I need to name a machine that doesnt use batteries, electricity, kinetic energy or an other energy.....
B.T.W--
would a wheel falling from a hill count???

The name you are looking for is "perpetuum mobilae".
The wheel would not work because it uses the gravitational energy you provided when you moved this wheel up the hill first.

No such thing. Without some kind of energy (rotational, gravitational, kinetic, electrical, mechanical, something) a machine is just an inert object. A machine by definition is an object that does work by converting energy from one form to another.
The closest would be a wheel - it doesn't need batteries or a motor, but in order for it to be functional it has to move (and that is kinetic energy).

It is called a "perpetual motion machine" or "perpetuum mobile". No such machine can exist and the US patent office asks "inventors" of such machines to present a working model. To date not one working model has been submitted. The patent office does not expect this to change.

You need energy to do any work with a machine. So with no energy, you cannot do any work so the only machine that does not need energy is one not doing any work, i.e. don't start your car or plug in your refridgerator, it doesnt need energy to do nothing!

No such machine exists.
