Some more information that there were not enough spaces for:
This car is entirely electric (not hybrid, pure electric). To fuel the car you connect the charger plug to a socket on the car that looks like the gas tank on gas-powered cars.
The battery is made of 6831 laptop computer cells (18650 type). A typical laptop battery pack has about 6 of these cells. The battery operates at 375 volts (For comparison, a common AA battery is 1.5 volts, a laptop battery is about 14.8 volts, and wall outlets in the USA are 120 volts) and stores about 56 kilowatt-hours of energy. The battery pack has a mass of about 450 kg.
The motor in the Tesla Roadster is a three-phase motor, as most large electric motors are. The motor only weighs about 70 pounds and can fit inside a backpack. It can safely spin at speeds up to 14000 rpm, allowing one to drive up to 70 mph in first gear.
There are two chargers available:
The fast charger which needs to be permanently wired to its own circuit in the garage by a professional electrician, and the mobile charger which can charge the car from any wall outlet (although slower than the permanent charger).
The base price of the car is about 98 thousand dollars. The car is available with various options (e.g. mobile charger, a nicer stereo, a hardtop) for extra cost.
Tesla Motors is a relatively new car company making only electric cars. It is named after Nikola Tesla, the inventor of alternating current. The roadster is their only car so far, but they plan to release a sedan sometime in 2008 or 2009. You can visit their website at www.teslamotors.com
