  The aim of this contribution is to define the effects of a new alternative diesel fuel mixture. Comparative measurements were carried out, by using normal diesel fuel, and alternative mixture. Vegetable oil and normal diesel were used to fabricate the new oil mixture. In this study the measurements and the analysis of the results will be presented. To compare the effect of the two fuel, diagrams were used.

  The undiminished development of air traffic has a direct effect on the environment of airports. Year in year out the continuously growing passenger traffic has increased the number air flights. The technological development has made it possible to increase the size and performance, - and with it the transportation of heavier payload - of aircraft. Of course, it has necessarily resulted in more fuel use (burnt fuel) emitting more pollutants into the atmosphere. In addition this effect appears not only during the high altitude flying polluting the high atmosphere, but due to the today very busy and the continuously increasing ground aircraft motion (taxiing) contaminating the close surroundings of the airport. With some innovation and technological development we can make the airports not only more environmentally friendly but also cost effective. In this paper I would like to introduce the possible use of renewable energy sources and the ground movement of aircraft without their own engines.

  This paper presents the Life Cycle Assessment of the wood gas powered car. I have compared the results with the data of the gas powered cars. The wood gas powered cars will be presented from their invention up to this day. I will describe in detail the chemical composition of different types of trees, the heating value and the reaction equations of gasification. I have made a cost analysis and I have concluded that if wood gas is used as petrol, the costs can be reduced significantly.
