I read your comments, my hair didn’t stand on end. Guys, no one has yet repealed the law of conservation of energy, all these theories about the existence of ether and the ability to draw infinite energy from air, ether, shit, etc. are just tales for fragile minds. For hydrolysis, energy is also needed, batteries are consumables. Windmills and solar panels are the most promising direction, but here there are difficulties, again, it is necessary to somehow accumulate energy. You can only wind the coil and get free electricity while standing under the power line ... As for mining, it will have the right to life if it only evolves from the useless conversion of electricity into heat, into something more serious, for example - rendering of 3d scenes or a supercomputer.
