Photos: Tesla Roadster ready to hit the streets

Shown here is the battery. It consists of approximately 6,800 lithium-ion battery cells. Your notebook computer probably has six similar cells. The battery pack has been designed so that a "runaway thermal reaction," or fire, won't occur if one battery cell overheats.

The car chassis gets built in England but the battery comes from Taiwan.
