Powering a wall clock on water.

The really interesting stuff with this sort of setup only starts happening when you get rid of the water. Many years ago i was attempting to test how much gas i could get from a single charged car battery. Looking to have a large area exposed to the water and following the keep it simple system i used 2 baked beans cans one small and one large. I soldered a wire (after filling it rough) to the top of each can and cut the bottom off the smaller can. I used a piece of plastic to set up the small can in the large one so the top edges were level and put 3 spots of hot glue around the edges of the small can top and bottom so it couldnt contact the large one. I placed these in a bucket and connected the battery 20 minutes later the battery was flat and it hadnt really made what i considered much gas if thats what you can call the ooze of yucky greeny grey bubbles it had on top of my bucket. Looking to check the resistance before finishing the experiment, cause you know someone is going to ask when you post results. I chucked the meter on the wires coming from the tins after the battery was disconnected ....oppps i hadnt changed it from voltage and there to my amazement was voltage not a lot but more than the nothing i was expecting. I checked the resistance noted it and removed the cans from the bucket tipped the water out and took them inside. My expectation at this point was less voltage and less until the tins finally completely dried and there was no more possibility of connection from one can to the other so no more flow. I continued to measure the output from these over the next few weeks when i eventually gave up, they were long since dry but still putting out power. I concluded from this that the power must have been coming from deterioration and that the different size of the tins meant the deterioration at a different rate in each was supplying an imbalance and thus allowing the electron flow.
