Should there be a railroad train tunnel from Australia to Seattle for folks who have a fear of flying?
With bullet trains becoming more popular all the time, and these "mag-lev" trains of the future still being developed, don't you people think that someday there will be a gigantic tunnel for high speed trains that runs through the Pacific Ocean? They already have one between Great Britain and France, right? In my vision, this amazing railroad of the future would run (at about 423 miles per hour) between Sydney, Australia and Seattle, Washington, with a lovely 1-day stopover in Hawaii. Free hula dance shows, the works.

hahahahaha so funny

You do realize how hard that would be to stretch a single underwater train tunnel all the way across the Pacific Ocean don't you?

Flying bites, so a nice train ride would be great. But the speed could be much greater, even faster than a plane... A plane is limited by it's speed through the atmosphere, a large plane with a meaningful passenger carrying capacity is limited by aerodynamic drag. There's the "space hop" option, where the plane would skip along the top of the atmosphere, avoiding drag and able to fly much faster, but still not as comfortable as a train. Think 5,000 mph! Create a vacuum inside the train tunnel, no aerodynamic drag, and maglev propulsion. Fantastically expensive, but in some future with near unlimited energy and will, it is theoretically possible. See: http://en.wikipedia.org/wiki/Vactrain

It's a nice flight of fancy, but not realistic. The Discovery channel did a extreme engineering show on the possibility of a transatlantic tunnel - a much shorter trip. The show estimated that it would take a Billion tons of steel and 12 Trillion dollars. Your Aussie tunnel would cost say, 50 Trillion; or the Gross National product of the entire world 2 times over. I do not think it will happen. Much more likely, there would be a tunnel connecting Australia and Indonesia; then a land route all the way to the Bering strait. Keep dreaming...

In fact, such a tunnel is well under way. It will link up with the Sydney-Tokyo super-tunnel and the Perth-London AquaTrain. Once the New York-London AtlanTrak is complete in 2011, you will be able to circle the globe by train. Seattle was chosen because of the close cultural affinity between Washington State and New South Wales.

Who is behind the current UK-Russia friction
Who is behind the current UK-Russia friction?
It's gone so far that Russia has closed down the British Council offices in Russia. It was Britain who started it - over the execution in England of a Russian spy who'd switched to work for the UK. He was a dreadful individual - a traitor to his country and a homosexual - like so many people attracted to this kind of sneaky, dirty work. Britain refused to extradite him to Russia and made a ridiculous fuss, accusing Russia of great wickedness in doing the only thing left to them by Britain's intransigence. Of course it served their policy well of sucking up to America by winding Russia up, but was still illegal and provocative. Many thanks Bruce, Ned and Michelle, for your shrewd and interesting comments. Yes Bruce, it's so true, that international political attitudes mirror personal ones, so very true, and sad. It took Britain 250 years to get over their resentment at being thrashed by a bunch of farmers and now (led by Tony Bliar), we seem to have gone too far the other way! Ned, you really do speak from experience, on more than one level! Michele, I wish you could feel more sympathetic toward poor old Mother Russia. She's had such a lot of sheer misfortune for so long and now, when, under her greatest leader ever, she tries to be friendly, she gets her backside kicked again. This kind of treatment can only make matters worse, and cause the Ruskies really to become the nasty types America tried to make us believe they were during the cold war (and succeeded, didn't they Michelle ??). But they are not as defenseless as Bush thinks : their power is in fuel reserves, and EU, not US will suffer !!

International politics is like having neighbors. Some are good friends and invite you over to watch football and drink beer. The rest are just annoying, so you complain about the leaves from their trees falling on your yard and whether their fence is too close to your property line. Then you get together with your friends and you all speculate that they are really perverts or criminals, behind their backs. I think many politicians miss the cold war and want to start it up again. They want to convince the public to spend massive amounts of money on weapons that never see use and to ignore how bad things are at home because of how important it is to maintain unity in order to counter the Russian threat. The 'war against terrorism' just doesn't demand those big ticket weapon systems.

My theory though it has nothing to do with your question is that Russia especially Putnin wants Russia to be the center of attention and influence it once had when it was a world super power. Their 'perfect society' crashed and burned and the Russians are not good at the Demcracy thing and have no idea how to think for themselves as individuals rather than a collective. My wife is Russian and I have been there 3 times and it is just a big 3rd world country where 1% owns 99% of the wealth just like Mexico. Putnin is still calling the shots and Russia should not be a part of the G8. Why do people in England think they are the puppet of America? Do we not each benefit from our alliance? We are cousins and have similiar interests around the world.
