Abstract
A system and method for powering an ultraviolet (UV) water purification system utilizing a dynamo. A dynamo, operably attached to the UV water purification system, generates power from a rotatable crank which is actuated by a user around an axis of the rotatable crank. When the crank is rotated, the dynamo produces an electrical current that activates and powers the UV lamp, which in turn, produces UV light to purify the water. To ensure that the water has been purified appropriately, a microcontroller, employed within the UV water purification system, tracks both the “on” time and the intensity of the UV lamp as the dynamo is cranked. Once the lamp has been “on” at a sufficient intensity and for an appropriate period of time to administer a required dose of UV light, the microcontroller disables the lamp and provides the user with notification that the process has completed.
