is it possible to have a flying car?

Rather than someone trying to explain why it won't work, I'd be curious to hear your explanation of how you think it will work. What exactly is the point of the heater and freezer? Why would heating the top of the car/plane and cooling the bottom make it fly?

And how are you going to power these devices, even if they would make it fly (which they won't)?

People always ask about flying cars - they are called airplanes.

Yes and No, yes they can make one because we have flying machines already and with a little modification they can with a car, however, imagine if they were mass produced and a lot of people started buying them.. Everyone would have to start learning how to use one and in America the amount of dumb drivers we have I just don't see it ever happening. Its impractical and I don't think its really what we need..

Yes and probably we would had one if the cold war continued.
