According to Blacksmith Institute Toxic pollution poses health risks to over 100 million people. Moreover with the rising fuel prices there is potential demand for alternative fuel vehicles.Keeping that in consideration french motor company MDI started to build air cars.Even though it is a new concept and there is space for large amount of experiments in this field, Companies started production of cars based on this concept as shown by Sun dial list of 2010 air cars.
As it is still emerging technology, I think this is good project for mechanical students.
Compressed Air Car is car which uses compressed air as its fuel. It uses a concept of steam engine, the only difference is , at the place of steam it uses air.

Students of various universities has started to work on this technology, few of there reports in pdf format are given below :
Northeastern university Compressed Air engine : The EOS
American International University : Use Air as Fuel
