Discussion Overview

The discussion revolves around the concept of self-reliance for energy needs, exploring whether anything can exist that does not depend on external energy sources. The scope includes theoretical considerations and conceptual clarifications regarding energy dependence and self-sustaining systems.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions the existence of anything that can be totally self-reliant for energy, suggesting that this would imply the creation of energy from nothing.
  • Another participant mentions that even the sun, which produces vast amounts of energy, relies on burning hydrogen and will eventually stop producing energy when its hydrogen is depleted.
  • A different viewpoint suggests that the question may relate to the concept of perpetual motion, indicating a need for clarification on the context of the inquiry.
  • One participant proposes that an electron in a stationary state within an atomic orbital requires zero energy, although this is contingent on the chosen model of atomic structure.
  • This same participant expresses uncertainty about the energy requirements for a charged particle maintaining a circular orbit in a magnetic field, noting that while the particle may not require energy, the magnetic field itself does require energy to be created and sustained.
  • A disclaimer is provided by a participant identifying themselves as a non-professional, indicating a level of uncertainty in their contributions.

Areas of Agreement / Disagreement

Participants do not reach a consensus, as there are multiple competing views regarding the nature of energy dependence and the possibility of self-reliance in energy needs.

Contextual Notes

Limitations include the dependence on specific models of atomic structure and the unresolved nature of energy requirements for charged particles in magnetic fields.

What is the word for something if it is self-reliant for energy needs to work?
 
Physics news on Phys.org
Interesting question, but strictly speaking there is nothing that can be totally self reliant in energy needs cause that would essentially mean the creation of energy from nothing. Even the sun relies on "burning" hydrogen to produce the vast amount of energy it does, when the hydrogen in the sun will be depleted it ll stop producing energy.
 
Context matters, but it sounds a bit like you are referring to perpetual motion.
 
an electron in a stationary state in an atomic orbital requires zero energy and depending on what model you choose you could say it is moving in an "orbit", I use the term loosely.

not sure but I think it requires no energy for a charged particle to maintain a circular orbit in the classical sense in a magnetic field altho the magnetic field takes energy to create and sustain.

disclaimer: non-pro attempting an answer.
