There is a small generator that charges up a battery. Mine shines fairly brightly with a good charge. you have to rewind it everynow and then but winding is free and very easy. hey when you think about it you burn calories not money.
The FM radio was invented in 1933. It was invented by the inventor Edwin Howard Armstrong. He invented the frequency that allows radios to work.

Yes, the signal will not be interrupted by tall buildings.
In this day and age a hand crank radio would seem rather primitive but there is a lot of room for them in our society. The number one function of a hand crank radio would be access to radio when power is not available. It is perfect for camping trips, hiking, fishing, or even your backyard. Another selling factor is the fact that it does it is completely battery free. Unlike regular radios where you have to feed it mountains of batteries, hand crank radios are completely manually powered.
Windup radios are just as the name says: they are radios in which you would crank a handle on the side going in a circular motion. this then charged the radio so that it would work. so you would windup the radio

The hand crank mechanism in a bicycle works by using a set of gears and a crankshaft to convert the circular motion of the hand crank into rotational motion of the bicycle's wheels. This allows the rider to propel the bike forward by turning the hand crank instead of using traditional pedals. The advantages of a hand crank mechanism compared to traditional pedal-powered bicycles include: Increased power output: The hand crank mechanism allows the rider to generate more power and speed, making it easier to climb hills or ride at faster speeds. Improved efficiency: The hand crank mechanism can be more efficient in converting the rider's energy into forward motion, resulting in a smoother and more controlled ride. Accessibility: Hand crank bicycles can be a good option for individuals with mobility limitations or disabilities that may make it difficult to use traditional pedal-powered bicycles. Overall, the hand crank mechanism offers a unique and efficient alternative to traditional pedal-powered bicycles, providing increased power and accessibility for riders.
