Alternators have resistance. That is why they require power to turn them. Having alternators on all the wheels would be like driving with your brakes on lightly all the time. That would require more amps to move the car than are being produced by the alternators.

And what E was saying is that basically if you take your 60amp Z alternator and instead of burning gas (L28) to spin it, just turn it with an electric motor. Well, this electric motor would consume at least 70amps to run a 60amp output alternator ... so you have to pull more amps to turn the alternator than it outputs. You don't gain anything, you lose something.
That is why we instead us fossil fuel stored in a tank and burn it up to create engergy to turn the alternator to charge a battery to power our subs and amps for drum and bass. pssssst!

It just doesn't work. If it did, then we would have a 'free electricity' machine. The same thing could be done for houses. That would be great, huh? Electric cars with no emissions and unlimited range never needing to be refueled. Our houses would never run out of power. Our air would be so clean. Planes could fly forever.

 

what, you guys listen to bleach but not me???? that makes me a sad panda .

 

Just because it could be made doesn't mean that it will be made...like the oil companies and power companies will let anything like that get out, they make too much money on our dependance of their power sources. Why do you think it is illegal to make your own fuel and store it...because that is money out of their pockets, they don't want you to be independant. It is not hard to make hydrogen or ethenol...the knowlege is out there and it can be done safely. It is all about money and always will be. Greed is a terrible thing. Why do you think prostitution is illegal? Because they can't tax sex!! So they make it illegal to buy it. Just about anything you can do or make on your own is illegal in some form or another unless you pay some kind of money to get permits, sex, weed, alcohol, fuel, homes....it goes on and on. If you have the knowlege to do something safely why must you pay for permission to do it? GREED!

As for multiple alternators powering one power cell you can use reverse isolators and electronic swithcing to get the job done. You could have an individual cell for each alternator and sum all the cells to one bus to power the car...it can be done. Open your minds and join me in my twisted world....your eyes will open wide!!! It takes very little twisting force or torque to turn an alternator so hooking them up to the wheels will likely not be noticeable and it would still charge even if you let off the "gas pedal" if the car is still rolling. There are really good bearings out there so it would not be hard to make a smoother turning alternator.

 

sexual harrasement...panda, dont touch this dont touch that...sexual harrasement...panda.

when one panda sticks his nose under another panda's skirt, thats sexual harrassement...and that makes m a sad panda. lmao

 

turning an alternator by hand a 30rpm isn't hard.
turning an alternator at 3000rpm (max amp output) is not so easy

arguing on the internet is kinda like... oh, nevermind

 

I don't want to argue brother, just voicing myself. It's all good man. Don't make me build one though....no wait...no yeah I have hit 500 post...I could do it.

 

build me a self-powered alternator. I'll pay you for it.

 

i'll pay you twice what bleach pays.

 

i'll make da money inda bathtub.....that way there willbe plenty for the project.

 

How do we know that would require more amps then the alternators are putting out? Do we even know how many amps the alternators are putting out? Nope.

Kind of reverse thinking on that one. We didnt put motors in cars to turn the alternators. We just used the motor that was already there to turn the alternator so we could now power up and coming eletrical accessories like headlights and in car radios. And who said anything about the alternators we have in our cars? I'm talking a dedicated power generator that can use the benefit of gearing to take the load produced by the charging system and lower it susbstantially.

I dont think its really a matter of that. It's a matter of technology and cost. It's not reasonable to think the benefits of such a system would outweigh the costs. Thats why I stated this was all theoretical. Why go through all this trouble when we can just use windmills to generate electricty without the burden of a self sustaining charging system. Wind is after all a free source of energy. Why incorporate all this weight and cost into an automobile when current means and technology are not only affordable but being excepted on a global scale. There's no need for this kind of thing. It's the same reason electric cars never have and, for a while still, wont do well as far as sales are concerned. How long ago was it that something like a computer was deemed impossible? The world was once flat ya know

 

this wont work. PERIOD.

input will ALWAYS be higher than output.


this dedicated power system would require a consumable source of energy, and NOT a battery that is being charged by this system. and adding gears just adds more resistance, which makes your system even LESS efficient.

your system will always be only theoretical. it does not stand up to the laws of physics. until we have the means to alter the laws of physics, it wont happen. and wind power is not all that efficient. it takes an ENOURMOUS turbine farm to provide a useable ammount of electricity, and wind is unpredictable and unreliable as a source of energy.

sorry j, not trying to be a dick. just pointing out facts.

 

Ok, now chew on this: Suppose the generator/alternator didnt even have to spin. Now we've taken the lost energy through friction out of the equation. Not really suitable for automotive applications but...

Clicky

I guess we've altered the understanding of the laws of physics Renewable energy without a depletable energy input.

 

You Guys Have To Much Time On Your Hands

 

Yes, yes I do

I do not however have a physics degree

And here is an applied application of producing more energy then is being received: http://www.cheniere.org/misc/minuteman.htm

 

Here's another theory: If 3 seperate batteries and a switching system were used then it makes sense that the self charging system would work. The batteries would be in the following states to begin the cycle:
Battery 1: Supplies power to the motors
Battery 2: Holds a full charge and does not supply any energy to anything
Battery 3: Same as Battery 2.

Now start driving the car and Battery 1 starts to drain from supplying the energy to the motors. Once Battery 1 hits a certain level of depletion it's circuit to the motors is opened and it instead now receives energy from the charging system. Meanwhile, Battery 2 is now supplying energy to the motors.

Battery 1: Being charged
Battery 2: Supplies power to the motors
Battery 3: Holds a full charge and does not supply any energy

Once battery 2 depletes it is charged and energy supply duties are given to battery 3.

Battery 1: Being Charged
Battery 2: Being Charged
Battery 3: Supplies power to the motors

Once battery 1 is fully charged battery 2 is then charged and so on to battery 3. And each time a battery is depleted it is taken off of energy supply duty and switched to receiving a charge.

Battery 1: Supplies power to the motors
Battery 2: Being charged
Battery 3: Being charged

3 Batteries may not be neccessary. More then 3 may be neccessary. It would all depend on the rate of charge in relation to the rate of discharge. With this system no battery is ever receiving a charge at the same time it is supplying energy. The system is no longer dependant having the ability to function at over 100% efficiency. Of course this would be dependant on the size and weight of the batteries. They would have to be compact and light enough for mulitple batteries to be used in a car.

 

don't forget--deep cycle batteries--just like a boat--now yer talkin' 'bout lectricity!---need to know how many amphours it takes to run/restore, provide an alternator of appropriate size, run the wires to whereveryou wish to run them-------and have 2 banks of batteries-any number in each bank--so when using one, you charge the other--simple. go figger. and you boyz were getting all twisted up about it!!

 

screw those. this car is running off the top of the line battery tech. LiPo cells. they would rock the socks off deep cycle RV/Marine batteries any day;

 

see, science can be fun

 

i think, we should all agree to dissagree before soemone mails someone else a bomb. lol.
