The means of transportation of the future will be far more expensive, due to abandoning conventional fuel, but will also be a lot safer, as the number of accidents will tend to considerably decrease. Even though the planet"s oil reserves are about to be depleted, people still seem unwilling to forego fast transportation and return to carriages pulled by horses. Which is precisely why researchers have been frantically working on designing means of transportation that are no longer reliant on fuels obtained by processing oil. Electric cars are the first alternative, but in a maximum of 100 years, their technology will be obsolete. Pollution will be far reduced, which will provide ecologists with reasons to rejoice.

The major challenge are solar-powered cars. There are already rallies that such cars participate in, but due to various economic interests, they are still not being mass produced. These means are heavily reliant on weather conditions, but this flaw will be fixed in time. Solar panels mounted on the car"s roof, convert solar energy to electricity. There is a major "problem" because the Sun"s energy potential is huge, which removes several link from the energy supply chain. If all the solar energy that reaches the Earth could be converted, it would be enough to cover the needs of the Earth"s population for a year. The production of alternative fuels using plants is also being studied, the so-called green oil. This is one of the alternatives that current producers like, because it closer to the classical system. Rapeseed, soy and sunflower are the main plants used for producing bio-fuel. The technological process isn"t very complicated, meaning that cars based on bio-fuel will be able to successfully compete with electrical cars. The major problem of these fuels is the fact that many agricultural surfaces will be used for their growth, which will imbalanc
