Alternative Electricity for Mining

[gsrcrxsi314]

Soon there will be even more farms that are in optimal climatic conditions, for example, where you can use snow cooling or electricity from renewable sources, such as the sun or wind.

What do you mean “soon”? Farms have been doing this for years. Moving to areas with favorable climates (like Genesis mining in Iceland) and electricity rates. It’s not anything new.

How about pumping water up and the placing several turbines downstream?
Lets say several = infinite.

[Metroid]

Btw, obvious improvement is missing - u input 500W and get 2kw, why not short-curcuit the whole thing?
Feed the motor not from the grid but from the output.
This way u will still get 1.5kW output and no need for the grid AC!

A 50cm exhaust fan will give 1.5 mph and that is not enough, wind turbine won't work with that, 3 x 1.5 = 4.5 mph might do but you will get very little to bother about. 7 mph or 3 m/s is really the minimum.

The research and knowledge being shared about this alternative source of power for mining is great but this method would be definitely be suitable for only small mining rigs and not those huge mining farms way back in China.
Great job with the research though!

[Thermytee]

As simple as this posts is, it doesn't take into consideration the big and heavy miners. This looks to me for those mining on a small scale and would like to have a stable electricity. For big miners in China, this doesn't suffice for them as their power setup is enough to break up the bank. Nice posts.

Alternative electricity for mining is very necessary, given the high cost of electricity in some regions of the planet. Solar panels, wind generators, hydro generators, etc. — everything can be adapted for efficient mining. However, the advantage will be on the side of large mining farms, as they can buy this equipment in bulk at discounted prices. Perhaps, small miners should purchase equipment together with other miners to save money, and then earn more on mining cryptocurrency.

Unfortunately, at the moment, alternative sources of electricity still have an insignificant part of the total electricity in the world. This adversely affects the ecology, and the cost of electricity and, accordingly, the cost of mining.

Remember that, if wind , solar or any other renewable source, if grid tied, electricity provider will never pay or give you what you gave them and most places you pay taxes for that, I know is bullshit but that is how governments are ran by crooked people all around it. If off grid then your kwh in your home country must be greater than $0.50 to be worth, Germany perhaps? Anybody saying that using batteries for mining is worth is lying blatant. Just to clarify regarding batteries, you will need around 48 x 12v 200ah(60 kilos each battery) to run a mining computer of 1800 watts per 14 hours, the other 11 hours must be ran using the sun power generated electricity, the sun needs to be on its best case scenario,  most good places around the world gives 6 hours per day full power on your solar panel. So is pointless because in truth to run 24/7 without problems you will need 17 hours of batteries and the sum of 48 is just for 11 hours, 3 hours more means 12 more batteries, using 4 interconnected on 48v.

https://www.amazon.com/d/Motorcycle-Batteries/12v-200ah-Solar-Power-Battery/B00RPOI7F4

Each battery will cost you $350. 48 +12 = 60 x $350 = $21.000 only in batteries for just 1 computer using 1800 watts per hour and that battery will not last much if you dont use it properly, the calculation is based on 30% usage of the full battery power.

    Starting battery (Automotive battery etc) : 3-13 months
    Marine Battery : 1-6 years
    AGM Deep cycle: 4-7 years
    Gel Cell Deep Cycle: 2-5 years
    Flooded Lead Acid Deep Cycle Battery (L16-RE etc): 4-8 years

The calculation above is based on properly used batteries, most batteries cant be used more than 30% of its full capacity. Want to use 99% of its usage, get better cycle? Then get the tesla batteries made by lition.

https://www.tesla.com/powerwall

13.5 kwh but pay attention you can use only 5kwh continuous but if is only for one to 2 mining computers of each 1800watts should be okay. It's a huge investment which might never pay off even if bitcoin is pumped to 100k usd.

Also remember that solar panels have to be triple of what you want, cause 33% is to run the computers and 66% is to recharge the batteries for the night. For example if each panel is 300watts then 6 x 300 = 1800 watts that is 33%, then you need to buy more 12 panels. Total of 18 panels just to run a pc of 1800watts.

So all in all, off grid mining is a fail, on grid is a success but only if your government treats you fairly well which most dont.

So you’re sticking a mini AC unit in front of a miner at +20% the electricity cost. Wow. Such amaze. I wonder why all the big mining farms don’t do this?

Absolutely this man is doing really amazing job and others miners should follow him to get more lowest cost of electricity for mining.

[Metroid]

The inverter is 15kw-60kw output which is enough to run many miners.
(This same amount of electric on a home line would cost you hundreds of dollars per month)

The generator head produces 2000 watts of 24vdc then uses the inverter to convert the 24vdc@2000 watts back into battery bank to help you get up to 15-60kw 115/220vac useable power. Batteries and charging may vary. The more power used more batteries and charging power needed. You can add more generator heads and batteries easily or a larger motor if needed.

This setup will produce a max of 60000 watts of AC electricity rated @55 amps of 110/220vac.

I use 24v batteries but the diagram is setup to use 12v to create your 24v battery bank.

USE CAUTION WHEN CONNECTING THE BATTERIES
MAKE SURE BATTERIES HAVE GOOD VENTILATION

Looking back, I did not want to say anything at that time, it has been some time, somethings he got it right, some wrong. I really wanted the guy to show some proof but I guess nothing yet. In theory if the turbine is not at more than maximum capacity there is no way this will work.

First, negative aspect, there is no need for an inverter of 15kwh to 60kwh since that motor will never output anything close to 3kwh cause the manufactures fully states maximum it can generate is 2.8kwh if turbine is 130%, it must be a super ultra wind to do that.

Second, positive, 8 x 12v 100ah will only give 1200 each battery, 8 x 1200 = 9600*30/100 = 2.8kwh, if the turbine works 24/7 130% which is unlikely depending how he did.

Third, it does not matter what kind voltage you use, the outcome will be the same, I would use 48v on the batteries, 4 x 12v, slim cables.

All in all, this will only work if he can get the turbine to work 130% 24/7. Still waiting for proof.

I can’t tell if you’re trolling or just stupid.

His plan doesn’t work. You can’t get more energy out than you’re putting in, which is exactly what he claimed.

It doesn’t work. And won’t work. That’s why he hasn’t come back when he got his first electric bill and it wasn’t lower.

You can’t get more energy out than you’re putting in.

As it stands that is very true, however concerning everything, only the 24vdc 2000 watt Model PMG Generator $499.00 at 130% was a hoax in his statement. It doesn't add up. There is no point adding a 3kwh exhaust fan to blow air and get 3khw. Now if you have that 3kwh exhaust fan somewhere, adding the windmill fan turbine will give you some power back, in this case at least 1.5kwh but this is for another topic as this is getting something from wasted energy.

3000 dollars is quite on the high side. Anything within 500 - 1000 dollars will be fine with me. If I have an energy supply of over 60k Watts, I will most likely supply it else where for the cash considering the size of my mining implements.

you'll always get back less power than your putting in. so you're just wasting energy and money. that 3000w fan is costing you money and you're collecting less than 3000w from the windmill on the other end.

cheaper to just plug the miner straight to the wall. you can't win against physics.

the only "free" energy is solar/wind. but they aren't constant, and will cost a considerable amount of money in the infrastructure upgrades to be able to capture/store. on a very long time span (>10 years) it'll even out and start to be worth it, but mining cycles don't last that long.

[adaseb]

No idea if this was mentioned before or not. But with regular cars there is obviously an alternator. This alternator always spins, depending on how much current is needed sometimes there is a load placed so the engine needs to adjust to apply power to be able to spin the alternator.

However when the car is fully warmed up, and the battery is fully charged, then there is a small load on the alternator but this electricity pretty much is wasted, since there is no clutch in the alternator like a AC compressor.

So you can probably power a GPU or 2 with no additional cost in gasoline. No idea if someone tested out this theory before. You can't run an entire rig as you will pull too much current and the alternator will need a higher load which will cause the engine to use more gas.

If your theory gets a continuation, then along with electric-cars we will see mining-cars on our roads. It would be cool - you go and earn!

[Coffeehot]

in my opinion, it is not feasible. it will consume more power during the conversion process. i think the best saving strategies are solar and wind energy.

Come on mate, the other one is disputing the OP's point. Better read the thread before jumping in.

It was an interesting discussion (except the trollings on both sides) and I agree with some that this set up best works for smaller miners (atleast for now).

[Marvell2]

Grid tie solar is the only way, you still want to overspec say 50 percent so you have excess power to sell back to utility which offsets your nightly use
