From the Times of London today


 


"The port of Hamburg is to build an experimental magnetic “hyperloop” track that could propel goods to their destination at speeds of up to 750mph and replace up to 4,100 lorryloads, the equivalent of about 102 tonnes, a day.


The technology, pioneered by Elon Musk, involves firing large carbon-fibre capsules through a tube containing an almost perfect vacuum to minimise air resistance."

Guessing that this is a copycat hyperloop. Rather than one that is actually going to be built by Elon Musk.

The proposed one to transport people will need extremely gentle curves to counteract the G-force from travelling at those kinds of speeds. Fragile goods would require the same also.

gzt: Where does it go to? inland port?

 

2000km. Hamburg - Berlin - Dresden - Nuremberg - Munich - Stuttgart - Frankfurt - Cologne - Hamburg





No backup, no pity. Anyway, RAID isn't one.

"The authorities of Germany’s biggest port in the city of Hamburg are looking into the feasibility of constructing a so-called hyperloop transport track that could be used to distribute cargo from the harbour to inland logistic hubs and the other way around, the Port of Hamburg Logistics Company(HHLA) says in a press release. Together with US company Hyperloop Transportation Technology, HHLA presented its plans to the public to construct a hyperloop test track by 2021.

 

According to an article by public broadcaster NDR, HHLA estimates costs of seven million euros for a hyperloop station at the harbour and about 20 million euros for every kilometre of the track."

Don't. Think. So.

That would also limit acceleration/deceleration. Two minutes and 12.5 miles of continuous 1G acceleration to get to 750mph, and the same to decelerate, so I guess minimum practical distance between stations is 25 miles.

 

Hopefully passenger pods are gimballed so that acceleration is always felt as "downward" by passengers and goods?

 

20M Euros/km is also a strong incentive for straight lines.

 

Edit: From https://www.tesla.com/sites/default/files/blog_attachments/hyperloop_alpha3.pdf

 

Planned acceleration/decelerations are 1G. No gimballing fore/aft, so deceleration will be like standing hard on your car brakes for 2 minutes.

 

 

For aerodynamic efficiency, the speed of a capsule in the Hyperloop is typically: 300 mph (480 kph) where local geography necessitates a tube bend radii < 1.0 mile (1.6 km) - 760 mph (1,220 kph) where local geography allows a tube bend > 3.0 miles (4.8 km) or where local geography permits a straight tube. These bend radii have been calculated so that the passenger does not experience inertial accelerations that exceed 0.5g. This is deemed the maximum inertial acceleration that can be comfortably sustained by humans for short periods. To further reduce the inertial acceleration experienced by passengers, the capsule and/or tube will incorporate a mechanism that will allow a de gree of ‘banking’
