I have started printing the case blanks for the bio reactors. I will need several to chain together. When I get the copper and zinc wire I will be able to do initial tests to see how much voltage is produced.  The most possible is about 1.2 volts per cell , but given that this is a aqueas cell where the medium has water has a carrier , the voltage is lower per cell, likely .25 volts if I make a guess. We shall see in the first tests. I need to produce at least 13.8 volts under load ( not free voltage direct to meter without load). It would be pretty stinking cool to be able to charge all my phones and batteries for robots from GREEN power. :)

At this time 6 Cell’s are printing and they will be finished likely before I head to work in the morning so I can start another set printing. These cells could certainly be scaled down to as little as 25 percent of the current size , so I am making the STL files and other parts completely scaleable so you can GO BIG or just to a science project.
