Emissions from vehicles, power plants and other sources cause global warming. As our own fossil fuel sources become depleted, we slowly shift our national foreign policy in favor of those countries that can sell us fuel over those that cannot. As our national exhaust increases year after year, we lose more and more goodwill from other countries, mostly in Europe, that have committed to reduce their emissions levels as per the Kyoto environmental protocols signed in 1996. All these problems in view, we advocate the mandatory exclusive adoption of hydrogen fuel cell engines for all new non-military vehicles sold in the U.S. by the year 2013, and stringent yearly emissions testing for all combustion engine powered cars that remain roadworthy after that date. These new laws are to be enacted and enforced by increased government regulation of the automobile and fossil fuel industries.
Fuel cells are similar to common batteries.
Both were invented in the Nineteenth century by Sir William Grove. Since then, fuel cell technology has improved to the point that it is now a viable primary power source for our transportation. Several cities in the developed world currently run buses powered by fuel cells, including Chicago. We advocate the mandatory adoption of hydrogen fuel cells, since they are totally non-polluting and the cheapest potential source of fuel, but there are several other kinds of fuel cells that would drastically reduce current pollution levels and lessen supply and demand concerns as well. The one great problem with hydrogen fuel cells is that the powering element, hydrogen, is dangerously unstable.
