The whole world is familiar with the financial crisis in Greece. Unemployment has reached a percentage of 25% and poverty keeps growing. Besides that prices keep raising, and access to petroleum for heating next winter will be very difficult for some Greeks. I have read an article for a British company which has developed a machine that turns used oils from restaurants to diesel. A liter of diesel nowadays in Greece costs approx. 1 euro and the estimation for next winter will be 1,5 euros/ltr. With this method the diesel costs 0,22 euro/ltr which makes it significantly cheaper for poor people. So my idea is about making a social gas station which will produce bio diesel only for poor, unemployed, sick and handicapped people in Greece. A good side effect of this action would also be to environmentally manage a large amount of used oils which would otherwise be freely disposed to environment.
