Well. If you like next to lake you can build a small hydropower plant. Or couple 2 3phase huge motors 75Kw to have dynamo machine. You can get car alternators, take a most suitable engine belt and connect generators with the belt like so the rotational pull force would be reduced. Can work with one or two motor.
Or you can make lot of small Heron phountain. It's so water always flow by circulation. I think you need a lot of this for that.
To do this, you need to live on the banks of a river with a good flow and protect this equipment from thieves. If you have real examples of mining on such equipment, then I would like to see it. Such equipment requires the correct location on the river, and its installation would be illegal without registration. Or you can make lot of small Heron phountain.
