Ocean Wave Machine by S.D.E. Energy Ltd.

S.D.E. Energy Ltd. is a Tel Aviv, Israel manufacturer and marketer of Sea Wave Power Plants - utilizing sea wave energy to produce electricity economically, and in an environmentally-friendly manner claiming that their system can generate electricity for 2 cents per kWh.

Basically, the buoys are placed on a breakwater and they move up and down, according to the frequency of sea waves. The buoys' movement press a hydraulic liquid, which is regulated by systems that convert the energy to circular systems that operate an electric generator.

The buoys, which make 10% of the system, are placed in the water, and the rest of the whole system, which makes 90%, is set on land with the option being located on up to 500 meters from sea shore. In the event of storms, the system is easily accessible for technical service. Additionlly, the buoys are neutralized and laid down on the jetty or the shore.

All of these wave machines are located on the surface. They are an eyesore that will deteriorate, and cause pollution.

I'm afraid I have to agree with yakakyak69.

@MsFishty This is a taxpayer money harvester.

Having worked offshore for many years now in a marine technical environment, I have to say that this device has too many moving parts, and is vulnerable to heavy seas. Survivability would in my opinion be very poor. The modeling may work quite well on a computer and test tank, but that's as far as it goes. Sorry!

[whotookmynickkokokai]

not a smooth device. I question about it survivability. How long will it last?

[juzzlookin]

You are advocating the use of air, which is compressible. This project is moving in the right direction, maybe the rams are slighlty small but definately the correct mechanics. All moving parts however should be booted, as even a small project will never be robust in that environment. I wonder if they are using the dropping motion to pump as well?

Sorry! I meant : almost nothing!

[jmvneto51]

How long it can handle the pounding of the ocean? Take a look on my projects! Nothing is in the water.

[paborralho]

Impressive! It goes up and down with tides?

[Aussiemoo]

yeah, why aren't more projects on a middling scale like this?
