scooter batteries, recharging, multi source

Hi Everyone:
The scooter part is at the end-excuse my ignorance of this subject, I know zero about electricity.
I am totally new to this. But I am very interested in the potential to use electric energy, as it seems so easily generated.
Probably, because of this, what seems so obvious is ...... not obvious or possible:
A car for instance has the potential to generate a great deal of electricty simply from what it wastes in kinetic energy, wind, friction etc. So, for instance- the alternator creates more that the battery needs, so if you drive a lot- is it not possible to collect the surplus energy (say through the ciggaret lighter) and recharge another 12 v. battery? (even if it is little by little?).
How about mini wind turbines? Has anybody ever created a mini wind turbine that would not create too much resistance (friction) in order to trickle electricity that could help recharge batteries? So it would be like having mini fans behind the grill that would turn and generate electricity?
Now for a seemingly stupid question: I have a mustang GT. Hybrids use brake systems that generate energy instead of the energy being wasted as friction and heat. Are there brake converter kits that can recharge batteries?
Finally- I live in FL. Plenty of sun. Are panels worthwhile? Even if it takes a panel or panels 3 days to recharge a battery/ies
isnt it worth it?
The scooter part: I am considering buying an electric scooter instead of selling my car and buying a hybrid. It seems that through all the above mentioned potentials that I could easily recharge my scooter batteries using a variety of techiniques.
If these ideas are way out in left feild just tell me I dont care. If they are already being used, I would love to know more.
