San Francisco to Los Angeles in 30 minutes?

For his part, Musk is being coy about his latest pet project -- describing it in a recent interview as a crash-proof and weatherproof "cross between a Concorde, a railgun and an air hockey table." Hyperloop, he says, will be able to move people across the 350 or so miles between downtown Los Angeles and San Francisco in a half-hour.

As long as my sister-in-law is barred from access, I'm OK with this development.

A big tube?

 

[PhDeac]

Looks like it. A series of tubes in which human beings move really fast, much faster than we currently move through underground tubes.

I don't think most people could put up with the discomfort of going 700 mph for 30 minutes. Seems like a pretty silly idea.

While locked underground in a tube.

What discomfort? You just mean fear? Or are you implying some sort of physical discomfort that results from going fast?

 

[HailToTheDeacons]

"gets idea from futurama"

Yup.

While locked underground in a tube.

From what I posted, it looks like some could be in the air. Probably like most metro systems. Some in the air and some underground.

 

[Smidge]

Still sounds scary as hell, I mean imagine a break down or am accident at that speed in a tube.

Well we all knew we'd be traveling through the internet eventually.

You gonna make plans for Clips and Warriors doubleheader day?

that'd be sick

not sure who is my bigger hero, musk or haralabob. although tesla got pwned today.

I don't feel like doing the math, but, what kind of acceleration and deceleration would you have to experience in order to travel that quickly between those two places?

I mean I think they could work out the acceleration and deceleration on the front and back ends. Obviously once they reach a constant velocity there's not any acceleration, and I would imagine that they can get it up to speed slowly and decrease it slowly enough that you won't be thrown like the Aerosmith roller coaster.

Let me clarify. I don't know how to do either of these

I just meant that if we've figured out airplanes and acceleration in a variety of other areas, that we can probably work it out on this technology.

 

[RacerDeac]

At 1/2 G rate of constant acceleration (pretty comfortable IMO), it would only take about 1 minute to accelerate up to 700 mph. Same for decel. So you'd only have to spend a little over 2 minutes speeding up and slowing down. You could spend more time doing both, only adding a little more time to the trip, and make the accel/decel even more comfortable for the passengers.

 

[scooter84]

Yea, so I did a little math and the accel/decel is surprisingly minimal....

You can make it simple if you assume you just make the first half of the trip the exact opposite of the second half... That is, you accelerate at a constant rate for 15 minutes and cover 175 miles (half the goal time and half the distance) - then you decelerate at the same rate for the second half of the trip.

With these assumptions, the acceleration and deceleration required would only be like 0.7 m/s^2 - or less than 1/10th the acceleration of gravity. I don't even know if you would feel that?
