Any genius who can make life more easier. Suppose, when you need a ride to go somewhere, you don't have money or anyone who can help you with that, you don't even have anyone who can give you a lift then how do you think you can get there. Then you can use this cheap car that can be driven by only water or half an hour electric or solar charged battery or simply your old newspaper could be handy at this point. Is there any cheaper brilliant out there who can make this kind of car. If you have money then you can take other options.
