Mechanical electricity generation

Click For Summary

Discussion Overview

The discussion revolves around mechanical methods of electricity generation that do not rely on permanent magnets. Participants explore various mechanical processes, such as wind, hydro, and steam, and consider alternative mechanisms for generating electricity without permanent magnets.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant questions whether mechanical forms of electricity generation can exist without permanent magnets, specifically in the context of wind, hydro, and steam processes.
  • Another participant suggests that generators typically require field excitation, which may not be achievable without an electrical source, thus complicating the generation of electricity without permanent magnets.
  • Some participants mention specific devices, such as Van de Graaff generators and piezo generators, as potential non-magnetic methods of generating electricity.
  • One participant proposes that mechanical means can generate static electricity, which could be stored in a Leyden jar and used to create an electromagnet, ultimately generating current.
  • Another participant discusses the concept of using a large mechanical storage system to produce electricity, arguing that it could provide a consistent energy source without reliance on traditional fuels or renewable sources that are variable.
  • A later reply challenges the feasibility of the proposed mechanical storage system, invoking the conservation of energy principle and dismissing the idea as not useful.

Areas of Agreement / Disagreement

The discussion contains multiple competing views regarding the feasibility and methods of generating electricity mechanically without permanent magnets. There is no consensus on the validity of the proposed ideas, particularly concerning the mechanical storage system.

Contextual Notes

Participants express uncertainty about the mechanisms for field excitation without permanent magnets and the practical implications of the proposed methods. The discussion includes references to specific devices and theoretical concepts that may not be universally accepted or validated.

I was just thinking last night about the generation of electricity.

Are there any mechanical forms (as opposed to chemical or solar or other) of electricity generation that are not ultimately dependent on permanent magnets?

If we had no permanent magnets, would we have any way to generate electricity from mechanical processes such as wind, hydro, steam(coal, thermal, nuclear) etc.?

Generators typically use some type of field excitation to generate electricity, not permanent magnets. Of course that assumes that one has an electrical source for the field excitation. If no electrical source is available, then I can't think of anyway, without permanent magnets, for field excitation (excluding chemical like you stipulated).

These seem to qualify

Van de Graff generators.
Piezo generators
 
Look at this stepwise:

First there are mechanical (non-magnetic) means of generating static electricity See http://en.wikipedia.org/wiki/Electrostatic_generator. Once you have found a way of generating static electricity, you can store the charges with a Leyden jar, which is essentially a capacitor.

So once you've got a primitive capacitor you could connect it to a circuit as a voltage source, which you can then use to make an electromagnet. And from there you can use the electromagnet to generate current. Of course once you've got a charged Leyden jar you could already use it as a current source.
 
It is possible to use a large mechanical storage system, by using a small amount of electicity and store it in large knetic storage unit and then itcan be used to produce largrer amounts of electricity. This is totally Green electricity and does not require nuclear dirt, polluting fuel burning, sun that does not always shine, wind that is not constant, nor water that can freeze or run dry, hoping containment does not breach. This would work much like a wind turbine but work 100% of the time and yet has been over looked by all power companies though it has worked in the long past and with todays new materials technology would allow this to work today! K.I.S.S.
 
Sorry, no it isn't. Conservation of energy is the law.

This is a necropost and not useful, so thread locked.
