Honda’s FCX Clarity FCEV is much more efficient than conventional gasoline-powered vehicles 
in converting chemical energy into power. The Honda FCX Clarity FCEV is not an experimental or prototype vehicle.
In gasoline-powered vehicles, fuel (gasoline) is used to heat and expand air, which then drives the engine’s pistons and crankshaft.
Fuel cell vehicles, on the other hand, are much more efficient, because the conversion of fuel (hydrogen) to electricity, used to power the electric drive motor, is a more direct electrochemical process. Water is a by-product.
And since the FCX Clarity FCEV has significantly fewer components in the drive system, no pistons and no camshafts, the energy loss from these systems is eliminated.
Vehicles that use hydrogen fuel cell technology instead of gasoline are about the cleanest around because they emit only water vapor into the air. They also use hydrogen from domestic energy sources, reducing our dependence on oil. And driving fuel cell vehicles significantly reduces the amount of carbon dioxide emissions, helping to slow the increase in greenhouse gases.
To develop a fuel cell vehicle worthy of the Honda name, our engineers worked tirelessly to ensure that the FCX Clarity FCEV was:
* Safe for the public
* Operable in freezing weather
* Able to drive a reasonable range before refueling
* Easy to refuel
* Sporty and fun to drive
* Spacious and comfortable
Hydrogen Safety
Sensors are located throughout the vehicle to provide a warning in the unlikely event of a hydrogen leak. Should such a leak occur, the ventilation system is activated and an automatic system closes the main cut-off valves on the hydrogen tank or supply lines as necessary. The high-voltage lines are electrically isolated. In the event of a collision, the system controller automatically shuts off the flow of hydrogen and electric current. Repeated flood and fire testing have confirmed a very high level of safety and reliability.
Refueling Safety
Honda has taken safety precautions with regard to refueling safety. To prevent reverse flow from the tank, the hydrogen filler inlet has an integrated check valve. The fuel intake mechanism is also designed to prevent contamination by other gases or the connection of nozzles designed for hydrogen stored at incompatible pressure levels.

This Car about 220 Miles between charges before now, electric vehicles typically capped off around 60 miles per charge, relegating them to the status of commuter cars. Tesla Roadster sport car changes all that. Plug it in at night when you pull into the garage and you can drive about 220 miles on that charge the next day.
Well-to-Wheel How can you know, with certainty, how efficient one car is versus another? Tesla conducted a “well-to-wheel” accounting for all fuel efficiency and emissions of several types of high-efficiency cars, including an estimate for the Tesla Roadster car, based upon performance prototypes.
Drive Quickly, Tread Lightly Most electric vehicles operate under the assumption that driving is merely a necessary evil if you need to get someplace you can’t reach on foot or bike. The result has been cars that are designed, built, and marketed in ways that refuse to glorify driving.
speed in seconds without even thinking about it. There is no clutch pedal to contend with and no race-car driving techniques to perform. Just the touch of your foot and you're off, without any of the sluggishness of an automatic.
