Even now in villages people use woods to carry out there energy needs(fire,cooking). So that leads to a lot of ash production as byproduct and the villagers throw them as its of no use. Chemically speaking ash is a mixture of carbon,sulfur and oxygen, in molecular level it contains salts of sulfur,nitrogen and sodium. The project I am gonna explain to you is quite simple. It uses the principle of simple galvanic cell and hence only require a few things.
1)Some coal ash(its the best) or any other ash like wood.
2)A non conductive container i.e a plastic container.
3)A copper and a zinc rod(it can be found in school or collage physics lab).
5)A voltmeter(it can be found in school or collage physics lab).
Now after you have organized all of above,its time for some science..
Step 1-mix the ash and water in ratio of 1:2 i.e for every one kg of ash use one liter of water.
Step 2-pour this mixture in the plastic container and then place the two rod's in such a way that they do not touch each other.
Step 3-now the copper will act as positive charge and zinc an negative charge..so connect the wire on the two rods and then connect them with the voltmeter..
Step 4-as soon as you connect the wires to ammeter it will show deflection, not much but at least 1.0v-1.5v, that's enough to light a small led
Now if you want to produce more electricity you can just connect more cells in serial combination, it will increase the voltage output, if you connect 4-5 cells it will be enough to power a small LED for 3 hours continuously. If done on a bigger scale it can do wonders. Now after this process the ash and water mixture can be used as a fertilizer cum insecticide.

|ASH has a variety of advantages over other sources of energy.|
Some of these being:
1 Wide Availability
3 Easy to Handle
4 Less pollution
6 Negligible waste produced

|Hi I have done your project 'electricity from ash'. I have usde LED bulb and it was lightening. Now I have to do it on a bit higher level. So I want to ask you that how can I produce more electricity so I can light a ZERO volt bulb. I have already used 6 containers each with 450gm of ash.So please let me know about it. My name is Jay Mehta. I am in std.7. So please help me. Thanks.|
