Nice one Alan.

And some things I have seen on the Mississippi river would scare the hell out of you. For instance a harbor tug sucked down into the river and the tug had no leaks or anything wrong with it. Just pure water movement.

People in Sydney are forbidden from swimming too close to the rear of ferries in case they drowned due to the air in the water in the form of bubbles. Plus, I remember on TV they tried to explain the sinking ships in the Bermuba Triangle due to the same effect? (bubbles/gasses) from the deep?

I think I remember watching it also on the "MythBusters" a while ago

good luck!

I posted this machine 5 days ago and I am still waiting for a rational explanation why the machine won’t work.

Greetings sevich

Not to many people pick up on my hints so fast. Very good

I was hoping to get Brian working before I told him this. Bubbles are the secret for a buoyancy device. But it is still tricky to make it work on its own. That is what my design is and it has the extra to do it. It is not expected to be as good as some of my other designs but it should still work. Brian's machine is over complicated.

I will post my device later on today, I have to get to work.

Brian,

Sorry for the delay.  My wife and daughter both have a fever and I'm not able to get to the internet as often as before.

I like your response to the explanation that your oringinal design would not be able to extend the bottom of the cyclinder due to the pressure of the water.  You reduced the surface area of the cylinder you wish to extend so that it did not exceed the force opposing it, right?  I did not see anything wrong with that!  Good job.  Keep in mind that you must be coupled to the vent tube during the expansion process so you do not increase the opposing force by decreasing the pressure inside your falling object.

But your original design required both sides of your cylinder (or cube in your new hypothetic re-design) to be able to expand.  So you must have expandable structures on both side to be able to push out, right?

With the weight in the middle of the two expandable structures you will not have 11 inches of stroke for the weight to fall through I think.

At the end of the fall you will need to abruptly stop the falling cylinder/cube/whatever, and then shift it to the side.  What mechanism is doing that?  Where does the energy for this/those actuators come from?

How are you coupling to a vent tube (internally pressurized below the surrounding water pressure)?  How much force with that take?  Where is that energy coming from?
