Generating Electricity from Gas: Is It Possible?

In summary, the OP was asking whether or not we can generate electricity just from gas. I believe that we can, but it would require using low-energy methods.

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.
 

1. Can gas be used as a source of electricity?

Yes, gas can be used as a source of electricity through the process of combustion. When gas is burned, it produces heat which can be used to generate electricity in a power plant.

2. How is electricity generated from gas?

Electricity is generated from gas through the use of a gas turbine or a gas-fired engine. In both cases, the gas is burned to produce hot gases which then turn a turbine or engine, generating electricity.

3. Is generating electricity from gas environmentally friendly?

Generating electricity from gas can be considered more environmentally friendly than traditional fossil fuels such as coal. However, it still produces carbon emissions and contributes to climate change. Alternative energy sources, such as renewable energy, are considered more environmentally friendly.

4. What are the advantages of generating electricity from gas?

There are several advantages to generating electricity from gas. It is a relatively clean and efficient process, producing less carbon emissions compared to other fossil fuels. It also has a lower cost of production and is readily available in many parts of the world.

5. Are there any disadvantages to generating electricity from gas?

One of the main disadvantages of generating electricity from gas is its contribution to climate change. It also requires the extraction and transportation of natural gas, which can have negative environmental impacts. In addition, the price of gas can fluctuate, making it less reliable as a long-term energy source.
