AI Thread Summary
Generating electricity from gas, specifically through ionization, raises questions about the feasibility of using methods like magnetohydrodynamics (MHD). While MHD could theoretically generate electricity from ionized gas, it remains largely experimental and has environmental concerns due to toxic materials involved. The discussion highlights the misconception that air can be ionized without external energy, emphasizing that a significant energy input is necessary for ionization. The practicality of creating a low-energy ionizer is debated, with experts pointing out that the energy required to ionize air cannot be minimized effectively. Overall, the conversation underscores the complexities and limitations of generating electricity directly from ionized gases.

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.
 
This patent for an MHD disk is over 30 years old...

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.
