The individual transmitting fields and receptors are really simply matched-frequency units, each matching the electrical characteristics of some particular and unique beam of force. This beam is composed of Roeser's Rays, in their energy aspect. It took a long time to work out this tight-beam transmission of power, but it was fairly simple after they got it."
They apparently know nothing of the possibilities of cosmic radiation, but depend upon tight-beam transmission from their own power-plants which transmission they have perfected to a point far beyond anything reached by us of the three planets. They do not use accumulators, and therefore their dissipation is limited to their maximum reception, which is about seventy thousand kilofranks.
While Nadia brought in meat and vegetables and stored them away, Stevens attacked the problem of constructing the pair of tight-beam, auto-dirigible transmitter and receptor units which would connect his great turbo-alternator to the accumulators of their craft, wherever it might be in space.
Mike scrambled back to his communication board. He began feverishly to work the computer which in turn would swing the tight-beam transmitter to the target the computer worked out, He threw a switch and said sharply, "Calling Space Platform! Pelican One calling Space Platform! Come in, Space Platform!..." He paused. "Calling Space Platform...." Joe had a slide-rule going on another problem.
Microwaves from the ground played upon them radar used by friend and foe alike and the friendly radar guided tight-beam communicator waves to them with comforting assurance that their joint course and height and speed were exactly the calculated optimum. But they could not be seen at all.
But it pointed nose-down toward the Earth even as it continued to hurtle onward. The great steel hull and the small spaceship were 20 miles apart. An infinitesimal radar-bowl moved on the little ship. Tight-beam waves flickered invisibly between the two craft. The rockets raged toward them. The ship and the Platform were 10 miles apart.
