Our design is a hand-crank powered water heater. By rotating the hand-crank, a plate containing magnets is spun using the gear train connected between them. The spinning magnets induces a charge in the aluminum plate above which is used to heat the water contained above the aluminum plate producing hot water.
Our design uses the concept of induction to work. What is Induction?
Induction refers to the process of generating electrical currents through electromagnetic fields. One popular use for induction is the induction cooker which is used in cooking.
While related to the induction cookers available in the market our design utilizes the concept very differently. Instead of an electromagnetic coil to induce charges into a metal surface above we use spinning magnets instead.
In our design we have created a circular plate with equidistant holes on the outer side of the plate. In these holes we fit in N52 circular magnets with the magnet in each hole being of opposing polarity. By spinning this plate, we create a fluctuation in magnetic field strength which through the explanation of Faraday’s law of induction generates an electric field which then induces charges in the aluminum plate above creating heat in it. Water rests above this aluminum plate and is heated by the aluminum plate producing hot water for us.
