First of all the generator will have an initial cost of purchase and then running and maintenance. Not many generators are fit for constant running, so a typical cheap stuff won't cut it you'll need an industrial or military grade gear. What is more a small generator with low wattage will be much less efficient than a big one, so buying it for a small mining farm is a waste of cash.
There are special kits that allow you to use propane as fuel. If you really have to use a generator buy this kit, it's much cheaper.

Well if I only had a few miners, some friends, exercise bikes, an alternator and a few batteries I could use it as a temporary power source to save some electricity.

Power the batteries to full charge, mine with it, exercise a bit to get some more hours, switch back to paid electricity, repeat.

It's something at least haha.

I may just try this for fun.
 Maybe get 4 or 5 100 amp hour car batteries for 4000-5000 kwh.

Just take a few regular bikes and take the wheels off, have the front sprocket about 10 times less teeth then the rear sprocket for speed.
Have that spin a homemade generator (basically magnets moving across some wire coils) and power the batteries.

Hook it up to an ant s3 for a while and see if I can get it to work.

Ah ok I understand now.

You know anything about the wood gas method?

The generator wouldn't work? Why?

And yes I know it would require more then 1 person to build up the energy needed to charge the batteries. But I know you can charge batteries with exercise. Just depends on how much is needed.
Well, if you want to run a couple stick miners that would be fine. Look at the chart, a healthy human can provide 0.2HP (~150W) for a little less than three hours. If you wanted to something like a single Antminer S5 (~600W), you would need five people (~750W pedal power to get 600W electrical power) working together in three hour shifts to the point of exhaustion. That'd be 8 shifts a day, or 40 people if they can do the 3 hour shift every day.
At $300 and current difficulty, all that would produce $3.68 per day.

The gas generator would only work if you have free gas. I would guess even with free gas you might be underwater just with genset maintenance and repair if you're using a small ~1000-3000W model.

You could have 12 batteries hooked up to your miners on one end and an alternator on the other end. Then the alternator converts the energy from let's say 20 stationary bikes to stored energy in the batteries. So the bikes don't power the miners directly, but are used to store energy in the batteries. Then you just advertise "free gym" haha

So I have a few mining rigs and was thinking about ways to make them cheaper. I thought about using a generator or possibly a series of batteries with an alternator hooked up to something like a workout bike.

I'm not sure how difficult these would be to achieve but I know the workout bike would most likely require a lot of exercise (probably more than 1 person could do). Maybe if you owned a gym? Or thousands of hamsters on their wheels.

But for the gas generator, has anyone tried this or know if it would be cheaper to pay for gas to keep it running?

There's also a way of using wood gas to run the generator I think but that might take some time to "refill" or loss of power etc.

Basically I'm asking which method would seem more reasonable to power miners?
Neither.
