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.

probably not what [8th of 7] had in mind though. [kaz, Jun 28 2010]

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. |
