PROMETHEUS also has the required chemical inertness to- ward the coolant, which will be mercury or some other low-melting metal. There will be some unavoidable reaction of the shell wall with unreacted hydrogen or deuterium as well as nuclear reaction of the shell material by neutron capture. In the case of carbon these products will be gases at the reaction temperature and can be efficiently removed. Finally, graphite brick is cheap. “We have devoted a good deal of calcu- Jation to the probable dimensions of the sphere. Assuming that the ion beams and energy flux can be focused within a space of one cubic centimeier, the reaciion sphere wili be no greater than five meters in radius for the AHGT process run ai three thousand degrees wall temperature. A two-meter radius would probably work but I think we should adopt the larger figure in our first model to give us an efficiency factor to play around with. If we intend to use ordinary hydrogen, the sphere will need a radius five times greater, but I would be inclined to build the smaller model first.” Brennan sipped his drink and thought. He said nothing for a long while. Finally he shook his head as if to clear it of an unpleasant thought. | “Td like to congratulate you for the ingenuity of your solar furnace,” he said at last. “I assume it will work. You’re the expert in the field, after all. But if you assume that. your invention will put new ideas into the heads of the yokels and tease them out of their Trees, you’re most sadly mistaken. A solar furnace four yards across; practically a package unit! That’s what the bushmen have been screaming for! Up to now they’ve been starving for energy in their hollow trees. Now theyre going to get it in little magic bubbles. small, cheap, inexhaustible and practically eternal!” Daniel protested: “AIl right, that can be the lure. But once they swallow it, they’]l have to accept the need of an in- dustry to build and maintain them and a science to develop and perfect them!” “Why? Aimost everything you’ve de- scribed could be built by a good machinist! When I came here I was afraid that I would have to listen to some impossible idea. It’s the other way around. Your star is little enough to hide in the woods and simple enough to be handled by country mechanics.
