not at all, I myself am a Civil Engineer. also this is a student competition but you can apply as a graduate at this stage
you can find the required fields in the OP >>7688221

>>7689860
If you could at least stick around to provide guidance with the linear accelerators that would be awesome. We'll bear the grunt of the work anyway. Just shoot an email, I promise I won't tire you :)

We have a Twitter account although it's University oriented (in accordance with the competition) and 4chan isn't mentioned although you can clearly see Sci there

I'm glad you asked anon!

>1. What is this
Hyperloop is a concept brought forward by Elon Musk, co-founder of PayPal and Tesla Motors and founder of SpaceX. It's basically a train going inside an evacuated tube (near zero pressure but not vacuum). The planned operational speed is around 1 Mach and the Hyperloop Pod (the train) is thought as an efficient transport method over long distances around 350 miles / 500 kms
What we are doing is designing that pod, since SpaceX has announced a competition back in the Summet 2015. The team we've assembled from /sci/, although got depleted and had to be reinforced with non-sci members, have managed to make it to the Design Weekend - finals of the design stage basically. We're going to present our final designs there, and if accepted, we'll build the pod.
>2. How can I help beat leddit
At this stage, by joining the team. For that you can check if you can provide the required help as written in >>7688221.
If not, no worries, we're now starting to build a nice website and making ourselves visible on the social media. Publicity is the bread and butter of Leddit's team, they are all media and we'll need to outdo them in the publicity as we're nearing the Design Weekend. Stay tuned

Staging Area Network Access
An Ethernet 15 port switch will be present at both the ingress and egress staging areas. These two network switches will be the only network access points to the Pod. Teams may determine how to allocate these ports. Pod Network Access A 12” x 8” x 1.5” (WxHxD) Network Access Panel (NAP) will be provided to teams in the staging area with all necessary network bridge equipment. Teams are to mount the NAP perpendicular to the track surface with the panel facing to the rear of the Pod. There should be no metallic obstructions above or to the rear of where this panel is mounted on the vehicle. Teams should provide 6-32 mounting holes in locations shown on the network access panel drawing. A 0.25-inch clearance is expected below the NAP. The NAP will weigh approximately 3 pounds. The panel will have a DB9 Male bulkhead connector for power. The Pod should provide a 9-36VDC source to the panel. The pinout is provided on the network access panel drawing. The panel will also have a RJ45 Ethernet socket teams are expected to plug their Pod network into

>>7688261

Network access to the Pod is expected to remain continuous while the vehicle is in the staging area or in the tube. In the event of the loss of network connectivity, the Pod should enter a safe state.  Team equipment will only be allowed on this network when they are the primary team on the track. This is intended to prevent interference between teams.  Teams using their own communication systems outside of the tube shall not overlap with 802.11g Channel 11 (2462MHz). IP Addressing Teams are allocated a static 8 bit subnet 192.168.1.0/24. Teams may allocate IP addresses in this subnet as they like. There will be no DHCP or DNS servers on this network. There will be no external network access on this network. Teams shall not bridge this network or provide remote access to this network.

To quote:
>We want to ensure that teams don’t become ineligible to launch due to a real-time communications issue and that teams don’t devote disproportionately high effort to their communications system. Thus, we are looking to greatly simplify the system by:
>1. Reducing the number of Access Points from four to one (avoids having to switch AP’s during flight)
>2. Providing SpaceX-tested communications hardware for the Pods. We will provide a Network Access Panel (NAP) for your Pod, which will include the necessary antennas (see page 2 of attachment for top-level schematic). The NAP will have been well tested in the tube before the competition and configured to work on the provided network. The interface to the NAP will be a DB9 connector (power) and an RJ45 connector (data). It is not required to use the NAP, but it is highly recommended.

Communications
Connectivity to the Pod will occur via an Ethernet network bridged between the Staging Area and the Pod itself. SpaceX will provide all infrastructure for this bridge network. Teams will interface with this infrastructure from the Staging Area and directly on their Pod.  Bandwidth to the Pod will vary but expected bandwidth requirements should not exceed 20Mbps.  Network latency between the Pod and staging area is expected to remain <10ms.  or in the tube.

>Who's building it? is there a fab shop taking care of this, is it being built on a university campus, etc?
Currently we're in talks with GE to use their former 'Garage' area in my university, and that's the most likely. However we'll explore options building near Hawthorne, CA if opportunity arises once we're there.

>Where's the money coming from to build it?
SpaceX is awarding sponsorship to successful teams in the Design Weekend through third parties, pic related. However we are exploring our own sponsorship options, via University funds, foundations, VCs (we're accepted to an incubator)
>>7688550
wise
>>7688606
SpaceX wants the team lead to present personally so that's not possible. But if you'd stop by for a meetup that'd be great
>>7688613
Thanks bro

>>7688487
>time commitment?
Depends on you, but you'll probably be helping on the side. We don't expect anyone to commit full time obviously
>link to details about the competition

>when do things need to be wrapped up
Around 1/1/16 because we'll start documentation from that point until 1/13 which is the Final Package submission deadline
>what thermo and/or mat sci do you need?
Currently we have Process Flow Diagrams as given here >>7688342
Material Sci requirements are listed here >>7688358
I'm a Civil Eng so for more detailed discussion I'll have to refer you to members working on these

>>7688476
We'll have to do with what we have m80. Send an email pls

Have a grazing chassis

>>7688466
Ayyy
I was wondering about you, where have you been!

>>7688416
We have a ChemEng member who's doing thermodynamics work, perhaps you could help him?
Also as >>7688427 said mat sci help is sorely needed. The track on the ground and the guidance rail is indeed aluminum
>>7688422
Thanks bro

It's near vacuum, the white paper has the internal pressure at 100 Pa, but SpaceX allows a range of 0.02 Psi to 14.7 Psi(1 atm) for the competitors. We've chosen 2 psi which will be compressed up to 60 psi for air bearings, and 1 atm for ventilation

Hey JC what's up!

Well the usual stuff - mostly related to weight, material strength and cost. We have a carriage+chassis structure, so the materials will vary accordingly.

Another important subject is ease of manufacturing - will be critical in the building phase. We will have about 6 months to finish it, less if you consider tests and even less if we'll build it outside of US

We're looking at Maglevs for materials currently, but any other idea is also welcome

you've got it

>>7688274
the deadline is 1/13/16, so you'll get acclimated to the work at hand until 12/15 and start delivering after your finals. how does that sound?

We have our Comp Sci member working on communications, would you be interested in that?
