I was thinking about buying used car batteries from the junk yard and connecting them with jumper cables then testing the connected batteries with a battery tester to see how many volts it has. I havent tried this yet so I dont know if it will work do you guys have any idea on how to make a generator so I wont have to pay for power
Answer
To make an electrical generator, you need to have a length of wound copper wire rotating inside a magnetic field (refer to elementary physics).
Gasoline/diesel/etc. generators run basically like your car's engine, but instead of turning wheels, it uses the motion to rotate the wire inside the magnetic field, producing electricity. Remember, energy can't be created or destroyed. The chemical potential energy in your combustible fuel is being converted to kinetic energy, which is being converted into electrical energy.
A wind turbine is more "free" in that you don't have to go out and buy drums of oil to make your electricity. But it works on the same principle, but in this case, it's the turbine blades catching the wind that spins the copper loop, creating electricity.
As far as your batteries go, you may be able to store it there, but to charge any battery, from AA to car, you need the correct circuit and voltage, or nothing will happen. So you probably can't use your batteries. But if you can, all that you an do is store the potential energy there, and use it at a later time.
But if you just want to play with making a generator, try this:
First, you need to choose the energy source that you want to convert into electricity. You can use a stationary bicycle, a water wheel, wind turbine, a bored child willing to do some menial work on a set of gears, or virtually anything else with a rotating axle. You do have to choose the source, because as I said - you can't get energy from nothing.
Take that copper wire that I talked about, and make that loop that I also talked about, but leave two ends free (you need that to form the electric circuit). The larger the number of turns in the loop, the more electricity you can generate for the same amount of rotation. Kind of like an electric pulley system, to use a bad analogy.
Take your loop, and connect it to your energy source. You need to be able to rotate the loop end-over-end, without twisting the two connecting wires about each other, because if they do, you'll get a short circuit, and boom, it's done. One way to successfully accomplish this is to connect one wire to the rotating axle and the other wire to a conducting "brush" that maintains contact with a second conductor.
Make sure that you've sufficiently supported the loop so that it's out of the way of any moving parts of the energy source (such as your legs and the pedals if you pay a seven year old to ride a bicycle that never goes anywhere - give them one of those hand-held video games, they'll never notice). To make sure that you get this right, you may need to reinforce your loop with plastic or another light (but sturdy) material.
Grab some magnets (permanent magnets), and arrange them around the loop so that the loop can rotate freely between them. Take care to ensure that you arrange the magnets to maximize the field strength. One good and simple method is to make the south end of one magnet face the north end of another.
Stick the two conductors on your energy source to a battery, circuit, chainsaw, whatever it is that you want to drive. Again, you need to keep your wires separate to avoid a short circuit, so you'll need to use some kind of brush mechanism again, or whatever more clever thing that you can come up with that I haven't considered.
Poke the kid and get him to start peddling, or release your turbine to the wind, whatever you want. The amount of energy that you get from your turbine will depend on the efficiency of its construction, materials used, and how much mechanical energy us put in to drive it and spin the turbine itself (a faster peddling kid will give you more electricity than a slower one).
Run with it. A home-built turbine is unlikely to provide your house with any really useful power, unless you've really taken some time, money, and thought into it (which is possible). But you might run some simple things from your standard knock-off generator, such as perhaps basement lighting, that kind of thing.

does this car on craigslist sound like a scam?

here the message they sent to me--
"The car it's still available, has 82,947 miles, manual transmission. It's in perfect condition, no engine/electric problems (4 Cylinder 1.8 Liter Turbo), no accidents/liens/loans. Exterior no scratches, never been repainted, interior no rips/tears/stains, never smoked inside. I have all the car's manuals, 2 spare of keys, title,documents. I'm selling the car because my child of only 19 died 4 months ago in a car accident, a drunk driver hit him and his fiancee. He was with his fiance's car coming to our home at his little brother birthday of 10 years old. This VW Golf was his car and it brings me bad memories and that's the reason I want to sell it. The last price is $2,900.
Me and my husband travel a lot with our business and we want to make this deal through eBay's Vehicle Purchase Protection Program. I just need your full name, full shipping address, home/cell # so I can open a case (with no further obligation or fees). eBay will contact you with all the Transaction/shipping details you will need. We will take care of the shipping, so don't worry.
We hope to hear soon from you."
i have a strong feeling this is a scam what do you think?
Answer
Are you kidding me ?
Can you read ?
eBay DOES NOT HAVE a Vehicle Purchase Protection Program
OFFERS TO SHIP CARS ARE 100% FRAUDULENT
You can sidestep would-be scammers by following these common-sense rules:
DEAL LOCALLY WITH FOLKS YOU CAN MEET IN PERSON - follow this one simple rule and you will avoid 99% of the scam attempts on craigslist.
NEVER WIRE FUNDS VIA WESTERN UNION, MONEYGRAM or any other wire service - anyone who asks you to do so is a scammer.
FAKE CASHIER CHECKS & MONEY ORDERS ARE COMMON, and BANKS WILL CASH THEM AND THEN HOLD YOU RESPONSIBLE when the fake is discovered weeks later.
CRAIGSLIST IS NOT INVOLVED IN ANY TRANSACTION, and does not handle payments, guarantee transactions, provide escrow services, or offer "buyer protection" or "seller certification"
NEVER GIVE OUT FINANCIAL INFORMATION (bank account number, social security number, eBay/PayPal info, etc.)
AVOID DEALS INVOLVING SHIPPING OR ESCROW SERVICES and know that ONLY A SCAMMER WILL "GUARANTEE" YOUR TRANSACTION.
