But it's as simple to build as a Bending Converter." "Jesus," said Mike the Angel softly. Lithium hydride. LiH. An atom of hydrogen to every atom of lithium. If a hydrogen nucleus is driven into the lithium nucleus with sufficient force, the results are simple: Li^ + H^ > 2He^ + energy An atom of lithium-7 plus an atom of hydrogen-1 yields two atoms of helium-4 and plenty of energy.
He could almost picture the stream of boron hydride blending with the oxidizer and flowing in an ever-increasing stream toward the combustion chamber. He heard the scrape as the instrument cable dropped away outside. Pegasus roared! And Rick knew. He knew that somehow he had failed, that the board showed green! Weight, One Ton Rick had no time to think. He reacted.
Titanium and oxygen, too hot to combine in most regions of the sun, join to form the vapor of titanium oxide, characterized in the sunspot spectrum by fluted bands, made up of hundreds of regularly spaced lines. Similarly magnesium and hydrogen combine as magnesium hydride and calcium and hydrogen form calcium hydride.
Horrified, Rick saw a fireman, clumsy in his protective suit, trip and fall before the oncoming flood of flaming boron hydride. Scotty moved, instinctively, his finely trained body responding with perfect co-ordination. Straight toward the oncoming flood he ran, into the edge of the flames, leaping the rapidly widening trench.
But all that heavy metal around the central reaction created all kinds of radioactive residues which had a tendency to scatter death for hundreds of miles around. Now, suppose a man had a pair of tweezers small enough to pick up a single molecule of lithium hydride and pinch the two nuclei together. Of course, the idea is ridiculous that is, the tweezer part is.
One gram of lithium hydride would give nearly fifty-eight kilowatt-hours of energy in one blast. A pound of the stuff would be the equivalent of nearly seven tons of TNT. In addition, it was a nice, clean bomb. Nothing but helium, radiation, and heat. In the early nineteen fifties, such a bomb had been constructed by surrounding the LiH with a fission bomb the so-called "implosion" technique.
John Gordon motioned to Dr. Albert Hiller, the Orion project officer. Hiller nodded. He spoke quietly, but not one of the hundreds watching missed a single word. "Apparently a fuel-pump bearing froze at the critical moment. With an unstable fuel like boron hydride, that made the difference. Internal pressure was too much for the shell to take."
Its composition is carbonic acid, 0.35; carbonic oxide, 0.26; illuminating hydrocarbons, 0.56; hydrogen, 4.79; marsh gas, C H , 89.65; ethyl hydride, C H , 4.39; specific gravity, 0.558. This analysis shows about 57 per cent. of carbon and 42 per cent. of hydrogen. If the well discharges one million cubic feet of gas daily, it would weigh about sixty tons, yielding thirty-nine tons of carbon. Mr.
He was enthralled by the activity in the blockhouse, and, careful to keep out of the way, he walked from station to station. Now and then he looked through the thick glass ports, and he saw the green mist of boron hydride as fuel throbbed slowly into the rocket's tanks. A thin, bald scientist in a scarlet sports shirt picked up a microphone and spoke into it.
He wondered if Snookums had discovered something that would be as much a disaster to the world economy as the Bending Converter had been. Fitzhugh got out his miniature flame thrower and puffed his pipe alight. "Snookums," he said, "has discovered a method of applying the pinch effect to lithium hydride. It's a batch reaction rather than a flow reaction such as the Bending Converter uses.
