A while back, some folks were looking for a solution for getting TV news either on the move or when power was out. There was concern that this would become more difficult with the new digital TV broadcast formats.

I just found this: http://www.ecost.com/p/Axion-Consumer-Electronics/product~dpno~8764268~pdp.ghjaiai?source=EWB08130

While I have no idea how well this works, and I'd rather have user-replaceable batteries, for $35 it seems worth a try. I'll report back one I receive it. Worst case, it will amuse my kids on road trips!
