What: Submerged OCEANIC tunnel and supersonic train WHERE: New York London Cost: $88 billion $175 billion Crux: Neutrally buoyant vacuum tunnel submerged 150 to 300 feet beneath the Atlantic's surface and anchored to the seafloor, through which zips a magnetically levitated train at up to 4,000 mph.The idea is as wondrous as it is audacious: Get on a train at New York City's Penn Station and hit Paris, London or Brussels just an hour later. "From an engineering point of view there are no serious stumbling blocks," says Ernst Frankel, retired professor of ocean engineering at MIT.
...physic would be. Or more succintly stated it would be the human bodies reaction to extreme acceleration. Let's say you wanted to get to London from NY in one hour and wanted to get up to 4000mph in that distance... acceleration=(final velocity-initial velocity) / time a=(4000mph*5280ft/mile-0mph) / 18000 seconds (half an hour, we might need some time to deccelerate) a=21120000/1800=1,173 ft/s2 The gravitational pull of earth is 32.2 ft/s2 You would be pulling over 36 Gs for an hour (half during acceleration and half during decceleration). I hope you enjoy your show in London but I think you may need some medical attention as blood flow to your brain probably stopped about an hour ago.
