Senator Ford. Of course, I understand there will be a lot of change— in fact every day. We are experiencing that now. You mentioned the idea of using large mirrors in space to reflect sunlight to earth, to illuminate the night in some areas. I understand vou are from Arizona—and I wish Senator Goldwater was here. He may not mind those mirrors shining on Arizona, but I hope you will keep those mirrors away from Kentucky. I would like to have a little night and not work 24 hours a day. It seems to me that that would create a lot or problems for people, to say nothing of animals and plants and so forth that God created, especially the dav and night. Mr. Stine. This is true. However, there are some areas of the Earth—say, for example, areas of the Great Plains or the rice belts of Southeast Asia that are really quite prolific when it comes to growing food----- Senator Ford. And people. Mr. Stine. And people, unfortunately, yes—where this concept of Krafft Ehricke's of “Lunetta,” just simply providing enough radiant energy to accelerate the g"owing process—-we might eventually have to come to that. Because I don't think we are going to be able to move our agricultural industry into space for quite a while yet. I don't think we have the technology for that. Senator Ford. You stated that by the year 2000, I think, that we would be pouring 51.8—or something like that—quadrillion Btu's up the stack as thermal pollution. But why is this bad and what will the consequences be? Mr. Stine. The consequences can be many—and I think this is one of the things that the environmentalists are worried about: The raising of the temperature of our streams, of our oceans, of our atmosphere—creating heat domes over the cities and industrial areas. I have had time to work this out. I don't think it would make major change in the earth's climate—-but we don't know, we just don't know that much about climate yet. Senator Ford. In your testimony, I believe, while stating that the use of a microwave transmission system is technically feasible, I think you said—you seemed to suggest that maybe we should look at other alternatives. What faults do vou find with the microwave transmission? Mr. Stine. I don't know whether I could say that I find fault with it, sir. I just think that we should be looking at several of them so that we have some options. The microwave relay system may seem to be quite feasible todav. Later on, in the further development of this, we may run into a “glitch.” It may turn out that it is not the redhot thing we thought it was in 1976. Senator Ford. You are not saying we should not pursue it, though, are you? Mr. Stine. No, sir. I am not saying we should not pursue it. I think we are in a situation where we have got to pursue every possible energy resource we have got. Senator Ford. In vour book that you have referred to several times, I think you stated that the planetoid belt is waiting a future Andrew Carnegie.
