TORCH: Faraday Flash Light
A mechanically powered flashlight, Hand Powered LED, Lamp average life: 10000 hours, is one that is powered by energy created by the user’s physical power and does not require batteries or recharging from an electrical source. There are numerous varieties that have distinct functioning mechanisms. They generate the necessary power using various motions, such as gripping a handle, turning a crank, or shaking the flashlight itself. A spring, a flywheel, a battery, or a capacitor may be utilized to store energy in these flashlights.
Since they are constantly available for use, mechanically powered flashlights are frequently kept as emergency lights in the event of a power outage or other emergency. They are also stored at vacation homes, cabins, and other remote sites since, unlike conventional flashlights, their battery shelf life is not limited. They are regarded a green technology due to the fact that the disposable batteries used in conventional flashlights are inefficient in terms of the amount of energy they produce and contain heavy metals and harmful compounds that pollute the environment.
- Great to demonstrate energy transformation i.e mechanical to chemical to electrical to light energy.
- Requires no batteries. To use torch simply shake it longitudinally.
- This action charges a small rechargeable cell which, in turn, lights the LED’s. When the light starts to dim shake the torch again and full brightness is restored.
- Transparent case means internal parts are visible.
