The metal-cylinder-tanks now in use are not streamlined. They are also too industrial-ish looking. A cluster of high pressure flexible hoses trailing out behind the diver from shoulders and back would offer less drag. The hoses could be different lengths to give a more organic look. The total volume
could be the same as the metal tanks.
Microbubble drag reduction

Cat SCUBA

Interesting idea, but very doubtful. Drag is directly related to surface area, and a cluster of hoses capable of holding the same volume of compressed air is likely to have many times the surface area of a single cylinder. [-] |

//too industrial-ish looking.// ... for what? Some sort of beauty contest? |
|
|
csea, I'm sure the surface area would be greater but the " form drag " would be less. lurch, When we watch movies of divers exploring tropical reefs there is such a rush of beauty it seems like the humans are all too underdressed for the venue. |
|
|
I claim no expertise in fluid dynamics - " form drag " was a new term for me, but it seems to occur at relatively high velocities. |

|
How fast does the average scuba diver travel? |
|
|
Maybe perforating the tentacles/hoses to let out a shroud of tiny bubbles would do the trick [link](?) |
|
|
//high pressure flexible// one or the other, not both. You could have small spheres perhaps... that would look organic'ish. [ ] |

I'd like to see a scuba tank for a horse - I'd imagine that they'd quite enjoy it. |
|
|
SCUBA tanks for cats ... hmmm. |

A link for you [8th of 7] |
|
|
Do divers actually travel fast enough for drag to
become a problem? Most of the time, when you
scuba dive, you are not in a hurry. |

Please link up described movie! |

Even if it is some hairy frenchmen with an undersized Speedo. OK, especially if it is a hairy frenchman with an undersized Speedo. |
