Palo Alto, California (CNN) -- In the 1990s, a researcher named Kris Pister dreamed up a wild future in which people would sprinkle the Earth with countless tiny sensors, no larger than grains of rice.
These "smart dust" particles, as he called them, would monitor everything, acting like electronic nerve endings for the planet. Fitted with computing power, sensing equipment, wireless radios and long battery life, the smart dust would make observations and relay mountains of real-time data about people, cities and the natural environment.
Now, a version of Pister's smart dust fantasy is starting to become reality.
"It's exciting. It's been a long time coming," said Pister, a computing professor at the University of California, Berkeley.

Tod Dykstra looks out from his downtown San Francisco office window every day and sees waste. While a parking garage next door sits empty, roads are clogged with cars in search of cheaper metered spots on the street. "Thirty percent of driving in cities is made up of people who have gotten where they want to go and are looking for parking," Dykstra says. "Think about all those carbon emissions. It just doesn't seem right."
Dykstra, founder of Streetline Networks, a San Francisco company that makes traffic-control technology, wants to make it tougher to park cheaply or get away with not feeding the meter. Streetline's system lets parking authorities identify crowded streets and jack up parking-meter rates block by block. The idea is to encourage drivers to stop circling and get off the streets—either paying for a municipal garage or heading to a less crowded neighborhood. San Francisco and Los Angeles are now installing Streetline technology.
Unlike anticongestion programs in London and Singapore, which rely on cameras and in-car devices called transponders to bill drivers as they enter crowded areas, Dykstra taps streets for data. Low-power magnetic sensors about the size of a palm are embedded in roads to detect cars in parking spots or driving. Those data are wirelessly transmitted to devices on top of streetlamps or traffic-signal boxes, which send the data to parking authorities. If a street has high traffic and no parking spots, the San Francisco Municipal Transportation Agency's SFpark program plans to raise meter rates up to $6 an hour. The prices will show up on meters and the city's website.
