I just say an article about IBM usibg salt as a battery. Maybe it is based on this experiment.

I have changed electrodes to carbon one's.

But still it is no enough to power supply MCU. Here is example of start atmega328 with 128 kHz clock circuit with simple LED blink program. This salt water cell allow to supply this circuit for the while.

Dear Friend,

This is great.....

Yes, it looks like that usage of proper material for electrodes and their shape is one of important thing to get good results from this type of salt water cell.

If you mix salt water with fresh water it is possible to extract energy (without consuming metal electrodes) - Google "salination energy"

The current can be increased by increasing the surface area of the electrodes and the internal resistance can be lowered by decreasing the distance between the electrodes.

Salt water cells are cool ideas to help spark interest in students. I used to supplement my lesson plans in a technical school setting with little experiments to help get students poor interested in electronics. I would build and demonstrate various methods of generating electricity, like build different batteries, including salt water cells.

Interesting idea [mention:4966e6ad97f64dac9ea8919abb220e1d:e9ed411860ed4f2ba0265705b8793d05], the salt water waste stream is an excellent source of potential energy, assuming that the cell material (electrodes) are not quickly contaminated by the waste products in the stream.

Interesting Idea.

I was thinking of using salt water waste from a water softener purge to collect the current.

If you want to pursue this idea, you need to put your cell under a load and see how much current you can produce and for how long.

Once you have that information, you can assess how well a basic saltwater cell could power a given circuit.
