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
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

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?

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]

no

[rockytriton]

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