Hello Bitcoin-Community,

Polivka GmbH presents the Mining-Container, okay for >100kW of your gear:

Outside



Right aisle and shelf



Left aisle



Filter from top



Filter from bottom



Air outlet from bottom



Silencer



6 Piece 32A-three phase plugs



C13 connection cables



Left fan



Power distribution box from inside



Power distribution box



Power distribution overview



Measured air quantities:

Fans in delta operation (fast mode), filters clean:

27200m3/h (16 009cfm), 70Pa pressure difference between inside and outside

Fans in delta operation (fast mode), filters "dirty" (covered):

25502m3/h (15 009cfm), 140Pa pressure difference between inside and outside

Fans in delta operation (fast mode), filters very "dirty" (covered):

21482m3/h (12 643cfm), 190Pa pressure difference between inside and outside

Fans in star operation (slow mode), filters clean:

21205m3/h (12 480cfm), 50Pa pressure difference between inside and outside

Fans in star operation (slow mode), filters "dirty" (covered):

15301m3/h (9 005cfm), 140Pa pressure difference between inside and outside

The fans suck in the air from the front through the filters and push them over the silencers outside again - the noise level is surprisingly low!

The container can be loaded and unloaded without crane using the pictured pillars and an air-suspended truck only. (Almost all of the trucks in Europe have air suspension)

Prices are all net, without taxes (for commercial customers or export):

Base Price:

EUR 8900
~US$ 10,200 at the time of writing

includes the adapted container, the fans installed but not wired, the filter and silencer

Fully flexible, adjustable shelf 3x 97cm wide, 60cm deep, ~2.3m high, 7 compartments
Roughly 3x38inch wide, 23 inch deep and 7.5 foot high

EUR 1600
~US$ 1,800

Electric installation (6 distributors with 32A 3-phase connection each, 114 C13 cables in total fused with 10A each, 6 three-fold "Schuko"-outlets fused with 16A, 2 motor protection switches for the fans, 2 lights with switch)
Pictures and price of electric plant is for 230V and European regulations.

EUR 3600
~US$ 4,100

Pillars zinc-plated  (4 piece)

EUR 1600
~US$ 1,800

  This would have been nice to have last year, but this year prices make it too costly.  100 kwatts  are about 140 s-5s  since you have 114 plugs lets say it will do 114 s-5s'   114 x 1.15 th = 131 th

At 8 cents a kwatt . that 18000 usd unit take 81 days to pay off. 

I have left the shipping price out.
I have left the psu price out.
I have left the s-5 price out.

I have frozen the diff at 42 and in 3 days it is going to 45

I have to say it is a nice piece of gear .
I would love to have filled with s-5's mining in a warehouse using some low cost power.
Good luck selling it.

I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

Costly compared to what? Ever asked for a quotation of a factory hall with all the cooling and power distribution? Also with this you are more flexible regarding the location.

I know mining calculations look not really good at the moment - guess why this thing is still empty...

To be perfectly honest on this: these guy's beat me to it: http://cryptokube.com - they came out when I already purchased the container, however I think my concept is more suited for mining and less like traditional shipping container data centers.

Well you killed them on price it seems.  It would just be too hard to recoup all the costs associated with this and the hardware during this time unfortunately.

Very well thought out piece of work though,  well done.

Tired of substandard power distribution in your ASIC setup???   Chris' Custom Cablez will get you sorted out right!  No job too hard so PM me for a quote

Think about bracing the supports along the length of the container. Two additional pieces of square pipe won't cost a lot more.
I don't want to be there when a little wind, like 6m/s (if placed outside) will literally put the mining box "on the ground".

http://www.yourspreadsheets.co.uk/wind-on-structures-analysis-to-ec-1.html

There is a free XLS there allowing you to do some wind calculations without printing or changing logos or something.
Good enough to see how big the bracing should be.

It will win if you can find cheap electricity.

Suggest this is perfect for farms with biogas generators waste heat from container can be cycled into digesters to help maintain higher digester ambient temperatures for spring fall and winter. Going "green" energy for this system would be viable. You could have a large number of smaller operators using this sort of system and pooling their resources.

This thread should be in Mining Hardware not Service Announcements.

There are actually two things still waiting to be delivered: Some guy cabling from the pillars to the corners of the container and a canvas under the container to prevent a short circuit from the air outlet to the intake.
As for the strength of the container itself: you can load >20to inside standing only on 4 corners.

Thanks. I already PM'ed ckolivas, who moved the thread - maybe he has mercy and reconsiders his decision. I guess a lot of interested people would miss it here.

As for the biogas generators: Don't they produce 2/3 of heat compared to electricity anyways? Do they need even more heat in the process?
My company runs mining in water power plants in Austria - if the numbers align a bit more favorably I will put it near one and fill it up with miners. Any project propositions - just PM me.

I'd definitely question the strength of the leg supports. What's the empty (no miners) weight of the fully-outfitted container? Adding 114x S5 to the mix will increase the weight by a good 900lb. Have you the engineering figures on the strength of the attachments, shear strength of the bolts and drilled-out tube?

Also, is there an option to run C20 cables instead of C14? If we're looking for space density, 2KW and 2.8KW PSUs (as well as SP30 and up) require C20 cables.

It's not that your price is costly compared to anything similar, it's just that the mining market is so saturated already that there is no hope for professional miners to succeed right now, unless 1) you live anywhere above the polar circle AND 2) have access to (preferably low-latency) internet AND 3) have access to hundreds of kW <$0.04 kWh AND last but not least, 4) have access to an investment capital >$100k.

OR, mum's garage and call "ROI" what would be like stealing from her wallet at night...

I have been mining for over a year at profit (GPUs then ASICs), even rented two dedicated room for this, found investors for the equipment and foolishly guaranteed their principal, now we have to cover for this from my own pocket and my associate's, just to recover our investors' principal (as we were not scammers, we didn't implement financial insulation like an LLC or something). It's so frustrating for many of us, really. But you know, lesson learned Wink

The pipe is 80x80x5mm. I had these made and dimensioned from a company licensed to do such things.
The thread on the bolts and nuts is M30.
The empty weight of a 20foot shipping container is 2.2tons. I didn't measure the weight of the fully outfitted container but I'm sure it's way below a ton without miners.

Any options for outfitting you wish. The cables are now C13, the female part which directly goes into the PSU. I have done this having SP20 in mind because of the better $/hash ratio and cheaply available second hand server PSU's.

Everyone mining needs something providing shelter from the elements, cooling and power distribution. I believe this to be a very elegant and flexible solution and mining will somehow eventually continue.

Nice work!  Great price!

Looks like a great product.

Can you just answer a couple of questions.

1.  How do you get air through the filters when this is sitting on the ground?
2.  How do you change the filters when it is sitting on the ground?
3.  If it stays on the stilts how do you enter the unit?  Cargo doors with ladder?
4.  If you open the cargo doors in a snow storm and go inside how do you close the doors to do your work without getting snow and weather blowing in?
5.  How do you keep condensation from forming and dripping on the machines?

I love to talk with you sometime and compare notes.  We could even maybe highlight your product on our page so EU customers have an option.

I wish you much success.

Thanks!

It's not meant to be run without the stilts, or anything else holding it up if you don't wish to purchase them (in case you don't intend moving it anyways).
You can buy a ladder from me - tailored to the container, however you probably want to solve that problem yourself because of the price...
It's possible to lean the door to the sealing from the inside.

I prevent condensation the same way you do - heating the inside by means of bitcoin miners  Smiley

This is simply amazing.
-GREAT- job!  Grin

I know this doesn't have much practical use with today's prices, but this concept is brilliant.

One question that I didn't see explained, why do you have the air vented out from the bottom of the container instead of the top?

Hi. Thanks for the flowers  Smiley

I didn't want to injure the outside skin. Also water-proof silencers are much more expensive.
It would be nice to suck in the air from the top, but also rain comes that way so I abandoned that idea  Wink

yeah you built a really nice piece of gear. It is too costly  because buying 114 s-5's or 114 sp20's don't put you ahead of the curve due to the terrible price of BTC.

If I could get this miner

https://bitcointalk.org/index.php?topic=944406.0

It would work.  this miner does not exist .  putting 114 s-5's or sp20 in  that crate  won't pay off.

Now if I had cheap power yeah maybe.  

I do like the build.

In colder climates an issue is often to maintain heat in the digestor tanks and they often have to be buried and insulated as you may know heat loss can lower gas production.

http://acep.uaf.edu/media/50756/ACEP_ResourceOverview_Biogas.pdf

Quote
Thermophilic — Between 49˚–57°C (120°–134°F)
Mesophilic — Between 20˚–45°C (68˚–113°F)
Psychrophilic — At or below 20°C (≤68°F)

Quote
Conversion of biomass to biogas is greatly accelerated at
warm temperatures, falls off sharply at low temperatures
and is almost nominal below 15°C (59°F). Most
commercial and industrial biogas facilities in operation
today maintain a stable temperature conducive to the
specific microbial community that they utilize. Often
this involves additional heat inputs to maintain high
microbial metabolic rates and system performance.
