If supposing we were to add a wind turbine connected to a generator to a moving car, would we be able to get the air flowing around the car to turn the turbine and therefore gain some energy? If it is possible, is it economical? if it is, is it practical? would there be a loss? would there be any gain in overall efficiency
That depends what you mean by “wind”. It is certainly possible to attach a sail to a set of wheels and have the ambient wind blow you around. That would cetainly be efficient.
On the other hand, if you mean the wind generated by the car moving through the air, then the engine creates that motion by moving the car forward. By capturing that wind to extract energy, you are slowing the car down and making the engine work harder. Even using the energy you extract, you will use *more* gas than you do now. That is to say, the system is less efficient than existing cars

It is possible to do so, by connecting a wind turbine to the car battery to charge it. However we don’t do this as it is very inefficient. It would actually take a very long time using wind energy to charge up a car as wind energy isn’t very efficient. For example, charging up the Tesla electric car would take 600 hours, around 25 days on a personal wind turbine. We cannot use wind energy for cars as it is unreliable (wind always varies each day) and doesn’t produce enough energy fast enough to charge car batteries within an adequate time period. See the link below if you want to see an electric car review which also shows problems with them (Top Gear, BBC).

yes u can easily make a mini wind turbine to charge a battery in an electric car

You could have a wind turbine powering a generator at your home and plug in your electric car there. http://www.wirefreedirect.com/wind_turbines.asp
You could use the same wind turbine to directly compress air for a compressed air car and power your car that way: http://www.ecogeek.org/automobiles/659
You could have a wind turbine that you could set up when you are parked and charge your batteries that way. http://www.evconvert.com/article/peters-solar-electric-van
You could even attach a sail to your car and move it along that way, although it might be a bit awkward in traffic. http://www.youtube.com/watch?v=HLKnO47Epks http://www.treehugger.com/files/2009/03/fastest-wind-powered-car-world-greenbird.php The same vehicle could use the same kite sails that are used for Kite boards.
But you could not expect to get energy from the “wind” caused by a car moving. In this way you would be tapping into the car’s inertia and such a generator would tend to brake the vehicle somewhat less efficiently than the regenerative braking that is used now.

first, if you had an electric car, it wouldn’t matter what made the electricity that was used to charge the battery.
however, if you want to use a windmill mounted on the car, you’d have to be satisfied with a car that went 1-2-3 mph at the most. and that, only when it was windy. there are several problems.
1. wind energy is lower, down low to the ground.
2. mounting a tall windmill wouldn’t work, the first time you came to an underpass.
3. considering you have to have a relatively small, low, windmill, when you were driving against the wind, the wind would try to drive you backwards.
4. there are lots of days when there just isn’t enough wind to do any good at all.
5. in the city, the wind is really erratic. that would be a problem.
6. any such structure would need to be very light. which would make it fragile. a couple days ago, someone bent over my radio antenna. one can only imagine.
that should be a start.

Sure, if you only drive down hill. Otherwise, we’ll be burning gasoline for the rest of our lives.

Quick answer: of course!
An EV or plug-in hybrid car is charged with electricity, and electricity can be generated by any means — solar, wind, nuclear, hamster…
If you’re talking about having some kind of small-scale wind turbine on your property, as is becoming increasingly common with solar PV, then there could be problems. Mainly because wind works best with the really massive turbines that are up hundreds of feet in the air. A small turbine on your property can work, but its fast-spinning blades would be a real bird blender, and you’d need the extra land to place it on. Putting it on your roof can run into problems mainly because you’re adding stresses to the structure of your house that it wasn’t designed for. If it’s big enough to produce a useful amount of power, then in high winds it could apply some significant lateral force. You’d also have to keep clearing the bird body parts from your roof.

no, why? because your garage has no wind to get your car out
but wind provides too little energy, even solar panels provide only little input for EVs. you can however get a wind turbine for your house given your in a wind rich area to charge your EV. but prepare to tolerate wind generator noise, and may be dead birds one a while

yep, i think it is possible unless and until if you use a solar powered battery to your car…
