Here I show the concept:

This project involves the use of a copper oxide layer and water to create a functional water "battery" that can power an AM broadcast transmitter. Taking the project one step further, the batteries were separated into two packs, with the primary water battery running a simple flyback type NPN based oscillator.
To enhance the performance of the circuit, DC pulses are filtered with one of the electronic lab's on-board diodes before being fed into the base of a PNP transistor, which controls the switching of the isolated water battery 2. The pulses generated by PNP Q2 connected to water battery 2 are rectified back to DC and sent back into the primary oscillator circuits, resulting in a kind of feedback that balances the power supply of the other circuit and keeps the device running for an extended period.
This type of "battery" seems to be able to maintain a charge indefinitely as long as it is pulsed with a short break in between to allow for the chemical reaction to occur. With a week-long runtime, the only maintenance required is the periodic changing of water due to corrosion buildup. Additionally, the device can also charge a single regular rechargeable AA 1.5-volt battery in about a day. This innovative concept has significant potential for various applications in the future.
