all-expenses-paid ringside seat to scope out the century's most promising new technologies.
The work here was right up his alley. The word nanotech carried an incredibly wide range of meanings. At its most basic, it meant the creation of artificial devices on the smallest of imaginable scales. A nanometer was just one-billionth of a meter, about ten times the size of an atom. Make something ten nanometers across and you were still looking at a construct that was only one ten-thousandth of the diameter of a single human hair. Nanoteclmology was engineering on the molecular level, engineering that involved quantum physics, chemistry, biology, and supercomputing.
Popular science writers painted glowing word-pictures of robots only a few atoms across prowling through the human body - curing diseases and repairing internal injuries. Others asked their readers to imagine information storage units one-millionth the size of a grain of salt yet able to hold all human knowledge. Or dust motes that were actually hypercapable atmosphere miners, drifting silently through polluted skies while scrubbing them clean.
Smith had seen enough during his weeks at the Teller Institute to know that a few of those seemingly impossible imaginings were already hovering right on the edge of reality. He squeezed his car into a parking space between two behemoth SUVs. Their windshields were covered in frost, evidence that the scientists or technicians who owned them had been in the labs all night. He nodded appreciatively. These were the guys who were working the real miracles, all on a diet of strong black coffee, caffeinated soda, and sugar-laced vending machine snacks.
He got out of the rental car, zipping his jacket up against the brisk morning air. Then he took a deep breath, catching the faint smell of cooking fires and cannabis on the wind wafting across from the protest camp. More minivans, Volvo station wagons, chartered buses, and hybrid gas-electric cars were arriving in a steady stream, turning off Interstate 25 and heading up the access road toward the Institute. He frowned. The promised multitudes were assembling.
Unfortunately, it was the potential dark side of nanotechnology that fed the terrified imaginations of the activists and Lazarus Movement zealots gathering outside the chain-link fence. They were horrified by the idea of machines so small they could freely penetrate human cells and so powerful that they could reshape atomic structures. Radical civil libertarians warned about the dangers of "spy molecules" hovering unseen in every public and private space. Crazed conspiracy theorists filled Internet chat rooms with rumors of secret miniaturized killing machines. Others were afraid that runaway nanomachines would endlessly replicate themselves, dancing across the world like an endless parade of Sorceror's Apprentice enchanted brooms - finally devouring the Earth and everything on it.
Jon Smith shrugged his shoulders. You could not match wild hyperbole with anything but tangible results. Once most people got a good close look at the honest-to-God benefits of nanotechnology, their irrational fears should begin to subside. Or so he hoped. He spun sharply on his heel and strode toward the Institute's main entrance, eager to see what new wonders the men and women inside had cooked up overnight.
Two hundred meters outside the chain-link fence, Malachi Mac-Namara sat cross-legged on a colorful Indian blanket laid out in the shade of a juniper tree. His pale blue eyes were open, but he sat calmly, without moving. The Lazarus Movement followers camped close by were convinced that the lean, weather-beaten Canadian was meditating - restoring his mental and physical energies for the crucial struggle ahead. The retired Forest Service biologist from British Columbia had already won their admiration by forcefully demanding "immediate action" to achieve the Movement's goals.
"The Earth is dying," he told them grimly. "She is drowning, crushed beneath a deluge of toxic pesticides and pollution. Science will not save her. Technology will not save her. They are her enemies, the true source of horror and contagion. And we must act against them. Now. Not later. Now! While there is still time . . ."
MacNamara hid a small smile, remembering the sight of the glowing faces fired by his rhetoric. He had more talent as an orator or an evangelist than he ever would have imagined.
He observed the activity around him. He had carefully chosen this vantage point. It overlooked the large green canvas tent set up as a command center by the Lazarus Movement. A dozen of its top national and international activists were busy inside that tent - manning computers linked to its worldwide Web sites, registering new arrivals,
