Sacred writting: If I could invent something what it would be and why?

If I had a chance to invent sometning it would probably be a mashine that could save our planet from polution, it would vacuum the poluted air and det rid of it inside itself. Also, this gadget should collect rubbish and convert it. I would do this because environmental polution is a very acute question nowadays. It influences all the possible illnesses, including lungs cancer, it effects on our appearance (I mean skeen , hair), we feel depressed, tired,dissatisfied. Probably, it worths to create a peaceful, abandoned place, somewhere in the middle of the ocean, where all tired people would spend several days or, for very extraordinary and unpredictable cases, even months without any material and technical wealths of humanity. A place, where people would feel safe, calm, protected. Moreover, there wouldn't be any factory, cars, computers in order to protect people from the hurmful radiation waves.
