Discussion Overview

The discussion revolves around the feasibility of generating electricity from ionized gas, specifically questioning whether it can be achieved without the use of a steam generator or external energy sources. Participants explore various concepts related to ionization and its potential applications in electricity generation.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants inquire whether electricity can be generated solely from ionized gas, questioning the definition of "original air gas."
  • One participant suggests that generating electricity directly from a stream of hot, ionized gas is possible, referencing Magnetohydrodynamics (MHD) as an experimental approach.
  • Concerns are raised about the environmental impact and toxicity of MHD technology, particularly regarding plasma conductor materials and ceramic insulators.
  • There is uncertainty among participants regarding the original poster's intent and clarity of the question about ionized gases.
  • A hypothetical scenario is proposed involving a chamber filled with ionized air and electrodes to facilitate electron flow, but questions arise about the energy required for ionization.
  • Some participants assert that there is a minimum energy requirement to ionize air, which cannot be minimized, and reference the second law of thermodynamics in their arguments.
  • One participant suggests that using electric power directly from a socket or battery would be more efficient than attempting to generate power from an ionizer.

Areas of Agreement / Disagreement

The discussion remains unresolved, with multiple competing views on the feasibility of generating electricity from ionized gas and the energy requirements involved. Participants express differing levels of understanding and clarity regarding the original question.

Contextual Notes

Participants highlight limitations related to the assumptions about energy requirements for ionization and the definitions of terms used in the discussion.

Can us generate electricity just from gas?
I meant not by steam generator but by ionize gas,for example from original air gas?

What is 'original air gas' in the context of ionized gasses?
 
How are you going to ionize the gas without using electricity?
 
This may be what you're after. You can generate electricity directly with a stream of hot, ionised gas. MHD is, afaik, only experimental but if the scale were big enough it could have legs.

Obviously going out with the rest of the "dirty" energy technology. It has its own toxicity with the plasma conductor material and the ceramic insulators.

Ignoring how good it may be for the planet, MHD satisfies the requirement of the OP.

I'm still uncertain what the OP was even asking about.

it certainly isn't very clear.

Imagine we have a chamber filled with ionize air,then there are electrode to attract electron and electrode as + ion collector so electron will flow from negative to positive generate electricity
But we don't need external energy to ionize the air

We don't? So where do these ionized air come from? And how much do you think there are in a standard volume of our air?

There is a minimum amount of energy required to ionize the air, and it is neither a small amount of energy nor is it something that can be reduced.

You really need to learn basic thermodynamics, especially the 2nd Law.

As of now, you're just making things up as you go along.

Thanks I will

And you'd get out of it some fraction of the power that the ioniser put into the system. Best use the electric power directly from the socket / battery that supplies the ioniser.
