Darryl Barton and Elliot Reed joined forces and built this magnificent beast
It was invented by Conrad Hubert in 1902.
Conrad Hubert invented the flashlight in USA.
Conrad Hubert invented the first Eveready branded flashlight in 1898, not Zeus invented something in 1936.
The flashlight was invented in the late 19th century, around 1899, by British inventor David Misell. He patented the first ever flashlight design, which used a battery, bulb, and a small incandescent light in a tube.
The first hand-generated flashlight was invented in 1899 by British inventor David Misell. It used a dry cell battery and an incandescent light bulb to produce portable light.
The hand-crank flashlight was invented by Ann Makosinski, a Canadian inventor, when she was still in high school. The flashlight generates power through kinetic energy created by hand cranking, eliminating the need for batteries.
Hand crank flashlight
A hand crank flashlight typically uses mechanical energy from your hand turning the crank to generate electrical energy, which charges a rechargeable battery or capacitor. This electrical energy is then used to power the light emitting diode (LED) in the flashlight.
A dynamo flashlight works by producing its own electricity. The flashlight has a crank that is turned by the operator. The crank runs a small generator inside that produces enough electric to run the flashlight.
This was discovered where there was no electric due to the earthquake. This can be used without any batteries or recharging it whenever the battery is low. It is powered by the muscle power of the user and it has many types.
"Go through"? The process of charging and using a crank flashlight includes the existence of thermal, mechanical, electromagnetic, sound and radiation energy.

A mechanically powered flashlight , such as those with crank handles.
When a hand-crank flashlight is operated, the mechanical energy from turning the crank is converted into electrical energy, which is then converted into light energy by the light bulb in the flashlight. This demonstrates the transformation of mechanical energy into light energy through intermediate electrical energy.

Crank flashlights are very handy devices that are particularly useful in a pinch. No need to worry about charging the flashlight or ensuring it has fresh batteries, the crank flashlight is a great last resort and will always light up your campsite when you need it.GeneratorThe crank flashlight contains a small generator much like the ones that are used to provide electricity around the country. The difference is that the flashlight's generator, also called a dynamo, is powered by manual cranking of the arm.InductionThe principal behind the generator is that of induction. When you move a coil of wire through a magnetic field, a voltage is induced into the wire, which then creates electrical current that flows through the circuit. Inside your crank-powered flashlight is a wire coil that is inside a magnetic field. When you crank the arm of the flashlight, you are actually moving this coil in the magnetic field. As the coil moves, voltage is induced and current then flows through the circuitry and lights the bulb of the flashlight.BatteriesYou've probably noticed that you can crank your flashlight for a few minutes and then get a reliable light source for a while afterward without actively cranking. This is because the crank flashlight has rechargeable battery cells inside that store the energy that you've created from cranking. In this way you don't have to actively crank to use the flashlight, but can crank and then have the flashlight operate on batteries.Read more: How Does a Crank Flashlight Work? | eHow.com http://www.ehow.com/how-does_4911443_crank-flashlight-work.html#ixzz1Xz4cG0feELEPHANT!
