TRANSPORTS

TRANSPORTS

Today, transport of persons and goods is made by various means: cars, airplanes, trains and ships pollute now more than ever the atmosphere, the land and the sea aggravating the greenhouse effect, with well-known environmental impacts deriving from irrational burning of mineral fuels.

Fuel types
Which are the fuel types used today? Which of them are the most environmentally friendly? Leaded gasoline is one of the red fuels, since lead may burden human health. On the contrary, ethanol (being one of the “green” fuels) is produced from renewable plantations, such as sugar cane, whereas the quantity of carbon dioxide deriving from its combustion is partly digested by the plantations themselves!

Alternative solutions
Solar vehicles use solar commutators, transforming solar energy to electricity. Apart from solar cars, other types of cars of the future are presented, such as the hydrogen car… hydrogen would be the ideal fuel since its only by-product is water.

It is difficult to convince people to give up their private cars. It would make a large difference for the environment if all people used public transportation more…and from a financial point of view, it would only take a ticket!

Today, about 30 airplanes take off in the world every second, each of them consuming 50 lt of kerosene per mile! By using domestic products (which need not be transported from distant areas) and by reducing some of our journeys (e.g. by developing teleconference) we may all contribute to the mitigation of the transportations problem.
