Wave Compressor
Scroll Down there's lots of good information here. Click on the Picture too.


  Most of the “wave energy converters” I’ve seen have one thing in common: They are designed to make money. They are not made for the Do It Yourself, for a very-little-money type of process.

This illustration shows a simple, DIY way of capturing wave energy that can be made of inexpensive Natural Fiber Reinforced Concrete.

The sizes will vary depending on your conditions and uses.

While it’s claimed that wave energy has the greatest energy density of any alternative energy, that is measured by the square foot, and it may be expensive to make something large enough to generate electricity. Try it and see.

The illustration shows a simple way to compress air from wave power. The process does not need lubrication, so if you use it for surface-provided air, you can breath underwater longer than with air tanks, and without breathing petroleum fumes. You will need to get an air control valve, a mouth piece, a breathing hose, and maybe a pressure-relief valve which are available commercially. Then you can swim under your island, inspect it, and add buoyancy when needed.

You can add a simple hose, with a manual valve on the end to blow up further Plastic Trash Bag Floats right there under your island.

When you’re not swimming, you can hook the air hose (with the right connecters,) to any pneumatic device you wish, even to a small turbine for generating electricity.

The purpose of the air storage tank, is to accumulate compressed air between waves.

Through condensation, the air tank may gather water, that can be removed now and then with a manual “drainage valve” in the bottom.

A simple one-way check valve, called a “duck bill” can be made of silicone rubber window sealant as shone in the 2nd illustration.

The polyethylene form is removed after the check valve is dry. The Silicone Rubber is used to make the duck bill and to stick it to the CPVC coupling. Then the CPVC coupling can be connected in the regular fashion.

Or you can buy commercial check valves.

This design is both inexpensive, and very functional. Since tidal waves are just large, slow waves, this design is good for tidal generation as well. The trick is that the main column should be tall enough to be above high tides and high waves, and the lower opening must always remain underwater at low tide in the trough of the ordinary waves. That way it will capture energy from both types.

The output is compressed air, the amount of compression will depend both on the strength of the waves, and the size of the installation.

There are many ways of turning compressed air into electricity. There are the common popular methods, pumping of water to run a jet turbine as I have shown, the high efficiency types with no moving parts and so on. The trick is to produce electricity that is in sync with the local power company, so you can sell it. And one way of doing that is to use an AC motor, driven faster than it operates as an ordinary motor. It then becomes a synchronous alternator (generator.)
