Intro: Water batterythe idea is to create a battery that works on water.

The concept behind it is to make a galvanic cell that works on either a saltbridge or a sourbridge.In this case it's a saltbridge, but you could try using plants or wine (sourbridge) to create the same effect.-things you need:.copper sulphate.zinc sulphate.water.led lights low voltage (testing).clamp cables.6 plastic bottles (1l).6 pieces of copper.6 pieces of zinc

Step 1: Step 1the first step is filling the bottles with water , i recommend using 1L bottles (6 bottles).put the bottles in a wooden frame so you can move them around easier.

(when you have copper and zinc cut them into 6 pieces that you can clamp onto en put through the bottle neck.


Step 2: Step 2fill the bottles and connect the anodes en cathodes:

left bottle above: add 20 gr of copper sulphateleft bottle below:add 20 gr of zinc sulphatecenter bottle above:add 20 gr of zinc sulphatecenter bottle below:add 20 gr of copper sulphateright bottle above:add 20 gr of copper sulphateright bottle below:add 20 gr of zinc sulphate

each bottle wil produce around 2 volt.

when you have this prepared, connect the copper to the red wire, with on the other side zinc so u will have a + and - side.and put zinc to the dark wire and on the other end copper. you start in the first bottle with copper and the end in the next bottle (zinc) in the second bottle you start againwith a red wire that wil end in the next bottle and there you start again with a black wire. this wil create a electric circuit.

(make sure the clamp cables do not touch the water)

Step 3: Step 3when you finished filling the bottles and connecting the cables you end up with a red + and a black - wire from the first and last bottle.

make sure you cover the bottle neck with a plastic or rubber so that you minimalise evaporasion

measure the voltage using a voltmeter, you can test it by using a led that is close to the average volt that is produced.

in the picture you see a 12volt led burning


Step 4: Step 4by using the clamps you could connect the battery to a charging wire, this makes it possible to charge low a powered object or maybe even a cellphone like in the 3Dconcept.

Roy02 says: May 15, 2014. 6:28 AM REPLYthank you!

Roy02 says: May 15, 2014. 6:28 AM REPLYwill be posting more instructables soon

Roy02 says: May 15, 2014. 6:28 AM REPLYThanks!

Roy02 says: May 15, 2014. 6:28 AM REPLYThank you :)

Roy02 says: May 15, 2014. 6:27 AM REPLYDepens on the materials and water which is different in many parts of the world

Roy02 says: May 15, 2014. 6:26 AM REPLYGood luck, let me know the results

Roy02 says: May 15, 2014. 6:26 AM REPLYThank you!

shawnstecks says: Dec 11, 2013. 9:40 AM REPLYhow long does the battery create a charge?

Roy02 says: Dec 11, 2013. 1:28 PM REPLYdepends on the water (different in each area of the world), the purity of the copper and zinc, i don;t have a exact number but it works until the copperoxidates

Roy02 says: Nov 26, 2013. 12:00 AM REPLY

- Oxidation: Zn ? Zn2+ + 2eReduction: Cu2+ + 2e ? Cu

potential difference

-Zn2+ + 2e ? Zn E0 = 0,76 VCu2+ + 2e ? Cu E0 = +0,34 V

capacity

Q_T = \int_0^t I \cdot dt = p \cdot F \cdot n_m

hopefully this is usefull, you can also look it up under the name of galvanic cell

LexiDelliponti says: Nov 25, 2013. 9:37 PM REPLYWhat is the equation for the battery?

Roy02 says: Nov 22, 2013. 12:01 AM REPLYat any local hardware store


LexiDelliponti says: Nov 21, 2013. 3:18 PM REPLYWhere can I buy the copper and zinc pieces?

billbillt says: Jun 15, 2013. 9:25 AM REPLYgreat
