No. The essential driving force for the wick to lift the liquid is the reduction of the potential energy between the wick and the liquid due to the bonding molecules.
In other words, the process of extracting the liquid from the wick essentially requires consumption at least equal to the energy released by the first.
The fundamental reason why trees can continue to do this is that they use solar energy. Likewise, you can also do this by letting the top part of the strand bask in the sun. Sunlight provides energy for the water molecules at the top to break away from the wick, and the wick will search for water molecules. from the bottom to combine with. The wick can also extract water continuously.
However, as you said, this will not be self-fulfilling. For example, one of the problems is that low pressurewill be generated inside the pipeline. This low pressure is also harmful to the flow of water downwards, does not promote the thrust of the turbine and does not promote the absorption of water at the bottom. fiber. The overall effect is to stop, rather than an effect similar to "loop gain".
The intensity of the magnetic induction of the large magnet will gradually weaken. This thing is no different from hydroelectric power, except it's driven. by a large magnet.
The small magnets on the rotating disk will also be assimilated for a long time in the magnetic field of the opposite magnetic poles, and the intensity of the magnetic induction of the magnetic poles will weaken also until the pushing force cannot overcome the friction force between the shaft and the rotating disc, and the device will stop.
