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.

 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.

I'm no longer legendary just in my own mind!

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


https://www.trcelectronics.com/ecomm/pdf/sd50.pdf


50 watts at 12 volts 120mv ripple

I mine alt coins with https://simplemining.net...
I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

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.


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.

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

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.


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.

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.

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.

removed pic for space

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!

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

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.

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?  Smiley
