Invention of Microwave Popcorn? (Mar, 1931)

The panel on the bottom left seems like a demonstration of making microwave popcorn. I have no idea what the ice was for. Perhaps to show that the popcorn wasn’t being heated?

Also, upper right panel, WTF? How does light make the apple move? Why does this involve a Rastus robot?

New Developments in Electricity

This powerful “Stroboglow light,” synchronized with the revolving fan blades, makes them appear as if standing still. Airplane props are studied similarly.

Above — Corn in the container between the two jars of ice was popped in two minutes by heat from high frequency radio waves directed at the kernels.

In reacting the historic William Tell scene, the apple on Rastus Robot’s head is knocked off by a ray of light from the photo electric flashlight in the head of the arrow.

Right — One of the numerous electrical devices invented by engineers to beautify milady’s complexion with ultra violet rays.

    that robot I remember seeing before, the bow and arrow had a flashlight in it and he had a photovoltaic sensor in his forehead that triggered a piston to pop the apple up. That with all the other things on this page were part of the “holy crap! we are doing things to stuff without wires directly connecting them!”

    Ol’ Rastus there is the granddaddy of the remote control.

    Wasn’t a piston http://www.paleofuture….

    Why Rastus? It was the 30′s.

    I don’t think they had reliable microwave oscillators in the 1930s and the caption says “heat from high frequency radio waves” which is not what microwave ovens do (they jiggle water molecules, which make them heat up). So I don’t know that it was microwave popcorn.

    I take it back. It could have been a form of dielectric heating like modern microwave ovens exhibit, although who knows what frequency they were using.

    Stephen: At least 27.12 or 13.56 MHz are reserved for diathermy machines. Looks like there’s a plates in the ice-jars, which likely are the actual capacitors, and the ice was just for cooling them.

    “Why does this involve a Rastus robot?”

    Well, why not involve a Rastus robot?

    And you may all mock, but doing stuff wirelessly was certainly new, different and exciting way back in 31 when many machines were burdened down with cumbersome wires and connectors.
