"The thing that I'm most interested in at the moment is the so-called Infinite Energy solution - the possibility of finding new ways of tapping into virtually limitless sources of energy."
- Arthur C. Clarke

| Radar | ||
| Detection of objects at a distance. |
| A pulsating polarized ether wave, if directed on a metal object can be reflected in the same manner as a light-ray is reflected from a bright surface or from a mirror. The reflection factor, however, varies with different metals. Thus the reflection factor from silver is 1,000 units, the reflection from iron 645, alomagnesium 460, etc. If, therefore, a polarized wave generator were directed toward space, the waves would take a direction as shown in the diagram, provided the parabolic wave reflector was used as shown. By manipulating the entire apparatus like a searchlight, waves would be sent over a large area. Sooner or later these waves would strike a space flyer. A small part of the waves would strike the metal body of the flyer, and these waves would be reflected back to the sending apparatus. Here they would fall on the Actinoscope (see diagram), which records only reflected waves, not direct ones.
 (Radar diagram from Ralph 124c 41+ by Hugo Gernsback) From the actinoscope the reflection factor is then determined, which shows the kind of metal from which the reflection comes. From the intensity and the elapsed time of the reflected impulses, the distance between the earth and the flyer can then be accurately and quickly calculated. |

'...the rocket’s landing-arms automatically unfolded.'
'...points and patches of light... sliding all over their faces in a programmed manner that had been designed to foil facial recognition systems.'
'...the combined Wind-Suncatcher, like a spray of tulips mounted fanwise.'
'I went to the control room where the three other men were manipulating their mechanical men.'
'The low-slung monorail car, straddling its single track, bored through the shadows on a slowly rising course.'
'It was a smooth ovoid floating a few inches from the floor...'
'... he thrust in his charging arm to replenish his store of energy.'
'...the terrible Jovian gravity that made each movement an effort.'
