Generators, electric powered

[kmk420kali]

Pardon me if this is something I am just not researching correctly....but has anyone heard of, or know where to get a generator that is ran by an electric motor??
I mean, I have been trying to figure out the most economical way to run one....trying to decide between diesel or propane....then started thinking...if one was ran off of an electric motor...and geared properly, you could use a small amount of electricity to make a large amount--
I am sure they are out there...I just can't seem to find anything on it--
Thanks in advance--

Excuse me if I'm wrong, but I don't think this is feasible. There would be a loss of energy rather than an increase. And how would you power the electric motor?

Good luck, sorry if I'm wrong but I think you might be barking up the wrong tree.

I am not talking about using it because you don't have electricity...
For instance...you have a house, and you want to run 20 1000w lights...but power usage would be a problem--
Lots of ppl do it, and run generators...using diesel or propane engines to power it-- Prob is, it is expensive to buy the fuel-- So what I was thinking is...if you had an electric motor running it...and had it geared properly...you could use maybe 1000w to generate 50,000w-- (Not correct numbers, just for comparison)

yeah i understand what your saying, but how are you going to get a small amount of electricity to generate a larger amount? there will be a loss - in heat, thru resistance etc. there are things called inverters which change, say, a 12v current into a 110/240v, but they are inefficient. i appreciate you are considering gears, small wheel turning a bigger wheel, but maintain there will be a loss of energy. if you could turn 1000w into 1001w then you would have just solved the planet's energy crisis and would be the richest man who ever lived. i think...

on a more positive note, i hear of people running diesel engines off cooking oil, and there is a thing called 'green diesel', which is diesel made from plant matter. i have heard of people running their diesel vans with the oil (sieved) that restaurants discard from their deep fat friers.

if u could run a diesel genie this way then i think you could be onto something. you need to hook up with your local chinese restaurant and take their old oil off them - you will be doing them a favour.

anyway, hope some help. have never heard of a generator run from an electric motor though - invent one!

I don't know what you mean about loss of energy...a generator uses the engine to turn the parts of the generator to generate electricity-- They are separate entities. All I am proposing is to replace the piston engine with an electric motor-- If there are not any out there, I do plan on making one (actually, have it made)....but it is a simple enough concept that I believe it is already being done-- If not...I WILL be getting busy...especially if I just let the "Cat out of the bag"!!

have a look at this: might be some help

1st law of thermodynamics - energy cannot be created or destroyed.

You propose to create energy out of thin air.

Herbie is right. Say I use 1000w to power a generator with an electric motor. If everything was 100% efficient and perfect I would get 1000w out. But in the real world everything is not perfect and some of my energy would be "lost" (but NOT destroyed) to heat, sound, vibration etc. So I may put 1000w in but only get 950w out.

Diesel, gas etc is no different. Say hypothetically a gallon of gas has an energy that is equivalent to 10,000w. If I burn that gas and convert it to electricity in a generator I do not expect to get 10,000w out. More like 9,500w. This is because some of that energy stored in the gas is becoming heat and not electricity.

Another example, you put energy in the form of gasoline into your car so it will move. But this process like everything else is not 100% efficient. In fact only 20% of energy in the gas goes to actually moving the car! The other 80% is released in the form of heat.

Not possible. Mechanical advantage, and efficiency. Nothing is over 100% efficient in real life. There's a lot more, but everyone else pretty much covered it.

Gas, or solar is your best bet. Whichever is cheapest for you-- diesel or propane is what I would go with. Diesel and gasoline engines can be converted to propane, too.. just a fyi.

As already stated bro, there's no such thing as free power. I suggest you read:

this too:

As well as:

http://en.wikipedia.org/wiki/Conservation_of_energy

You can't create energy in your setup (or in any other). You can "lose" energy by conversion to heat due to friction (the movement/turning of the gears).

Before you try anything and spend money in something bound to fail, read up. If what you are thinking was possible I could just hook up two motors with their shafts soldered to each other, turn it once, and they'd spin perpetually if I had the leads of the second motor tied to the first. Which is impossible, since perpetual motion & free energy are bogus.

If you need us to elaborate more just ask, just please don't waste time on something that has been tried and has failed millions of times throughout hundreds of years of history.

This has been discussed in great detail and it just isnt feasible. The laws of physics dont allow it. No offense but do you think you are smarter than the engineers out there?

I know it sounds simple enough, but there is so much more to it. When I first heard it, I though what a great idea, but then it was explained.

Ok cool...it can't be done-- Thanks for the input-- Ya'll seem pretty convinced--

God bless the public school system!

I think the reason people got on you the way they did was because they mistakenly thought the above remark was a smart ass remark, but now we know differently. At least that's the way I see it.

Don't be worried about asking a question, that is why we are all here - to learn. Good luck and see you around!

For some strange reason, the post I made is out of order - what's the deal with that?

Ok...now I'm getting pissed-- What is with the cracks?? I said that, because I asked a fucking question here-- I obviously didn't know my shit...and trust me...this wasn't the only place I asked it-- But I soon seen that I was in fact...in error-- Forgive me for thinking-- You should try it sometime..right or wrong...it is stimulating--

*EDIT-- I really meant to quote the post above this....sorry--

kmk420kali. Tone it down man. You are just being crude. Your idea won't work, and it's proven. END OF THREAD.

Ya, don't tell people they can't defend themselves. I gave that guy K- for being a dick.

I don't think he's so dumb that he needs 5 different people to say no.

Here's everyone after a point: "Blah blah blah I like to stroke my ego"

O btw, kmk, it can't be done

Thanks-- I didn't mean to be a dick...that isn't my style...but yeah...I asked, and I was wrong....I just hope that others don't decide not to ask things they are wondering...just because of negative replies...Fuck tha Haterz!!
