Do you want to buy a car that runs on water? Well this might have sounded weird a few years ago, but not anymore. To defeat the growing threat of air pollution, scientists have actually developed cars that use 100% water as fuel. What’s more, these cars are possibly the vehicles of the future, in an age when gasoline and diesel cars will become obsolete and relegated to museums.
Cars that run on alternative energy sources are the latest craze in the automotive world. In fact, scientists have developed cars that run not only on water, but also on other unconventional energy sources such as electricity, solar energy, biodiesel, ethanol, and LPG. This is a necessity, considering the depletion of fossil fuel stocks and increasing pollution levels in the world. In this article, we take a quick look at the various advantages and disadvantages of cars powered by alternative energy sources.
To date, the most popular form of alternative energy that has been used to power automobiles is electricity. Cars like Toyota Prius and Honda Insight can run on both electricity and gasoline. These cars, labeled as hybrids, contain an electric motor in addition to the normal one, giving the driver the option of choosing the power source. Compared to other cars, hybrids are more environmentally friendly and are also cheap to drive. Hybrid electric vehicles contain batteries that can be charged with a standard household electrical outlet.
The use of LPG and CNG has also been promoted by various governments in recent years to reduce the emission of greenhouse gases. CNG powered cars are extremely fuel efficient and produce very low levels of emissions. It is possible to convert a conventional gasoline engine to a CNG-compatible one by using a simple hybrid conversion kit, giving gasoline car owners the opportunity to reduce emissions levels.
In addition to these, much research has been done in recent years in the development of cars that run on solar energy and biodiesel. While the former generally collects energy from the sun using solar panels on its body, the latter uses fuels derived from natural and renewable energy sources, such as plants and vegetable oils. Astrolab, designed by French transportation futurists Venturi, is the world’s first commercially available solar-powered car. Solar powered cars have zero emission levels and are ideal carriers for a pollution-free world. However, solar car development is still in its early stages and we don’t have a solar powered heavy vehicle on the roads yet. On the other hand, biofuel-powered cars are easier to make, but their popularity has been proven due to the limited availability of biofuels.
The water-powered car is also one of the possible solutions that scientists have found to meet the challenges of increasing air pollution. This car uses the electrolysis technique to divide water into oxygen and hydrogen, thus generating the energy required in the process. Although it is a totally pollution-free vehicle, the water-powered car is expensive to manufacture and research is still being done to make the car commercially viable.
However, what is promising is the enormous interest that hybrid cars have generated among people around the world. With the depletion of oil stocks and rising fuel prices, intense research and development is going on in the development of cars that run on alternative forms of energy. The increase in air pollution and the greenhouse effect has also contributed to the search for a profitable and non-polluting car. In fact, we are not far from the day when the perfect green car is a reality for consumers. Hybrid cars are indeed the vehicles of tomorrow and they are here to stay.
