A transistor radio typically requires batteries or an external power source to operate, as it relies on electrical energy to function. However, if the radio is designed with a hand-crank generator or solar panel, it may be possible to use it without traditional batteries. In general, without an appropriate power source, a standard transistor radio cannot be used.
Yes; pilots have to be able to use the radio without the engine running and most engines have electric starters so batteries are essential.
Usually, radios have a slot at the back or bottom where you can insert batteries (Often AA). If it does not have a slot, and isn't solar powered or anything, then contact the radio manufacturer, who will tell you how to use batteries. If the radio has to be plugged into a socket outlet and has no slots for any batteries, then the only way you can use batteries to supply it with power is to use an electronic power inverter unit. Several types are available. The most common can use a 12 volt battery and has a socket outlet into which you can plug the radio.
Well I go the old fashioned way, use a transistor radio.

In the house..? Where else are you going to use one. You can also use it outside, anywhere that an outlet is available, or where radio connection is available. If your radio takes batteries, you don't need any outlets.
Most high end radio control cars come with recharable batteries. You can also purchase extra rechargable batteries so you don't have to wait for the battery to charge before you use the car.
The scientists that were responsible for this invention was John Bardeen, Walter Brattain, and William Shockley. Bardeen, with a Ph.D. in mathematics and physics from Princeton University, was a specialist in the electron conducting properties of semiconductors.
Radio communication works by converting sound waves into electromagnetic waves. These electromagnetic waves are then encoded in the radio frequency range of the FM or AM station your are listening to.

Portable radios use double A batteries the most common battery around. There are a few minor ones that take triple A but thats not very common.
A crystal receiver will pick up radio signals within a close range. One must use headphones to hear the signal, as it is generally very weak. A crystal receiver does this without the use of electricity or batteries.
