What you really need is some sort of rechargable battery pack that you can screw onto the underneath of the chair but then uses USB to charge. Regardless of the slow power draw of USB, if you left it on overnight, I'm sure it could charge it up for a good day's use.
That being said, TRON-ifying things is so cliche.
Download or get a hold of a Jaycar cat, plenty of rechargeable battery packs, could also be green and charge it from a solar panel on the back.
