Hyperloop One's Full-Scale Pod Reaches 192 MPH In New Nevada Track Test (techcrunch.com)

On July 29, 2017, Hyperloop One competed a test at its full-scale Nevada test track that travelled a high speed, running nearly the entirety of the 500 meter (1640 foot) test route. "XP-1, the company's first Hyperloop pod, reached speeds of up to 192 mph during the test, which is getting closer to the planned functional speeds of future Hyperloop installations planned for Dubai elsewhere," reports TechCrunch. From the report: The new test breaks the recorded speed record for any Hyperloop tests ever conducted, including those done by research organizations participating in SpaceX's pod design competition. It was conducted on July 29, 2017, and included a 300 meter acceleration phase, with gradual breaking to come to a stop after that point. Hyperloop One depressurized the tube for the test track down to conditions similar to those at 200,000 feet above sea level, which is part of the Earth's atmosphere where there is very little friction and resistance to the rarified air. The company says that all aspects of the system, from motors, to electronics, to the vacuum pump and magnetic levitation mechanism worked well during the test.

First LEP, then LHC, now Hyerloop

[John Allsup]

Not content with smashing elementary subatomic particles, not content even with accelerating protons or lead ions, now they want to accelerate people, inside long evacuated tubes, to ridiculous speeds.

Springfield is getting a monorail.

WOOHOO!!

Something new?

"New Nevada Track Test"

I'd like to welcome our most recent member - New Nevada, which joins New England, New Jersey, New York and New Mexico in making news!

No, no, no. it's:

NevadaTestTrack nevadaTestTrack = new NevadaTestTrack("Hyperloop One");

Vacuums suck

[ebonum]

They are expensive, temperamental, inefficient, and there is a reason scientists say "Nature abhors a vacuum".

All I can say is, "I want the contract to maintain the 1,000's of miles of vacuum tube!"

and there is a reason scientists say "Nature abhors a vacuum".

They do? 99.99999999999999999% of nature is hard vacuum. Just not where we want it.

Re:Vacuums suck

[sconeu]

The well known problems with full vacuum tubes are the entire point of the Hyperloop's design, which uses low pressure (1 millibar) instead of full vacuum.

This is why they should transistorize it instead of using vacuum tubes.

Dubai elsewhere?

[chuckugly]

I want to know where Dubai elsewhere can be found on the map.

Can't you editors even use the right word?

with gradual breaking to come to a stop

Goddamnit.. the word is braking.

Impressive acceleration

[Solandri]

v1^2 - v0^2 = 2ad
a = (v1^2 - v0^2) / 2d

v0 = 0
v1 = 192 MPH
d = 300 meters

a = (192 MPH)^2 / (2 * 300 meters) = 12.28 m/s^2
= 1.25 g
arctan (1.25 g / 1 g) = 51.3 degrees

That's gonna be trippy riding inside. Since there are no windows, you only have the apparent direction of gravity (acceleration) to determine "up". It's going to feel like you're in a plane climbing up at a 51 degree angle. That is, anyone trying to stand while this is going on is going to be leaned forward at 51 degrees relative to vertical at rest. (I'll add that the earlier test to 69 MPH in 30 meters is 1.68g, giving an apparent inclination of 58 degrees.)
