1 cell will produce 0.8 volts and 12 milliamperes.
it will be in dc
I will hav approx 200 cell like this in 1 system
I wll be using a dc to ac converter to convert it
so my questions are
1) shd I connect cell in series or parlell
2)If i want to run a computer(I think it will take 120 volt n 2 amp ac )how much dc curent n ampere shd I produced

Scientist have not got all the answers as some of the cluest machines came from the australian back shed and the back yard aussie inventor is one to tangle with like a king brown snake .To all you people ,it is a world effort to combat carbon emissions.It is wasting money and a carbon resouce that flows out of a vehices muffler as my idea for a carbon filtration unit is that this carbon filtration unit collects the carbon in a way that the carbon can be made into carbon products that can benefit the community and the amounts of carbon collected could build houses ,cars ,motorcycles as the list is endless .?Just imagine machines that look like big jet engines that sit high above city collecting carbon emissions and processing the carbon emissions into carbon product.What a free resource of material?back shed cant be beaten

My system power requirement is between the range of 6.5V to 24V @ 0.8mA w/ GX1 200MHz, in my research I found a 4-cells of battery pack (each cell is 3.6V@ 1.8Ah and 500mA), can this be used for my system? How do I know this battery pack can last for how many hours? What is different between 1.8Ah and 500mA?
