Can Sound Waves Be Used as a Renewable Energy Source?

Click For Summary

Discussion Overview

The discussion explores the potential of using sound waves and other unconventional methods as renewable energy sources. Participants propose various ideas, including harnessing sound from mines and waterfalls, utilizing volcanic steam, and innovative concepts involving materials and biological organisms.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • Some participants propose using sound waves from mines and waterfalls as an energy source, suggesting the installation of membranes to capture energy without harming aquatic life.
  • Others argue that sound energy densities are extremely low, making it impractical to harness significant energy from sound waves, even in high-energy environments like waterfalls.
  • A participant suggests the idea of using pendulums at the poles but is challenged to provide a practical application for this concept.
  • Another participant emphasizes the importance of considering the cost-effectiveness and energy output of proposed energy systems, questioning the viability of systems that take too long to pay for themselves.
  • Creative ideas are shared, such as using a sponge to absorb vapor above the sea surface for agricultural purposes, though some participants express skepticism about the scientific feasibility of these concepts.
  • There are discussions about the potential effects of magnetic or electrostatic fields on materials, suggesting applications in construction and aerospace.
  • One participant encourages another to focus their creativity with a better understanding of physics to enhance the practicality of their ideas.

Areas of Agreement / Disagreement

Participants express a range of ideas and creativity, but there is no consensus on the feasibility of the proposed energy sources. Disagreement exists regarding the practicality of harnessing sound energy and the scientific validity of some creative suggestions.

Contextual Notes

Some ideas presented lack detailed explanations of how they would function as energy sources, and there are unresolved questions about the cost-effectiveness and energy output of the proposed systems.

Who May Find This Useful

Individuals interested in renewable energy concepts, innovative engineering solutions, and the intersection of creativity and scientific principles may find this discussion engaging.

What about using soundwaves from mines and waterfalls as an energysource?

you could put a membrane in the exit of the mine, or over a waterfall. Then we would get energy without killing the fish!

How about periodically fill a volcano with saltwater and use the steam as an energysource like with a geiser and as a sweat water resource at the same time!

One problem: sound energy densities are extrordinarily low. Tiny fractions of a watt per square meter.

Even around waterfalls?

Yes, even around waterfalls...even around airports. sound waves carry pretty much no energy worth attempting to harness. If they did, even moderately loud noises would destroy our eardrums.
 
Pendulumns at the poles following the magnetic pole?

Instead of just blindly throwing out ideas, how about suggesting (a) how you would use them as an energy source, and (b) what you would use the energy for.
 
Sariaht, in any event you certainly possesses creativity, and somewhat responsibily structured at that(as oppossed to seriously off-the-wall theorist we hear from time-to-time) I love it!
In neither of your posts here have you claimed anything like "free-energy" rather you are searching for natural, unused sources of energy to be utilized. Excellent.
With that endeavor, also focus on whether or not the cost of establishing a particular energy extraction system and the actual energy produced is financially attractive. This doesn't mean that the system has to immediately start paying for itself. No! What system does?!
But it does have to be reasonable with regards to time. That is, if a certain system pays for itself in, say, 3-7 years, than I would say that it is a viable technology.
It also has to be reasonable with regards to power produced.
If a system pays for itself in 5-years yet only produces, say, 10-watts of electricity, is it REALLY worth the effort?
Keep these things in mind, and certainly keep your creativity.
 
Thank you very much!


What about putting a black spunge (made from oil) above the sea surface near the equator and let it absorb the vapour, so that you can through sand on top and grow vegetables and stuff on it? The spunge could float on an iron fence held up by a giant plastic ring. And stay put with an iron chane connected to the seabottom and to a generator that uses the wave-energy to warm the water underneath the ring.

You're like my 4 year old nephew. Has an active imagination...but no real sense of scientific concepts.

That's funny

A boy sneaking around looking at other peoples theories "just for fun" is what you are neutroncount.

How about giving a plate inside the drills in the mines a charge so that the magnetic field change the frequencies inside the mountain to frequencies helping in the drilling?

Some materials get's harder in magnetic or electrostatic fields!

This could be used in skyscrapers etc, as a protection against fow.

Or in spaceships.

Another way to interpret neutroncount's message is that if you would learn some physics it would greatly focus your creativity and make it much more likely for you to actually do something useful. Creativity is a wonderful thing, but on its own its just taking shots in the dark.

Thank you Russ.

It's not like I'm stalking you Sariaht. But when I read your threads or comments, sometimes I'm perplexed by their seemingly random direction and interesting logic processes.

Thank you neutroncount.

And Russ, I'll try.

By the way. How about giving bluegreen bacterias a communication gene?
We could try and make a such. Maybe they would develop consciousness?
