If you have a box receiving as much energy as you wish, does it break the law of conservation of energy?

Question

There is a twenty inches box which can be switched on the electric power supply. It can "work" for any time, it consumes much more energy (electric supply) than all of the losses (friction, radiation, vibration etc.) It does not store the energy, you can retrieve only a small amount. I really want to know weather it infringe the law of E.C. or comply - and I miss. I guess this "box" transforms the energy into an unknown form otherwise it could eliminate the whole energy of the universe -theoretically during a very long time period. If I get serious answers I will put it (pictures and some comments of it's principle -which is really simply) up to the net in some days.

Answer 1

If it does not store energy and does not transform it into heat or any other form of energy, then yes, it violates conservation of energy and is impossible to construct.

Answer 2

It is impossible to build such a box. Think of an electric oven. It takes electrical energy, converts it into heat energy but does not get infintely hot or cause space around it to get infinitely hot due to some energy loss. I would have to do some digging through my bookshelves to verify but I think it was Planck (maybe) who had a similar thought problem. Energy is transmitted in waves or quanta. Only quanta of certain aspects, or energy of certain wavelengths, can exist in a given system. The don't fit if they're not the right size/amount. So, not all of the energy supplied or generated by the outside source will be the right size/amount to even get into the system as a whole unit or quanta or wavelength.
Okay, it's been years since I read the aforementioned book, so i will do some digging and email you with a more complete answer.

Addendum: I have the intelligence to learn and understand new knowledge and information, someimtes I just wish I had more genius in me to recall that information when needed.
Anyway, yes it is Planck and it was a problem with an oven which caused him to come up with the beginnings of the theory of Quantum physics. [I am somewhat ashamed I have the screen name I do and could not recall this information :P]

Answer 3

The law of conservation states that the difference in energy must be dealt with; as much energy goes in so much must go out in various forms or be transformed into matter. So, if that energy is not going out in any way, and if there is no matter being built out of subatomic particles, then it is in contrast with the laws of conservation.
