This is an awesome thread dude, keep it up!

Our 167kVA Transformer was installed today..

One of our clients has 6 shipping containers buried in his yard all growing weed. You can do some really fancy shit with these containers. Amazes me what a lot of my clients do for a living.

It was a slow day today,,  my foot was hurting so bad from gout I could not stand for a long time.  Logan and Burkin did a lot of work on the ventilation today.

We got the Electrical Disconnects hung and we open the Exhaust Hood for the first time today.

The ventilation system is going to move about 40,000CFM  That is going to exchange 100% of the air in the container every 2 seconds!
Do you honestly think it needs more?


In all my years of doing Electrical Construction and HVAC one thing I have learned is you never cut a hole in the roof of a data center!

I think you should setup more high speed fans. Do you plan to make any ventilation on top of container?

We got the Meter Base Panels hung today and got the hinges welded to the exhaust opening..

Hit me up, I sent you a PM. Our next one I am going to do VFD fans, We are rushing this one so we can get the mine online in one location.

Okay had a bit much to drink last night... anyways yes have Entergy in 2 co-locations and 1 on Demco. Have 4th co-lo being worked on now with 1600A 3phase build out coming. Not sure if you have looked at filtering intake air yet or not but have found using electrostatic filters to be the way to do it. Also just got the 3 phase 60in exhaust fan in that pushes 20k cfm and is VFD controlled so should be fun to learn to program since it is SCADA type of system. Also the reason the burn happened because the electrician that ran the 200A to the house 10+ years ago had it where the legs were touching so it melted the plastic eventually and shorted out one side... Here have a look.

Variety. I'd like talk with you but not here

Well hello neighbor,

Luckily I am a licensed electrician so its no issue when something burns. I tell you this we have pushed limits I have never come close to with any other industrial or commercial loads before.  I have ran 15 MegaWatts of generators before but never had a 100% continuous load on any thing.

Are you on Entergy over there?

In Assumption huh... I'm in Ascension! I thought I was the only crazy coonass mining in Louisiana. I had a meter go hazy myself and it shorted one leg out when some bad weather came through... hole straight through the meter head.

@seanreit & @CryptoSouth -  Looking forward to updates on the builds.  You're "Gods among Men" thanks!

I did not include partial as i did not feel like going that far into it..   Normally when I build a solar array we use 3x factor on a 5 hour day so we can insure we have enough to keep the batteries charged even when we have a few days of rain.. 

I build solar array's for the oil field to run PLC systems.  Even if you factor in 10 hours a day you cut the 7 years down to 3.5 the money would be better spent putting more hash power online as I don't know of any miner that is going to make a profit for 3.5 years..

Even if I were on a POCO like Entergy who is historically one of the most expensive I would not want to do solar, I would relocate the mine to a cheaper POCO..

@cryptoSouth

Did you include the hours of usable daylight where panels may not provide 100% of energy but some % less that offsets the cost?

5 hours per day providing 100% plus 5-6 more hours of offset may change your calculation for payoff to much sooner.

7 years for payback on a 400 panel install isnt half bad if you knew you would mine the entire time.

Solar is not a option for us, Lets do some math to show why.

We currently have 100 miners that pull 110,000 watts. The average good solar panel puts out some where from 250 to 300 watts so lets use 275.

110,000 / 275 = 400

So we need 400 solar panels to power the mine..  Now I live in South Louisiana and we get a fair amount of sun. But the usable amount we get that we would be able to run the mine at 100% is only about 5 hours per day. The average good solar panel is about 200 each wholesale.

400 * 200 = 80,000

I would have to buy $80,000 in solar panels alone just to power the mine 5 hours per day. Then I would need a grid tie inverter and a 100kw GTI is about 30k. So all in all I am looking at $110,000 to run the mine 5 hours per day.. 

I currently use about 78,000kWh per 28 day month so

"78000 / 28" / 24 =  116 kWh per hour

I pay approx .075  per kWh after fuel adjustment so

".075 * 116" * 5 = 43.5

So I pay $43.5 to run the mine for 5 hours in a day that means the solar system would save me $43.5 each day therefore ROI on the solar system would be

"110,000 / 43.5" / 365 = 6.92

I would have to run the miners for 7 years to reach ROI on the solar panels..   


Conclusion $110,000 spent on miners would be money better spent as it would make about 1 BTC per month right now and the ROI would be less than 10 months..   



Just my .02

Get on the solar on top of the containers and this will be clean clean revenues.
