"We are not allowed telephone communications with our friends and families," replied Hilda, "only outgoing letters, which are heavily censored."
"Five years is a long time to be away from your loved ones. Why didn't you obstruct the research by slowdowns and sabotage?"
Hilda shook her head solemnly. "Because they threatened a horrible death to anyone who hampered the research."
"And the lives of our families back home as well," added Claus. "We had no choice but to put forth a dedicated effort. We also had a true desire to continue our life's work, to create a clean and efficient energy source for the people of the world."
"One man who had no family was made an example," said Hilda. "They tortured him by night and forced him to work by day. He was found one morning hanging from the light fixture in his room. W
e all knew he was murdered."
"You believe he was murdered on orders from Odyssey officials?"
"Executed," Lowenhardt corrected him. He smiled grimly and pointed up at the ceiling. "Look for yourself, Mr. Pitt. Would that fixture, which is little more than a wire and lightbulb, support the weight of a man?"
"I see your point," Pitt acknowledged.
"We do what we're told to do," said Hilda quietly, "whatever it takes to prevent harm from coming to our son and two daughters and five grandchildren. The others are in the same boat."
"Have you and your fellow scientists made any progress in developing fuel cell technology?" asked Pitt.
Hilda and Claus turned and faced each other with quizzical expressions. Then Claus said, "Hasn't the world learned of our success?"
"Success?"
"Along with our fellow scientists, we have developed an energy-generating source that combines nitrogen-producing ammonia and oxygen out of the atmosphere to create substantial amounts of electricity at a very low cost per unit, with pure water as its only waste product."
"I thought practical and efficient fuel cells were decades away," said Giordino.
"Fuel cells using hydrogen and oxygen to produce electricity, yes. Oxygen can come from the air. However, hydrogen is not readily available and must be stored as a fuel. But because of our fortunate and almost miraculous breakthrough, we have paved the way to nonpolluting energy that is available to millions of people as we speak."
"You talk as if it is already in production," said Giordino.
"It was perfected and tested with great success over a year ago." Lowenhardt gave him the look of a man staring at a village idiot. "Production began immediately after it was perfected. Surely you're familiar with it."
They could read the expression of bafflement and incomprehension on Pitt's and Giordino's faces as genuine. "That's news to us," said Pitt skeptically. "I'm not aware of a new miracle energy product sitting on store shelves or powering automobiles."
"Nor I," Giordino chimed in.
"We don't understand. We were told that millions of units had already been produced by a manufacturing facility in China."
"Sorry to disappoint you, but your great achievement is still a secret," Pitt said sympathetically. "I can only guess that the Chinese are stockpiling your creation for some inexplicable purpose."
"But what do they have to do with the tunnels?" Giordino muttered, confused at trying to put two and two together.
Pitt sat down in a chair and stared thoughtfully at the design in a throw rug. Finally, he looked up. "The admiral said that Yaeger's computer concluded that the purpose behind the tunnels was to lower the temperature of the Gulf Stream and throw the eastern United States and Europe into eight months of frigid weather." Then he turned to the Lowenhardts. "Your cutting-edge power technology, is it designed for automobiles?"
"Not at the moment. But eventually, with more study and refinement, it will generate enough clean energy to power all vehicles, including aircraft and trains. We've gone beyond the design stage. Currently, we're working out the final phase of engineering before running tests."
"What does the gadget in production accomplish?" asked Pitt.
Claus winced at the word gadget. "The Macha is a self-sustaining generator that can provide cost-efficient electrical energy to every home, office, workplace and school in the world. It makes air pollution a nightmare of the past. Now a family home, no matter how large or small, located in the city or in the farthest reaches of the country, can have its own independent source of energy--"
"You call it the Macha?"
"Specter came up with the name himself when he saw the first operational unit. Macha, so he informed us, was the Celtic goddess of cunning, also known as the queen of phantoms."
"The Celts again," muttered Giordino.
