Anti-Buoyancy Bubble Tube System GP version 1 and 2

Greetings All

I am publishing this paper under copyright. Feel free to use the information to build any device you wish. When it comes to commercial exploitation I reserve whatever rights are given to my by law.

Here is the design of the, Anti-buoyancy bubble tube system GP version 1 and version 2

These system use air bubbles to reduce the buoyancy of the descending side of a buoyancy type device for over unity. weighted floats are preferred.

Alan, hi!
Finally I can see a different/original underwater system!
This is clever and not hard to build.
I have another one also, but much more complicated.
Great, Alan! :)
Cheers! M.

Thanks

The best part of the bubble tube, it can be added to most buoyancy designs. You do have to have a geared blower to get enough air for the system.

Here is a closer drawing on this design, clarifying some of the details.

I will be working on the blower design to fit the needs of this system.

Alan, hi.

In the past I have done experiments with un-levelled communicating vases and I also arrived in ''bad dinamic floating'' water...

Of sure air insuflation was used, so as apeared recently on TV, with speculations about how would play ''bermudas triangle'' to sunk boats.

The practical conclusion I got is that best results will come if one use very small bubbles, but in large volume. Would be great if you could use some soap foam coming to surface.
There are quite good devices for air insuflation in fish acquaries.

As you know, main question will be the ''junction'' between water and air... so I think that the best shape can be the wheel... a curved duct seens better to avoid bubles scapes.
All the best!

Thanks for the thought and I have a very good way to make small bubbles. When in the vacuum cleaner business we had something call a foam applicator and it would work very well, I will also make sure to have soft water for hard water will not do as well.

Alan,
bingo! Great!
Some home detergent in the water, together to the blower, will enought.
Go for it!

I've given a lot of thought to bouyancy based systems, and I have decided they are all fundamentally flawed. I don't see how using bubbles can be any different. Ultimately, it's all about shifting the COG of mass - and whether that mass is solid, liquid or gas doesn't seem to make any difference.

Displacement, or what I call the 'price of insertion' will have to be the killer with any bouancy or anti-bouyancy system. It takes energy to blow bubbles under water, and any possible shifting in the COG of the system will demand payment, sooner or later.

Although bubbles are more convenient to engineer, the logic can't be any different from my system of inserting bouyant cylinders ('steel bubbles') into a tank of water.

Unless there was some flow of energy (heat, barometric pressure, whatever) into the system, I can't see this working ...

[murilo]

We are talking here about stuffs that may work and ask to be experimented.
The apparent density of a volume of water, with small bubbles generation is much smaller than pure water. No discussion!
What one will do with it is another question.
I have being very near to this idea in the past, and I'm angry with myself due to this.
I'm angry and at same time glad to give a hand to Alan.

Greetings greendoor

You (IMO) have to have blower, vacuum, and compressor experience to figure out how to get the bubbles needed. As a blacksmith I work with blowers. As once a vacuum cleaner service manager I know vacuums. I work with air tools and compressors as well. All and all I will have to build the blower system to use for the buoyancy lift as the primary force to run it.
As murilo has said small bubbles should work the best. The bad part is that it will be a few weeks before I can build it, due to a presentation of another invention that I have to make. I am looking (hoping) for a contract, and it looks like a better than average chance to get it.

PS-Bubbles would help your machine as well, but you may have to wait on mine so I can work or at least try to work out the bugs.

[murilo]

I'm sure about those small bubbles due to my experience.
The reason is that the counter turbulence sent by them is much smaller and the smaller relative density of water becomes more uniform.
Cheers!

One of my 1940's 'Parlor tricks;

Take a small shallow dish and place about 1/2" water in it. Carefully place a sewing needle or a piece of wire of similar size on the water. If placed carefully the surface tension will not be broke and the steel needle will actually float!

Now add one very small drop of dish detergent and the needle will sink as one would expect it to do in the first place.

To make minute and yet a high volume of bubbles, I suggest trying a piece of garden soaking hose, you can connect it to a standard hose fitting and cut it to any desired length and plug the open end.
