1. How do platelets work in blood clotting?
2. What could easily manufacture gigantic platelet-like items from easily available waste (perhaps PET bottles?)
3. How effective would artificial macro-platelets be in temporarily patching the dam, in circumstances such as the recent New Orleans
in America situation, or any situation where for example, a river needs to be 'turned off' or diverted from an unwanted course until a more permanent construction can be arranged.

Supposed to work like platelets. [reensure, Sep 06 2005]

Give me an idea, please...Mr. Tindale, I am very disappointed in you. |
|
| |
P.S. Blood coagulates on contact with the air. I don't think the analogy works for a river. |
|
| |
Thicken the water by the addition of self adherent / reactive lumps, impede its flow - I can see the idea here. Nifty. |
|
| |
Would it be possible to seed the water with grains that activated on being turbulated, perhaps becoming more and more adhesive? |
|
| |
I'm assuming that there is a minimal amount of turbulance in a naturally flowing river, and water coursing over a levee might be bashed about. |
|
| |
Surely a giant sponge would be more appropriate. (Natural sponge, naturally.) |
|
| |
It might be that the 'platelets' would have
to be the size of dustbin lids. |
|
| |
More like actual plates then, in many ways? |
|
| |
Yep. They'd have to have aspects of their
shape or form that caused them to 'catch'
each other, as a strong tendency. They'd
also have to have some means of catching
each other in pretty much any degree of
overlap, that tries to prevent liquid flowing
between them. Now, does this mean they
have to be absolutely watertight, or just
have a tendency to cause flow to go round
or over, rather than through? |
|
| |
So, the next time huge walls of water come rushing down the street, you want plates inside, just in case the existing debris is not decapitating enough people? |
|
| |
How about metal trash can lids? Then just bring in giant electromagnets on either side of the break. |
|

The only problem is to entice a few to stick solidly to the solid bottom and thereby serve as a foundation for further accretion. Others suggested air dropping tons of debris into the watercourse, likely to cause collateral damage or to liquefy an already weak and waterlogged earthwork wall. Still others suggest airdropping pylons to embed deeply into firmament and serve as anchors, likely to cause not only the aforementioned damage but also possibly sever underground utilities to tactical facilities or isolated areas. |

What about "Barsleaks"... I think that's what it's called.. The stuff you put in your car radiator to fix it (unless you use egg) -link |
|

reensure, - aha. I don't think I read your
idea (or if I did, didn't see it for what this
is). This is therefore redundant, if yours is
this too. |
