Generate Electricity from Atmospheric Pressure

Click For Summary

Discussion Overview

The discussion centers around the feasibility of generating electricity from atmospheric pressure, exploring various methods and concepts related to this idea. Participants consider both theoretical and practical approaches to harnessing atmospheric pressure for energy generation.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants suggest that electricity can be produced from atmospheric pressure differences, citing wind turbines as a common example.
  • One participant proposes a concept involving a vacuum container and a spring mechanism, where atmospheric pressure would cause a rod to move and generate energy.
  • Another participant challenges the vacuum-based idea, arguing that pressure alone cannot generate electricity without motion and that the proposed system would only work once without external energy input to reset it.
  • The importance of net movement of air and pressure differences in systems like wind turbines and energy towers is emphasized as crucial for energy generation.

Areas of Agreement / Disagreement

Participants express differing views on the viability of generating electricity solely from atmospheric pressure, with some supporting the idea and others contesting its feasibility, indicating that the discussion remains unresolved.

Contextual Notes

There are unresolved assumptions regarding the efficiency and practicality of the proposed methods, particularly the vacuum-based concept and the role of motion in energy generation.

We can produce electricity from atmospheric pressure difference

Wind turbines do this all the time :smile:

There is another interesting method to use this

i have an idea of generating electricity...
inside vacuum there is no opposite pressure.a vacuum container is taken with a lubricated end.the end is closed with a long and light weight rod.just below the rod on the bottom surface of the container,a spring is tightly paced .So, because of atmospheric the rod is sucked inside and the spring contracts and pushes the rod to its same position.then energy can be generated by the action of spring...

Pressure alone will not generate Electricity. To get energy, you need a force (or some pressure) and you need motion (or a flow of fluid).
Your suggested system would work for one shot only. You would then need to pull the rod out again (supplying your own energy) and start again. The atmosphere would only be acting like a spring, to store energy - and not acting as a source of energy.

The Energy Tower and, of course, wind turbines, work because there is a net movement of air, along with a pressure difference. A vital difference there.
