Red October

[goku]

have you ever seen the movie The Hunt For Red October? the soviet sub had a hydro-dynamic drive system that allowed it to be extremly quiet. i have discovered some evidence that the hydro-dynamic drive may be possible :confused:

before i post my evidence i would like to see if anyone else has noticed the evidence.

hint: you may have seen it on television or you may have it in your home :naughty:

Hydrodynamic drives are already in use....are you thinking about something else perhaps?

a drive with no moving parts and consists of magnets?

maybe it was a hydro-magneto?

either way, it would work like a ionic breeze air filter, that's my evidence

[rockytriton]

so the magnets wouldn't move either?

[goku]

so the magnets wouldn't move either?

no

have you seen an ionic breeze commercial?

the sub drive would work the same way. positively charge in-coming water, then the water is pulled to a negatively charged grid.

[rockytriton]

The only thing I remember from the commercial is that dust is somehow magnetically attracted to those metal things, I don't remember anything about how the motor works or anything.

[goku]

no motor. the dust is positively charged so it is naturaly attracted to the negatively charged grid.

absolutely no moving parts.

[rockytriton]

well, I don't really know much about engine design, but wouldn't whatever that gets attracted to the negatively charged grid count as a moving part?

[goku]

:confused: no

[rockytriton]

ok, I guess I don't understand how this motor would actually do anything bug collect dust.

[goku]

that's what the ionic breeze is ment to do.

i'm talking about using the same technology to push a sub, quietly.

[rockytriton]

ok, but what is it going to do to push a sub? It would need to take in water and push water out, I don't see how it would do that.

[goku]

if you go to the following site it will explain how the air filter works.

if you click home & clean air, next click more info on the first filter, then select interactive demo, you'll see a video (commercial)

[goku]

i'm wondering what that joker would do if you stuck it in some water, hmm?

and if i had the money to buy one i'd do it.

completely silent propulsion, and what did we do with it?

made it into a air filter :confused:

[rockytriton]

well, I don't think that it is silent propulsion. I think that if you put it in water, it would sink.

Check out this link, the idea for ion propulsion has been around for some time now.

Don’t stick an Ionic Breeze in water! Part of it’s an air ionizer, which is a high-voltage electric gap, similar to the inards of a TV tube. I’m not sure it would be dangerous, but I’m pretty sure it would either trip an internal breaker, or a house wiring breaker!

 

The ”caterpillar drive” described in some detail in “The Hunt for Red October”, is a Magnetohydrodynamic drive, a real naval engineering concept that’s been prototyped in some surface vessels. It’s indeed proved very quiet, but inefficient, and difficult to get high power from. It’s basically a fixed stator linear electric motor where the “rotor” is made out of unconfined water. It’d work well in salt water, less well in fresh, and not at all in deionized water.

 

An Ionic Breeze works by ionizing air (freeing some electrons), then drawing it toward several negatively charged plates, to which big, slightly ionized particles, which can’t fully contact the plates, stick, while most of the gas gets its missing electrons back. You wipe the plates off every day or few days (depending on how much dust, etc there is in the air to collect. Though pricey, they clean very well, and draw only a dozen or so amps. They actually clean much better, though, if you circulate air past them using a well-place conventional fan – their “breeze” doesn’t appear strong enough to circulate all the air in a room. (I have one, and have tested it quite a bit using stick incense smoke).
