It has to be rechargable...and I want to be able to charge it by some sort of self propelled generator.
How do I do this?

Are there any super big batteries that can run a TV for a week and able to recharge it?

The most common solution are large arrays of lead-acid batteries. These are used in large telecom and other systems for backup power in the event of an outage.
I suppose you could use either water or wind for your power generation, depending upon your circumstances. You'll need the battery string, some sort of rectification if your power source winds up being AC generation, voltage regulation and charging circuit -- and in the end, you'll need to pick up an inverter to take your 12VDC back to 120VAC.

In the UK we use lakes, hills and pump/generators. Mind you, it depends on what you mean by 'lots' of electricity. You could scale it down with a pump and a water-tank. You won't get out as much electricity as you put in, unless it rains.
