Why cannot similar more technologically advanced technology be applied to EVs so when the wheels are turning, they are charging at the same time?
They can do, but not at the same rate, so there'll be energy loss. I'm no expert but from what Physics I did learn, there's the conservation of energy theory etc. Due to loss of energy through heat, friction, light, sound, etc., you can never usefully keep all the energy you produce because some is inevitable lost in ways that aren't useful to you, so whilst you can use dynamos etc to preserve some of the energy used, it'll never be as much nor more than the energy used to move the car in the first place, unless you're always driving downhill, when you gain energy due to gravity, but since you normally have to use energy to get uphill in the first place, you'd be just re-gaining some of the energy used getting up whilst you're going down again. Of course, whilst you're going downhill or coasting on a straight road, the amount of power you are generating may well be wasted anyway if the batteries are already full as they can't be charged any more than their capacity.
