Talk:Eidophor

I'm 74, old enough to remember semi-technical articles about the Eidophor projectors; they were amazing devices. The arc lamps created so much heat that those barriers with slots between them needed water cooling. The article did not point out that the barrier slots (my term) were anything but focused on the screen; there were no "ghost" images of them at all, I'm virtually certain.

GE version
About 30 years ago, GE sold a commercial (not consumer) TV-projection system using at least some of the Eidophor principles. The article needs to reference this. WilliamSommerwerck (talk) 13:36, 10 June 2011 (UTC)

Loaned for Engelbart Demo
FYI Doug Engelbart's team at Stanford Research Institute borrowed an Eidophor projector from NASA Ames Research in Mt. View, CA for use in the Mother of All Demos in San Francisco to project the demo for a live audience of 1,000 or more - reference 1968 Demo Interactive under CREDITS / Others Giving Support he thanks NASA for the loan.
