Hello everybody

I make a model to reduce a energy consuption for mining farms.
The basic idea is to use gaspistons gensets with cogeneration\trigeneration systems.
With this idia we can get chep kWe and free thermal power wich we can use to produce colling way in trigeneration system.

so, could you beso kind to share some datas of energy consuption for 1 bitcoin?
(industrial mining farms)

i need:
- electricity consuption for main equipment   kWe*h
- heat release for 1 bitcoin
- electricity consuption for cooling systems,

or just  give me some links to reed 

thanksalot!









 

That would be about a year of mining at home so that is probably equal to your electricity bill for that time.  :D

thanks a lot, but i'm talking about industrial volume, where electrical consuptions is lower than in home mining

ok.. remember that numbers vary because bitcoin is more luck and difficulty chasing rather than something linear/stable

but here goes

antpool in the last 48 hours has averaged 3 blocks an hour (75bitcoin)
with an rough hash rate of 350 PH/s

now..

that 350PHash is the equivalent to 74000 mining rigs of 4.73ghash running at 1.3KwatH each

knowing the specifications can vary by 10%.. lets make it into easy maths

75btc per hour for 75000 rigs
1btc an hour for 1000 rigs

1btc =1.300megawat hours

1.3 million kwh means 50k dollars per btc in electricity.

franky1, i guess I had a misunderstanding with the dimension.... (((

1 bitcoin costs ~~ 456 usd
1 kWe*h  costs ~~0,4 usd

for 1 bitcoin we need ~~ 130 kWe*h

am i right?

 ???

one antminer s7 generate 0.37 btc per month  and consume 864 kwh per month

you need 2.7 antminer for 1 btc per month, which would consume 2332.8 kwh per day

so, one antminer s7 generate 0.37 btc per day = 11,1 btc per month
which would consume 864 kwh

846/11,1=76,21 kwh per 1 btc
but with franky's data we get 120kwh per 1 btc  ??? ??? ???

wtf thats sounds super cheap
isn't like 10-20 cents per kwh?
so 120kwh = 1BTC = 12$
lol no way

I look forward to this threads conclusion...

seems people cant read

1 rig is 1300 watt
which is 1.3kwatt

so 1000 rigs is 1.3Mwat

1 bitcoin is 1.3Mwat or 1300kwat

so if it costs 5cents per kwatt

thats 6500 cents or $325

yep china pools such as antpool that has zero equipment cost (because for every 1 retail sold unit they are able to produce 4 units with the profits) can make a bitcoin for $325

but in the western world at 20cent a kwat and $1000 a unit ($1million hardware cost for 1000 units)
with 6 month life span that is a breakdown of $248 hardware cost per hour

and $1300 electricity cost per hour.. so costing $1548 per bitcoin in the western world

bad typo, i mean 0.37 per month not per day and smaller not greater

wait there are some errors

ok you need 80 antminer s7 to mine 1 btc in one day, this is 1200w per 80 x 24 = 2304 kwh per day to mine 1 btc

What is the prediction that s9 will produce in this same time frame compare to the s7?

How does this even work?

To reduce mining costs you could use the heat generated to heat water and deliver this heat to houses in winter, but then coal/gas might be still cheaper and winter is only small part of the year + at the places where indstrial miners have cheap electricity (probably around 2 cents/1kwh) there wont be big town near anyway

The calculation for cost per bitcoin is actually very simple. The theoretical revenue (in bitcoins) per block is


where R is the block reward, H is the miner's hash rate, and D is the difficulty.


First, we calculate the energy expended per bitcoin. You can derive the theoretical hashes per bitcoin:


So, energy per bitcoin is:


where e is joules/hash.

If you are using an S7 (0.25 J/GH), then your energy/bitcoin today is:

(0.25/1000000000) * 194254820283 / 25 / 65535 * 2⁴⁸ = 8.34 GJ per bitcoin

The cost per bitcoin is simply that times the cost per joule. Assuming $0.10 per kWh, your cost per bitcoin today is:

(0.10/1000/3600) * 8.3 * 1000000000 = $231.76 per bitcoin

Well i think solar panels actually save quite a lot of energy if you're run a couple of miners at your home. Though they are expensive; its worth it in the long term.
