"Water Body Oscillation" Power

[Oxygon]

I could have swore that I shared this idea here, but couldn't find it...

So here is its basic idea...

You have a Wall/Door-like structures (net/etc) anchored near a beach and utilize the incredible power of many "cubic tons" of oscillating water to generate power via a back and forth motion...

Also another way to get the energy could be a universal axis along the hinges on many Wall/Door-like structures...

I got this idea a few years back while watching a show on "animal planet" where they were video taping a grouping of fish swim forward thru the water while also moving back and forth... I thought about how much raw power that much water would be applied to a device like the one I just described...

Anyway please post a responce...

thanx...

Interesting idea.

[Oxygon]

I think soo...

Especially since it doesn't pollute in any way and except for some potential "aquatic disturbance" (which could be allieviated by netting off certain portions of beach for a "Wave-Farm") I cant think of a draw back...

It won't affect the eco-system really... And the payback for initial investment is sure...

the water will oscillate and the power will be generated...

I don't think that wave oscillation stops really?... at least "I think" its more reliable than wind energy...

[Fletcher]

Nice idea. You could attach a simple crank like a peddle car action !?

[Oxygon]

Yes, I thought a "rachet-like idea" would allow the force of the overall wall to be applied simultaniously along the cable/conduit/axial lines "thingy"... :)

Because the wave oscillations come in at various times and would apply their forces at different times if not for a ratcheting device... although a racheting device would limit the power recovered from the waves to a one-way rotaion... I suppose two conduits/axial lines could get both back and forth motion out of the process...

I've seen this before, I'm guessing it was Lightwave that posted a link to a site with a device like this? It had two paddles connected to a crank shaft, 90 degrees out of phase (I assume you place the paddles so that the waves hit them 90 degrees out of phase, you'd need to know the average wavelength for that).
EDIT
Nope, not lightwave. I don't know what thread it was in, it's somewhere on this board though.

You can anchor a float and the waves lift it. That gets your machinery out of the sand on the beach. Curved reflectors have been proposed to concentrate reflected waves as well.

Hi Oxygon,

Wave generators have been discussed as possible energy sources for decades. Why no one has acted upon it though, who knows. I had a junior high school teacher imply it was because of the oil industry, so it's been quite a while. You should do a web search on it, and see what if anything comes up.

OK, lets get something straight...

this is not a wave power device...

this is a "wave oscillation" device... or "water body oscillation".

Sorry for the improper definition...

This device utilizes the "water body oscillations" of up three feet plus during oscillation, during this motion the bottom hung "doors" which "at rest" stand vertical... wave back and forth becuase of the "panel/flat surface" dividing the "water body" and uses this massive movement of water to convert this "back and forth motion" into electricity...

Other than the wave floats I have seen out there on the internet, this idea utilizes a much greater force and a much greater motion... than "up and down" as waves come in or pass by...

it is much better...

[Kirk]

The energy of the water running up the beach came from the wave. If you extract the energy from the wave your "oscillation" will cease -- or are you talking about diurnal changes?

Kirk

[Oxygon]

Well it isn't diurnal in nature...

Listen here is axactly what I saw... and how I got the idea...

A ship was about 300ft of shore in a shallow water area, maybe "7ft" down to the sand (this is a flat area) and they shot the camera straight down onto a grouping of fish swimming forward "in the water", the water they were in was oscillationg about three to five feet back and forth...

the power here is the total movement of the "water mass" moving back and forth....

the panels attached to the sea floor acts to "catch" the massive movement of water that oscillates off-shore...

Not the waves near shore or out at sea...

listen, it would be a great difficulty to resist the movement of a massive wall of water... a large bottom hinged panel takes that "back and forth" motion and can turn it into electrical energy... via various tech.

[MrTim]

I think what Oxygon is trying to say is that:
If you have a swimming pool with the panels in it, and somebody does a cannonball into the pool (or otherwise gets the water to slosh around), the motion of the water will move the panels (which are attached to the generators.)
It doesn't use tidal energy, just water motion.
Is that about right?

[jim_mich]

As I said before, I think your idea is very interesting. Just look at any beach as the breakers roll in. Then look at how far each wave moves up the beach and then flows back. That is the approximate amount of water that is sloshing back and forth beneath the surface a little ways out. It may only move a few feet, but the shear volume of water breaking on a beach is enormous.

One problem is when the sea become calm it quits producing. The solution is to have the device pump water up into shore basins and use conventional turbines as the water returns to the sea. And who knows it might prevent coastal erosion?

thats about it... simplified.

Thats what I thought...

Or both... Maybe we could still use whats left during the pumping to generate energy too... if there is enough energy left.

It may only move a few feet, but the shear volume of water breaking on a beach is enormous.

I imagine a long panel would have tremondous power...

Kirk

Doesn't matter where you extract the energy. It is in the wave.
