The advantages of using television for education are the TVs keep students' attention better than books, and it is more fun than books. The disadvantages are that the students cannot interact with a TV, they do not know where the information came from, and they cannot always re-watch shows for missed information.
According to my uncle who is James Reynolds son."the alarm quit working on his wind up clock... so he rigged the key on the back of the clock to the volume knob on the radio. when the alarm started going off, the key would spin around and turn the volume up on the radio."

The advantage is that wind is renewable- it does not get used up. Disadvantages- the wind does not always blow, it does not blow at a constant speed, and it does not always blow where electricity is needed. It can be costly to generate and store electricity from wind energy.
Solar powered radios will last far longer than wind-up radios, provided there is adequate sun.
The wind-up radio was invented by a British man - Trevor Baylis. It is wound up by an integral handle, which winds a mainspring (a larger version of the mainspring found in a watch. The spring slowly unwinds, turning an internal generator - which powers the radio. See related links to Wikipedia pages on the inventor - and the radio.
