Talk:Hyperloop pod competition

Article needs a better more descriptive image (or two)

This article really needs an image of the cross-section of the Hypertube test track. Note that this is not the same as any of the original Hyperloop concept drawings (as currently in the article) as the Hypertube test track has a number of different features that are not, strictly speaking, pure Hyperloop, in order to encourage both greater freedom in the pod designs conceived by student teams for the competition, and also in order to better test specific Hyperloop subsystems that are not a part of a complete Hyperloop-compliant pod design.

This sort of image could be created from information/drawings in the <ref name=uw20160108> source. Moreover, once the route becomes known, a plan view of the track in Hawthorne, California near SpaceX would be helpful. Adding a {reqimage} template. N2e (talk) 16:14, 2 February 2016 (UTC)

Here are the SpaceX specs: https://badgerloop.com/documents/TubeSpecs.pdf with the cross section on page 5. Of course, we can't just copy that for copyvio reasons. Or can we, since Musk released all Hyperloop stuff to the public domain? If we're not allowed to just copy it then somebody can make their own diagram based on it.  Stepho  talk  05:20, 3 February 2016 (UTC)

That's a good question... it is a SpaceX doc, and SpaceX and Musk have been explicit about all Hyperloop IP being open source. Hmmm.

We should ask Huntster for a learned opinion on the matter. (But I'm with you Stepho, we would be better served in the long term if someone would gin up a good graphic from that TubeSpecs pdf that is "made for Wikipedia".) Cheers. N2e (talk) 06:39, 3 February 2016 (UTC)

Sorry for the very belated reply. While Musk released the material to the public, did he actually release it into the public domain, i.e. released it from copyright? If not, then we cannot simply take it. However, strict numbers aren't really copyrightable, so there's no harm in making a graphic from scratch using published figures. We just need to find someone talented! — Huntster (t @ c) 07:01, 14 February 2016 (UTC)

I ginned up a quick and dirty image for the cross-section of the Hypertube prototype test track, and added it to the article. Have uploaded two versions to Wikimedia: one with English labels, and one without. Have added the one with labels, for now, to the article, since we haven't anything better. Removed the {reqimage} template from the Talk page; although I'm fine with someone adding it back if other think more/different images are required. Note to Huntster and Stepho Feel free to improve, fix, annotate, etc. Cheers. N2e (talk) 20:18, 8 March 2016 (UTC)

WaterloopCompetitionHyperloopPod

Finally, we have a decent image with the proper license compatible with Wikipedia. This image, is of one particular team's pod, and has a render with a clear tube, but it is definitely much better than anything else we've had that would be both Hyperrloopish, and related to the pod competition. So I will add it as the first image in the article now, which will make the article look much better later today when the Hyperloop pod competition article is scheduled to be featured on the Wikipedia Main page (I think in about 12 hours time). N2e (talk) 04:28, 14 March 2016 (UTC)

Date format

Ne2, since you are the first and most prolific contributor, can you choose a date format for the references. The current mish-mash of formats will surely flag it as a fail for Did-you-know.  Stepho  talk  01:11, 4 February 2016 (UTC)

Sure. In this case, I already have. I put a {{use dmy dates|date=January 2016}} statement in the article. If I write the dates out, I always use that format. If I use a ref formatter (like, e.g., https://tools.wmflabs.org/makeref/) to create a citation, I just accept whatever format it gives.

So for the prose, I think the dates are already (or 95%+) in dmy format. For citations, I don't worry too much because, as long as the use dmy ... template is set, some bot will catch the cites and make the dates more consistent in the next month or two. On the other hand, anyone is welcome to manually do that as well.

Hope that explanation is helpful. And, BTW, I don't think the DYK checks will care. They are fine with new articles that are still being worked on. In fact, the DYK for an article like this will probably bring so many folks to the article, one may be an editor who really cares about running tools that standardizes date formats. Cheers.

More competition results

Just found this source (http://hyperloop.tamu.edu/news-release-january-30-2016/) which provides a list of all the awards for the various subsystems. Many of these teams did not advance, but they won awards in the Jan 2016 competition that were apparently not covered by the press articles previously seen. Several more awards are from non-US teams and universities. Some of this could be used to improve the article. N2e (talk) 04:14, 5 February 2016 (UTC)

 Done—used source to update for the other awards. N2e (talk) 21:53, 5 February 2016 (UTC)

Vehicle Pods Expansion

This is a rough draft for a possible addition to the Vehicle Pods section.

Two different variations of the vehicle pod designs are being explored. One Pod design uses Mag-Lev; this design is used by the winner of the “Best Overall Design Award” MIT. The other major design variation is the air bearing design. This design relies on a system to create a bed of air for the Pod to glide on. This is the basis of Elon Musk’s original Hyperloop idea. The inside design of the pods vary by team. Some of the teams are solely building pods designed for cargo transport. Other teams are building pods to transport passengers, while other designs would allow adjustments to be made to the pod to allow both.

--Kyakid (talk) 03:26, 24 February 2016 (UTC)

That's a great start to stub out that section. I do note, however, that in addition to the mag-lev and air-bearing designs of various teams, at least one of the teams I've seen seems to be doing a wheel-only suspension, which would utilize the concrete base of the particular (and very flexible) Hypertube test track that SpaceX is building for the competition. After that, just be sure you add (or reuse) citations to support any statements you make, to ensure WP:V via WP:RS. Cheers. N2e (talk) 04:53, 24 February 2016 (UTC)

I would suggest giving a brief description of the Mag-Lev design, similar to the way you elaborated on the bearing design. ItsJeffers (talk) 16:11, 24 February 2016 (UTC)

added to the second part of pod competition

There are three hyperloop test tracks in the design and planning stages. AECOM, a global infrastructure firm, has proposed to build a one-mile track in Los Angeles at the Musk’s SpaceX company headquarters. There is not enough space for this track particularly, so it may have to be built crossing streets and through surrounding buildings. Hyperloop Transportation Technologies’ also has plans to break ground on a 5-mile track in California’s Quay Valley by the end of this year. In addition, a startup company called Hyperloop Technologies Inc. plans to have another test track in North Las Vegas, Nevada. — Preceding unsigned comment added by 13eccole (talk • contribs) 15:27, 24 February 2016 (UTC)

Link worked and seem credible. The wording of "built crossing streets" seems a little odd to me. Other than that, the paragraph is clear and informative. Khanine (talk) 16:04, 24 February 2016 (UTC)

Only the one specific track of about 1 mile in length, being built in Los Angeles, has anything at all to do with the Hyperloop pod competition. The other stuff, on other tracks, fits in the company-specific articles (see Category:Hyperloop), or maybe a summary of it in the Hyperloop article. It is simply out-of-scope for the Hyperloop pod competition article. Cheers. N2e (talk) 18:46, 24 February 2016 (UTC)

 Fixed—removed the bits on the tracks that are not related to the Hyperloop pod competition. N2e (talk) 23:41, 29 February 2016 (UTC)

Wheeled suspension: Team Cheetah

Looking for new hits on Google with hyperloop pod competition hits from the past few weeks, ran into this team (Team Cheetah) focusing on wheeled concepts (which Musk did allow, in jan 2016, might be the best option for the nearterm; even though only one or two teams proposed such) and external compression (no rotating, in-line air-compressor as in Hyperloop alpha design doc). Not sure where it would fit in the article, so will leave the link here. N2e (talk) 22:31, 7 March 2016 (UTC)

Email to hyperloop teams

In order to obtain more info to improve the article, but only from verifiably sourced locations by Wikipedia standards, I have sent the following email to as many of the pod competition teams (those that are moving on to phase 2 ) as I can locate an email address for.

Not all teams have email addresses, some have Twitter or Facebook links only, so if someone else wants to ping them via those means, pointing them to a link to this Talk page section, that would no doubt get the invitation for sourced info on pods spread just a bit more widely. Cheers. N2e (talk) 13:36, 12 March 2016 (UTC)

Subject: Hyperloop pod competition and Wikipedia

Good day,

The Hyperloop pod competition has an article on the English Wikipedia <https://en.wikipedia.org/wiki/Hyperloop_pod_competition>, by the same name, of course. Your team is mentioned there. Congratulations on your success so far in this prize competition!

Importantly, in the next 48 hours or so, that article will be one of the featured articles on the Wikipedia Main Page, in the "Did you know ..." section <https://en.wikipedia.org/wiki/Main_Page>. This placement will typically drive 5000 to 8000 hits to the featured page during the half-day or so that it is featured on the Main Page.

Should you want to ensure your team information is current/updated/improved, please add any relevant short summary of characteristics of your vehicle, along with a source that fully supports each of those characteristics, to a NEW section of the Talk page for the Hyperloop pod competition article <https://en.wikipedia.org/wiki/Talk:Hyperloop_pod_competition>. The link direct to the section that discusses this email is here.

Due to Wikipedia's strict rules on conflict-of-interest editing <https://en.wikipedia.org/wiki/Wikipedia:Conflict_of_interest>, you should not, in general, add your material directly to the HPC article itself since you are affiliated with one of the HPC teams. Adding info to the Talk page will allow non-involved editors to quickly assess the material, and summarize the content to add it to the article, adding a link to the source or sources you provide, assuming they are good sources and do, in fact, support the summary.

If you want to make it really easy for an editor to add your information, add your source in already-formatted wikicode by using this handy makeref tool to create your citation: https://tools.wmflabs.org/makeref/ -- then copy the ref wikicode and paste it to follow the short summary of characteristics you add to the Talk page.

Responding to this on Wikipedia is, of course, totally optional. But I just wanted you to be aware, and have the best shot possible of having your team and pod accurately represented on Wikipedia in the Hyperloop pod competition article.

Cheers,

"N2e" (on Wikipedia)

rLoop team and pod

rLoop is a non-profit, open-source, online think tank comprised of over 150+ members from diverse technical backgrounds representing more than 14+ countries working together to build a sub scale hyperloop pod named rPod, weighing almost 340 Kg, it is 3.8 meters long, 1.25 meters high and the aeroshell diameter is 1 meter. The pressure vessel in the rPod is made up of aerospace grade aluminum (AL 6061 T6) and it meets the commercial airline requirements of FAA, 14 CFR Part 25 Air Worthiness standards and has two dome style bulkheads for accommodating the non-vacuum rated components and the passenger dummy provided by SpaceX. The Aeroshell is made of vacuum compliant epoxy. rPod uses hover engines from ArxPax for levitation, They'll also be gimballed to provide thrust and braking. Albeit, the main braking system employs eddy current braking mechanism with a fail safe mechanism and an alignment system for Yaw control. — Preceding unsigned comment added by Vandaso (talk • contribs) 14:23, 13 March 2016 (UTC)

Thanks @Vandaso:. With sources, an abbreviated synopsis—something appropriate for the bullet list format of the Competing teams section, with only the key highlights—of that will be able to immediately move into the Hpc artcle. Do you have reliable secondary sources to support the key characteristics on the pod? Btw, I think that the scope of the team itself, 150+ members from 14 countries is probably relevant for the short synopsis also, as well as interesting to the gobal readership of Wikipedia. Cheers. N2e (talk) 18:03, 13 March 2016 (UTC)

Thanks @N2e:

Everything related to the key characteristics of the pod are on the technical section of the page I wrote. ( Forbes article and videos )

Regarding the synopsis, where should I write it? Should it be written in my draft then submitted or directly in the Hpc article?

Thank you for your help!

Vandaso (talk) 18:36, 13 March 2016 (UTC)

I think that the best place for you to draft that terse synopsis is right here, on this Talk page, since it deals with this article. Add the sources too, in the citation format you'll get from the makeref link I mentioned earlier on this page, and you will make it very easy and quick to get someone to update the Hpc page with your info (even before the Did you know...? goes live now scheduled for about Noon UTC tomorrow, on 14 March, about 8am I think in the east coast of the US).

Improvement of the article you mentioned on my Talk page is an entirely different matter, and probably best discussed whereever that draft is being worked now. Cheers. N2e (talk) 19:09, 13 March 2016 (UTC)

Thanks @N2e: Below is the draft summary of rLoop's description for the main Hpc page for your review.

• rLoop (the only non-student team advanced in the competition) is a non-profit, open-source think tank born on social media platform Reddit. Over 300 members with diverse technical backgrounds, from 15 countries, joined the movement since its creation in 2015. The manufacturing of the subscale Pod called rPod comes from crowdfunding, which closely mirrors the rLoop team spirit by relying on the collective effort of individuals. rLoop also intends to continue development of a full scale Hyperloop pod, named hPod, upon completion of the SpaceX competition.

Vandaso (talk) 19:49, 13 March 2016 (UTC)

Here's a modified draft of that, edited to leave only the most pertinent info, since it is headed for a bullet list with 30 teams in it:

• • Team rLoop, the only non-student team that advanced in the competition,, organized on social media platform Reddit. Over 300 members with diverse technical backgrounds, from 15 countries. Building a ___kg subscale Pod called rPod, using ___________ suspension and ________ propulsion.

Since there is only approx. 6 hours until this article goes live with a link from the Wikipedia mainpage, I'm going to just work with what I have. Don't have pod mass (from a source I could find), suspension, propulsion. I have updated the article. Fixes later. N2e (talk) 06:17, 14 March 2016 (UTC)

Waterloop (a.k.a. uWaterloo Hyperloop)

Waterloop is a Canadian team of University of Waterloo students designing with a minimalist strategy and strict safety considerations, resulting in a reduction in the manufacturing complexity, cost and mass; while simultaneously permitting an effective travel speed and increased reliability. Their 680kg pod is expected to maintain a cruising velocity of 9.8m/s and deliver a payload of 2300kg. The team is actively developing a conceptual design to demonstrate their vision of the competition design at full scale. Mrdeluna (talk) 01:38, 14 March 2016 (UTC)

References

Thanks, Mrdeluna. I left out the qualitative design goals and the post-pod-competition speculation, focusing on the pod design. Do you have suspension type and propulsion type that you could add here (I'm slammed now so don't have time to go through your pdf at present.) For now, I left the Canadian point; but I can see how it may be a less-than-fully-global Wiki-great perspective by listing county only for the non-US teams. But given time pressures today, this Talk page can debate that some other time. I also caugth an error: the pdf says 98 m/s, not 9.8 m/s cruise velocity.

Here's what I added to the bullet in the article: "Waterloop, a Canadian team designing a pod with empty mass targeted at 680 kg (1,500 lb) aiming for a cruising velocity of 98 m/s (350 km/h) while carrying a payload of 2,300 kg (5,100 lb). University of Waterloo"

Mrdeluna I do not have the time to fix it now, but if you would care to clarify some of the key subsystem characteristics in tight prose, with a source, I think it would get right in to the article. I saw some March document somewhere that seemed to summarize all that for your team. N2e (talk) 16:35, 14 March 2016 (UTC)

Article image

With the addition of a new appropriately-wiki-licensed image of a pod in a single-tube track, I have used that image quickly as the best image we have. (It is of the Waterloop pod.) However, I think that image could use a crop, if someone is willing to do that in the next 12 hours or so, since THIS article Hyperloop pod competition will go live on the Wikipedia main page for half a day in 7 hours time (at 12 noon UTC on 14 March, or 8:00 am east coast US time).

I think a crop would make that image better as a the main image for the article, as it would remove some blurry detail, and give a larger pod when the image is sized as normal on the article page. Also, if someone is good at wiki-images, you might want to play with getting the whole thing to display a bit bigger than "thumb"nail size. Cheers. N2e (talk) 04:47, 14 March 2016 (UTC)

He left this message on my Talk page: "... [The image] is now cropped and updated in the competition talk page. I unfortunately don't know the convention for best formatting of the image -- it would be better to me if it had a caption as in the framed formatting, but then it requires uploading a low-resolution image so that it doesn't fill the page. Do you have a suggestion for this? Mrdeluna (talk) 06:04, 14 March 2016 (UTC)

I've added the cropped image to the article page. But I cannot get it to display BOTH larger than "thumb" AND with the caption displaying. N2e (talk) 06:58, 14 March 2016 (UTC)

BadgerLoop

BadgerLoop is the University of Wisconsin-Maidson's entrant into the Hyperloop Pod competition. Composed of over 120 undergraduate and graduate students, BadgerLoop is a non-profit, educational entity lead by a majority of undergraduates.

Using Halbach array magnetic levitation, the BadgerLoop pod is nearly 15 feet long, weighing about 700 kilograms, composed of 6061 aluminum, wrapped by a carbon fiber shell. The pod uses an eddy current braking scheme to come to a stop at the end of its run. At design weekend, BadgerLoop demonstrated their novel Halbach wheel control system, which provides the pod with propulsion along with active stability. The robust stability system - along with pods other systems- is controlled by an intricate and lightning fast controller area network (CAN). 74.91.98.34 (talk) 08:13, 14 March 2016 (UTC)mg74.91.98.34 (talk) 08:13, 14 March 2016 (UTC)

References

Thanks for the prose 74.91.98.34 on the Badgerloop. But we can't put anything in WIkipedia without verifiable sources. See the email text again for some suggestions.

I think the article, in its current form of a bullet-list with the 30 teams, is best served by a really terse couple of lines of text (max.) that covers the basics of the pods, and maybe just a bit about the team. Is 70 kg empty mass? What suspension system? What propulsion system will you use in the trial runs? Etc. N2e (talk) 13:37, 14 March 2016 (UTC)

Indeed. That is a press release full of editorializing, not encyclopedic content. — Huntster (t @ c) 21:17, 14 March 2016 (UTC)

Team Hyperlynx

Our design has changed a little bit. We will still be using a wheel system, and aiming for 250mph though. Feel free to check out our press link on denverhyperlynx.com — Preceding unsigned comment added by 132.194.33.29 (talk) 17:10, 14 March 2016 (UTC)

Take a look at the article. That seems to be exactly what is already stated there, and sourced. N2e (talk) 17:31, 14 March 2016 (UTC)

Hypertube update: Rev 5 (18 Feb) has superseded Rev 4 (8 Jan)

The Hypertube test track specs have been slightly updated. New Rev 5, dated 18 Feb 2016, is now the only version that can be found at the link listed in the article where the Rev 4 version was formerly found. (In other words, I don't actually know of a valid link to get to the Rev 4 version any longer, even though the Rev 4 version was at the Badgerloop link URL when I downloaded it in early February).

Two things seems to be needed:

1. Is there any way to make, or retrieve, WayBack Machine archives of pdfs? If so, I don't know how, and it might be helpful if someone would do it so that both the Rev4 and Rev5 specs used to source this article are available long term.
2. The article will need some updates. Several changes with respect to the

• track length (now better specified and a bit shorter than a mile)
• lowest track pressure the teams can count on (now roughly an order of magnitude higher) and changes to expected pumpdown times
• subtrack aluminum material spec, and thickness changes
• concrete height spec added, with potential for change later explicitly called out in Rev 5
• longer length for the acceleration profile of the SpaceX pusher device (was 800 ft, now 1600 ft).
• there may be a few others, those were the ones I noticed right away.
• entirely new section added (about a page long) with "Pod safety guidelines"; really, requirements since there are over a dozen "Pods shall ..." statements.
• Human dummy specs provided for all pods but the micro-pods too small to fit a dummy.

If anyone wants to go through the new spec and update the article, and the sources for the new specs, have at it. Cheers. N2e (talk) 13:24, 15 March 2016 (UTC)

I cannot find a copy of v4.0 anywhere. However, an archived copy of v5.0 is at http://web.archive.org/web/20160316030623/https://badgerloop.com/documents/TubeSpecs.pdf. Remember how I showed you how to use the bookmarklet to create an archive at the Wayback Machine? That works for PDFs as well. — Huntster (t @ c) 03:12, 16 March 2016 (UTC)

Yeah, I recall, and have it in my bookmarks now. Thanks for that! I've made probably a dozen web-archive copies since that time, and added webarchiveurls to citations, so it's still a pretty small fraction of the total number of citations I write up, and add to articles.

As for version 4, I have a copy I downloaded from the Badgerloop site that is indicated in the citation on the date I added the citation. If anyone wants it, I'd be glad to email a copy of it to you. Just ask, and maybe send an email address you want to use to my Wikipedia email link. Cheers. N2e (talk) 04:13, 16 March 2016 (UTC)

NYU Hyperloop

NYU Hyperloop is a team of 23 New York University Tandon School of Engineering students, developing a Hyperloop pod specifically for freight transportation with a design focus on reliability, speed, and modularity. NYU Hyperloop's design, SLATE (Specialized Load Approach to Transportational Efficiency), weighs in at roughly 430 pounds utilizing a LMD breaking system, Air bearing levitation, and a hyper-fast FPGA allowing for rapid throughput and low latency. With a ride height of 1mm, SLATE is aiming to reach speeds of 200 mph. —Lysiuk3880 (talk) 22:17, 15 March 2016 (UTC)

References

Thanks for the input, Lysiuk3880. A few questions and one comment. 1) What is LMD braking? 2) Check on 430 lbs. mass; is that empty mass, or with payload? Which will you plan to mass out at on your test runs? 3) Do you have a target design velocity? 4)What is your propulsion system? Comment: if you take the time to format each of your citations in standard wiki-reference format using the "makeref" tool, and place them here on the Talk page in that way, it will make it much easier for the volunteer wiki editors who frequent this page to check them, and then develop the actual text-with-sources that would be added to the existing bullet list in the article on existing teams.

Update of photos is needed

Photos/images of competing pods

The Verge has published a June 2016 article that has photos or graphic render images of the majority of the pods that will be competing in the next couple of months. Here is that link: Here are the Hyperloop pods competing in Elon Musk's big race later this year, 18 June 2016. Suspect most of these images cannot be used on Wikipedia unless (and until ...) the teams release the same images with Creative Commons, wiki-acceptable licenses. Cheers. N2e (talk) 17:11, 20 June 2016 (UTC)

The most comprehensive set of photos—about a dozen—I've found is in the Business Insider article published on the first day of the pod competition. <ref name=bi20170127/> is the refname in the article, at this link: http://www.businessinsider.com/spacex-hyperloop-competitions-teams-2017-1/#openloop-northeastern-memorial-university-princeton-cornell-harvey-mudd-college-and-the-university-of-michigan-26

Student teams only for Comp 2?

Should this be mentioned? Someone did add rLoop to the Comp 2 list a week ago but unfortunately they're not competing due to this restriction. I believe they are exhibiting at Comp 2, though.

The official competition website alludes to this ("The competition will include new and returning student teams") but doesn't make this clear.

I don't remember where I saw this rule explicitly stated but I can dig for a source if need be. — Preceding unsigned comment added by Mathnerd3141 (talk • contribs) 17:11, 11 August 2017 (UTC)

The list of 25 teams listed on the SpaceX Hyperloop website (see next section, below) are all university teams. Cheers. N2e (talk) 06:43, 20 August 2017 (UTC)

Competition Weekend 2 is one week away

Competition Weekend 2 is next weekend; seems to start on the 25th of August.

The SpaceX Hyperloop website now has the teams posted. Looks like a lot of them: 25 approved as of April 2017. http://www.spacex.com/hyperloop

Looking for a list of which teams have actually come to to Hawthorne with a car that meets design safety specs and will race. N2e (talk) 06:42, 20 August 2017 (UTC)

MIT Hyperloop has dropped out of the competition

The MIT Hyperloop says they are out now. That's per this source: https://twitter.com/MITHyperloop MIT Hyperloop page on Twitter.

• "That journey, however, ends here (for now). We are currently not involved in any competitions or Hyperloop-related endeavors." — 23 Aug 2017

They've left a link to all of their documentation here. I'm guessing that will get mentioned in one of the reliable sources in the coming days, and we can improve the article then. Cheers. N2e (talk) 01:29, 26 August 2017 (UTC)

Links to http://www.spacex.com/hyperloop

http://www.spacex.com/hyperloop is good for finding out what has just happened and what is coming up but the information it has gets updated frequently. So what it said last year isn't what it says next year - which makes it a lousy reference for WP.  Stepho  talk  10:32, 23 June 2018 (UTC)

User:Stepho-wrs, yes, agreed. That can serve as a source for some claims in the article, especially if a full citation is provided and the editor indicates the date the source was accessed (or someone traces it back in the WayBack Machine); but as a primary source, it is definitely not the best source for improving the article, where secondary sources are preferred.

Moreover, there is almost nothing in the article now about the July 2018 competition, and too little with poor sourcing on the 2017 competition. (see next section below) N2e (talk) 18:37, 22 July 2018 (UTC)

Competition II (August 2017) section has a large amount of speculative information

The Competition II (August 2017) section has a large amount of speculative information, based on a source from four months prior to the August competition. Unless we can find better sources, I'll probably just delete the entire large table of speculative info; the part that begins after this statement:

The 24 selected teams planning to participate in the August 2017 competition as of April 2017 were:

Anyone have a better source on who actually competed in that competition? Cheers. N2e (talk) 18:31, 22 July 2018 (UTC)

Seeing no sources, I have removed the excessive detail in that table, and noted it in the edit summary. Cheers. N2e (talk) 07:58, 28 July 2018 (UTC)

Sources for Competition 3 (July 2018)

I just located the first secondary source for this years Hyperloop Pod Competition, the one going on in the US later today. I'll start to collect them here. Please add other good sources you find. Cheers. N2e (talk) 19:53, 22 July 2018 (UTC)
