Have you had any crazy ideas you would like to see on future electric Vehicle? Well I asked myself this question and lately I've been driven mad by this idea, concept...I know it's a stupid idea, it's not suppose to be possible...or if it was that easy for sure someone would have done it and get billion on it by now...But yet, i can't help remove it off my head What if when the car reach a minimum speed of 60 mph it becomes possible to de-activate the Front or Back motor and somehow change the rotation...It would thus become a generator instead of a motor and it would throw back energy in the battery... If you apply Electric power to a motor, you will get mechanical power, but if you apply mechanical power to a motor you will get electrical power...Now I know motors are not efficient generators, and you would have to apply lot more mechanical power to get the same electrical power due to it's low efficiency... and reaching a certain speed it's just doesn't work as a generator... But what if someone designed a motor, that was efficient enough to generate power, and invented that Gear box to use the rotation of the active motor and transform it to a higher speed with the help of this gear box to apply mechanical power to the un-active front motor/generator...-Then in theory that would work because the motor would be efficient enough to generate electric power and provide it to the battery...while that same battery is giving energy to the active motor... That wouldn't be infinite range since at some point you will probably spend more energy than you can provide...but if that idea is possible I think it might drastically improve the range on electric cars... Any ideas? Comments? Is it really that stupid ? lol Any one else thought of other "Stupid Idea" for Electric Cars ?
