dewdrop
designed glass stone for adhesion and flow control of fluids | |
Sort of a cross between scoria and a pipe to make pasta
shaped pebbles that control slow water seep.
Since the perfect shape is unknown. I like to start with a
pressed flat sphere, printed with tiny golf dimples. The
whole button is then twisted along a line of diameter,
like
those wooden
wind twists. The size of these objects
would
be about 15mm.
Obviously testing every shape under the sun would be
expensive and time consuming although artistically
pleasing.
A computation modelling program that allows the
sketching
of a the dewdrop and then scales up to give a couple of
truck loads with physical properties and possible seep
dynamics, would be the way to go.
CAD/CAM could be involved to take the design to the
recycled glass smelter's CAM.

I think you are asking for trials on various stone shapes. Well that's not an invention. You do the research, however silly and pointless, and come back and tell us which shape you want to invent. Thank you. |

I see no problem with proposal for a research program as a
halfbakery idea. In fact, I'd say a research proposal is the
quintessential half-baked idea. |

I know of at least two things *like* this idea.
One's used in chemical engineering -- ceramic rings (I
forget the eponym) dumped into a vertically-oriented
cylindrical tank, filling it up, but with interstitial space.
Fluids & gases are pumped into the tank at various points
along its long axis, and the rings encourage orderly
mixing.
The other's emplaced on the sea side of a seawall -- large,
irregular structures shaped like,if I recall, giant jacks, or
tank traps (sometimes, simply irregularly shaped boulders)
to break up and diffuse the force of a wave before it hits
the sea wall. |

So...hydrophylic and hydrophobic surfaces? |
|
| |
no, only scales of shape, to allow domains of the
fluid(probably water) to do their collective thing. |

i was thinking recycled glass because of the glut,
cheap and quite plastic when hot. Good for
automatically churning out truck loads. |
