I don’t know enough about how this vehicle runs to be able to make an intelligent assessment, but I do know this: the MDI Air Car runs on compressed air. You can’t get any cleaner than that. If only things were as simple as coming up with green vehicle concepts, then this would be a real winner. The company has come out with its own ideas to make this a viable option, however, so props to them for having the foresight to anticipate criticisms and rebuttals. For now, prototypes are available, but it may take a while to be released in the market. You could sign up to receive news about the car’s launch however, and if you’re feeling generous, you may also look into funding the development as well.
