	Subject - science project (human battery) ciavot my daughter has a science project on a human battery. basically an aluminum plate and a copper plate energized by the sweat of ones hands. each set of plates generates about .5 volts. if i wire them in parallel i increase the amperage. what i need to do is raise the voltage, to 1.5 volts. i tried it in series but cant get any results. i may be doing something wrong or this may not be possible. if someone could shed some light on the subject i would really appreciate it. tom Randy L If my mind is on track, you will be limited to what each plate can provide. If you are trying to get 1.5 volts, you will most likely have to get three aluminum plates and three copper plates wired in series. .5 x 3= 1.5? Wiring in parallel will only allow greater current carrying capacity but the voltage stays the same. You should also be able to simulate human sweat with salt water, or water heavy in minerals. It's actually the minerals in water that allow current flow. I saw a practical test on this where power was fed into a container with distilled (demineralized) water. Nothing happened. Then they added salt water and the power went through. Scott Vickrey Wiring batteries in series should definitely raise the voltage. Can you give us some sort of description of what this human battery looks like?
