Power!!

For the past couple of days I have been researching different types of generators. Mostly alternative energy generators such as solar powered and bike powered. I am looking for something that will allow me to run a fridge/freezer thingy for 24/7 in my car without having problems. The thing is, I don't know too much about these kinds of things and I have to do a lot of research to make sure that I am going to get the kind that I need for the best price. In addition to the fridge/freezer this will also help to recharge my electronics such as: cell phone, laptop, ipod, and other such electronic devices. Because I am planning to live in my car, this means that the generator has to be small enough so that I can comfortably fit it in my car in addition to my clothes, toiletries, and other necessities and still have a place for me to sleep at night. I have learned about different generators and energy though my research however, If you have any recommendations or input about this, feel free to comment! I would really enjoy to hear what you have to say on the subject.
