Elon is a genius engineer? 

I don't know about that.

Vertical powered rocket landings not enough to convince you? (He was chief designer for Falcon 1, perhaps by time of falcon 9 more supervising larger team but spends quite a bit of his time on design.)

I don't know that many engineers.  A couple I know are danged smart and inventive but haven't had the opportunity to take big ideas and run.  Elon's come to the game with unusual resources.

There are also some very stupid engineers.  It seems a lot of climate change deniers at least claim to be engineers. 

Perhaps they are sanitary engineers....

Ukraine has plans for a hyperloop
Quote
Ukraine is yet another country hopping on the hyperloop train to the future.

The country's Infrastructure Ministry signed an agreement Thursday with US-based Hyperloop Transportation Technologies to begin building a commercial hyperloop system -- a trainlike transportation setup that industry watchers say will be able to hit airplane speeds and shorten travel time from hours to minutes.

"Ukraine is at the crossroads of the new Silk Road transportation corridor and we can expect Hyperloop to play a major role in connecting Europe and Asia," HTT CEO Dirk Ahlborn said in a release. ...

Construction of the test route of 15km from Balewadi to Gahunje will start in 2019.

Mumbai-Pune hyperloop test track work may start in 2019
https://timesofindia.indiatimes.com/city/mumbai/mumbai-pune-hyperloop-test-track-work-may-start-in-2019/articleshow/64641200.cms

Below in blue is roughly the section of the route being discussed, shown on a road map.  Looks like a rather straight shot, if they follow that road, for their first section of the Mumai-Pune track.  (“22 minutes” is the current road travel time! :D )

Firms with local smart-city offices picked for Hyperloop One feasibility, environmental studies on Chicago-Columbus-Pittsburgh route
Quote
Los Angeles-based AECOM will take the lead the feasibility study for the hyperloop technology along two possible paths. It will look at how to apply the technology, passenger and cargo demand, economic benefits and costs, effect of regulations, implementation strategy and opinions of stakeholders including governments, businesses and the public. It would explore both the route along existing rail lines first proposed by MORPC and identify and alternative route. The study is expected to be complete next March.

Texas Officials Confirm Hyperloop As Technology Option For Dallas-Arlington-Ft. Worth High Speed Corridor
- Following Visits to the Virgin Hyperloop One Test Site in the Nevada Desert and its California Innovation Campus, the Dallas-Ft. Worth Regional Transportation Council Announces Intention to Evaluate Hyperloop Technology in Dallas-Arlington-Ft. Worth Project’s Environmental Impact Study
- The Agency Will Also Undertake Conceptual Feasibility Study Considering Hyperloop for Longer Fort Worth to Laredo Corridor
Quote
   Dallas, Arlington and Fort Worth Environmental Impact Statement
Later this year, the RTC will issue a Request for Proposals for a consultant team to complete the Tier 2 Environmental Impact Statement (EIS) for a high-speed corridor connecting Dallas, Arlington and Fort Worth. The RTC wants to consider both hyperloop technology and traditional high-speed rail in the environmental study of the route. A preliminary analysis by Virgin Hyperloop One engineers estimated a six minute hyperloop trip between Dallas and Ft. Worth.

“As our region grows from 7.2 million people now up to 11.2 million by 2045, we are planning a transportation system that offers choices to our residents. Adding an option like hyperloop to the existing system of roadways, rail transit, bicycle/pedestrian facilities and high-speed rail to Houston would expand the system in an exciting way,” said Michael Morris, P.E., Director of Transportation for the North Central Texas Council of Governments. “Connecting other regions in Texas through hyperloop would open up economic opportunities throughout the state.”​

   Fort Worth - Waco - Temple-Killeen - Austin - San Antonio - Laredo Feasibility Study
In addition, the RTC has provided funding and has obtained additional funding commitments to undertake a conceptual feasibility study of high-speed technology including hyperloop to connect Fort Worth, Waco, Temple-Killeen, Austin, San Antonio and Laredo. This corridor will be requested to move into a more detailed Tier 2 EIS following the feasibility study. ...

The tube was scaled down for the student competitions, for cost and logistical reasons, including transporting their projects to Hawthorne.  For prior competitons, some brought parts with them on the plane, and re-assembled their pod there!

One of the biggest obstacles is that the tube is only .8 miles long.  Achieving higher speeds in that short a distance is hard in itself.

Photos show Elon Musk closely examing the pods — probably getting his own ideas from the different techniques the students have employed....

Feasibility study delivers Kansas City-to-St. Louis hyperloop results. (Interestingly, it's the first time feasibility numbers have been released in the U.S. for a hyperloop system, according to a Hyperloop One spokesman.)

Hyperloop: Missouri could be epicenter for 21st-century transportation (Video)
Quote
Black & Veatch's release of its Missouri Hyperloop feasibility study is a "historic moment" for Missouri, Virgin Hyperloop One's Ryan Kelly told the Kansas City Business Journal. 

Not only does the feasibility study confirm the viability of a hyperloop route along Interstate 70, it's the first time feasibility numbers have been released in the U.S. for a hyperloop system, Hyperloop One's head of marketing and communications said.

The nine-month feasibility study conducted by Black & Veatch and Olsson Associates evaluated several aspects concerning the I-70 route that would connect Kansas City to Columbia and St. Louis, including social impact, potential station locations, route alignments, regulatory issues and rights-of-way access.
The study confirmed that the proposed route between St. Louis and Kansas City would shave travel time to 28 minutes. By car, it takes about 3.5 hours. Travel to Columbia from St. Louis or Kansas City would take about 15 minutes, compared with today's two hours.


Black & Veatch also identified potential station locations, known as portals, which could be located near downtown Kansas City along the riverfront or near Arrowhead and Kauffman stadiums, said Drew Thompson, Black & Veatch's director of data center/mission critical facility solutions and a project lead on the feasibility study. In St. Louis, an ideal location could be at Lambert International Airport, which also is a hub for light rail and bus transportation, Thompson said.

One of the most important aspects the study brought to light is ticket costs, which are expected to cost less than a high-speed rail ticket, Kelly said. A one-way hyperloop trip from Kansas City to St. Louis, for example, would be cheaper than driving when considering the average price of gasoline.  With gas prices currently at about $3 per gallon, it costs about $30 to drive to St. Louis. If prices continue to rise, the cost of 10 gallons of gas could rise above the predicted cost for a one-way hyperloop ticket — about $30.

The Missouri Department of Transportation also owns or manages the rights-of-way along I-70, which eases the path to construction.

Another compelling factor for Missouri is its central location, which could accelerate the build-out of a regional and eventually national network for transporting goods and people, Thompson said.

The study also found that less time spent on the road could result in a savings of $410 million a year and would lead to fewer accidents along I-70, creating an additional savings of as much as $91 million a year.

It's <240 freeway miles from St Louis to Kansas City. <24 mpg is poor highway mileage today. Perhaps they'recomparing the ticket price to what it would cost if you made the journey by Hummer? (the gas version does much worse, but a diesel version boasts 25 mpg highway!)

Personally my gasoline powered VW would make a round trip, them back to Columbia before I required a fill - up. :)  - and I don't have a 60 gal. tank.

I must say that is hardly the point. Short-haul flying costs more than driving and yet people fly. 30 minutes instead of 3.5 hours, I am sure there will be enough passengers for $30 each way. They simply picked a bad comparison. (In addition the true cost of driving is not just fuel.)
The real questions are - will the vacuum technology work? Will the construction and maintenance costs be reasonable with this technology? Will the ride feel indeed like a roller coaster? I guess we won't know for certain until someone builds an actual flight-speed hyperloop.

This plains states construction could be a good first project — it’s mostly flat, and the highway is already smoothed terrain.  But they will still need to dig out or elevate the tube over the ground as needed to keep the tube level.  They must have examined the route in detail and evaluated that, to come up with a price.  I hope they move forward with it.

California-based company HyperloopTT is officially scheduled to begin construction on the first commercial Hyperloop system in Abu Dhabi in the second half of 2019, according to a company press release.
...
When HyperloopTT said it was aiming to be “passenger ready” by 2019 during the capsule unveiling earlier this month, we were cautiously excited, as legislative hurdles can often ground projects before they get a chance to take off. With new backing, a regional partner, and a clearly defined timeline for next year, it certainly seems as though HyperloopTT is on track to get this system in place sooner rather than later.
http://www.thedrive.com/tech/24492/u-s-company-to-start-construction-on-abu-dhabi-hyperloop-track-in-2019

I recently attended a HyperloopTT presentation at an engineering conference.  Some interesting tidbits I learned:
  • Passive maglev in low pressure tubes
  • Elon Musk's design "does not work"
  • Acceleration will be limited to 0.5g
  • Two tubes, one for each direction
  • Working with Leybold on vacuum tech

Thanks sedziobs.
 
No doubt that Elon's design, with the air cushion skits and the compressor (spinning at 10x rpms of a turbine), shooting a spaceship through a barrel at the speed of sound was bat-shit crazy.

But what did HyperloopTT change so that it would work ?

There are significant other technical issues, which we discussed in this thread, which have not been addressed at all by the Hyperloop companies. For example :

- thermal expansion of the tube, a significant issue for any Hyperloop longer than a few miles.
- the Kantrowitz limit which will start to kick in at around 300 mph.
- the power source (and temperature control) of the pod

Did the HyperloopTT presentation address any of these issues ?

Meanwhile, since the current concept of Hyperloop is Maglev in a vacuum tube, it will be more expensive than Maglev without a tube. So why build a Hyperloop if plain Maglev is cheaper ?

This presentation outlines some more issues with Hyperloop :

The concept of maglev trains in an evacuated tunnel isn't new. A working model was demonstrated in 1914 by Boris Weinberg.

https://www.futilitycloset.com/2014/06/14/a-new-commute-2/

I think that thermal issues in the pod put the final spike in anything resembling Musk's vision of the Hyperloop. His own drawings featured a (very) high pressure steam container that was to be swapped out with fresh, cold water at every stop.

Shades of 19th century steam engines stopping every 50 miles to take on water.

No, unfortunately.  This was a civil engineering conference, so it focused on construction/geology and gave only a cursory review of the mechanical/electrical aspects.  The pods are supposed to be battery powered and made of carbon fiber that is lighter than aluminum and stronger than steel by an order of magnitude.  I don't know much else.  I'm interested to see how they address thermal expansion. Oil pipelines are deliberately laid out in successive curves that can accommodate expansion.  That won't work with a hyperloop.  I don't believe they use an air compressor, so larger tube size must be the plan to avoid the Kantrowitz limit.

After EUROLOOP, Hardt, Zeleros and Hyper Poland, another Elon Musk’s SpaceX Hyperloop Pod Competition participants decided to form a commercial company.

This time Denis Tudor, who was a founder of EPFLoop and a former member of rLoop Controls Team together with his colleague from EPFL Cyril Denereaz formed a company called Swisspod.

”We safely build the most efficient, cheapest and fastest Hyperloop solution. After 3 awarded Hyperloop prototypes, it is the time to take it seriously.” ...

Musk has now gone underground with his version.  That eliminates the thermal expansion and pod cooling problems.  It minimizes terrorist/yahoo damage. 

Going underground avoids most route acquisition problems.  Just put the tunnels under federal and state highways.  With their permission, of course.  The tunnels do not need to run side by side, they can be stacked one over another for as many levels as we would need.

The current approach is to start with lower speed (155 MPH) "Loops" which would function as very rapid, non-stop subway systems in crowded cities.  That would give Boring Company opportunity to develop faster and more efficient tunneling machines and work out a lot of the details.  Plus prove their concept. 

Recently a short Loop system was approved in Las Vegas and construction work is expected to begin soon.  A longer Loop is in the planning/permitting stage to connect Baltimore and Washington, DC.

Yes, that's a simple solution for the lower speed "loops". Higher speeds of 700+ mph will require significantly greater curve radii than those found on roadways. Limiting lateral acceleration to 0.5g at those speeds would require a curve radius of more than 11 miles. Current 300 mph maglev tracks in Asia have 5 mile radii. Highways with a 75 mph design speed can have radii of less than half a mile.

Limiting lateral acceleration to 0.5g at those speeds would require a curve radius of more than 11 miles. Current 300 mph maglev tracks in Asia have 5 mile radii. Highways with a 75 mph design speed can have radii of less than half a mile.

If the Loop works as expected then we should see a serious effort to build a hyperloop system using the same tunneling approach.  And that might take some eminent domain work to put together the sort of route that would be needed.

The same problem with routing high speed rail, highways, roads, and transmission lines exists.  But you've got to take land away from people that they were probably using.  And put in things they might not want to see.  Go deep with a hyperloop system and the worst you'd need to deal with would be water wells.  Awarded costs shouldn't be high.

Musk has now gone underground with his version.  That eliminates the thermal expansion and pod cooling problems.  It minimizes terrorist/yahoo damage. 


Musk's initial "vision" was to load a water tank and offload a sealed container of very high pressure steam at each stop. The pod draws a lot of kW and runs in an evacuated pipe. How does putting the pipe underground even address this issue?

BTW
Isn't the Las Vegas project a <1/8 mile non-hyper loop?

The initial propulsion ideas seem to have been scrapped.  But since Boring is not talking about building a hyperloop system at this point in time we don't know what Musk and engineering team is planning for their hyperloop approach.

For now Boring is building 'very rapid subway systems'.  Top speed is planned to be 155 MPH, not the ~700 MPH of a hyperloop system.  At the lower speed there's not the need to lower the air pressure in the tunnel.

I think Musk is bootstrapping a hyperloop system via lower speed Loop systems like he's done with Tesla and SpaceX.  Find an entry point at which innovation can create capital and use that capital to move up another level in order to gain more knowledge/experience and more capital.  A Loop system can be built quickly and start earning money.  The LA Loop is likely to be producing income this year and the LV Loop in 2021.  The Baltimore to Washington DC Loop may start construction soon.  These projects will give Boring Co. engineers opportunities to refine their tunnel boring machine technology, increasing tunneling speeds and lowering costs.

I expect to see serious talk of a Boring Co. hyperloop project within the next five years.  When Boring feels they have the technology nailed down they'll start serious talk with someone, somewhere about building their first hyperloop.

Ah, Thunderf00t. The Youtuber who knows a little about chemistry is considered a scientist now.

What's gonna be shared next? Harris or Peterson?

Yeah, what a slippery slope this Youtube thingy is...

No man. The hyperloop is real. I rode one to work yesterday. I got there 10x faster. Also, I'm a cyborg thanks to Neuralink. It really helps me drive my Tesla safely, cuz it accelerates so fast. And I make so much money now investing in Tesla stock that I was able to buy a ticket to Mars. So long you non-cyborg, earth-side LOSERS.

Why does the video show nothing but a rail system which just happens to be in a tube and skips of the difficult engineering problems of the vaccuum part a "hyperloop"? 

BAE has made a rail system which travels over Mach 7. I didn't see the "hyperloop" rail system break the sound barrier, so I guess it has at least 7x to go until it isn't a laggard.

Although, the kids did seem to cheer really good, so maybe it is legit.

That BAE system is a railgun.  That's for shooting missiles.  Far cry from rail transport.

Elon Musk says he wants a new 10km (six-mile) vacuum tunnel for his futuristic Hyperloop - ready for next year's speed-record competition.

Hyperloop aims to transport people in high-speed pods in underground tubes.

Mr Musk tweeted his plan after the Technical University of Munich set a new record for the fourth year running.

Its pod reached 463km/h (288mph) on the current test tube in the US, which runs for 1.6km straight. Mr Musk said the new vacuum tube would be curved.

It's about a hundred years since the first high speed models of maglev trains running in evacuated tunnels were demonstrated. Hyperloop may be many things, but futuristic isn't one of them.


Early Patents date back to 1799 in England for evacuated tube trains, and a Siberian by the name of Professor Boris Weinberg built an evacuated maglev model in 1909. His Popular Science article promised 500 MPH rides from San Francisco to New York City in 1917. Sound familiar?

Terry,

That’s like saying a jet aircraft is no more advanced than Orville and Wilbur’s flying machine.
Those historic trains did not run at anywhere near 463km/h (288mph).

Saudi Arabia wants to build a 35-km hyperloop test track and research its potential.

Saudi Arabia Looks to Build World’s First Long-Range Hyperloop Test Track In Partnership with Virgin Hyperloop One
Quote
LOS ANGELES, JULY 22, 2019 – Virgin Hyperloop One, the only hyperloop company in the world to successfully test its hyperloop technology at scale, today announced a development partnership with the Saudi Arabia’s Economic City Authority (ECA) to conduct a study to build the world’s longest test and certification hyperloop track, as well as a research and development center and hyperloop manufacturing facility north of Jeddah.

Today’s announcement took place this week at Virgin Hyperloop One’s Los Angeles headquarters during a visit from a senior delegation of Saudi Arabia’s Economic City Authority, led by Secretary-General Mohanud A. Helal. The study will focus on King Abdullah Economic City (KAEC), located 100 kilometers north of the Red Sea port of Jeddah. The project, which would include a 35-kilometer test and certification track, will create opportunities for the development of specific hyperloop technologies and develop local expertise in Saudi Arabia which be commercialized and scaled. The study will also facilitate the development of localized hyperloop supply chains and the acceleration of innovation clusters across the Kingdom.

“Our partnership with Virgin Hyperloop One is a matter of pride for us and all of Saudi Arabia,” said Secretary General Mohanud A. Helal. “As we continue to help deliver the strategic pillars of Vision 2030, technology transfer and high-tech job creation opportunities that this relationship will bring are fundamental to our progress as a nation and our efforts to create opportunities for our bright young people. Having hyperloop at King Abdullah Economic City is going to act as a catalyst for a Saudi Silicon Valley effect and galvanize our software development, high technology research, and manufacturing industries,” he added. ...

500 MPH was the projected speed according to the 1917 article. Did Wilbur ever design a plane to go that fast?


Those evacuated tube trains from the 18th century probably could be compared to the Wright's aircraft. but the Russian evacuated tube maglev of the early 20th century seems comparable to Musk's contemporary designs. - and Prof. Weinberg had a working model 110 years ago.


It's just not a new concept - let alone "futuristic".

The world is already more “futuristic,” after less than two decades of Musk’s efforts.  His advances in the next five years will make today’s accomplishments seem quaintly old-fashioned. 8)

Can you give me an example?


I'm not trying to be a smart ass.
Evacuated Tube Maglev and commercially built electric cars are >100 years old. Reusable rockets and rockets that landed on their tails have been around since the very early days of space exploration. PayPal was something he bought into, then got fired from the board before it was sold to Ebay. I was lighting my walk with cheap solar lights that ran through a battery pack before Elon left Africa. PV and batteries have been around since most here were kids.


I went to high school with a kid who was implanting electrodes into lab rats brains, recording the output - then playing their thoughts back to them. I'd hold up a pissed off cat, or unwrap some very stinky cheese and he'd record the results. That was in the early 60's when others were playing with human brains and electrodes at McGill!


He's one hell of a salesman, but he's far from the first to make big bucks using the gift of the gab.


What has Elon done in the last 20 years that qualifies as "futuristic" ie things that are actually new?

Terry,

Before SpaceX, there has never been a rocket that reached orbit (orbital velocity) and survived re-entry to land.  Let alone was launched to orbit and re-landed a second time.  Or a third time!

Tesla changed the electric vehicle universe, transformed EVs to be sexy, desirable, and widespread, and forced the entire industry to begin a transition it has resisted for decades.

Tesla installed what was the biggest grid-tied battery in the world in Australia, and changed the view of such an installation from impossible/unnecessary to one of being vital for grid resilience.


Just having an idea for something, or making a prototype, or doing something in a limited way or for a limited time, does not move the world forward.  I doubt a person afflicted with a neurological disease would agree to have your friend’s electrodes implanted in their brain!  Mass manufacturing of cars, or rockets, is a hundred times harder than making a prototype — witness all the EV startups going broke trying to bring their idea to market:  of all the attempts, none has survived since Ford.  Except for Tesla. 

If you don’t see the difference between what was then, and what is now, then I can’t explain it to you.  Google is your friend.

The technology existed for decades. There was no point in doing it. There still is no point in doing it. If it can safely be repeated 10 times over, then it will make sense.

Musk invented nothing (except a really strange rocket-fueled "green" cult).

India has advanced the world’s first passenger hyperloop system by deeming the Pune-Mumbai Hyperloop a public infrastructure project,

India has labeled hyperloop a public infrastructure project — here’s why that matters
Quote
Hyperloop, the futuristic and still theoretical transportation system that could someday propel people and packages at speeds of more than 600 miles per hour, has been designated a “public infrastructure project” by India lawmakers in the state of Maharashtra.

Wrapped in that government jargon is a valuable and notable outcome. The upshot: hyperloop is being treated like any other public infrastructure project such as bridges, roads and railways. In other words, hyperloop has been plucked out of niche, futuristic obscurity and given a government stamp of approval.
...
The hope is that India’s government will award the contract by the end of 2019, a VHO executive told TechCrunch. If that occurs, Phase 1 of the project — an 11.8 kilometer (or 7.3 mile) section — would begin in 2020.

The cost of building Phase 1 will be covered by DP World, which has committed $500 million to this section. The government is covering the cost and logistics of acquiring the land for the hyperloop.

Phase 1 will initially act as a certification track, which will be used to certify the hyperloop technology for passenger operations. VHO wants this certification track built and operating by 2024. If this section meets safety standards it will become part of the larger hyperloop line between Pune and Mumbai. ...

Will. I have been in Pune recently. They need infrastructure money for buses, trains and roads ( they are awfully crowded ) and not spend money on things like hyperloop. Really??? Most people have barely enough money to travel with autorickshaw or a scooter for a family of four. Ridiculous display of excessive wealth divide.
