Salt Water and Aluminum Foil Night Light - Instructables

http://www.instructables.com/ Fri, 01 Jan 2010 16:47:53 -0800

This circuit has many drawbacks but it eliminates the need to build a circuit or run down to Radio Shack, although obviously for a science fair project one would presumably build a simple joule thief/recharger circuit. The design can be scaled up with additional cells wired in series or in parallel to increase ... egbertfitzwilly (author) kclo421122 years agoReply. Its not a galvanic cell, there is only one metal ( Aluminum ) which reacts with a saline solution. There is an excellent explanation ...

Electrochemical cells are classically prepared with a pair of electrodes made of different metals to establish a potential difference and drive a current, such as in Alessandro Volta's original copper/zinc battery built in 1800. But David Avnir and Ofer Sinai ... simple electrochemical cell. The researchers inserted the fabricated electrodes into a lemon, which served as the electrolyte solution, a tactic commonly used by schoolchildren to build circuits for science fair projects.
