I hav studied that we can convert a DC to AC. But for perfect AC we need a rotor to rotate around a magnetic field and thus we get AC.There are generators which run on diesel/ fuels in general. We hav Invertors which convert DC to AC depending on their capacity.So why nobody created a equipment which can generate AC without any continuous source like fuels/ Battery.My question is very clear.Is it not possible to create a POWER PRODUCING MACHINE which can GENERATE POWER FROM DIESEL IN THE BEGINNING TO START / BATTERY TO START AND THEN CONTINUOUSLY PRODUCE AC.Just looping the power generated by the generator to AN ELECTRICAL CIRCUIT so that it gets the power and so it can generate more power needed for a full house.Making it a loop.Getting power AS INPUT AND Generating ELECTRICITY.If we have this kind of machine then we dnt need to pay government for the electricity.we dnt need to burn so much coal. If we didnt burn coal for electricity then we can save atmosphere too.Y NOBODY DID THIS?

This has been thought of I'm afraid. Unfortunately, due to the conservation of energy principle, it will not work.
Because energy cannot be created or destroyed, only changed from one form into another e.g. electrical => kinetic then you will never get more energy out than you put in in the first place. This means that you will only ever get the electrical energy equivalent to the chemical potential energy stored in the initial fuel.
Sorry to burst the bubble.
Cheers,

(this is assuming perfect transformation, however you will lose energy to friction, heat, inefficiency etc. as well so you won't even get 100% of the initial chemical potential energy)

Your thinking undoubtedly sound but u have 2 understand some basic functions.
1.AC is not generated, it is DC is generated (Dynamo)& converted 2 AC through brushes (Alternators)from where AC is collected & distributed.
2.To run Alternator, a prime mover is needed.
Your Question is to wipe out prime mover.
It is all ready developed but is so costly that cost of consumer electricity is very high.These are on date fitted in space crafts & known as Solar panels.These solar panels through electrolytic cells generate electricity & charges Batteries.(DC).As per use in space crafts those are converted to AC using investors(Pure sin waves).
Solar cells for domestic use is available & manufactured by BHEL, sold thr' Govt at a discounted non affordable price.
But wait! It will be available soon at lower cost for individual domestic consumption.

It relies upon on financial pastime, with advance of inhabitants centers there's a severe call for for electric powered engineers and the pay is physically powerful. on the different hand there is aways a want for electronics engineers via certainty that it particularly is everywhere no be counted what the financial pastime tiers. whilst situations go undesirable an electronics engineer makes thousands on doing digital fix and improve paintings. i understand I do.

That is another of the famous perpetual motion machines. Since there are frictional and heat losses in the generation process whatever you put in will never come out with as much (or more) energy. It is a dream and never a reality.

You are asking about generation of electricity... and not about conversion from DC to AC...
You cannot generate power out of nothing…
You will have to convert one energy to another that is electric power…
It is not only coal and diesel… now we generate power out of solar energy, wind mill energy and atomic energy… tests are being done to utilise the energy out of the tides in the sea…

perpetual motion machine with increased mechanical friction and core loses will never work
