  • Can't hear a darn thing?

  • @Ozarkorganicshiitake That's because there's no sound. You have an impressive power of inductive reasoning.

  • what did you mix in the water salt ?

  • @TheMRGHABRIEL What is 'water salt'? I've heard of salt water. If that's what you meant to write then nothing. It is just salt water. If you read... well, ANY of the comments already made on this video you can see that it is plain salt water.

  • no what i mean is ill try it to charge a car battery it self only,(w/o the car)and ill use it with an inverter to use it in my house electricity,,

  • @ghoku14 Well it's doable, but not worth the effort. You have another problem; ALL household appliances run on 120 Volts, although very few amps. Now, I don't want to shut down your dream; but neither do I want you to start an electrical fire.

  • good work. but as we know solar cell do work with out water :( if you can made that so it will more help full for me because in my country electricity go for 10 to 14 hours daily and solar cell is so expensive here.. :(

  • @ghoku14 So, to get the right values for your car, you're going on the order of hundreds of cells.

    This is all assuming, however, that you have a gasoline engine. Electric engines are completely different and require completely different Voltages and Amperages. My suggestion to you is to not mess with this, you'll probably end up burning out your battery; instead, take the thousands of dollars you'd end up spending on copper and buy a bike

  • @ghoku14 Well, as you can see from this video, the cells are unspeakably inefficient, and produce only 1.5 milliVolts. A car battery needs 12 volts. You do the math. The other issue you face is Amperage; the cell only put out 15.5 milliAmps, and a car requires 2 Amps. If you do the math, you'll realize that either you'll get too low of a voltage or too high of an amperage; to get the right numbers you have to wire the cells up differently; as in, wire them in series or in parallel.
