Hydraulic Rotary Actuator

I'm unclear as to the function of the actuators. Do they control the pitch?

How is the energy transferred? I don't see any connections.

Also unclear about any progress you may have made since September 2008?

'....Also unclear about any progress you may have made since September 2008?...'

.

If selling off the patent pending water portion of what is claimed occurred since 2008, I'd count that squarely in the progress corner, for the OP at least.

My reference was more to the lack of any change in the FB demo.

I was also not aware that ungranted patent applications were worth much.

More power to the OP.

I spent almost three years of my life and money trying to develope the turbine and get this into somebody's hands that could help me or just do it. Patent pending is actually pretty good. The patent alone cost $28,000 which I couldn't afford and sold the water intellectual property (IP) off to help pay for the patent attorneys.

Spending that amount of money was hard on both me and my girlfriend and it has not gotten us any benefit thus far. I'm still at a huge loss.

If I could just get paid for the amount of work and money I put into it so far, I would be happy.

It is not easy bringing anything to the market today and one of the reasons why the U.S. is in the horrible social and financial shape it is in.

I'm trying to get someone to help me develope a educational kit to try to get some creativity involved in the project. I have one interested party so far.

I don know what OP is. Please explain.

I can't get UTube here at work.

But,

$28,000.00 just to secure the patent......., I hope the majority is to get a prototype made.

I'm sure you have a very good idea, but if the majority is in attorney fees, for you to get you invested to get a Patent time and money out of it is difficult at best.

When I get home, I'll look at the video, don't get your hopes too high...........(that is one of the first things a patent attorney should say)

No sadly that was the entire costs of just the patent. Still looking for someone to help me fund the prototype. The material cost of the wind turbine itself is relatively cheap. What I don't have a handle on, is the costs to engineer and build the hydraulic actuators. I wanted to build one that had (3) 4' x 8' panels. The aluminum for all the framing was only $1,000 back in 2008. Obviously higher now and use standard sailcloth with UV protector as the panel material.

Once I build the prototype, sell it as a kit and allow people to do the labor themselves. I beleive it is the most cost efficient wind turbine system for home use you can get because of the low wind speed issue. The water turbine is a completely different set of issues since water currents are generally very stable in speeds. I'm starting to believe that www.HAEturbines.com may just be doing a stock pump and dump. Pretty dissapointing at their progress.

'...I was also not aware that ungranted patent applications were worth much....'

IMHO, that all depends on what the idea is. But broadly, the value of an idea protected by a well written provisional patent application or a submitted but not yet reviewed well written patent application, should only differ from the 'value as fully patented', by an amount equal to the 'value as fully patented' multiplied by the percent chance the patent will not be accepted, plus likely costs to complete the patent process, plus an amount for either the cost of funds until patent approval if commercialization is to be delayed until that point, or the an amount related to the risk of resulting from embarking of commercialization prior to patent approval.

If it is a valuable novel idea with strong chances of receiving useful patent protection, then a PPA might demand a price not far below what would be brought if already patented.

In any case, kudos to the OP (who now realizes to whom I am referring) for successfully monetizing the rights to one of their inventions.

I hope this all works out well for the OP.

The rotary actuator concept is meant to do a few things and it is difficult for me to explain how it works. I can however explain the results and you can see them in the video - http://www.youtube.com/watch?v=3NTbAz9GyHw I invision six total low pressure rotary actuators with each having a 90 degree rotation. Two actuators per panel that couple as hinges for the panels. As the flipping panel flips open and begins coming back against the wind, the torque from the flip coupled with the centrifugal force of the panel, is to great on the overall stability of the system so I needed to come up with a way to control and slow this down. Fortunately, the panel just in front of the flipping one is now finishing it's rotation agains the wind (leeward side) and is beginning to get into position to be the sail panel on windward side of the system. The hydraulic fluid would be forced to this panel, since it is the weakest one at this point in it's rotation, assisting it in getting into the best position, from a timing standpoint. This panel is draging behind it's structual arm because of centrifugal forces and is now assisted to get into position quicker. The 90 degree range would create the stops at the end of the flip and would stop it from actually hitting each panel's structural arm as they come back against them.
