I want (need) to convert a vehicle for financial reasons as well as green reasons. I need to be able to do this conversion on a very strict low dollar budget. I am trying to source a donor vehicle for as close to free as I can get. I have located a salvage yard with thousands of electric motors (they have no markings and I can't distinguish between a DC and an AC motor). I am already broke, and since I can't and won't borrow from anyone, I really want to make this project out of as much recycled material as possible. This is my green side. I have experience in parts fabrication, but I lack electrical knowledge. I haven't read as many threads as I probably should have by now, but my time is limited. Forgive me if this question is completely ridiculous. If I use capacitors to help run the motor and recharge the batteries, will I get better range? Please don't yell too much. Like I said, I'm not an electric engineer. I can fabricate parts using mills, lathes, drills, grinders, sanders, and files, just don't ask me to rewire your car or house with a schematic (I can't read them). Any advice you can give me would be a help (just don't ask me to give up).
