AirBat: Electricity From Thin Air

AIR BATTERY, are the batteries which are non-conventional, renewable in which air moisture and water works as electrolyte.I think air batteries are the most convenient battery for emergency, the fact with them is that they can even activate to recharge through saliva.Suppose in your area at night, power cutoff would happen suddenly and you cant get any torch or you cant get a cell to power a torch, may be the battery is dead and you cant light the torch.
In air battery there is always one good cathode electrode which is magnesium, i chose this because this is best and available easily referring to galvanic corrosion chart.
galvanic corrosion chart-

AS YOU CAN SEE MAGNESIUM STANDS FIRST ALSO IT IS QUITE CHEAP AND EASILY AVAILABLE IN THE MARKET.

SO LETS GET STARTED......
FIRST U NEED UNINSULATED 18 SWG COPPER WIRE, TISSUE PAPER, MAGNISIUM RIBBON

CUT RIBBON OF ABOUT 10 CM EACH OF 3-4 NOS(DEPENDS UPON HOW MUCH CELL U WANT TO MAKE), CUT 20 CM OF COPPER WIRE EACH OF REQUIRED UNITS, CUT TISSUE PAPER OF 10 CM LONG AND 8 CM WIDE.

ROLL THE TISSUE PAPER AROUND THE M. RIBBON COMPLETELY.
NOW, TAKE THE COPPER WIRE AND START WINDING IT AROUND THE TISSUE PAPER AND TIGHT THE COPPER WIRE BY TWISTING OR MAKING IT NOT TO LOSE AROUND THE TISSUE PAPER. AND AT THE ANOTHER SIDE LEAVE ANOTHER SIDE A BIT LONG FOR TERMINAL CONNECTION.

DONE!!! YOUR BATTERY SHOULD LOOK LIKE ABOVE PIC. THE COPPER WIRE IS THE POSITIVE AND MAGNISIUM RIBBON IS NEGATIVE.
CONNECT THE CELLS IN SERIES AND READY TO GO.....

ACTIVATE THE BATTERY BY JUST PUTTING FEW DROPS OF WATER!!!!!!
GO AND TEST UR BATTERY!!!
THE ABOVE PIC IS MY PROTOTYPE BATTERY WHICH IS LIGHTING A LED.
