The problem is that your light would go out if you were not moving. Batteries allow the light to remain on even when you are not moving and turning the dynamo.
A bicycle dynamo light works by using the rotation of the bicycle wheel to generate electricity. This electricity powers a light bulb, providing illumination while cycling.
To provide electricity for the bike lights without having to rely on batteries.
It's your basic electromagnetic device. Pressing the pickup wheel of the dynamo against a bicycle wheel in motion cause the inner parts of the dynamo to spin. What's spinning is a pair of magnets surrounded by coils. When the magnetic field through a coil changes you get electricity. That electricity can then power a light.
Yes, a lightning bolt can provide electricity because a lightning bolt is electricity.
Electricity
Disadvantages of DC: * High power transformation of voltage is less convenient than AC. AC uses a transformer. * DC does not have the natural break in transmission that AC has (zero twice per cycle) and does not switch off as easily * DC does not provide time to synchronous clocks * DC dynamos or generators are less efficient at converting input power to output electricity than AC alternators. That is why altenators with rectifiers are now used in vehicles instead of DC dynamos.
I can list the different bicycle parts for you, but I am unable to provide pictures. Some common bicycle parts include the frame, wheels, tires, handlebars, pedals, saddle, brakes, gears, chain, and crankset.
To do bicycling you need a bicycle. And the bicycle is a man-made item relying heavily on techology to provide all the bits and pieces.
The population of the area is a big factor into where they provide service. It all depends on what they are using to provide electricity also.
StarTex Power is a Texan electricity provider. As such, their main service is to provide customer service and electricity to its clients and customers.
Directly - no. But you can get electricity from sunlight if you let it shine on a photovoltaic cell.
