no, it would be a violation of Newtons third law...it would have to generate more energy than the energy it uses
For every action, there is an equal and opposite reaction.
I think it is. I think about satellites. The definition of a pmm is once you start it you don´t need any extra power to keep it going. Satellites don´t get any extra power after they have been launched. gravity does the rest of the work for eternity as long as no meteorite crashes intothe satellite.
Perpetual motion machines have fascinated people for centuries. However there are some scientific reasons, at least for now, that this would not be completely possible. Here's a deal: You get the law of conservation of mass/energy repealed, and I'll build your perpetual motion machine.
The teacher said he had to build a perpetual machine. Of course he was wrong about that.

Albert Einstein certainly did not build a TIME MACHINE, nor has anyone built a TIME MACHINE. However, Einstein's theories do give us a better understanding of time, and do show some possible ways of changing the speed at which time passes for a given person (if you travel in a space ship at close to the speed of light, time will pass slower for you than it does for people left behind on Earth, and you will effectively travel into the future, while simultaneously traveling to a distant location in space).
jack oxenham and sophie jewell tried but they failed SP4L
you win
it depends on what you use to build it

If you are suggesting a "perpetual motion" scenerio, it would violate the first or second laws of thermodynamics. Many inventors dream of perpetual motion machines, but they are an impossible dream according to the laws of thermodynamics. The second law of thermodynamics says that an engine or process of any type must always have an efficiency of less than 100%. A perpetual motion machine that uses a generator to power the motor that runs the generator requires both the generator and motor to operate with 100% efficiency. This type of perpetual motion machine does not violate the first law of thermodynamics, but violates the second law of thermodynamics. It is a perpetual motion machine of the second kind because it violates the second law of thermodynamics. Not even the cleverest engineer or inventor can build a perpetual motion machine because it would violate either the first or second law of thermodynamics, which are fundamental laws of physics.

Well anything is possible if you put your head to it!
It is not possible to build a time machine. So NO it is not easy, it is impossible.
Its already been done! Just leave it in the microwave too long??
The term "gravity generator" seems to be used for different concepts. The first hits in Google are related to machines that purport to provide "free energy", in other words, a perpetuum mobile (perpetual motion machine). Such machines are not possible to build - there are good reasons to believe that the Law of Conservation of Energy is valid, in other words, you can't make energy out of nothing. You can see many such designs, and explanations of why they don't work, if you search the Internet for "the museum of unworkable devices".
There is no such thing. There is no such thing. 1) It costs money to build any machine; you can't build a machine for free. 2) But pressumably, this refers to get energy where there was none before; this is not physically possible.
That was a fiction machine. We do not think that is possible to build.
The question is a bit ambiguous. I'll assume you mean "What conditions have to be fulfilled in order to build a time machine".It would seem that it isn't possible to actually build a time machine. So far, this remains the realm of fantasy and science fiction stories.
