Science is a miraculous thing, If you have the right information and follow the right steps, there is a lot of energy to harness around you. All you need is the key to access that energy. And this post will walk you through all the steps to harness free electrical energy. This free-energy can further be applied to power up many devices and circuit.
Things you will need:
- Container with removable lid (10-pieces)
- Aluminum and Copper strips (Act as the electrodes)
- Metal Cutter/Scissor
- Connecting Wires
- Bleaching Powder (Calcium Hypochlorite- Ca(ClO)₂)
STEP :: 1
Take the containers and remove their lids. Make 2 holes in those lids using screw diver of about 5mm to 8mm. Put aluminum strip in one hole and copper strip in another. Make sure it is long enough to touch the base of the container and bend it from the top.
STEP :: 2
Cut the aluminum and copper strip with the help of a scissor or cutter. Make sure the dimensions of those strips should be equal. As you can see from the above image, the dimensions of the stripped wires is 70mm and 10mm, i.e. (7cm x 1cm). However, you may cut it according to the size of the container. If it is 4cm long cut around 6-7 cm long strip i.e., 2-3 cm longer than the length of the container.
STEP :: 3
Join those electrode in series i.e., connect the aluminum strip to the copper strip of another container with connecting wires and so on, thus leaving the first and last electrode disconnected with any electrode. The two electrodes, one of the first and second of the last are the end terminals of the cells,i.e., the aluminum electrode is the cathode (-ve) and the copper electrode is anode(+ve).
STEP :: 4
Put about 50-70 grams (a tea-spoon) of bleaching in each container and then pour water in both the containers. Now, stir it well until you get a uniform solution and then dip those electrodes and tighten the lid.
Each cell will produce about 1.3 to 1.8 volts depending in the concentration of bleaching powder in the cell. The current flowing will be about 300mA to 600mA in each cell.
Hence, 10 such cells in series will give you about 13-18 volts and the current will be about 3-6 ampere.
STEP :: 5
Along the positive and negative terminals of the cell you can connect any circuit. It just works like any lead/acid battery. But the only difference is it’s free energy which can lit up basic devices. This generated DC voltage have many implications. Use it directly to a lit up several 1watt LEDs. The schematic for LEDs is here:
If you want you can also use this DC supply in a low power Inverter circuit. This DC power supply was used to charge my laptop which requires 40watts using a self made Inverter Circuit (on the Bread-Board).
