[sci.electronics] One incredibly bright projector

thomas@mvac23.UUCP (Thomas Lapp) (09/20/89)

In the September issue of Information Center, a magazine related to computer
information centers, computer training and the like, there is (naturally)
a section devoted to new products.  There is a new Portable Overhead
Projector which is described as such:

"...the model 28A641 is a 17-pound projector that costs $380.  It is a 
one piece unit with handles, built-in non-skid elevation feed that
retract into the bottom, as well as a projector head that slides into
its own reinforced compartment.  The 14-inch projection lens and 
3360 Watt, 82V quartz Halogen lamp provide steady illumination."

3360 Watts, eh?!  Wow, what a heck of a light THAT would produce in the
conference room.  Maybe they could advertise that you can use it to 
project onto low-lying clouds as well!  Of course, it might be a little
hard to find the 41 Ampere circuit to plug it into ("excuse me, can I 
plug this little projector into your incoming mains?" :-).

Ah, well.  I got a pretty good laugh out of this little misprint (you mean
it's only 360 Watts?)

Wonder what kind of lens material they use that keeps the weight 
below 17 pounds, and will withstand the temperature from a 3Kw 
Halogen bulb? Them critters put out LOTS of IR.

Of course, it sells well in Gotham City, with the optional BatCaller
overlay...

Perhaps one of the Nuclear Reactor Backup Power units could be adapted 
to make the unit portable and self-contained? Hmmmm, might not even
need the bulb any more, what with the glow from the reactor......

Is 14 inches the diameter or the focal length?

I just read a for sale ad in our local system advertising a "20 cubic inch
refrigerator".
