Getting to that speed without flattening people like a pancake inside the capsule isn't the problem.
Accelerating vertically at the acceleration of gravity ("1G") would take you from 0 meters/sec to 6500kph (1806 meters/sec) in (1806 m/s)/(9.81 m/s^2) = 184 seconds, or about 3 minutes. At top speed, you're at a constant velocity, therefore no horizontal acceleration (only if travelling in a straight line).
But I can definitely see a lot of problems arising if something goes awry at that speed. The capsule breaking and you crashing at full speed = 100% chance of everyone in the capsule being liquefied.
Also, keeping thousands of miles of the tube in a vacuum is not a trivial task. Just the smallest air pockets in the tube = bad news.
Also, what if the capsule doesn't have a perfect seal? Would the passengers suffocate, or would there be a reliable source to generate enough oxygen?
What if there is a medical emergency? You can't just stop and get out. Or what if you've got mad gas and kill everyone with your methane, or get terrible unexpected indigestion? You're basically helpless prisoners for the duration of your travel.
Then again, you could drop your kid off at school in the morning, travel around the world in 6 hours, and be back before school is out. |

I've been drinking, whatever. Acton needs to sort this out for me. Physics degree, and all that.
I summon him. |
MATT HAS BEEN SUMMONED.
However, I've just got back from a stupid delay, courtesy of British Airways, so anything I contribute now will be irrelevant.
Because I'm faced.
Sober opinion due soon. Stay tuned. |

This would be great for humanity. Magnetic Levitation actually works.
China has a public Mag-Lev in Shanghi that runs at 431 kph.
It takes 7 minutes to go across the city.
Japan has built a test one that has reached 581 km/h (the worlds record for a train)
Normally with a car it takes 25 hours to go from Toronto to Miami.
With a car.
Multiply that by 5 and your looking at just 5 hours.
People could have the time and money to go to florida for the weekend in the winter based on current technology. |

Whoa!!! With a car!? |

It's 8265 Kilometers between Toronto and Rio De Janeiro.
With that vacuum-tube technology imagine doing a day trip in the middle of winter to a nice beach in South America and it only taking 2 hours to get there.
At the bare minimum I think we should be building normal transcontinental Mag-Levs in North America. (i.e. New York to Los Angeles)
People could afford long distance travel.
Were so behind Asia when it comes to high speed trains. Just like we haven't sent a man to the moon since 1972, our generation is lacking a vision for the future. Mankind needs to have a better vision for the 21st century. |

where as in airplanes ... |
Small errors in airplanes are almost never catastrophic. Things go wrong all the time and the vast majority of those planes land safely.
Explosive decompression is a load of that Hollywood has made everyone believe, just like cars exploding when they crash. 99.999999% of the time it doesn't happen. |

well, but when it goes wrong, lot of people die. I think this would be much safer then car or plane travel if developed correctly |

Awesome! Imagine what the scenery must be like at that speed, provided these tubes have transparent windows and whatnot. |
