Environmentally Friendly Hydro-Generator

   @All,
What has come to mind is that what mscoffman linked to could be modified to a sinkable float. As such, it would be possible to have the blades enclosed to prevent killing off sea life.
If you like sea food like me, then that is something to be concerned about with over fishing and all.
When a float closes and sinks, it could operate 2 sets of blades, one on top and one on bottom. And when it expands, the blades could turn and keep powering the turbine/generator set up.
I will be able to post a drawing of some type on Monday. Have found out the local college has their library open on Sundays for a few hours. not sure if I can scan and upload there or not. But a drawing would help to better understand how it would work.
Also, by knowing a few values, then it might be possible to consider how much energy it could actually generate for what size. As the guy in Russia said, moving 10 tons creats a lot of power. The numbers I will aim towards are something practical like 2 100 lb. weights made from hydraulic cement. Water doesn't weaken it if the container wears.
Also, with they hydro side being enclosed, fresh water could be used which is easier on the blades.

edited to add; @All, I have let the company that furnished the blades for the people in Canada who are using tidal current. Their information states that if the velocity of water doubles then the power output is 8 times what it would be at the first velocity.
The reason for this is it would take a company who is interested in the specific technology to give any value to it. But will post it in here for discussion and who knows, maybe they will take part in it.
I do have experience with steam turbines and generators so will know some things in a conceptual drawing to watch for. Basically, I will be drawing (double intendre) on my experience working with things of this nature.
Might be Monday when I post.

p.s. If they like the idea enough to pursue it, I will ask that they remember Stefan who maintains this forum for us to have a place to discuss such things.

  @All,
I,m going to stick with Bessler.
With somethin like this, a tube changing it,s volume will either sink or float. When it,s moving in either direction would also move a blade assembly. This could possibly power a generator.
