Self powered radios are a reality, but there are not sold because frankly they suck. All you need is an antenna, coil capicator, product detector (germanium diode, or razor blade) hook it up to a set of crystal earphones and you can listen to the radio. just do a search on google for "fox hole radio". It is what soldiers in WW2 used.
