"The whole problem of energy sources is going to be solved by little solutions, not by some big new piece of technology that does everything. We got into this crisis by believing that we had one big piece of technology that would do everything (oil)."
- Gregory Benford

Telesolidograph  
  Projects three-dimensional images at great distances.  

The Hierarchy’s solidograph is a three-dimensional motion picture. The telesolidograph is the same sort of thing, except that the primary multiple-beam is invisible, long-range, and highly penetrating, only erupting into a visible, three-dimensional image when it reaches the focus. Slightly analogous to a needlepoint spray. So, for instance, if we want bare feet scampering around, or what not, we just fake a solidograph of them and feed the tapes into the projector. Phantoms to order! Vocal manifestations work in about the same way.

“The instrument I used is a bit more complicated, of course. Two-way. Viewer and projector. So I’d have a miniature image of the general focal region to guide me in operating my lifesize phantoms and manipulating the remote controls of the house.

Technovelgy from Gather, Darkness!, by Fritz Leiber.
Published by Astounding Science Fiction in 1943

It is possible to use interference techniques to dissolve such phantoms: see the entry on the Polyfrequency Neutralizer.

Compare to the solido projector from Dune (1965) by Frank Herbert.
