Create some kind of energy source/aparatus that when shaken or spin/rotated in the rims/wheels it produces energy, the energy could be used as fuel for the car, making the car never stop for gasoline or recharge itself....

or some kind of pendulum type of technology recharing every second going in the rims....

I know you are saying, that: Oh my gosh nobody will pay for gas anymore...Want to know something...I´ve learned that if you came out with a car where you dont have to put gas on it anymore, EVER but the car looked ugly and you offered it to the public, some like few people will DRIVE IT....YOu have to learn the basic...WHY PEOPLE BUY CARS???Because is a symbol of SEX AND IMAGE...YOu are laughing, but ask yourself the question...IF PEOPLE WANTED, all the population of a country/state pitch in money and they will buy themselves, ALL THE BUSES, MINI BUSES and taxis in the world and not have to pay for transportation anymore...Why dont they do it???...Because a car is a symbol of sex and image....and confidence too....JUST SO YOU KNOW...maybe in an extremely poor country but the rest of the world will not buy it...

it goes back to an age old question: WILL YOU WALK NAKED OR SEMI NAKED EVERYDAY...WILL YOU GO TO WORK SEMI NAKED OR NAKED....
Nobody should walk naked, but in this little planet: Image is a big issue...JESUS HAS TO BE BLOND OR BLUE EYED, kid´s clothes got to look better than grown ups, ect....IS A BIG ISSUE....

i suggested the idea more for: NASA space transportation....AND HAS TO BE INVENTED FIRST TOO....
