Hi. I would be grateful for the name of the generator company. I have been considering building a 1 metre diameter model and this may work quite well if I gear it up from the shaft.

@identernet Hi Paul. Sent you a response by email (since youTube doesn't allow URL's). For other readers, it's called the "Ampair UW100 Water Turbine". Max 100 Watts. I contacted the company once about their plans for a more powerful model - it was under development at the time. Cheers.

Thought you might be interested. Search SECAT wave energy device. I commented a while ago that I was following a similar track. Have decided to put my idea in the public domain. Unable to get any financial backing/grants. It must be who you know, not what you know.

@identernet Hi. I see a lot of potential for your system. Primarily environmental. It seems unlikely that your turbine would seriously damage any sea life. I like the simplicity of it too. I share your concern about fatigue. An efficiency of 28% for such a simple device might be quite cost effective. I can point out a company that makes a low-power, encased generate in an oil bath. You might use one to build a small prototype for a sea trial. Re financing - I must not know the same people.

@identernet My preferred embodiment does not use a Wells turbine. My preferred embodiment utilizes articulating blades that adjust their angle of attack in response to changes in water speed and/or direction. However, the scope of my patent application includes all wave-driven venturi-type designs which use any kind of turbine. You can contact me directly for a more detailed discussion. moffatbrian@gmail.com

@moffatbrian Hi

I assumed that would be the case. The reason I ask is that I have been working on a very similar idea to yours, but use my own turbine design. This is a unidirectional turbine which is not based on the Well's turbine principal, and as far as I know unique. As the one you use is a proprietary turbine brand, could you confirm that it works on the Well's principal. The reason I ask is that I don,t want to waste time on my design if it has already been done.

@identernet Hi. Sorry for the delay in my response. Due to the rotational inertia of the shaft and turbine, reversing direction every 4 seconds would likely be problematic. Therefore, we use a "Wells" type turbine, i.e. it's bi-directional. That is, the turbine keeps spinning in the same direction regardless of the direction of water flow. We actually use a proprietary bi-directional turbine design. Thanks for the question.

Hi

Like your idea but am I right in believing the turbine rotation changes direction twice per wavelength, or do you use a "Wells" type turbine. I always believed this would cause problems, but not being an electrician, there may be a simple solution for this. Anyhow good luck.
