Cars of the Future
More than 95% of the transportation systems around the world are fueled by petroleum. A quarter of all the petroleum ever consumed in the history of the world, was consumed in the last ten years, and that trend is accelerating.
Most cars on the road today (800 million cars) are fueled by petroleum. By 2050, projections are that there will be 2 billion vehicles on the roads. There will be an energy shortage and soaring gas prices in the future. Car companies are working on new technologies for the “cars of the future,” with alternate fuel such as ethanol and biofuel, and solar powered cars. Hydrogen powered cars are also under study.
Cars of the future must be reliable, practical and safe. In order to be reliable, it must be easy for them to be refueled. At the moment, gasoline stations are ubiquitous. Locations to fill up with hydrogen are very rare. The system will have to change in the future.
