- <p>Electric cars get a boost in the capital of smog
- </p>
- <p> Battery-powered autos are clean, quiet and remarkably energy
- efficient--but they have a huge problem. Once they get on the
- road, even the most advanced models can travel only 190 km (120
- miles) or so before they run out of wattage, and then they need
- to be plugged into an outlet for about six hours to get fully
- recharged. Now the city of Los Angeles and a California power
- company have proposed a radical solution to the problem of
- powering electric cars: electrify the roads. Last week they
- announced a $2 million demonstration project in which electric
- cables will be run under 300 meters (1,000 ft.) of roadway in
- a west Los Angeles development called Playa Vista. Electricity
- from the cables would be used both to power electric cars and
- to recharge their batteries for travel on conventional roads.

- <p> "It's really very simple," says John Reeves, research
- manager at Southern California Edison, which is putting up half
- of the money (the rest is coming from the Los Angeles
- department of water and power). When electrical power passes
- through a wire, it creates a magnetic field. A metal plate
- moving through that field can, by a process known as induction,
- convert the magnetic force back into electricity. When such a
- metal plate is suspended from the bottom of a battery-run car,
- the vehicle can pick up power simply by moving down an
- electrified road. For maximum performance the plate needs to
- glide within 5 cm to 8 cm (2 in. to 3 in.) of the road's
- surface, which must therefore be unusually smooth.

- <p> Even if Los Angeles' limited experiment is successful, the
- technology will not necessarily be widely used. "This is real
- futuristic stuff," says Sean McAlinden, a researcher with the
- University of Michigan's Office for the Study of Automotive
- Transportation. "It's sort of a Star Wars fantasy." Even
- Southern California Edison officials concede it would take
- billions of dollars and decades of public works to electrify
- the streets of Los Angeles. There may never be electric roads
- in the snowbound Midwest or in Eastern cities subject to the
- freeze-and-thaw cycles that turn the best-made highways into
- roller coasters of bumps and potholes.
- </p>
- <p> Still, the electric-roadway project is generating a lot of
- excitement in pollution-plagued Los Angeles. "I'm thrilled,"
- says Jim Lents, executive officer of the South Coast Air
- Quality Management District, which voted last spring to require
- that all cars in Southern California operate on electricity or
- other clean fuel by the year 2007. "This is what we were hoping
- to stimulate." Automakers have also been tinkering along these
- lines. Peugeot and Fiat have announced plans to sell electric
- vehicles in Europe within the next few years, and Ford is
- testing an electrified model of the Aerostar van. Not to be left
- behind, GM Chairman Roger Smith announced last week that his
- company will proceed with commercial production of its sleek
- battery-powered Impact, although experts say the sedan is not
- likely to reach dealer showrooms before 1995.
- </p>
- <p> Electrifying even a few short stretches of roadway could
- increase the range and effectiveness of such voltswagens
- dramatically. Developers in Playa Vista hope to wire the
- subdivision's two-mile main artery and service the neighborhood
- with all-electric trucks and vans. Edison's Reeves dreams of
- extending the network until it crisscrosses the state.
- Electrifying one or two lanes of a freeway, he says, might be
- enough to keep fleets of buses and cars charged up. People
- wedded to gas-gulping cars could still drive on electrified
- highways, but they might get dirty looks from the new breed of
- battery-powered motorists.
