why Hyperloop do not just build big trains to feed any residual air to the electrically powered jet compressor at the end of the tunnel like Magtube.

Some very smart people have investigated it and Swissmetro but neither of them have thought of this.

Yes there is a downside that trains would only leave on half hour frequency but as only one tunnel would be required the fare would be half.

Magtube is the only one that would be economically viable from the day it is finished as it is the only one that would go all the way killing the Sydney/Melbourne route by plane with income over $1b per year at least for the next 100 years.

Do you have numbers for this, or are you just pulling numbers out of a hat?

Show working.

The $1 billion will be from 10 million passengers per year paying $100 each. These are actually the most sensible figures in Eddy's plan, so I'm sure he'll be along any moment to show the working. Ask him to justify assumptions on construction costs (exactly the same per km as north west rail), maintenance (zero cost), security (zero cost), market penetration (100%) and you'll get a cut and past of his most recent post.

At present there are seven million people who travel by air between Sydney and Melbourne https://www.ausbt.com.au/sydney-melbourne-the-world-s-fifth-busiest-air-route and in ten years time when built I am guessing ten million paying on average $100 per ticket and that is where I get the $1b per year income.

According to this https://www.nti.com.au/intermediaries/distance-calculator.php Melbourne to Albury is 260 kilometres, Albury to Canberra is 219 kilometres and Canberra to Sydney is 247 kilometres a total of 726 kilometres and the NWRL which has the same size tunnel with the same TBM cost $38m per kilometre ($1.15b divided by 30 kilometres) which works out far less than $30b for the three single tunnels https://www.transport.nsw.gov.au/newsroom-and-events/media-releases/getting-on-job-115-billion-tunnelling-contract-on-north-west

By having the passing stations at Albury and Canberra it not only allows a one and a quarter hour ride between Sydney and Melbourne but puts Albury 15 minutes away from Melbourne and Canberra and Canberra 15 minutes away from Albury and Sydney growing them big enough to have their own international flights.

Magtube only has to be a bit cheaper than air travel to kill it as it would be more reliable not being dependent on fuel costs and weather indeed it can be built in any weather without disturbing anyone.

What I would dearly love to see is kids from the bush who are interested leaving school and training up to build train tunnels everywhere for future jobs maybe at ten times the speed with my Free face TBM https://3dwarehouse.sketchup.com/search.html?backendClass=both&q=free%20face%20TBM

Now come on, billy; you know as well as I do that it's futile asking Eddy to provide any solid evidence to back up his claims.

You guys read my post above, I advise you to do so.....
  eddyb Chief Train Controller

The previous link for people flying the Sydney to Melbourne route was 2012 but this January was 8.5 million so next January would not be far off 10 million

As the maglev train would only have the same air resistance as the Sydney metro it would only use the same amount of power which is 137GW per year up to 60MW plus the three 300kw compressors $1 million per year plus a couple of hundred staff so as there is very little maintanance with maglev there should be heaps of profit.

Could you elaborate on what you disagree about please.

This is the email I sent to the Greens today.




Hi

At present I believe there is 100,000 tonne of jet fuel used every year between Sydney and Melbourne while Magtube could have a 5.6m wide 4,000 seat train leaving Sydney and Melbourne every half hour and only cost $50 million per year to run.

To keep build cost down I suggest the northbound trains wait at Albury and Canberra for 15 minutes and vice versa so only three single 6m diameter tunnels are required.

At NWRL stage 1 costs it could be done for $35b with stage 2 costs it would be $65b but if the Free face TBM can achieve ten metres per hour it may be much less. https://3dwarehouse.sketchup.com/search.html?backendClass=entity&q=free%20face%20tbm

Where the Japanese maglev is limited to 500 kph by air resistance and Hyperloop needs compressors on every individual pod Magtube would have a jet compressor evacuating the one tonne of air that enters the tunnel with each train as it is pushed towards it.

Do not hesitate to email me with any questions you may have.

That's all I read; if I got this in my email inbox, you'd not only be laughed at, you'd be put on an email blacklist and marked as spam. This isn't you emailing your grandmother at the weekend.

Please, learn how to email people in a business situation:

- Value, what can you give them?
- Proposition, what is it you're proposing?
- Conceptualisation, include numbers.

Longer emails aren't necessarily bad.

When I read this I thought you meant I had sent it to you.


I have posted the concept to Infrastructure Australia and it is somewhere above but it was rejected even though they never even asked one question which makes me wonder what knowledge they have and are they all just too busy to really look into proposals.

This is their board http://infrastructureaustralia.gov.au/about/board.aspx

There is no point in building something that is limited to 500kph if Magtube could be built in ten years but if you think it may take 30 years then last century technology is the way to go.

Have tried but no response.


Eventually he will have to use trains where people can stand in tunnels due to expansion and g force on the surface.


He evidently has employed a top TBM engineer to just push the discs harder but the trick is to step the discs back to provide a second free face so instead of grinding bits out as big as your thumb you tear out pieces as big as your arm.

A Queensland university study found sometimes experts had to unlearn things to see things out of the box and what I suggest is backed up by young rock mechanics https://link.springer.com/article/10.1007/s00603-016-1053-6

DO NOT encourage the special person,use a brain and learn to leave some things alone.
