Solar flashlights are a great thing to have in your home and for outdoor activities. They do not require any batteries because they operate off of crank power and they work for lengthy amounts of time. They are also as bright as a normal flashlight.
An average person may keep a crank flashlight around for any use like an average flashlight but wouldn't have to worry about replacing batteries. The crank flashlight is also very handy in situations like a power outage or a camping trip.
There isn't much difference between a crank flashlight and a normal battery powered flashlight besides the way they are powered. For all the batteries you would save not buying batteries for a flashlight it would save the environment that much more.
When the user turns a crank, a small generator inside the flashlight creates electricity that lights the bulb. It accomplishes this using the principal of induction; moving a coil of wire through a magnetic field.
These human-powered flashlights are earth-friendly. A reduction in the number of batteries used means fewer emissions, and there are fewer batteries that must be discarded to fill up out landfills. In a time when consumers are becoming increasingly aware of green alternatives, the crank flashlight makes more sense than ever.
It's perfect for leaving in a glove compartment, under a car seat, backpack, desk drawer, or even in storage areas like an attic or basement. Because the flashlight may or may not have a multitude of attachments, the size may vary. More portable units are much smaller with a smaller bulb and hand crank, while others can be as big as a 2 liter bottle of soda as they carry more than just the flashlight.
Using a crank flashlight saves you money on batteries. It saves the environment by reducing emissions related to battery production and also decreases the volume of consumer waste. And perhaps best of all, it is fun to do. Everyone, from a young child to an elderly grandmother, can enjoy the satisfaction of producing light with his or her own two hands. - 29952
