THE FUTURE OF AUTOMOBILES I n a few years you could be paying much less to fuel your car. Instead of going to a gas station, you might be plugging in your car at night or filling up the tank with hydrogen gas, with both fuels promising big benefits over gasoline. Different car companies are fighting over which fuel will power the car of the future. Who wins the battle will affect your daily life and how you get around, with the days of using gasoline drawing to a close.   Pretty much all car manufacturers are working to increase the efficiency of cars that run on gas. air pollution and contributing to global warming. Even as gasoline-powered vehicles become more efficient with technologies like cylinders that shut off when they are not needed, the engines still pollute the air.   Electric cars promise to not pollute the air at all. The only problem has to do with how the electricity used to charge a car's battery is generated. Many people get their household electricity from a plant that burns coal, which produces even more pollution than using gasoline. Other methods for generating electricity, like constructing dams, are also negative for the environment. A “Electric cars promise to not pollute the air at all” Car companies arguing for electric cars include BMW, Tesla, Nissan, General Motors and Kia. Advocating for hydrogen as the fuel of the future are companies like Toyota, Honda and Hyundai. Some automakers like Ford are exploring both electric and hydrogen cars as they wait to see what the future holds.   Environmental Impact   Burning fossil fuels negatively impacts the environment, increasing 14 CLARITY MAGAZINE march 2014 growing number of electric car owners are taking it upon themselves to generate their own electricity by installing solar panels on their roof, ensuring the operation of their car truly generates no pollution.   Hydrogen cars also put off no pollutants, with only water vapor coming out of the tailpipe instead of smelly exhaust. Right now the way to produce hydrogen is with electrolysis, or electrifying water. How that electricity is produced determines if using hydrogen as a fuel creates pollution or not.   The Real Cost   According to Nissan, an electric charging station installed at a house costs around $2,200. At the moment, charging the typical electric car costs about $2 to $4, making driving an electric car much cheaper than driving one that is powered by gasoline.   Early estimates for the cost of hydrogen are somewhere between $2 and $4 per kilogram. A kilogram of hydrogen will take you further than a gallon of gas, making hydrogen less expensive. International war or terrorism would not affect the cost of hydrogen or electricity, making prices fairly stable over time.   The Future of the Automobile   Electric cars are catching on quickly after struggling with slow sales at
