Ishikawajima-Harama Heavy Industries (Ltd.) has recently
shown a new large-screen display technology called Water-Vision.
From the photo in Business Tokyo for November, it appears to display
a color picture on a curtain of falling water. It's not clear how
this is done, but it seems to take a 3" water line to drive the
small-screen (20' by 20') version. The water apparently just pours
out on the ground. Picture quality is poor by TV standards.
A large-screen version (137' x 65') is available.
But how does it work?

Perhaps it is a projection tv kind of thing. Or perhaps they are using the sheet of water like a fiber-optic and injecting a raster line into it (with tounge in cheek) ...does the scan line get captured bye the water and moved down the screen? ?

Sure, and then the used scan lines are recovered from the pool below, for cleaning and re-use, by a special pump and filter system. This was required by the government before the product could be approved for sale, as there was major concern over the possibilities for long-term pixel pollution of the nation's water supply.

Lets see, I'm sure the EPA would have a problem with it, the question is how do you recover the isotopes of the various colors, or perhaps that is a DOE or DOD (DODO ?) question. Then again the FDA might get involved over the carcinogenic nature of red-pixels vs blue pixels-.... (ha) Seriously, I would like to know what is going on with it, and how it is done, though I could not resists the facicious (spelling ???) questions...! Cheers Woody
