The Last Theorem - Arthur Charles Clarke [113]
“Actually,” Myra said, “that would be fun.” And Natasha said, “You bet!” And even Robert, hanging on to Natasha’s chair and listening to every word, bellowed something that Natasha explained was a yes. And so the family of four prepared for its first long trip together.
It wasn’t just Vorhulst’s invitation that made Ranjit look forward to visiting the Skyhook terminal. There were actually two reasons, and the first was the advisory board that Vorhulst had talked him into joining a number of years ago. It had been as undemanding as Vorhulst had promised—no meetings to go to, not even any voting on any issues, because if there were any issues troublesome enough to require a decision, that decision was made for them by the real controllers of the enterprise, the governments of China, Russia, and the United States. Ranjit had, however, been the recipient of a monthly progress report. There too the heavy hand of the big three was felt, because most of each report’s content was sternly secret, and even more of it was simply dismissed as what was cryptically called “development.” He had only been to the site a handful of times, and those visits had been quite cursory. Whether he would learn more by being at the scene Ranjit could not say, but he was anxious to find out.
The other reason was a surprise to Ranjit himself. The Subramanians didn’t have a car of their own—Ranjit and Myra biked to most places, sometimes with Natasha riding happily in front of them and Robert strapped into a child’s seat behind his father, and when they needed more in the way of transport, there were always cabs. But the university had promised the loan of a car for the trip, and Ranjit picked it up from the grinning Dr. Davoodbhoy. “It’s special for you,” he said. “Pax per Fidem sent it. It’s a new design from transparent Korea—with all those geniuses who used to build weapons now free for new civilian ideas, they’ve got a lot of stuff.” And when he’d explained what the perky little four-seater could do, it sent Ranjit back to Myra grinning with pleasure.
“Get me a pitcher of water,” he commanded as he pulled up at their house. Mystified, she obeyed. She was even more mystified when he ceremoniously opened the fuel tank and poured the water in, and when he then started the motor and listened pleasurably to its purr, she was totally baffled.
He gave her the explanation Davoodbhoy had given him. “Boron,” he said. “It’s called the Abu-Hamed drive, after I don’t know who, maybe the person who invented it. You know the element boron is so hungry for oxygen that it’ll pull it right out of compounds like water? And when you take the oxygen out of the water molecule, what do you have left?”
Myra frowned at him. “Hydrogen, but—”
Grinning, he touched a finger to her lips. “But boron’s terribly expensive, and burning a carbon fuel’s so much cheaper that nobody ever bothered with it. But here it is! They’ve found out how to regenerate the boron so they can use it over and over. And so we’re driving a car that not only is low-emission, it doesn’t emit anything at all!”
“But—” Myra began again. This time he stopped his wife’s lips with his own.
“Get Natasha and Robert, will you?” he coaxed. “And our baggage? And let’s see how this hydrogen burner works.”
Which turned out to be very well. They did have to stop twice to add water to the fuel tank, under the scandalized stares of the people running the filling stations they stopped at, but the little car performed as well as any fossil-fuel burner.
They were still ten kilometers from the terminal when Robert emitted one of his heart-stopping shrieks. Myra jammed on the brakes, but it wasn’t a sudden danger. It was simply an exciting sight. What Robert was waving at (as he said “Spider!” and “Climb fast!” and “Many, many, many!”) was the cable of the Skyhook itself, barely visible as something that glinted from the sun. But what it carried, once you knew what to look for, was visible enough. There were the cargo-carrying
