I have devised a way to extract energy from wave action without moving parts in the salt water.
The principle is as follows:
A bottomless vessel is fixedly mounted in the sea with the top just above the highest one
waterline.
When the water rises, the pressure in the vessel rises.
The air pressure is discharged through a check valve.
Another inverted check valve ensures that air can enter the vessel again when the water (level) drops.
So through one valve air comes in and through the other valve the compressed air goes out.
Like a bicycle pump.
This compressed is discharged to a second vessel on the mainland.
So no electrical pipes in the salt water either.
The pressurized air in the second vessel is used to run a pneumatic motor.
This in turn drives a generator. And there is the energy.
Can this work or not?
Answer
In principle this can work, but I see going advantages.
You don’t have electrical lines in the water, but you do need a pipe to transport the pressure to land.
If you want to obtain a large pressure increase, the total volume of gas (including the volume in the tubes) must be small. This means: tubes with a thin diameter. But to force a volume of gas through a long tube with a small diameter, you need a large pressure difference between both sides of the tube. In other words, you lose pressure due to the viscosity, just like you lose electrical voltage due to the resistance of the cable.
