Networking software developed by Agassi's programmers will coordinate the whole system, which is called a "smart grid."
The plan is to set up service stations that will pull out and replace spent lithium-ion phosphate batteries in about the time required to fill a car's tank with gasoline. The company's wireless
network will tell drivers where they can get batteries replaced.
Agassi hopes to pilot the project in a few countries next year and begin mass deployments in 2010. He says he's close to signed agreements with several car companies and countries.
