“And that would do away entirely with generators,” added Joe triumphantly.
“Well, I wouldn’t say anything was impossible,” said Herb doubtfully. “But that seems to me like a pretty large order.”
“It is a large order,” agreed Bob, adding with conviction: “But it isn’t too large for radio to fill.”
“Speaking of lodging all apparatus in one fair-sized room,” Joe went on. “I don’t see why that can’t really be done in a few years. Why, they say that this new power vacuum tube which handles fifty K. W. is not any larger than a desk drawer.”
“I see the day of the vest-pocket radio set coming nearer and nearer, according to you fellows,” announced Herb. “Pretty soon we’ll be getting our apparatus so small we’ll need a microscope to see it.”
“Laugh if you want to,” said Bob. “But I bet in the next few years we’re going to see greater things done in radio than have been accomplished yet.”
“And that’s saying something!” exclaimed Joe, with a laugh.
“I guess,” said Jimmy thoughtfully, “that there have been more changes in a short time in radio than in any other science.”
“I should say so!” Herb took him up. “Look at telephone and telegraph and electric lighting systems. There have been changes in them, of course, but beside the rapid-fire changes of radio, they seem to have been standing still.”
“There haven’t been any changes to speak of in the electric lighting systems for the last fifteen years or more,” said Bob. “And the telephone has stayed just about the same, too.”
