Hello everybody.

I was imagining a car or a bus, with an invertor from 12V to 220V, inside the back of the car, with a miner, with a wireless router/bridge  with a cell phone next to it sharing it's internet connection to the miner.

The car should not be an %100 electrical car. A car burning a fuel is OK.

The longer the kms or miles the vehicle takes the longer the miner works.

Solo, PPS or PPLNS.

I think SOLO or PPS is OK but not PPLNS.

What do you guys think, if it worths or not building a project like this ?

You pay no electricity, right ?

Okay to make the inverter work it runs off the alternator.  So if you stress an alternator you get worse gas mileage.

My guess is if you run a few sidehack compac usb sticks off a rasp pi and solo mine them it could be fun.
But trying to  run a big miner would not be  easy.

why an inverter? Almost every miner known to God runs on 12 volts. Just bus that straight to the battery (use a 12 volt 30amps contactor tied to key_12 volts if you want it off when car is off) and go to town.

You get free gas?

Also check the output of your alternator. Most cars are below 100A.

Sounds pointless to me, you would only be running the miner a few hours a day all the while difficulty is ramping up.

well it would have to be well built...i mean all the vibration and the bumps, etc.  Plus you would need an extra battery or something, I suppose it would keep the alternator on too much.

It works on very small scale like a few usb sticks in a taxi cab.

great idea this in a future world. Imagine a car that create some satoshi's with the km it done and then it can pay the electricity charger or fuel supply with them.

 You pay in gas usage for the electric usage of any miner you installed this way - which is VERY inefficient overall.
 Probably a complete waste of money, unless you're doing it for bragging rights or some such.

the car create electricity from the movement. It can spent a part of it to mining.

Thank you for all the answers.

I'm an IT guy but not an electronics tech or engineer. So as I understand, an antminer S3 is also a load for the alternator. I know S3 uses 300 Watts something, but I have no idea about the amperage.

Anyway, as I understand from all your answers, I guess, an Antminer U3 like miner with a new 16nm chip or chips will be more than enough.

Hımmm, also it should not be usb connected one. Should support wireless.

Evreka...

May be ANTROUTERS do this with some new versions.

But I understand, inverter is not needed, and alternator should not be loaded.

...

So you are saying that. The car's kinetic energy turn to electricity and mine in the back. But in your country is mobile network works almost anywhere?

However ,the  inverter doesn't run by itself.You need to charge it with massive amounts of electricity which is equal to the charge costs while running the miner at home.Also,does your government allow you to carry such hardware in your car? You again need to keep the AC on all the time miner is running in the car which adds to extra expenses.

Yes, there are 3 huge mobile networks, all cover more than %96 of the country. Turkcell, Vodafone and Avea. Especially in big cities , it's no problem, I'm planning to put miners on TAXI cars.

EDIT : Well it's a dream only. I'm an IT guy, I cannot handle people... :)

What about the heating problem? How are you planning to cool the miner ?
I think you need extra cooler for this.

Hıımmm. For Winter is OK. But for summer an additional piping/ventilation is required. If the car is moving a pipe can feed the miner with the blowing air.
This needs a whole new design and depends the brand model of the car. Somebody will do it in the new future.
I may do it as an amateur way.
But the problem is I do not have a car.
It was just an idea. This thread may start somebody with sources (knowledge, iq  and abilities) to start the task.

Its not a bad idea but not really worth it. You can buy a 1300Watt power inverter and use cellular data but those alone will cost you more then you will ever make.

Especially considering people drive for only 1 hour a day.

A car does not simply generate electricity by moving, that energy comes out of your gasoline.

Gas turns the engine and the engine turns a belt that turns the alternator. The extra energy your alternator will have to take from the engine to power the miner directly burns more gasoline a a result.

The alternator is controlled by the voltage regulator, it pretty much tells the alternator how hard to work depending on the power needs at the time. In normal operation the car doesn't require that much electrical energy to operate so the alternator doesn't work as hard as it can, putting only the minimum draw on the engines power. Increasing the draw by adding accesories, such as a miner, increases the load on the alternator and the strain on your engine.

I'm pretty sure that your car is not going to be able to efficiently enough convert gasoline into electricity $/KwH to compete with an electric company so it will just cost you more. Instead of paying for your miner's energy on your electric bill you will be paying more for the same thing at the pump when you fuel your car.

Small scale in a taxi cab could work.

Twenty watts or less for all the gear.  Once you go to big scale 300 watts even 200 watts not much chance since the power will cause far too much load on the alternator.

Since a taxi idles and sits at lights a lot a small setup may not really hurt the gas mileage.

 Car voltage varies a fair bit - and tends to be closer to 14v DC not 12VDC when the battery is charging.

 Some miners might be able to handle that, some might not.


 There ARE ATX-type power supplies built for a 12VDC input, dunno if any are Gold or better efficiency.

he does not need an inverter he could use a voltage regulator

50 watts at 12 volts 120mv ripple

I think this sumarises it. car engines are far less efficient compared to power plants in terms of conversion of fossil fuels to electricity, you'll probably get cheaper electricity directly from the grid. the only aspect where I see this making sense is from waste energy, heat from the engine for example or maybe vibration? or heating/kinetic energy from brakes. Recovery systems in hybrid cars use kinetic energy from stopping to recharge batteries. there are thermocouples that generate potential difference from heat, are u referring to these instead?

Unless you're going to mod the pulleys and accessories you're not going to get much juice to run a miner - especially something that can handle the vibration abuse. It may be fun for tweaking but not a fruitful endeavor.

Since the main factor deciding whether a miner can be operated economically is the energy cost, you need to look at that:
How expensive is one kWh of electrical energy generated in a car compared to the same amount of energy if you bought it from your power company?
I'm not going to calculate it exactly, it's sufficient to realize that if electrical energy from a motor-driven generator were cheaper than utility-generated power, everybody would be using motor generators. Apparently people don't do that, which tells me that it's not cost-effective.
q.e.d.

Brilliant idea m8, I wonder how nobody had thought about this before.  ::) Mobile mining is literally the future.

I saw this as a bit crazy, could be because in europe fuel is too more expensive than on usa. I'm sure that with european fuel costs this isn't a good idea cost/effectivity isn't a good deal. And i see a problem with the car moving, its easy to loose the connection.

I have a 220amp alternator and a built in hotspot. I'm gonna wire up a s3+. Drive about 4-5hrs a day so it should be worth while. Plus it will heat my car

The Volvo is ready, lets go!

Your idea is great mate! It doesn't matter you don't have a car or you don't have enough resources to make it work, what matters is the idea. I think in the future something similar to it will be used a lot. I mean the electricity and the ventilation provided from moving. That's really great idea.

This miner in a bus idea is completely stupid and totally impractical.  Now if you could set up your miners somewhere and get free power without anyone knowing, now that would be a good idea.

This already exist in little different way, with ads displayed on the car. By the way, the same concept but paid with bitcoins could be a good idea when it will be more adopted.

To focus on OP, I don't see any particular interest to this, since you use gas to fuel your car. If driving is your job, like if you're a taxi driver or if you're a truck driver, maybe it could be interesting. But profit won't be that much, and with all the costy installation this would bring this won't be a good idea.

Very intersting don't think I've seen a trunk quite so full of miners.  Is there a story behind? Big buy?

Anyways thanks for sharing pic!

Has anyone tried this yet?
If yes, how long did it take you to make 1 BTC (if you have)

Its not a practical idea and doubt it would ever work.

lol at that picture, what a mess, the space is too narrow, the heat will not be easily released, bad airflow....

at best you can try with something small, that do not need a big psu

How is it so far?
Isnt the electricity just from the engine. Won't you just end up burning more gas?

That is not OP who talked about mining in a car.  That is a trunk of miner's most likely being moved to somewhere to mine.  But they are not running in trunk off car.

So neat picture but it is not a mining area in that car.

The op said it would be in Taxi cabs it would work fine on a small scale.

Assuming you are paying for the fuel, the bottom line here is what does it cost to generate 1KWh in a car and how does that compare with your local Power cost? I have no data but my bet would be that it is several times more expensive in the car?

A bit of data from the net for a Diesel Generator shows 20KW generator at 1.6 Gals / Hour at full load.

So if we take a Gallon of Diesel at $2 x 1.6 = $3.2 for 20KWh

Off the grid at 10c / KWh = $2 for 20KWh

This is of course for a generator, car could be better or worse? However it's much closer than I expected, so perhaps I have got the data or the maths wrong?  :)

Diesel I think you have too low.  I don't even think you can get offroad diesel for that price.  That is first part I would check.

Other thing is cooling how are you going to cool it? Say it's in trunk it might be insulated enough to block noise, but it's going to get hot.  And it's pretty hard to do a temporary mod for cooling that is realistic on a car.  So I think it still has some problems in idea.

Maybe a truck with a freezer might work for this project :)

Something like this:

op has stated it is in  a taxi cab.


 and on a small scale it will work.  at least in my opinion.

Do you think heat would not be a problem?  I would guess miner would be in trunk on taxi.  It just seems like the trunk would fill with heat, and no where to go.

During summer I see even bigger issue winter might possibly cool it from cold outside.  So I guess it could depend on season to.

Ran 2 of my paperweight X-1.5 on a road trip on slushes pool and made a whopping $1.32 not bad on a 8 hr drive. On the way back I made $1.92. gas is $1.70 here so it was worth it. Still got 20mpg in my 2015 Dodge Durango R/T


This was using the in car power outlets. There two rated at 200w ea. Put off very little heat which I could have used as it was cold out.

i know that mechanical thing like fan and something else, don't last long if they are on somethign tha move all the time

so i don't see how this is a good idea, unless you plan to sit your car/truck all day in the same location
