Hi,
My name is Claudio Bianco. I am an inventor, and have just completed my last work called "Continual Wind-Up", with which I take advantage of water oscillations to wind up a cord, and thus generate electricity.
I believe to have opened a new research field for renewable energy, but since I am the father of this invention, my opinion does not matter.
I chose to use internet to make the invention known and I would appreciate your opinion.I would therefore like to invite you to discover a
new way of generating electricity without polluting on www.cuerdacontinua.com

I think that there is promise in this. I remember seeing a similar invention about 10-15 years ago. This one had a float on the surface of the ocean that moved up and down with wave action. attched to it was a long pole that went down to a piston inside a cylinder with a check valve at each end. That would pump water as the float moved the piston up and down. this pumped water woudl be forced through a turbine to generate electricity. The prototypes reportedly worked quite well. I haven't heard anything about them since though. I believe it was in popular mechanics or somethign like that.

I've also seen papers describing similar items to what Bill is talking about. The problem with all these things that I've read about is they work great in a lab, and even sometimes okay in short-term tests in the ocean. But, over time they just can't stand up to the wind and wave action and break down. The duty-cycle is just too short over the long-term.

I started looking around, and found many inventions that harvest energy from wave action. Most of the turn it into electricity, or pump water ashore somehow. A few even pumped water ashore to be run through hydroelectric generators. Why is your invention storing up energy in a spring? What will the spring then do?

I would agree that there is a tremendous amount of energy in both waves and tides that we have not effectively captured.

If you take your watch analogy, and extend it to a Grandfather clock. You have some pretty hefty weights to lift every couple of days.

Now... most of these are being replaced by clocks that will run a year or so on a single AA battery, and you'll realize how little power is actually being used to turn the clock hands. Although, undoubtedly the grandfather clock isn't very energy efficient.

I would agree with what others have said that you have to deal with some pretty harsh environments, salt, water, organic life, etc. But, on the other hand, we have ships, propellers, locks, and etc that run in that environment for decades (usually requiring periodic cleaning).

Now, back to the watch analogy.

An interesting watch might be the "self-winding" watch.

I.E.
You might be able to create a fully sealed oscillator unit. For example, put your oscillator on a pivot with an internal ball or weight that would move with the wave (or tide) action.

You would still need some kind of a pivot or something... but that could even be pretty crude such as a steel chain.

Best of Luck,

BTW:
I would eliminate your section on the "Perpetual Mobile" and "Perpetual Mobile in Space" if you wish to be taken seriously by anybody in the scientific community.

I kind of got lost in your design.

Anyway, the whole design should be able to be reduced to a piston below a column of water.
And, the energy to raise the column of water with the piston (say driven by compressed air).

And, the energy realized by letting the piston return to its previous state.

The two, of course, would be equal, minus energy wasted with friction and etc.

Anyway, build and test it before you actually patent and publish it.
