Ex: run a big cell lets say 50-100plates at 110-115v and 5-10amps to produce 10-12lpm. Now i have not even done the math or anything yet, to see if i am way off base. Just wanted to share my idea and see if anybody with more knowledge than me and give me any advice.

Zack, ANY time you convert any type of power from one type to another you will have some waste in the form of heat. Your power cord that charges your cell phone is a prime example. It steps down 110 to 9 volts and rectifies it to dc. Just feel the convertor box and it will be hot. Unless there are some effeciency gains with your cell to be made by running any electrical device in addition to what you need it should be avoided. It all goes back to how much gasoline it takes to make the current. Running an invertor on your car to create AC will not lessen the load on the alternator because you must measure current not amps. 13.8 volts and 50 amps is 690 watts which would require just over 2 hp from your engine. The wattage is what takes the gasoline to make. 110 volts at 6.27 amps is also 690 watts. Both take the same amount of gasoline to make. The problem is that you will not get 690 watts back out of an invertor from the 690 watts of dc voltage. You will get something less back. Most are not even 90% effecient.
Hope this helps

2008 Nissan Frontier 4X4 Nismo. 12 MPG baseline with my normal commute and heavy stop and go daily driving. Generator installed and working on 3/29/2009
Up to 14.5 MPG with no enhancers. Still testing the effects of lots of HHO and no electronic enhancers.
