It would be a great idea except that windmills work by way of wind resistance, and the car would require that much more energy to move.
Along similar lines though: clusters of small "windmills" are sometimes used on the medians of divided highways to gather energy from the wind from passing cars.
Here in SoCal, a garden on a rooftop would be a GREAT idea; lots of sun and the sizes of lawns are laughable here compared to other parts of the country. Solar panels would be nice as well, but I'm not sure they can make enough power to take a house off the grid. Passive systems for heating water seem to be viable though.
The downside to these roof ideas is that appearances are somewhat important here
, and permits would also be required. I could see these ideas working well in Europe and the UK where both people and government are actively trying to do more with what they have.
