hello! is it possible to create ac voltage from dc by connecting two electric motors together and putting dc through one?
A DC motor and an AC motor/generator? Yes. But it wouldn't be as efficient as an electronic inverter.
thanks. i need a simple way to convert my 6v dc to AC so i can use a transformer.
An inverter is really nothing more than a highpower oscillator. For mains frequencies, you can often get away with a discrete approximation to a sinusoid (e.g., you can use a staircase approximation). I own an older inverter that plugs into the cigarette lighter in my car. It generates square waves. Ugly, but many appliances don't care.
Google "power inverter" for details. However, unless you are reasonably skilled at electronics, it would be better to buy one.
There are a lot of ways to do it. The easiest way is to get a 6V to 120V transformer, then feed the 6V side with a 6V square wave. You can create a 6V square wave with four switches in an Hbridge configuration. Alternatively use a 6 volt center tapped transformer, connect the center tap to 6 volts in, then use two switches (MOSFETs, bipolars etc.) to generate the 6V square wave. This requires a big transformer but is pretty straightforward. This gets you a 120 volt square wave which is usually enough to run most common AC loads,. but it's hard on motors.
Here are a few designs:

One of these might work, along with a 12 vdc to 120 vac inverter.

i had a crazy inspiration for an experiment. do you know how to get 6.e+120 watts for about 1.1777659001 seconds? i cant think of anything.
fine. for exactly 1.1777659001 seconds
So what is significant about that time period?
because in exactly 1.1777659002 seconds my coil would destroy itself with that much power.
It would be destroyed much, much, much, much .... much sooner than that (the forces would rend the coil at nearly light speed  remember, you're concentrating into the coil 50 orders of magnitude more energy than the total massenergy of the observable universe; that's worse than Ghostbustersbad). That aside, 11 significant digits? Nope.
I'm not sure that it matters. If one assumes that the energy is somehow coupled to the whole structure at once, it disintegrates nearly instantaneously. If one assumes that the energy is delivered to one end of the structure, that end of the structure disintegrates. If the energy propagates down the structure nevertheless, you have a propagating wave of disintegration that still sends coil bits out at light speed.
I think that it's Ghostbustersbad no matter what. That's a lot of massenergy!
no, because this coil is built in special sections, each one able to withstand 0.001 seconds of this power, and only having to deal with this amount of power in them for 0.00099 seconds.
You're not thinking about this correctly. Pause and consider what "50 orders of magnitude greater than the total massenergy of the observable universe" means. It doesn't matter if you build it in "special sections." It doesn't matter if they have to withstand this power for "only" a millisecond or so. The game is over many orders of magnitude sooner than that.
I'll repeat myself until you really pause and consider what "50 orders of magnitude greater than the total massenergy of the observable universe" really means. Your calculation is off by many, many, many orders of magnitude.
If it helps you to get unstuck, write out the number, rather than keeping it in scientific notation.
Or consider this: Concentrating that much massenergy in the volume of a humanaccessible structure will have serious GR effects. You are talking about cramming the massenergy of our universe, and 50 orders of magnitude more universes, into a coil. The party will not last a millisecond. It will not last any time unit that has an official prefix associated with it.
Finally, you have overlooked the obvious: 90 atomic bombs clearly possess much less massenergy than the universe. The energy you are talking about, once again, exceeds the total massenergy of our observable universe by a multiplicative factor of 1000000000000000000000...00000.
i have redone my calculations and i have thought about what 50 orders of magnitude is for two years and i am prepared to work on it for the rest of my life if i have to. (which i probably will)
Look, I'm trying to be helpful, but you are insisting on saying quite ridiculous things. Simply repeating an absurdity doesn't make it sensible. You have obviously never considered what 50 orders of magnitude actually means. Never. I have given you the information you need to figure out that what you are talking about is utter nonsense. It doesn't matter a whit how long you are prepared to work on it. What you are saying is actually much more grandiose and absurd than "I can carry the whole universe in my finger. Don't bother me with facts. I am prepared to work on it for the rest of my life if I have to."
That's because you don't understand it. if you saw the blueprints and calculations i (and 12 others, 10 of them unknowingly) have done, you would understand.
I am basing my conclusions entirely and solely on the numbers you gave. If the power and duration are what you wrote, then everything I wrote follows necessarily. Period.
To refute my conclusions, you'd have to revise the power and duration numbers you typed. It's really that simple.
the numbers i have provided are correct. however, i have not given you all the information because the people would steal my idea.
Then my conclusions are correct as well.
Sorry, but that doesn't fly. You've confirmed that you did not commit a typo in writing the power and time numbers. That suffices to compute the total energy required. I have pointed out (repeatedly, and with your tacit agreement) that the total massenergy of the observable universe is much smaller than your requirement by an inconceivably large factor. Therefore, to continue asserting that "additional information" would overcome the objection simply makes zero sense, for it's the equivalent of asserting that this additional information would suddenly create more energy than exists in 10E50 universes. That puts the idea into hardcrank territory. You are certainly free to believe as you wish, but make no mistake: Your idea is pure bollocks.however, i have not given you all the information because the people would steal my idea.
