if posiable this meens u could u could feed 12 volts back to the motor and have 12 volts spare......

We dont even have a machine with efficiency close to 1, you are talking of a machine of efficeincy 2 or more. What of the law of conservation of energy, and mass and momentum?\n\nI don't think it's possible, not in this universe within the limits of the known laws of Physics.

It's possible (but not especially easy) if you have two spark plugs.\n\nOther than that, I don't think it would work.  One lead, check out Onan's web site.  It's www.onan.com/onan/onanengines/ or, just www.onan.com.  But if you find anything, you're luckier than I am.

It should be,if this is the original motor, is 10w30, summer,10w40 or 50 winter(depending on your location). If it is a motor from the mid-80's or newer it it should be a 5 weight\n5 qts.

make sure you have them connect to 12 v, not 5 v, they should run at about 2500

That's one of the best engines on the market today--keep it and have it rebuilt, or buy a "crate" motor to replace it--however, you can put and early model Jeep V-8, or even a Chevy V-8 with an adapter

You would need multiple alternators plus an inverter to accomplish this.  A common Delco GM alternator puts out 120A at 13.5-14V DC at an engine RMP above 3000.  You would have to put the DC through an RV inverter (for use camping where you hook up a battery bank and get AC out).  Assuming inverter efficiency of 85%, you would need 7475 (or more if e is less than 85%) DC watts.  You would need 5 alternators to power your inverter.  The problem is the inverter is VERY expensive, as in thousands of dollars.  \n\nThe problem with using a car alternator as an AC source is it is THREE PHASE.  I have had people disable the regulator and get high AC voltage out, but it is three phase.  You would have a difficult time clocking multiple auto alternators so the phases all matched, and then you would only have 3 phase voltage (probably less than 220V but 120V) and it wouldn't be regulated.\n\nFor 6500 watts you need a belt driven gen head.  See northern tool link to belt driven 25KW head.  Also look at their inverters for taking DC and making AC (yeah, I know--americans use 120 but I'm sure you could find a supplier to go to 240)\n\nBut dollar for dollar, you would spend more to fool around with DC alternators than just getting a gen head which was rated at the wattage and voltage with self-regulation.  ALSO you must REGULATE the RPM.  SO just hooking it to a car engine isn't going to work without a governor, which car engines don't have unless you preserve the cruise control option and hook up the speed sensor (which may give weird results at high engine RPM such as 3600 for 60HZ or 3000 RPM for 50Hz).  NOTE: my links are for 120VAC at 60Hz.  Europe will have different specs.

The quick answer is no, if you could you'd have invented perpetual motion. \n\nIf the battery has a certain amount of stored energy, when it turns the motor some energy is lost (the motor will be about 80-90% efficient) with the same lost in the generator giving and approximate conversion of 60-80%.\n\nThe batteries themselves will also be inefficient in the charge discharge cycle, more so than the motor-generator combination although I haven't found a specific value. However, whenever you charge a battery it gets warm and this warmth is due to energy losses in the charge cycle. \n\nCoupled to all of these would be electrical losses in the wiring, but these would be minimal compared to the other losses.

Yes but you may need a really big sidecar to hold the battery unless you are only going to the mailbox and back.

Good Idea..but probably expensive to hook up the equipment to some sort of generator....gotta keep the place looking clean.\n\ninresponse to answerman....(below)\nIt could be possible to keep a battery bank charged and use an inverter to run a small a/c.\nSort of like a solar setup or windmill.

If its a 12v power supply you need then i think Radio shack should have a suiteable replacement  and they have power supplies with changeable polarity. Ebay has them but a lot of looking to find one .

generally pc work on 18 volts dc not 12 . they actually us e less than 12 volts . but for prop sake and etc . if you can tell the kind of pc you us e i can give you a digram of what to do . dc to dc is not a solution for your problem

It depends entirely on the application for which the motor was designed. \n\nMany very powerful motors (like the starter on your vehicle) are designed specifically to deliver maximum torque for very short periods of time. If you were to continuously crank this type of DC motor, it would burn out quite quickly.\n\nOther motors (like the DC fuel pump motor or the winshield wiper motor in your vehicle) are designed to run reliably and continuously for hundreds of hours without any maintenance (these motors often outlast the vehicle.)

i think it can freeze the motors inside and damage them, if it frezes then you would not be able to move them

You need copper, and any sized battery. Then you need to do some playing around with it. Or you could just go here and do what they tell you.

no u can use the ac power supply it wont hurt it cause that's how u recharge the battery so don't worry about it just use it like that

Putting it bluntly, No.  To create a discharge like that even for a few seconds you'd prob need a battery pack the size of a pickup and it would still be single use.  I'm pretty sure your local law enforcement would frown upon such devices too.......

Could be a good motor. Large displacement modified VWs tend to run hot and could shorten its life.
