Heya all

Im just wondering how compplex it would be to build a massive version of this : (Imagine car battary size ?)

**broken link removed**

Also could anyone tell me about the power output i could expect ?

Also could a Citrus liquid be used to create a power source ?

I can tell you that it's not powered by water - is that any help?

The "water powered" battery is actually powered by the electrodes which are consumed during its two year life; the water is actually only the electrolyte. The devices that it powers (calculator, clock) only require a few microwatts. To get car battery power levels (hundreds of watts for $50) you would need to connect a million of these ($5) "water batteries" together.
