`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

`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.

`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

`
`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?

`
`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.

`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.

`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

`
`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

`
`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.

`
`I think is a nice concept.
`
`In my opinion needs to improve the airflow a cold area with positive pressure and a hot area with negative
`pressure and density unless is able to handle 400 KW is not very efficient. I am totally sure can fit more miners

`There are actually two things still waiting to be delivered: Some guy cabling from the pillars to the corners of the container and a

`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

`
`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.
`
`
`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.

`We put a lot of time and thinking into the inner layout and airflow design of this. Main problem is that the
`container will probably live trough more than one miner generation - so it is impossible to tell how exactly they
`will look like.
`If I know that I'll fill this thing up with SP35's only I would have done a different layout. But given the premium
`for Spondoolies rack hardware and the quality of BITMAIN 19 inch miners I wanted to stay flexible.
`400kW air-cooled on 3m of shelving is a little optimistic.... however, with SP35 maybe possible, didn't run the
`numbers.

`
`Hi. Thanks also.
`I know investing in mining does look horrible at the moment, even with cheap power and all that.
`You can't write off the container in 3 month, like you might still be used to calculate when evaluating a mining
`invest. Most home miners already have a power outlet and don't need to build anything to get rid of the heat
`from one miner.
`On a bigger scale this also causes costs, and not to little of it. You can't avoid it if you want to have cheap power
`- it doesn't come to you, you must move to it.
`Therefore a mobile solution is a nice thing to have. You find a place with even much cheaper power? Not an
`issue, truck comes tomorrow.

`
`I guess this is for gas production only - as soon as you use the gas in a combustion engine to produce electricity
`you should have heat in abundance.
`In Austria some of the biogas electricity plants also offer the service of drying wood chips with the excess heat -
`I'm not an expert on the biogas field, but we have been thinking on offering the wood-chip drying with miner
`heat for a second...
