"how to create a continuous power source"

Continuous in what regard? voltage, current or both? What kind of regulation/ ripple rejection is also required if any? A 12v automotive alternator is usually factory set for 14.2 volts, bear in mind it needs to have a suitable battery attached at all times while running else alternator runaway. The 12 volt regulators will have to be the LDV type (low dropout voltage) normally u need about 3 v head room for 78xx range of regs. Do you not have access to a power grid? it would be much easier.

Hope this helps

a car altinator will put out up tp 130 volts ac, but you have to bypass the dc components. some where i have a diagram and instructions on how this is done and works ok, i'm 68 and have seen many diff. methods of getting power through diff. means. one is to take any ac induction core motor powered by gas engine and connecting a 150watt lightbulb across the leads then momentarily puting 24 volts (2 seriesed 12v batteries) to creat the induction field and it will put OUT the 120/220vac that it normaly consumed and as long as the minimum required load to keep the induction field going will put out the voltage like a regular generator. choose a motor with the needed amperage as it will put out 75% amp as it consumed as a motor

In regard to getting more electricity from output than input!

If I understand what you are trying to do, you can use either a generator or an alternator (with associated diodes) as a charging source, but as Madness said, the source must be somewhat higher voltage than the battery. In addition to the items you mentioned, you also need some switching device that will start and stop the energy source powering the alternator or generator, depending on the battery voltage and load current.

You did not say what kind of load you are trying to keep operating. That could make a large difference in the kind of regulators and switching devices needed.

Your simplist option is to build the alternator into a battery charging circuit. Modern alternators normally have built in regulators set to 14.5 volts. 12V car batteries are actially 14.5 volts fully charges. To build your circuit you need to connect the alternator output to the battery + and the alternator case to the battery - If there is a terminal for a charge light it goes between that and the battery negative. you take your load power straight out of the battery. the regulator will shut the alternator off when the charge in the battery is full. the load will make teh abattery appear flat and the alternator will 'charge' it up. if the alternator stops the battery will drive the load till it goes flat.

Simple enough?

On a larger scale. one electric motor,low voltage could turn 100 alternators easely. This could power a household. could it not dkwarner?

If you are trying to get continuous power without introducing additional power, forget about it.

I know this. What im working on is to take a low powered motor which turns various more high voltage ac dc components to have a larger power output than is needed to supply the drive.

When I saw your previous post, I thought you were joking...

Now I see that you are talking about getting more power out than you put in. Every time energy is converted from one form to another (eg. a motor running a generator), there are significant losses, not gains.

NO! One motor can NOT run 100 alternators. A 1000 W (≈1.3 HP) motor could run ONE alternator. If it was a better-than-average alternator directly connected to the motor, gthe alternator could conceivably put out 400W of power. The other 600W is lost to heat in the motor, the alternator, the wires, and the air.

Connect that same motor to two alternators, and you'd be very lucky to get a total of 300W out of the two alternators combined. To connect two alternators, you would need pulleys and belts or gears - which lose more energy to heat and sound. In addition, the alternators would have to be smaller for the motor to be able to power the pair, and smaller alternators are nearly always less efficient than larger ones.

You might conceivably be able to get one motor to spin 100 alternators, if the alternators had no loads, but any power you might get out of those alternators would be minuscule, because virtually all the energy would be lost to friction in the gears or belts, bearings, and in moving air through the motor and alternators.

Sorry, but all energy has to come from somewhere. No device or combination of devices can ever be made that continuously puts out more power than it receives.

reading all comments i see what the idea is to get out more than put in, this is the Asyndrom theory and acording to todays and yesterdays science this is a dream and not at all possible, however what was impossible years ago is being done today. i have lived for 68 years and seen the impossible become possible reality. as they say never say never. use your imagination ,expieriment, and some day someone may discover a way and means to do what MANY have been thinking about for a very long time. example: while i was young and working for elgin advanced relays one of our engineers told me he had developed a new battery and was getting it pattened. his attorny did a search and found he could pattend it but attorny was angry. the attorny found that the was a patent for a battery that when completely assembled never went dead but gave out neverending power (a fact), but bought up by one of the battery makers and permently shelved. none of you think of imposiblity but how can it be made posible.

There is a BIG difference between 'impossible', and 'impossible with today's technology'.

I too have lived 68 years, so have seen most of the same advances you have. Dick Tracy's wrist TV was impossible with the tecnology of the time, but is quite possible today. It was not impossible due to any laws of physics, but rather due to the lack of miniature devices like integrated circuits and LCDs.

On the other hand a battery that never goes dead is impossible. (Period) A battery is a device that converts chemical energy into electric energy. A battery can only contain a limited amount of chemical energy, and when that chemical energy is used up, the battery is dead. (period)

No device will ever be made that continuously puts out more energy that is put into it.

Notice that word continuously.

You need several mice (or oxen or elephants or...) to keep that wheel turning continuously. The same Law of physics still applies: There must be considerably more energy in the food fed to the animals than can be produced by the generator/alternator connected to the wheel.

All energy conversions have losses, and there are multiple conversions in this process.

Now you're getting closer! No laws of physics broken there; the energy comes from the sun. Unfortunately, the sun shines only part of the time on any one spot in the temperate zones, so that word continuously gets us again.

That's why it is so important to find ways to store energy efficiently in large quantities. Current batteries don't even come close for large quantities. So far, to my knowledge, the best (most efficient) method is the pumped water storage system. I've seen a fair amount written on air compressed in underground caverns, but haven't seen efficiency figures.

it is in the patent office if you can find it, that battery does exist and does what it claims whether you or me chose to not believe it. gust like the event in the 20's of a tablet that made one gal. of high grade fuel out of tap water (a fact) and the guy disapeared when they tryed to steal the formula from him. this is recorded history. but to add more to the fire, when i was working for pacific test specialties ( crystalite corp. in 70's) i had a fellow by the name of bill diamond a optical scientest, tell me about a blue color quartz from either greenland or iceland from volcanic area that actualy amplified energy. it had been tested that when 1 volt wasput in you got out 10,000. i had found that hard to swallow till when visiting d.c. for a big lapidary shom my boss took me the the new york national museum to to visit the mineralology displays and talk to doc. manson the curiator of that section. i brought up the question of the blue quartz and he said it does exist and a big lab in conneticut was testing it and it does amplify energy and noone can figure out how. they even tryed growing these in labs but they didnt have those properties. fiction today fact tomarro

I'd love to see you prove either of those stories, but I don't expect that to happen.

Now I CAN possibly believe putting 1 volt in and getting 10,000 V out. A pulse of 1 V at an Ampere or so could run a device that strikes the quartz, producing a shorter pulse of 10kV at maybe 1mA or so via piezo-electricity (that's how many barbeque lighters work). BUT, that is NOT energy amplification. In electricity, energy is the product of voltage, current, and time; any one of the three can be increased at the expense of one or both of the other factors. Energy amplification would require that the product of all three factors at the output would be greater than the product of all three factors at the input. The laws of physics regarding energy have been well proven, and energy amplification is impossible, period.

You have been reading too much of something, and too little of physics. With all due respect to Disney, Wishing does NOT make it so!

hi again tell that to the lazer tech's. far more light energy comes out than goes in, if you insist on closing your mind and accepting what the astablishment says, the world will remain FLAT. it is opened mindness that has gotten us this far by not accepting the usual laws, no one should ever lock themselves into a nitch and say thats it. i was sceptical as you on the blue quartz never the less it amplifies energy and thats what the establishment doesnt want you to know because it would loose money and power if all got used. perfect asyndrom may not be posible but gust getting that close would be an achivement. you could get close with super cooling components, etc, but us guy out here will have to be content to expierement with what we have. who knows maybe someone will find that the rule the world is flat can be broken by a rule not yet seen and found , remember its from what perspective your at.

Hello!

With regard to lasers: "far more light energy comes out than goes in". Correct! in many lasers, NO light goes in. Look up the origin of the word (or rather acronym) LASER (and then you'll know how to spell it).

But you MUST look at the total picture for any given device. I understand that solid state lasers are more efficient, but as an example we have a 125 Watt CO2 laser, and it takes over 3000 Watts of electrical power to produce those 125 W of light energy. That is an efficiency of 125/3000, or just over 4%. The efficiency is so low that it requires forced water cooling to get rid of the heat, and the above calculation was just the laser and its power supply. If we add energy used by the pumps, fans, and refrigeration compressor, the overall efficiency drops to around 3%. 97% of the incoming electrical energy is wasted!

I do keep an open mind, and commonly work on things I didn't previously know were possible (I do engineering in aerospace R&D), but again: All energy comes from a source of some kind - it isn't created inside any rock, device, or group of devices.

Nuclear power sources are the closest we're going to get to creating energy, but they don't create it either - they are simply releasing energy stored in them when the elements were formed billions of years ago inside a star or other very large hot object.

Your blue quartz conspiracy theory is just like the fuel made from water theories - wishful thinking.

Please define <...continous...>. Even the sun has a limited life, for example, and that is the most <...continous...> primary source of power that is available with today's technology.
