Nice idea, but who is offering to pay the simply eye watering amount it would cost? Most governments are battling big deficits, so don't look to them to fund it as borrowing the money would triple the already massive interest bill they need to pay on their huge debt load.
Then of course there's the concern that many things that work well in theory and in computer simulations, don't work so well when tried out in the real world.
Thanks I am glad you like the idea rather than thinking it is just some sort of fantastic joke.
Assuming it would beat planes in every way and have the monopoly of 5m people who travel between Sydney and Melbourne each year a fare price of $100 per passenger would make $500m per year.
If it costs the same as the NWRL @ $38m per kilometre that totals $30b plus $1b for the steel tube.
Interest @ 1% p/a on $31b =$310m
That leaves $190m for the Supertrain and running costs never mind the potential value capture in the four proposed cities.
I may be wrong but I think the world is back like the depression but I do not believe we need a war to get things going again all it needs for governments to start doing stuff rather than cutting just to keep the stupid AAA rating that only helps the banks to get cheap money from overseas to lend to negative investors pushing up the price of houses.
Actually I heard a guy on the radio say if we lose it interest rates may go to helping super funds and many retirees and I would add to that more Aussie jobs = more taxable income
So how about printing the extra money as is needed as it is a real investment perhaps giving unemployed engineers a job with the potential to export the world first technology later.
