Is a self charging electric car possible?
:confused: I was looking at an electric turbine near Cleveland and I thought, "why couldn't an automotive design engineer come up with a similar roof wind generator, for say the new Nissan Leaf all electric car? What about electric generators on the wheels that charge the car batteries as it is driven. This could eliminate plugging the car in at night.
I am sure that this Idea falls into the catagory of a "perpetual motion" machine, but why can't this be done? Why can't they make a self -charging electric car that does not need an engine or electric charging source to replentish its batteries? |

Besides, what electric company in this world would allow that to happen! James |
Re: Is a self charging electric car possible?
:rolleyes: I actually did a web search and found that someone had a patent on the invention for a roof mounted generator back in 1999! I'll try to post a hot link to click on it.
Propeller wind charging system for ... - Google Patents I believe they got a 40 percent charge rate on their home made vehicle, so I assume the vehicle would not be able to run on the fan generator for an indefinite time (would stll need to be plugged into a charger) Edit: A wind powered generator that would be powerful enough to keep the electric car's batteries nearly fully charged, at normal driving speeds would basically be a car that used NO fuel and would appeal to anyone that could afford its high price. One can only dream! |

water powered car. It has the fuel and oxydizer self contained. I'm working on it. gary:rolleyes:

Re: Is a self charging electric car possible?
The demon is friction. Regardless of the closed system, the mathematics of input and out put can never account for friction within the systems. A constant solar recharge might be the only source of energy input that escapes this limitation.
But then the demon would be ugly. BTW: I believe most hybrids and electric cars recapture some energy during braking. This change in momentum can yield free energy. Well, sorta'. |
Re: Is a self charging electric car possible?
The answer is obvious and simple, all roads should be made going down hill.
Why didn't someone think of that before. :p |

Maybe you could charge it with this. :rolleyes:

Re: Is a self charging electric car possible?
I have a friend who worked for Chrysler until he retired recently build a dune buggy electric. He has tried and tried to find a way to charge all those batteries required to move the buggy down the road at speeds up to 65 mph...but, has first fought off the over heating problems, as the motor gets very hot, but has never been able to fully recharge all the batteries at one time... quite a machine to play with around town, but I wouldn't venture too far with it...lol;)

Re: Is a self charging electric car possible?
No such thing as free energy.
The energy to move a car down the road has to come from somewhere - simple physics. And it is not just friction that is your enemy - to charge a battery requires MORE energy than what you got out of the battery in the first place! If you drain, say, 100 amp-hours from a battery, the current required to bring it back to full charge varies from 110 amp-hours to 150 amp-hours depending on battery size. The larger the battery the less efficiency of charge for a given discharge amount. What I am saying is: The charge efficiency is very good when the battery is heavily discharged, but as the charger brings the battery close to full charge - the efficiency drops greatly. In effect, the overall current required to completely re-charge the battery is usually as much as 30% more than the current the battery delivered to the load. Where are you going to get all that energy? You are asking for a perpetual motion machine. |

James Motors, generators, light bulbs, heating elements - all of these have losses. When you convert one form of energy (electricity) into another (kinetic) like in a motor, you have loss in the form of heat and friction in the bearings and inertia of the motor. Again, no perpetual motion machine exists. Pizzaguy (well, perpetual motion from the mother in law's mouth .... hmmmm, maybe she operates at the quantum level?) |

Re: Is a self charging electric car possible?
I have often wondered if small generators could be put on each wheel of train cars that charge batteries on the train engine. It seems like there would be enough axles on a long train to provide useful energy to the engine. Would this be possible?
