for now, you cant, because 100% efficient machines havent existed yet. primarily the inevitable presence of friction.

In reality, there cannot be such a model. The scientists once invented a rolling mill with balls in each internal baffle. That ran for years together, but slowed down with time.

When the concept of Friction = 0, the never ending energy source from a closed system can be created.

In short the answer to the question is no.

What you are asking is whether a source of energy can be created that will be useful for ever?

A source of energy is some system which gives energy in a form usable by us, from another form of energy or from mass. One of the basic tenets of the laws of physics is the conservation of mass-energy. So, energy can only be converted from one type/form to another or to mass. And since the total mass-energy of the universe is constant, it is not possible to create energy out of nothing. Hence, any source of energy has a finite lifetime as the input can only be finite.

There is no such thing as a source of energy ... energy exists in various states throughout the universe we just convert some of it into usable power for our own humble purposes. By the same token since energy is never destroyed it is in essence never ending to begin with.

If you mean can you create something that converts energy to usable power that requires 0% input after the process is started ... mmm good luck. If you do you'll be a marked man.

Search for "N. Tesla" for more info.

For now,we can't.But scientist are trying hard to get never ending source of energy from the spinning of matters and particles.From the spinning of matters we can get zero point energy.
Check on wikipedia about zero point energy and you will know more bout it.

oh yes, as riddle said. You can create devices do such things but remember that these devices consume energy too so it is rather difficult indeed to make a energy-loop
Universe is hiding secrets and human ability is infinite (maybe ^_^), so I am not sure whether we can do it
But at this time, we can not

sure u can. the law of conservation of energy says energy cannot be created nor destroyed. you can only transform it (i.e. electrical, mechanical, light, sound, nuclear, heat, etc.) which actually makes a loop. so if you can make a device that transforms these energy back into the type you want, then theoretically its possible. but i doubt it, practically.

Not if you plan on obeying the laws of physics.
