Green Engineering Solutions at Propulsion of Passenger Cars

This paper processes data disclosed by the former and modern sources of literature and presents a study of the current state of art in the field of automotive drives. The paper goes through the different possibilities of storage the alternative energy on a vehicle: electrical energy in lithium based batteries, transformation of solar energy by photovoltaic panels, using of nuclear energy, but each of them presents a lot of disadvantages. Recently promising results appeared using the hydrogen in combination with fuel cells. This is not a new think, but the way of the realization of safety passenger cars offered on the market gives us the hope of a real green engineering solution. We hope this paper contributes to the spread of this technology.
